PSU and Life Vest Panel Lanyard Modification


The Eirtech Aviation Services solution includes FAA / EASA approved Service Bulletin, FAA, AMOC, FAA STC (with Right to Use) and Installation Kit (with EASA Form 1) to comply with FAA AD 2019-03-26 for Boeing 737NG family of aircraft.

This AD was prompted by a report indicating the Passenger Service Units (PSUs) became separated from the supporting airplane structure during several survivable accident sequences. This AD requires installing lanyard assemblies on the PSU and, for certain airplanes, on the life vest panel (if the aircraft is equipped with life vest panels in the PSU rail).



The Eirtech solution represents a substantial cost saving on Kit and Installation costs per aircraft over the alternate solution.
