Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–600, 

–700, –700C, –800, –900, and –900ER 

series airplanes. This AD was prompted 

by a report of an in-service occurrence 

of total loss of boost pump pressure of 

the fuel feed system, followed by loss of 

fuel system suction feed capability on 

one engine, and in-flight shutdown of 

the engine. This AD requires repetitive 

operational tests of the engine fuel 

suction feed of the fuel system, and 

other related testing and corrective 

action if necessary. We are issuing this 

AD to detect and correct loss of the 

engine fuel suction feed capability of 

the fuel system, which in the event of 

total loss of the fuel boost pumps could 

result in dual engine flameout, inability 

to restart the engines, and consequent 

forced landing of the airplane. 

DATES: This AD is effective October 1, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of October 1, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (SNPRM) to 

amend 14 CFR part 39 to include an 

airworthiness directive (AD) that would 

apply to the specified products. The 

SNPRM published in the Federal 

Register on June 25, 2012 (77 FR 37831). 

We preceded the SNPRM with a notice 

of proposed rulemaking (NPRM), which 

published in the Federal Register on 

June 6, 2008 (73 FR 32255). The NPRM 

proposed to require repetitive 

operational tests of the engine fuel 

suction feed of the fuel system, and 

other related testing if necessary. The 

SNPRM proposed to require repetitive 

operational tests of the engine fuel 

suction feed of the fuel system, and 

other related testing and corrective 

action if necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 37831, 

June 25, 2012) and the FAA’s response 

to each comment. 

Requests To Change Certain Methods of 

Compliance 

Boeing asked that we change the next 

to last sentence in paragraph (g) of the 

SNPRM (77 FR 37831, June 25, 2012), 

which specifies ‘‘. . . using a method 

approved in accordance with the 

procedures specified in paragraph (h) of 

this AD’’ to read ‘‘If the test is not 

considered successful, as specified in 

AWL No. 28–AWL–101, before further 

flight, perform all related testing and 

corrective actions, and repeat the 

operational test specified in AWL No. 

28–AWL–101.’’ Boeing noted that 

paragraph (h) of the SNPRM (paragraph 

(i) of this final rule) does not provide 

testing and corrective actions for a failed 

test, and FAA approval of action taken 


pmangrum on DSK3VPTVN1PROD with RULES
Federal Register / Vol. 78, No. 166 / Tuesday, August 27, 2013 / Rules and Regulations 52839 

to address a failed test could result in 

an excessive burden to operators and 

could cause unnecessary grounding of 

airplanes while coordinating planned 

actions with the FAA. 

Delta Airlines (DAL) requested that 

we include an existing fault isolation 

manual (FIM) procedure as an approved 

method for resolving unsuccessful 

testing. 

American Airlines (AAL) stated that 

paragraph (g) of the SNPRM (77 FR 

37831, June 25, 2012) specifies that the 

corrective action for findings from the 

operational test is to perform all related 

testing and corrective actions in 

accordance with the procedures 

specified in paragraph (h) of the SNPRM 

(paragraph (i) of this final rule). AAL 

added that paragraph (h) of the SNPRM 

provides information on obtaining 

AMOCs, and asked for clarification on 

that approval. 

We agree to revise the requirements 

and methods of compliance specified in 

paragraph (g) of this AD. In paragraph 

(g)(1)(i) of this final rule, we have 

retained the requirement for performing 

all related testing and corrective actions 

using a method approved in accordance 

with the procedures specified in 

paragraph (i) of this AD. As requested 

by Boeing, we have added new 

paragraph (g)(1)(ii) to this final rule to 

perform all related testing and 

corrective actions, and to repeat the 

operational test specified in AWL No. 

28–AWL–101. The actions specified in 

paragraph (g)(1)(ii) do not require 

submitting requests to the FAA for 

approval of a method of compliance. 

Therefore, including an existing FIM 

procedure in the AD as an approved 

method becomes unnecessary for 

resolving unsuccessful testing since 

operators may use any method of 

compliance to resolve unsuccessful 

testing, provided the operational test is 

repeated. 

In addition, we have reviewed Boeing 

737–600/700/700C/800/900/900ER 

Maintenance Planning Data (MPD) 

Document, Section 9, Airworthiness 

Limitations (AWLs) and Certification 

Maintenance Requirements (CMRs), 

D626A001–CMR, Revision August 2012, 

which includes AWL No. 28–AWL–101. 

As an option for the repetitive 

operational tests (specified in paragraph 

(g)(1) of this AD), we have specified 

incorporating AWL No. 28–AWL–101 

into the maintenance program 

(paragraph (g)(2) of this AD). 

Compliance with these actions is 

required by section 91.403(c) of the 

Federal Aviation Regulations (14 CFR 

91.403(c)). For airplanes that have been 

previously modified, altered, or repaired 

in the areas addressed by these 

inspections, the operator may not be 

able to accomplish the inspections 

described in the revisions. In this 

situation, to comply with 14 CFR 

91.403(c), the operator must request 

approval for an AMOC according to the 

procedures specified in paragraph (i) of 

this AD. The request should include a 

description of changes to the required 

actions that will ensure the continued 

operational safety of the airplane. 

Requests To Allow Task Card 

Instructions as an AMOC; Clarify 

Airplane Maintenance Manual (AMM) 

Task 

DAL suggested that the SNPRM (77 

FR 37831, June 25, 2012) include 

compliance with the engine fuel suction 

feed test using Boeing 737–600/700/800 

Task Card 28–050–00–01 as an AMOC. 

