ARMED SERVICES BOARD OF CONTRACT APPEALS 
 
OPINION BY ADMINISTRATIVE JUDGE D’ALESSANDRIS 
 
The United States Air Force (Air Force or government) entered into a contract 
with appellant, Chromalloy Component Services, Inc. (Chromalloy) for the 
remanufacture of low pressure turbine assemblies for F108 aircraft engines, 1 used on 
KC-135 military cargo aircraft.  As part of the remanufacture process, Chromalloy 
inspects the 174 stage 1 blades and replaces blades when necessary.  Prior to the 
contract at issue, the government permitted the use of commercially serviceable (used) 
fan blades at a cost of around $100 per blade.  At that time, the cost of a new original 
equipment manufacturer (OEM) blade was around $1,700.   
 
The engine manufacturer subsequently provided revised guidance requiring 
replacement of certain fan blades.  As a result, the solicitation for the contract at issue 
required the use of new OEM fan blades.  Coincident with the revised manufacturer 
guidance, and predating the submission of bids on the contract, the price of OEM fan 
blades increased from approximately $1,700 per blade to $5,100 per blade.   
 
Due to concerns regarding the price and availability of stage 1 blades, the 
government modified the contract such that bidders were required to propose a price 
for stage 1 blades for the base year, but the option year pricing was listed as to be 
determined.  Chromalloy was awarded the contract, with a fixed price of $5,202 per 
stage 1 blade.  However, the price of stage 1 blades continued to increase, reaching 
$5,655 per blade.  The government subsequently modified the contract to make the

blades government furnished material (GFM), but not until after Chromalloy 
purchased a large number of blades for inventory.   
 
Chromalloy appeals from a Contracting Officer’s Final Decision (COFD) 
denying its claim for additional compensation due to the government’s purported 
failure to share superior knowledge regarding pricing of the stage 1 blades; the change 
from contractor furnished stage 1 blades to government furnished material resulting in 
residual inventory; and a change to the course of dealings between the parties when the 
government placed a large order near the end of the base period, rather than ordering at 
the higher option year price.  The Board held a virtual hearing where both parties 
presented evidence and testimony.  We deny Chromalloy’s appeal for the reasons 
stated below. 
 
FINDINGS OF FACT 
 
On January 17, 2019, the Air Force Materiel Command posted Request for 
Proposal No. FA8122-19-R-0001 (RFP) on the Federal Business opportunities website 
(R4, tab 1 at 1).  The RFP sought the complete remanufacture of USAF Module 13/15, 
which is part of the Low Pressure Turbine (LPT) major module of the F108 engine 
used on the KC-135 aircraft (R4, tab 101 at 1).   
 
At the time of the solicitation, Chromalloy was the incumbent contractor, and 
had performed F108 aircraft engine contracts dating back to 2004 (tr. 13-14, 35).  
Remanufacture of the LPT module involved tearing down the engine and replacing or 
repairing component parts, including the LPT Stage 1 blades (tr. 15, 23).  The engine 
manufacturer CFM International (CFM) is a joint venture between Safran Aircraft 
Engines (Safran) and GE Aerospace (GE) (tr. 16).  Around 2012, CFM issued a 
service bulletin indicating that certain blades, identified by serial number, were suspect 
and should be replaced (tr. 32).  The concern was that the suspect blades could 
de-latch from the disk causing internal damage to the engine (tr. 91). 
 
