Summary
This document proposes to supersede AD 92-27-10, which currently requires inspecting the pilot and copilot chairs to ensure that the locking pins will fully engage in the seat tracks on certain Beech Aircraft Corporation (Beech) 90, 99, 100, 200, and 1900 series airplanes, and modifying any chair where any locking pin fails to fully engage or is misaligned. Reports of pilot and copilot chair locking pin malfunctions prompted AD 92-27-10. Since issuance of that AD, the Federal Aviation Administration (FAA) has determined that additional airplanes should be affected by the pilot and copilot chair locking pins inspection and modification (if required), and that the inspection should be accomplished in accordance with revised procedures. The proposed action would retain the inspection and modification requirements of AD 92-27-10; incorporate additional airplanes into the applicability over that included in AD 92-27-10; and require the inspection in accordance with revised service information. The actions specified by the proposed AD are intended to prevent inadvertent movement of the pilot or copilot chair, which could result in loss of control of the airplane if it occurs during a critical flight maneuver.
