Unsafe condition
This AD was prompted by a report that a right-hand outboard elevator was received and installed without balance weights. The FAA is issuing this AD to address left-hand and right-hand outboard elevators delivered without balance weights. The unsafe condition, if not addressed, could result in abnormal vibration, buffeting, flutter, or oscillation that could result in loss of continued safe flight and landing. Further, outboard elevators without balance weights could result in personal injury to maintenance personnel during installation or removal of the outboard elevators.
Affected ADs
None.
