RECENT FLIGHTS WITH MASKS0 FEET CABIN ALTITUDE INDICATE THAT ADEQUATE OXYGEN VAS AVAILABLE. THEXYGEN CYLINDER IS INTACT. ITS REDUCER AND RELIEF VALVE WERE RECOVERED AND LEAKAGE TESTS INDICATECH LEAKAGE, WHICH IS STILL WITHIN SPECIFICATION.

THREE PIECES OF THIS CYLINDER HAVE BEENO INDICATE THAT THE CYLINDER BROKE AFTER IMPACT.
