## Summary

We propose to adopt a new airworthiness directive (AD) for certain Koito Industries, Ltd., seats and seating systems approved under TSO-C39b, TSO-C39c, or TSO-C127a. This proposed AD would require determining if affected seats and seating systems and their components are compliant with certain FAA regulations, and removing those seats, seating systems, and their components from the affected fleet that are shown to be unsafe. This proposed AD results from a determination that the affected seats and seating systems may not meet certain flammability and strength criteria. Failure to meet strength criteria could result in injuries to the flightcrew and passengers during emergency landing conditions. In the event of an in-flight or post-emergency landing fire, failure to meet flammability criteria could result in an accelerated propagation of fire. We are proposing this AD to prevent accelerated fires and injuries to the flightcrew and passengers.
