## Abstract

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.
