Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by reports of passenger service units (PSUs) becoming detached from the supporting airplane structure in several Model 737 airplane incidents that exceeded the design emergency load requirements for the PSUs. This proposed AD would require modifying the PSUs and life vest panels by removing the existing inboard lanyard and installing two new lanyards on the outboard edge of the PSUs and life vest panels. We are proposing this AD to prevent PSUs and life vest panels from detaching from the supporting airplane structure, which could lead to passenger injuries and impede passenger and crew egress during evacuation.
