Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Sicma Aero Seat, passenger seat assemblies. This proposed AD would require modifying the aft track fittings on these passenger seat assemblies by installing new tab locks, and then torquing the aft track fitting locking bolts. This proposed AD results from reports of loose and unlocked aft track fittings on Sicma Aero Seat, passenger seat assemblies. We are proposing this AD to prevent detachment of passenger seat assemblies, especially during emergency conditions, leading to occupant injury.