DAL stated that this task card complies 

with the requirements of AWL No. 28– 

AWL–101, which is specified in 

paragraph (g) of the SNPRM. AAL asked 

for clarification that Boeing AMM Task 

28–22–00–710–802, Engine Fuel 

Suction Feed—Operational Test, can be 

used as an AMOC. 

Although we agree that the task card 

contains adequate instructions to 

perform the test, we do not agree with 

identifying the task card information 

within the instructions for the mandated 

action. For clarification, general 

maintenance instructions are identified 

within the AWL for guidance, which 

means that if the operator already has an 

accepted alternative procedure, that 

procedure may be used. The 

maintenance program with the task 

cards incorporated is an acceptable 

alternative procedure. We have made no 

change to the AD in this regard. 

Request To Increase Repetitive Interval 

for Operational Tests 

AAL asked that we increase the 

repetitive operational test interval in the 

SNPRM (77 FR 37831, June 25, 2012) 

from 7,500 to 10,000 flight hours. AAL 

provided a risk-based assessment for 

extending the intervals based on its 

experience. AAL stated within its 

assessment that the loss of suction feed 

capability would remain remote with 

the extended testing interval. 

We do not agree with the request to 

increase the repetitive operational test 

interval. The service data of transport 

category airplanes indicates that multiengine flameouts generally result from a 

common cause such as fuel 

mismanagement, crew action that 

inadvertently shuts off the fuel supply 

to the engines, exposure to common 

environmental conditions, or engine 

deterioration occurring on all engines of 

the same type—not solely the failure of 

multiple fuel boost pumps. This risk 

assessment is based on the results of 

maintenance findings of one operator’s 

fleet, and does not support increasing 

the repetitive interval. The current 

interval is based on an overall fleet 

assessment by the original equipment 

manufacturer. However, affected 

operators may request approval of an 

AMOC for an increase of the repetitive 

operational test interval under the 

provisions of paragraph (i) of this AD by 

submitting data substantiating that the 

change would provide an acceptable 

level of safety. We have made no change 

to the AD in this regard. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We also determined that these changes 

will not increase the economic burden 

on any operator or increase the scope of 

this AD. 

Costs of Compliance 

We estimate that this AD affects 1,080 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Cost per 

product 

Cost on U.S. 

operators 

Operational Test/Revision ............................................ 1 work-hour × $85 per hour = $85 ............................... $85 $91,800 

We have received no definitive data 

that would enable us to provide a cost 

estimate for the on-condition actions or the optional terminating action 

specified in this AD.

52840 Federal Register / Vol. 78, No. 166 / Tuesday, August 27, 2013 / Rules and Regulations 

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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

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

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation 

in Alaska, and 

(4) Will not have a significant 

economic impact, positive or negative,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

airworthiness directive (AD) for all 

Lockheed Martin Corporation/Lockheed 

Martin Aeronautics Company Model L– 

1011 series airplanes. AD 2005–15–01 

required repetitive inspections to detect 

corrosion or fatigue cracking of certain 

structural elements of the airplane, 

corrective actions if necessary, and 

incorporation of certain structural 

modifications. This new AD reduces 

certain compliance times for the initial 

inspection and the repetitive inspection 

interval for certain airplanes. This AD 

was prompted by reports of small cracks 

in additional areas outside those 

addressed in AD 2005–15–01, prior to 

the inspection threshold required by the 

AD 2005–15–01. We are issuing this AD 

to prevent corrosion or fatigue cracking 

of certain structural elements, which 

could result in reduced structural 

integrity of the airplane. 

DATES: This AD is effective October 1, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of October 1, 2013. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2005–15–01, 

Amendment 39–14190 (70 FR 42262, 

July 22, 2005). AD 2005–15–01 applied 

to the specified products. The NPRM 

published in the Federal Register on 

October 16, 2012 (77 FR 63275). The 

NPRM proposed to continue to require 

repetitive inspections to detect 

corrosion or fatigue cracking of certain 

structural elements of the airplane, 

corrective actions if necessary, and 

incorporation of certain structural 

modifications. The NPRM also proposed 

to require reducing certain compliance 

times for the initial inspection and the 

repetitive inspection interval for certain 

airplanes. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal (77 FR 63275, 

October 16, 2012) and the FAA’s 

response to each comment. 

Request To Update Certain Address 

Information 

Lockheed Martin Corporation/

Lockheed Martin Aeronautics Company 

requested that we revise the NPRM (77 

FR 63275, October 16, 2012) to update 

its address information. 

We agree to update the address 

information in this final rule. We have 

included this updated information in 

the ADDRESSES section and paragraph 

(n)(5) of this AD. 

Additional Change Made to This AD 

We have revised paragraph (g)(10) of 

this AD (in table 1 to paragraph (g) of 

this AD) to include paragraph identifiers 

for paragraphs (g)(10)(i) and (g)(10)(ii) of 

this AD. This change is for formatting 

purposes only. 

Conclusion 

We reviewed the relevant data, 

considered the comment received, and 

determined that air safety and the 

public interest require adopting this AD 

with the change described previously— 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

63275, October 16, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 63275, 

October 16, 2012). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD affects 26 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD:
