The FAA is adopting a new airworthiness directive (AD) for Sicma Aero Seat third occupant seat assemblies, 133 series. This AD requires visually inspecting the installation of the two headrest bushings and installing Mecanindus pins to secure the bushings. This AD results from Sicma's determination that missing or incorrectly secured bushings could loosen and cause disengagement of the headrest from the seat during a high-energy stop of the airplane, possibly injuring the seat occupant. We are issuing this AD to prevent disengagement of the headrest from the seat during a high-energy stop of the airplane that could injure the seat occupant.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Within 90 days after the effective date of this AD, visually check the installation of the two headrest bushings and install Mecanindus pins, P/N GPMECAE2-5x5, to secure the bushings. Use the instructions in paragraph 2 of Sicma Aero Seat Service Bulletin No. 133-25-006, dated May 12, 1999, to perform the visual inspection and install the pins.
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.