There are 174 LPT stage 1 blades in each engine (tr. 33).  When a blade needed 
to be replaced, either because it was damaged, or was on the list of suspect blades, the 
predecessor contract permitted Chromalloy to use commercially serviceable blades – 
that is, commercially flown blades from civilian equivalent CFM56 engines (tr. 33).  
The commercially serviceable blades were available on the market for around $100 per 
blade, while a new OEM blade was priced around $1,700 per blade (tr. 15, 33).  Over 
time, additional service bulletins increased the number of suspect blades, creating 
supply issues with replacement blades (tr. 32-34).  During the solicitation period, 
Chromalloy had discussions with Aviall, the OEM part distributor, and learned that the 
price of new OEM blades was increasing from around $1,700 per blade to $5,100 per 
blade.  As was the case for the prior contract, the RFP initially permitted the awardee 

3 
 
to use commercially serviceable parts but was later amended to require new blades.  
(Tr. 34-36; R4, tab 11 at 2) 
 
The RFP provided for a 1-year base period, plus four 1-year option periods (R4, 
tab 1 at 5).  The RFP initially had a single priced Contract Line Item Number (CLIN), 
which was for a complete remanufactured unit, including all parts and labor (id. at 6).  
Chromalloy filed a pre-award protest with the Government Accountability Office 
(GAO) on March 6, 2019, alleging the government failed to accurately describe its 
requirements by not including historical data as part of the RFP, and alleging that the 
single CLIN encouraged unbalanced pricing (R4, tab 89 at 1).  Following discussions 
with the government, Chromalloy withdrew its protest on March 12, 2019 (R4, tab 90 
at 1). 
 
In response to issues raised by Chromalloy and other vendors, the government 
amended the RFP and Statement of Work (SOW).  Amendment 0007 added a 
SubCLIN for the blades, X001AA (where X designates the base or option year).  (R4, 
tab 11 at 2)  Amendment 0008 modified the pricing structure so that offerors were to 
propose a price for 0001AA (the base year), but the option year SubCLINs were 
amended to read “TBD” or “To Be Determined.” (R4, tab 14 at 2).  Amendment 0008 
also added the following language to each option year SubCLIN for the blades:  “Upon 
exercising an option, the Government reserves the right to negotiate option year unit 
pricing or provide new blades as Government Furnished Material (GFM).” (id. at 8, 
10, 13, 16).   
 
On August 5, 2019, Chromalloy filed an additional pre-award protest with 
GAO alleging that the RFP contained a requirement that was impossible for any 
offeror to meet (R4, tab 91 at 1).  Specifically, Chromalloy alleged that new blades 
were not available to purchase at any price (id. at 5).  The GAO denied Chromalloy’s 
protest on November 6, 2019 (R4, tab 92 at 1).  The government received 
Chromalloy’s proposal on December 5, 2019, and awarded Contract No. FA8122-20-
D0002 to Chromalloy on April 17, 2020 (R4, tab 19 at 1). 
 
Chromalloy contends that the government provided assurances, prior to contract 
award, that OEM blades would be available at $5,100 per blade during the base year of 
the contract.  Sam Malone, Chromalloy’s lead of military practice during the 
solicitation period, testified that the government had provided information on what the 
blade pricing would be, however, he also admitted that he had not received the 
information directly from the government, but instead through another Chromalloy 
employee, Ms. Mackell (tr. 11, 18, 28-29).   
 
Ms. Tamara Mackell, Chromalloy’s senior government contracts manager, 
testified that Chromalloy had received assurances from the government that the price 
of the blades would be stable through the base contract year (tr. 30, 39-40; R4, tab 94 

4 
 
at 3-4, 6-7 (Chromalloy’s claim discussing such assurances)).  Ms. Mackell also 
testified regarding a June 17, 2020 telephone call with the contracting officer.  This 
call, which took place after contract award, addressed changes in blade pricing and 
availability.  (Tr. 39-40; R4, tab 94 at 7 (Chromalloy’s claim discussing telephone 
call))  After award, GE required Chromalloy to purchase blades directly from GE and 
not through the part supplier Aviall (tr. 40).  In addition, GE requested that 
Chromalloy provide “seed money” to produce the blades, and notified Chromalloy of a 
price increase for the blades (id.).  According to Ms. Mackell, the contracting officer, 
Mr. Christopher Matthews, stated “we need to make this right, we need to make you 
whole on this,” and that Mr. Matthews stated that he would have stopped an order 
issued late in the contract base year had he been in the office when the order was 
issued (tr. 41, 66).   
 
