Applicability*9
This AD applies to The Boeing Company Model 777-200LR and -300ER series airplanes, certificated in any category, identified in Boeing Alert Service Bulletin 777-27A0109, dated December 1, 2011.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 48 months after the effective date of this AD, review the airplane's maintenance records for each rudder power control unit (PCU) to identify the condition of its related reaction link assembly, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 777-27A0109, dated December 1, 2011.
Unsafe condition
This AD was prompted by a report of an abnormal airframe vibration in the aft fuselage during flight. We are issuing this AD to prevent excessive freeplay in the rudder control surface, which could cause rudder vibration, and result in structural damage severe enough to prevent continued safe flight and landing.
Affected ADs
None.
