We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 777 airplanes. This proposed AD was prompted by a report of an incident involving a landing in which the pilots needed to input corrections due to airplane yaw and roll to the right; the main landing gear (MLG) aft trunnion pin was later found to be fractured. This proposed AD would require identification and replacement of certain MLG aft trunnion pins. We are proposing this AD to prevent a fractured MLG aft trunnion pin, which could result in collapse of the MLG and consequent loss of control of the airplane during landing.

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 all 
The Boeing Company Model 777 airplanes. This proposed AD was prompted 
by a report of an incident involving a landing in which the pilots 
needed to input corrections due to airplane yaw and roll to the right; 
the main landing gear (MLG) aft trunnion pin was later found to be 
fractured. This proposed AD would require identification and 
replacement of certain MLG aft trunnion pins. We are proposing this AD 
to prevent a fractured MLG aft trunnion pin, which could result in 
collapse of the MLG and consequent loss of control of the airplane 
during landing.

Discussion

    We have received a report of an incident involving a landing in 
which the pilots needed to input corrections due to airplane yaw and 
roll to the right; the MLG aft trunnion pin was later found to be 
fractured. Other damage included minor damage to the gear beam and 
trunnion door panel and a broken tie rod. Analysis of the fractured pin 
showed that the crack started from an area of heat damage introduced 
during manufacturing. A review of gear overhaul records indicated that 
other pins manufactured by the same supplier had similar signs of heat 
damage, suspected to have been caused by abusive chrome grinding. This 
evidence suggests that the heat damage occurred during manufacturing, 
so it is possible that other airplanes have aft trunnion pins with 
similar heat damage. This condition, if not corrected, could result in 
collapse of the MLG and consequent loss of control of the airplane 
during landing.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 777-32A0103, Revision 1, 
dated December 10, 2015. The service information describes procedures 
for identifying and replacing certain MLG aft trunnion pins. 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 accomplishing the actions specified 
in the service information described previously.

[[Page 8165]]

Differences Between This Proposed AD and the Service Information

    Boeing Alert Service Bulletin 777-32A0103, Revision 1, dated 
December 10, 2015, limits the effectivity to Model 777 airplanes, line 
numbers 1 through 1330 inclusive. However, this proposed AD does not 
propose to limit the applicability to those line numbers. The 
applicability of this proposed AD includes all The Boeing Company Model 
777-200, 777-200LR, 777-300, 777-300ER, and 777F series airplanes. 
Because the affected trunnion pins are rotable parts, we have 
determined that these parts could later be installed on airplanes that 
were initially delivered with acceptable pins, thereby subjecting those 
airplanes to the unsafe condition. This difference has been coordinated 
with Boeing.

Explanation of ``RC'' Steps in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directive Implementation Aviation Rulemaking Committee 
(ARC), to enhance the AD system. One enhancement was a 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 steps identified as Required for 
Compliance (RC) in any service information identified previously have a 
direct effect on detecting, preventing, resolving, or eliminating an 
identified unsafe condition.
    For service information that contains steps that are labeled as RC, 
the following provisions apply: (1) The steps labeled as RC, including 
substeps under an RC step and any figures identified in an RC step, 
must be done to comply with the AD, and an AMOC is required for any 
deviations to RC steps, including substeps and identified figures; and 
(2) steps not labeled as RC may be deviated from using accepted methods 
in accordance with the operator's maintenance or inspection program 
without obtaining approval of an AMOC, provided the RC steps, including 
substeps and identified figures, can still be done as specified, and 
the airplane can be put back in an airworthy condition.

Costs of Compliance

    We estimate that this proposed AD affects 123 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.

                                       hour = $170.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft that might need 
this repair:

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.