Mr. Matthews testified that he never provided assurances to Chromalloy 
regarding the pricing of the blades (tr. 82).  He further testified that his 
communications with the manufacturer concerned availability and the reasons for the 
price increase in the prior year (tr. 87-88).   
 
The contract is a commercial, firm-fixed price, indefinite-delivery, indefinite-
quantity contract.  The contract consists of an informational CLIN (0001–4001), a 
priced SubCLIN (0001AA-4001AA) for remanufacture of LPT module 13/15, a priced 
SubCLIN (0001AB–4001AB) for new blades, and a data CLIN (0002–4002) (R4, 
tab 101 at 2).  The SubCLIN for new blades was priced for the base year at $5,202 per 
unit and listed as “To Be Negotiated” for all option years (R4, tab 19 at 5, 7, 10, 12, 
14).  Each SubCLIN for new blades also included the language from the RFP:  “Upon 
exercising an option, the Government reserves the right to negotiate option year unit 
pricing or provide new blades as Government Furnished Material (GFM)” (id. at 8, 10, 
12, 15).  Furthermore, the contract states in the preamble, “This is a Remanufacture 
requirement.  No Government Furnished Material (GFM) shall be provided for 
remanufature [sic] CLINs and the base year new blade subCLIN.  GFM may be 
considered, at the Government[’]s direction, for new blade subCLINs on option 
year(s).  Contractor Furnished Material (CFM) is required for all remanufacture 
described herein.”  (R4, tab 19 at 3) 
 
The contract required Chromalloy to purchase new OEM blades from 
government-approved sources.  CFM International, the OEM, published a catalog of 
various parts, including the blades, each year with prices effective on November 1 of 
the given year (R4, tab 67 at 3-5, 9; tr. 27).  Occasionally the catalog stated “QUOTE” 
instead of providing a price.  Such was the case in the catalog with prices effective on 
November 1, 2019.  (Id. at 5)  On September 12, 2019, Chromalloy received a quote 
on the blades in the amount of $5,100 each (id. at 6).  On June 23, 2020, Chromalloy 
received a quote of $5,370 per blade with a note that the price would change again on 
November 1 (id. at 7).  Chromalloy did not seek an updated price quote between 

5 
 
November 1, 2019 and submitting its bid in December 2019 (tr. 26, 48).  According to 
the catalog, the price per blade increased to $5,655 on November 1, 2020 (R4, tab 67 
at 9). 
 
The contract includes a minimum quantity for new LPT stage 1 blades of 700 
units and a maximum quantity of 50,400 units (R4, tab 19 at 4).  Each SubCLIN for 
blades includes a best estimated quantity.  The best estimated quantity for the base 
year was 7,840.  (Id. at 5)  During the base year of the contract, the government issued 
four orders for a total of 6,171 blades (R4, tab 32 at 2, tab 38 at 2, tab 43 at 2, tab 46 
at 2).  On April 17, 2021, the government exercised Option Year 1 (R4, tab 23 at 1).  
In exercising the option, the government left the price of the blades as “To Be 
Negotiated” (id. at 4).  Through a bilateral modification on December 15, 2021, the 
government exercised its right to provide the blades as GFM going forward (R4, 
tab 24 at 1). 
 
On March 21, 2021, the government issued Task Order No. FA8122-21-F-0030 
for the remanufacture of 24 modules (R4, tab 44 at 1, 3).  There were bilateral 
modifications of the task order on November 23, 2021 and December 14, 2021 to add 
218 and 155 blades, respectively (R4, tabs 45-46 at 1-2).  The modifications priced the 
blades at the contract’s base year price of $5,202 per blade.  (R4, tabs 45-46 at 4)  
Ms. Mackell testified that over the course of prior contracts, the government 
sometimes placed orders late in the contract year, but the orders were limited to work 
that could be performed over a 30 to 60 day period (tr. 43).  Mr. Matthews, the 
contracting officer, testified that it was not unusual to place a large order late in a 
contract period, citing two orders of 60 modules just prior to exercising the option for 
the next option year (tr. 91).  He indicated that the quantity included in any order was 
highly variable because it was based on estimates of future flying (tr.  90-91).   
 
