## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for Goodrich Evacuation Systems approved under TSO-C69b and installed on certain Airbus Model A330-200 and -300 series airplanes; Model A340- 200 and -300 series airplanes; and Model A340-541 and -642 airplanes. This proposed AD would require inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems, and corrective action if necessary. This proposed AD results from a report indicating that, during maintenance testing, the pressure relief valves on the affected Goodrich evacuation systems did not seal when activated, which caused the pressure in the escape slide/raft to drop below the minimum allowable raft mode pressure. We are proposing this AD to prevent loss of pressure in the escape slides/rafts after an emergency evacuation, which could result in inadequate buoyancy to support the raft's passenger capacity during ditching, and increase the chance for injuryto raft passengers.
