Models named: 777-200, 777-200LR, 777-300, 777-300ER, 777F series. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to all The Boeing Company Model 777-200, 777-200LR, 777-300, 777-300ER, and 777F series airplanes, certificated in any category.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

For airplanes on which the original airworthiness certificate or the original export certificate of airworthiness was issued on or before the effective date of this AD: Within 36 months after the effective date of this AD, identify the serial number and marking of the MLG aft trunnion pins, in accordance with Part 1 of the Accomplishment Instructions of Boeing Alert Service Bulletin 777-32A0103, Revision 1, dated December 10, 2015.

Unsafe condition

This 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. We are issuing 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.

Affected ADs

None.