In option year one of the contract, the government began providing the blades 
as government furnished material (tr. 52).  Around the time of the option year, one of 
Chromalloy’s business units accidentally ordered a number of blades.  Chromalloy 
attempted to cancel the order, but GE refused the request because the blades were 
already being manufactured.  (Tr. 64-65)   
 
On February 15, 2021, Chromalloy submitted a request for an equitable 
adjustment (REA) to the contracting officer (R4, tab 56 at 1).  The contracting officer 
denied the REA on June 17, 2021 (R4, tab 57 at 1-2).  On October 13, 2021, 
Chromalloy submitted a revised REA on substantially similar facts (R4, tab 60 at 1).  
The contracting officer denied the second REA on October 20, 2021 (R4, tab 70 
at 1-2).  Chromalloy submitted a claim dated May 26, 2022, again based upon 
substantially similar facts (R4, tab 94 at 1).  The contracting officer denied the claim 
on June 27, 2022 (R4, tab 101 at 1-2).  Chromalloy timely appealed to the Board.  The 
Board held a one-day hearing on September 4, 2024.

DECISION 
 
Chromalloy’s complaint asserts three causes of action.  First Chromalloy asserts 
that the government possessed superior knowledge regarding the availability and 
pricing of the LPT stage 1 blades which it communicated to Chromalloy, and that 
Chromalloy relied upon it in pricing its bid (compl. ¶ 20).  Chromalloy also 
characterizes this cause of action as promissory estoppel (id.).  Second, Chromalloy 
contends that it relied upon government assurances that the blades would be contractor 
furnished, and not government furnished, in purchasing a number of blades and thus, 
was left with a residual inventory of blades (compl. ¶ 21).  Chromalloy’s third cause of 
action is an alleged change to the course of dealing when the government placed a 
large order near the end of the base year of the contract, to be performed during the 
option year, at the lower base year pricing (compl. ¶¶ 22-24).  Chromalloy also 
characterizes its claim as a constructive change to the contract (compl. ¶ 26).  
Chromalloy did not submit a pre-hearing brief.  Its three-page
2 post-hearing brief fails 
to present any legal argument and does not cite any case law nor any statutes or 
regulations.  Instead, Chromalloy argues that it is entitled to relief if the Board finds 
credible the testimony of its witnesses (app. br. at 3).  
  
 I.  Chromalloy Has Not Established The Existence of Superior Knowledge 
 
Chromalloy’s first cause of action alleges that the government possessed 
superior knowledge regarding the availability and pricing of blades.  As a general rule, 
a contractor performing a fixed-price contract assumes the risk of unexpected costs.  
See, e.g., Helene Curtis Indus., Inc. v. United States, 312 F.2d 774, 777-78 (Ct. Cl. 
1963).  However, the government has an implied duty to “disclose to a contractor 
otherwise unavailable information regarding some novel matter affecting the contract 
that is vital to its performance.”  Scott Timber Co. v. United States, 692 F.3d 1365, 
1373 (Fed. Cir. 2012) (quoting Giesler v. United States, 232 F.3d 864, 876 (Fed. Cir. 
2000).  Superior knowledge generally applies when:  
 
(1) a contractor undertakes to perform without vital 
knowledge of a fact that affects performance costs or 
duration, (2) the government was aware the contractor had 
no knowledge of and had no reason to obtain such 
information, (3) any contract specification supplied misled 
the contractor or did not put it on notice to inquire, and (4) 
the government failed to provide the relevant information.   
 
 
2 Chromalloy’s brief wraps onto a fourth page only because of a 7½” bottom margin 
on page 2.   

7 
 
Hercules, Inc. v. United States, 24 F.3d 188, 196 (Fed. Cir. 1994) (quoting American 
Ship Bldg. Co. v. United States, 654 F.2d 75, 79 (Ct. Cl. 1981)).   
 
