The FAA is adopting a new airworthiness directive (AD) for certain Sicma Aero Seat, passenger seat assemblies. This AD requires modifying the aft track fittings on these passenger seat assemblies by installing new tab locks, and then torquing the aft track fitting locking bolts. We are issuing this AD to prevent detachment of passenger seat assemblies, especially during emergency conditions, leading to occupant injury.
You are responsible for having the actions required by this AD performed within 600 flight hours after the effective date of this AD, unless the actions have already been done.
Modify aft track fittings, P/N 90-000120-790-0, by installing new tab locks, P/N 00-4399, under the locking bolts.
(g) Torque locking bolts to 17.4-to-34.7 inch pounds.
(h) Stamp amendment “Z” on the seat assembly identification plate.
(i) Use the Accomplishment Instructions of Sicma Aero Seat Service Bulletin No. 90-25-005, Issue 2, dated March 31, 1999, to do these actions.
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.
