Boeing Model 777-200, -200LR, -300, and -300ER Series Airplanes
Superseded. A later AD replaced this one: AD 2013-08-02. Comply with the one in force.
This AD applies to all Boeing Model 777-200, -200LR, -300, and -300ER series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires doing initial and repetitive inspections for cracking of the elevator actuator fittings, and replacing any cracked fitting with a new fitting. This AD results from a report that a cracked left elevator actuator fitting was found on a Model 777 airplane. We are issuing this AD to detect and correct a cracked actuator fitting, which could detach from the elevator and lead to an unrestrained elevator and an unacceptable flutter condition, which could result in loss of airplane control.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable time specified in paragraph 1.E. “Compliance” of Boeing Alert Service Bulletin 777-55A0015, dated April 19, 2007, do an initial dye penetrant or high-frequency eddy current (HFEC) inspection for cracking of the elevator actuator fittings, and, thereafter, do repetitive dye penetrant, HFEC, or detailed inspections at the applicable times specified in paragraph 1.E. “Compliance.” Before further flight, replace any fitting found to be cracked during any inspection required by this AD with a new fitting having the same part number, or an optional part number as identified in the service bulletin. Thereafter, do initial and repetitive inspections of the replacement fitting as described in paragraph 1.E. of the service bulletin. Do all inspections and actions described in this paragraph in accordance with the Accomplishment Instructions of the service bulletin; except, where the service bulletin specifies a compliance time after the date on the service bulletin, this AD requires compliance within the specified compliance time after the effective date of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
