Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 747–8 

series airplanes. This proposed AD was 

prompted by a report of improperly 

installed outboard stowage bin modules 

in the passenger compartment found 

during maintenance. Further 

investigation revealed that certain 

attachment bracket bushings were 

missing or had moved out of the holes. 

This proposed AD would require 

installing a spacer on the end of each 

quick-release pin that attaches the 

outboard stowage bin module to the 

lateral support tie rods of the main deck 

passenger compartment. We are 

proposing this AD to prevent 

detachment of the quick-release pin, 

which could result in separation of the 

lateral support tie rod and subsequent 

detachment of the module and 

consequent injuries to passengers or 

flightcrew. 

DATES: We must receive comments on 

this proposed AD by June 15, 2015. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

We have received a report of 

improperly installed outboard stowage 

bin modules in the passenger 

compartment found during 

maintenance. Further investigation 

revealed that certain attachment bracket 

bushings of the outboard stowage bin 

module were missing or had moved out 

of the holes, and pins were installed 

incorrectly. These bushings were 

designed to prevent disengagement of 

the quick release pins; however, 

migration of the bushings deters this. It 

was determined that the interference fit 

of the bushings in the attachment 

brackets was incorrect. Subsequently, 

installation of the quick release pins 

during production has caused bushings 

to migrate or detach. This condition, if 

not corrected, could result in separation 

of the lateral support tie rod, 

detachment of the outboard stowage bin 

module, and consequent injuries to 

passengers or flightcrew. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Boeing Special 

Attention Service Bulletin 747–25– 

3649, dated July 24, 2014. The service 

information describes procedures for 

installing a spacer on the end of each 

quick-release pin that attaches the 

outboard stowage bin module to the 

lateral support tie rods of the main deck 

passenger compartment. Refer to this 

service information for information on 

the procedures and compliance times. 

This service information is reasonably 

available; see ADDRESSES for ways to 

access this service information. 

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 

accomplishing the actions specified in 

the service information identified 

previously. 

Explanation of ‘‘RC’’ Steps in Service 

Information 

The FAA worked in conjunction with 

industry, under the Airworthiness 

Directives Implementation Aviation 

Rulemaking Committee, to enhance the 

AD system. One enhancement was a 

mstockstill on DSK4VPTVN1PROD with PROPOSALS

23740 Federal Register / Vol. 80, No. 82 / Wednesday, April 29, 2015 / Proposed Rules 

new process for annotating which steps 

in the service information are required 

for compliance with an AD. 

Differentiating these steps from other 

tasks in the service information is 

expected to improve an owner’s/

operator’s understanding of crucial AD 

requirements and help provide 

consistent judgment in AD compliance. 

The actions specified in the service 

information described previously 

include steps that are labeled as RC 

(required for compliance) because these 

steps have a direct effect on detecting, 

preventing, resolving, or eliminating an 

identified unsafe condition. 

Steps that are identified as RC in any 

service information must be done to 

comply with the proposed AD. 

However, steps that are not identified as 

RC are recommended. Those steps that 

are not identified as RC may be deviated 

from using accepted methods in 

accordance with the operator’s 

maintenance or inspection program 

without obtaining approval of an 

alternative method of compliance 

(AMOC), provided the steps identified 

as RC can be done and the airplane can 

be put back in a serviceable condition. 

Any substitutions or changes to steps 

identified as RC will require approval of 

an AMOC. 

Costs of Compliance 

We estimate that this proposed AD 

affects 2 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Spacer installations .... Up to 12 work-hours X $85 per hour = Up to $1,020 ............ $0 $85 per spacer Up to $2,040. 

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, 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.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2014– 

0250, dated November 19, 2014 

(referred to hereinafter as ‘‘the MCAI’’), 

to correct an unsafe condition for the 

specified products. The MCAI states: 

There were a number of pre-MOD/SB 72– 

7730 High Pressure Turbine (HPT) blade 

failures, with some occurring within a 

relatively short time. Engineering analysis 

carried out by RR on those occurrences 

indicates that certain pre-MOD/SB 72–7730 

blades, Part Number (P/N) UL32958 and P/ 

N UL21691 (hereafter referred to as ‘affected 

HPT blade’), with an accumulated life of 

6500 flight hours (FH) since new or more, 

have an increased risk of in-service failure. 

This condition, if not corrected, could lead 

to HPT blade failure, release of debris and 

consequent (partial or complete) loss of 

engine power, possibly resulting in reduced 

control of the aeroplane. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

0095. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of the United 

Kingdom, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information provided by EASA and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. This 

proposed AD would require removal of 

the affected HPT blades.