As an initial matter, we find that Chromalloy has not demonstrated, or even 
properly alleged, that the government possessed superior knowledge regarding future 
pricing of the blades.  Expectations or judgment regarding future events, rather than 
existing facts do not support a superior knowledge claim.  See, e.g., ACC Constr., Co., 
ASBCA Nos. 62265, 62937, 22-1 BCA ¶ 38,194 at 185,481; aff’d, No. 2023-1372, 
2024 WL 2064620 (Fed. Cir. May 9, 2024).  For the government to possess superior 
knowledge of future blade prices, Chromalloy would need to establish that the 
manufacturer or distributor shared with the government its pricing plans for the blades, 
not simply that it expected prices to remain stable.  In fact, Chromalloy’s claim asserts 
that the government did not intentionally mislead Chromalloy but rather that it might 
have passed on bad information that it received from the blade manufacturer or 
distributor (R4, tab 94 at 3-4).  Thus, it is not clear that Chromalloy is even alleging 
that the government possessed superior knowledge. 
 
Moreover, Chromalloy has not shown that it was misled by a contract 
specification.  Instead, the hearing testimony of Chromalloy’s witnesses established 
that Chromalloy was aware of availability issues and price increases for the blades 
(tr. 14) and that Chromalloy had a relationship with the distributor, Aviall (tr. 34).  
Chromalloy further knew that the blade prices typically increased in November of each 
year, (tr. 27) yet failed to seek updated information before submitting its bid (tr. 26, 
48).   
 
At best, Chromalloy cites to an alleged promise made by the contracting officer 
on June 17, 2020 (tr. 39-40; R4, tab 94 at 7).  Even if we were to credit the testimony 
of Chromalloy’s witness over the contracting officer’s denial that he made such a 
statement (tr. 82), the alleged statement was made after Chromalloy made its bid and 
thus could not have been superior knowledge that would have effected performance 
cost or duration. 
  
To the extent Chromalloy is asserting a claim for promissory estoppel (compl. 
¶ 19) we deny the claim for two reasons.  First, as noted above, Chromalloy is relying 
upon a statement allegedly made after it submitted its bid, thus, Chromalloy cannot 
establish detrimental reliance upon the statement.  Second, and more importantly, the 
Board lacks jurisdiction to entertain claims for promissory estoppel.  See, e.g., Selevive 
Group, LC, ASBCA Nos. 63292, 63293, 22-1 BCA ¶ 38,220 at 185,638.  We deny 
Chromalloy’s claim regarding blade pricing.  
  

8 
 
II.  The Contract Permitted the Government to Provide Blades as GFM 
 
Chromalloy contends that the government provided assurances that the blades 
would be contractor furnished material and that it was damaged financially when the 
government decided to provide the blades as government furnished material, leaving it 
with a stock of residual material.  The contract explicitly provides that the government 
may supply the blades as GFM (R4, tab 19 at 3).  Chromalloy’s witnesses did not 
testify as to any assurances provided by the government that the blades would be 
contractor furnished.  In fact, Ms. Mackell testified that the residual inventory blades 
were ordered accidentally by one of Chromalloy’s business units.  Chromalloy 
attempted to cancel the order, but GE refused the request because the blades were 
already being manufactured (tr. 64-65).  We deny the appeal with regard to 
Chromalloy’s claim regarding the change to GFM.    
 
