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.

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.

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

[[Page 23740]]

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:

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.
