Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. Subtitle VII: 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701: 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would not have a 

substantial direct effect on the States, on 

the relationship between the national 

Government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

the DOT Regulatory Policies and 

Procedures (44 FR 11034, February 26, 

1979), 

(3) Will not affect intrastate aviation 

in Alaska to the extent that it justifies 

making a regulatory distinction, and 

(4) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:

America Code 83, Accessory Gearboxes. 

(e) Unsafe Condition 

This AD was prompted by reports of the 

failure of the RDS on CFM CFM56–5B

compliance times specified, unless already 

done. 

Within 6 months after the effective date of 

this AD, remove the RDS assembly, part

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede

Federal Register / Vol. 81, No. 211 / Tuesday, November 1, 2016 / Proposed Rules 75763 

10 that applies to all Rolls-Royce plc 

(RR) RB211 Trent 768–60, 772–60, and 

772B–60 turbofan engines. AD 2014– 

16–10 requires initial and repetitive 

ultrasonic inspections (UIs) of the 

affected low-pressure (LP) compressor 

blades. Since we issued AD 2014–16– 

10, RR issued revised service 

information to reduce the inspection 

threshold. This proposed AD would 

retain the UIs in AD 2014–16–10 while 

applying the revised inspection 

threshold. We are proposing this AD to 

prevent LP compressor blade airfoil 

separations, damage to the engine, and 

damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by December 16, 

2016. 

ADDRESSES: You may send comments,

Discussion 

On August 1, 2014, we issued AD 

2014–16–10, Amendment 39–17934 (79 

FR 48961, August 19, 2014), (‘‘AD 2014– 

16–10’’) for all RR RB211 Trent 768–60, 

772–60, and 772B–60 turbofan engines. 

AD 2014–16–10 requires initial and 

repetitive UIs of the affected LP 

compressor blades. AD 2014–16–10 

resulted from LP compressor blade 

partial airfoil blade release events. We 

issued AD 2014–16–10 to prevent LP 

compressor blade airfoil separations, 

damage to the engine, and damage to the 

airplane. 

Actions Since AD 2014–16–10 Was 

Issued 

Since we issued AD 2014–16–10, RR 

issued Alert Non-Modification Service 

Bulletin (NMSB) RB.211–72–AH465, 

Revision 2, dated May 11, 2016. The 

Alert NMSB reduced the inspection 

threshold for UI of the LP compressor 

blades. Also since we issued AD 2014– 

16–10, the European Aviation Safety 

Agency (EASA) issued a correction to 

AD 2016–0141, dated July 20, 2016, 

requiring the revised inspection 

threshold. 

Related Service Information Under 1 

CFR Part 51 

RR has issued Alert NMSB RB.211– 

72–AH465, Revision 2, dated May 11, 

2016. The NMSB describes procedures 

for performing a UI of the LP 

compressor blades. This service 

information is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by the means identified 

in the ADDRESSES section. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

initial and repetitive UIs of the affected 

LP compressor blades. This proposed 

AD would require conducting the UIs at 

a reduced inspection threshold. 

Costs of Compliance 

We estimate that this proposed AD 

affects 56 engines installed on airplanes 

of U.S. registry. We also estimate that it 

would take about 40 hours per engine to 

comply with this proposed AD. The 

average labor rate is $85 per hour. Based 

on these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $190,400. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

Section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701, 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We have determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that the proposed regulation:

(d) Unsafe Condition 

This AD was prompted by LP compressor 

blade partial airfoil release events. We are 

issuing this AD to prevent LP compressor 

blade airfoil separations, damage to the 

engine, and damage to the airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) Ultrasonic Inspection (UI) of LP 

Compressor Blade 

(i) After the effective date of this AD, for 

LP compressor blades that have accumulated 

less than 1,800 cycles since new (CSN) or 

cycles since last inspection (CSLI), perform a 

UI of each LP compressor blade before the 

blade exceeds 2,400 CSN or CSLI. Repeat the 

UI of the blade before exceeding 2,400 CSLI. 

(ii) For any LP compressor blade that 

exceeds 1,800 CSN on the effective date of 

this AD, inspect the blade before exceeding 

600 flight cycles after the effective date of 

this AD or before exceeding 3,600 CSN, 

whichever occurs first. Thereafter, perform 

the repetitive inspections before exceeding 

2,400 CSLI. 

(iii) For any blade that exceeds 2,200 CSLI 

on September 23, 2014 (the effective date of 

AD 2014–16–10), inspect the blade before 

exceeding 3,000 CSLI or before further flight, 

whichever occurs later. Thereafter, perform 

the repetitive inspections before exceeding 

2,400 CSLI. 

(iv) Use paragraph 3, excluding 

subparagraphs 3.C.(2)(b), 3.D.(2) and 3.G, of 

RR Alert Non-Modification Service Bulletin

CSLI is eligible for installation if the blade 

has passed the UI required by this AD. 

(ii) Reserved. 

(f) Credit for Previous Actions 

You may take credit for the UI required by 

paragraph (e) of this AD, if you performed the 

UI before the effective date of this AD using
