AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 777 

airplanes. This AD was prompted by 

reports of fire and smoke at the engine 

aft pylon area resulting from fuel 

leakage caused by a damaged O-ring in 

the fuel coupling attached to the wing 

front spar. This AD requires applying 

sealant to fill the gap between the lower 

wing panels adjacent to the strut aft 

vapor barrier. We are issuing this AD to 

prevent fire and smoke at the engine aft 

pylon area in the event of a fuel leak, 

which could cause personal injury 

during ground operations. A fire 

spreading back and up to the aft fairing 

pylon can result in an uncontrolled fire 

in the strut and ignite the fuel tank. 

DATES: This AD is effective April 22, 

2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of April 22, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain The Boeing Company 

Model 777 airplanes. The NPRM 

published in the Federal Register on 

July 9, 2015 (80 FR 39392). The NPRM 

was prompted by reports of fire and 

smoke at the engine aft pylon area 

resulting from fuel leakage caused by a 

damaged O ring in the fuel coupling 

attached to the wing front spar. The fuel 

was captured by the fuel coupling 

rubber boot and was discharged into the 

flammable fluid leakage zone of the 

strut-to-wing cavity, as intended. 

However, the fuel did not follow its 

intended drain paths into the aft strut 

and lower wing panel drains, but 

instead followed an unintended drain 

path through an unsealed gap between 

the lower wing panels above the strut aft 

vapor barrier. The leaking fuel then 

followed gaps and seams in the aft 

fairing structure to the outside of the 

strut fairing side panels, ignited after 


asabaliauskas on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 81, No. 53 / Friday, March 18, 2016 / Rules and Regulations 14699 

contact with the hot engine exhaust heat 

shield, and caused a fire and smoke. We 

are issuing this AD to prevent fire and 

smoke at the engine aft pylon area in the 

event of a fuel leak, which could cause 

personal injury during ground 

operations. A fire spreading back and up 

to the aft fairing pylon can result in an 

uncontrolled fire in the strut and ignite 

the fuel tank. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comments received. 

Boeing concurred with the NPRM (80 

FR 39392, dated July 9, 2015), and 

FedEx had no technical objection. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

as proposed—except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (80 FR 

39392, dated July 9, 2015) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (80 FR 39392, 

dated July 9, 2015). 

Related Service Information Under 

1 CFR Part 51 

We have reviewed Boeing Special 

Attention Service Bulletin 777–54– 

0035, dated October 30, 2014. The 

service information describes 

procedures for applying sealant to fill 

the gap between wing panels. 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. 

Costs of Compliance 

We estimate that this AD affects 196 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Sealant application ................. 3 work-hours × $85 per hour = $255 ..................................... $0 $255 $49,980 

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, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to the specified products. The 

NPRM was published in the Federal 

Register on November 10, 2015 (80 FR 

69623). The NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

There have been in-service incidents 

involving corrosion and perforation of the 

two-ply Cu-Be bellows in Woodward Fuel 

Control Units (FCU) fitted to PT6A–60, –65 

and –67 series engines. In certain instances, 

associated bellows leakage has resulted in 

loss of engine power, in-flight shutdowns 

(IFSD) and even accidents. Engines installed