III.  The Government Has Not Violated A Prior Course of Dealings 
 
Chromalloy asserts that the government violated a prior course of dealings in its 
submission of a large order at the end of the base contract period.  According to 
Chromalloy, the order should have been submitted during the first option period, and 
priced according to the higher option period price.  Our precedent recognizes a course 
of dealing as “a sequence of previous conduct between the parties to an agreement 
which is fairly to be regarded as establishing a common basis of understanding for 
interpreting their expressions and other conduct.”  Tech. Sys., Inc., ASBCA No. 59577, 
17-1 BCA ¶ 36,631 at 178,388 (quoting RESTATEMENT (SECOND) OF 
CONTRACTS § 223 (1981)).  “[A] course of dealing can supply an enforceable term 
to a contract . . . provided that the conduct which identifies that course of dealing can 
reasonably be construed as indicative of the parties’ intentions – a reflection of their 
joint or common understanding.”  Id. (quoting Sperry Flight Systems v. United States, 
548 F.2d 915, 923 (Ct. Cl. 1977)).  
 
Here, Ms. Mackell testified that the government often issued task orders late in 
the contracting period, but for work that could be performed within 30 to 60 days 
(tr. 43).  Ms. Mackell testified that the contracting officer, Mr. Matthews told her that 
he would have stopped the order had he been in the office when the order was issued 
(tr. 66).  The contracting officer disagreed with Chromalloy’s characterization of the 
order, indicating that the orders were highly variable because they were based on 
expected flying hours and that the government had frequently made even larger orders 
late in the contract period (tr. 90-91).  Neither party asked Mr. Matthews about his 
alleged statement that he would have blocked the order had he been in the office.  
Based upon the evidence before us, we hold that Chromalloy has not demonstrated by 
preponderant evidence that there was a sequence of previous conduct indicating a joint 
or common understanding of the parties for interpreting the contract.  At best, 
Chromalloy is speculating as to the government’s reasons for placing orders of 

9 
 
different sizes at different times during the contract.  Speculation cannot “reasonably 
be construed as indicative of the parties’ intentions [or] their joint and common 
understanding.”  Tech. Sys., 17-1 BCA ¶ 36,631 at 178,388 (quoting Sperry Flight 
Systems, 548 F.2d at 923). 
 
The Federal Circuit recently issued an opinion addressing the pricing of work 
ordered in one contract year, but performed in a later contract year.  WSP USA Sols. 
Inc. v. Army, No. 2023-1256, 2025 WL 573242 (Fed. Cir. Feb. 21, 2025).  In WSP the 
court indicated that the entire contract, including modifications, should be reviewed in 
interpreting the contract.  Id. at *7.  Here, the two modifications to Task Order 
No. FA8122-21-F-0030 were both issued bilaterally.  By agreeing to a substituted 
performance in each modification, Chromalloy waived any potential claim regarding 
the timing of the purchase of additional blades.  See, e.g., Amentum Services, Inc. 
F/K/A AECOM Management Services, Inc. ASBCA Nos. 62835 et al., 23-1 BCA ¶ 
38,453 at 186,891. 
 
IV.  Chromalloy Has Not Established A Constructive Change 
Chromalloy’s complaint additionally asserts that its claims addressed above 
were constructive changes to the contract (compl ¶ 26).  To the extent Chromalloy is 
raising a constructive change claim, such a claim would require evidence that 
Chromalloy 1) performed work beyond the requirements of the contract; and 2) that 
the additional work was ordered by the government.  See, e.g., Bell/Heery v. United 
States, 739 F.3d 1324, 1335 (Fed. Cir. 2014).  However, Chromalloy has not alleged 
that it performed any work not required by the contract.   
 
Chromalloy first alleges that the government had superior knowledge of blade 
pricing.  Here Chromalloy complains of pricing, not that it was required to perform 
extra work.  Chromalloy’s second basis is that the government’s switch to 
government-furnished material for the blades left it with excess inventory.  However, 
the contract explicitly provided that the blades could be GFM, and, thus, Chromalloy 
has not alleged additional work.  Chromalloy’s third claim of a breach of the course of 
dealings again does not allege extra work.  Rather, Chromalloy is again complaining 
about the pricing of the blades, that is, whether the work should have been priced at 
the base year or option year prices.  Chromalloy does not allege that it was required to 
perform work not required by the contract and we deny Chromalloy’s constructive 
change allegations.

For the reasons stated above, Chromalloy’s appeal is denied.
