Safety Recommendation A-72-067
Details
Synopsis: THIS STUDY EXAMINES THE CONDITION AND CIRCUMSTANCES WHICH DETERMINED THE OUTCOME OF THE DITCHING OF A DC-9 AIRCRAFT IN REGARD TO THE SURVIVAL AND NONSURVIVAL OF THE OCCUPANTS. IT WAS FOUND THAT THE PASSENGERS WERE PREPARED INADEQUATELY FOR THE DITCHING DUE TO A COMBINATION OF FACTORS INCLUDING INSUFFICIENT PREPARATION TIME, INADEQUATE BRIEFINGS, INSUFFICIENT TRAINING AND THE LACK OF PROPER CREW COORDINATION. IT WAS ESTIMATED THAT DECELERATIVE FORCES WERE INTHE ORDER OF 8 TO 12 G'S, CAUSING UNRESTRAINED OCCUPANTS TO BE THROWN FORWARD, INDUCING SEAT FAILURES AND SPINAL INJURIES. THE CAUSE OF SEATS, SEATBELT, AND GALLEY EQUIPMENT FAILURES WERE ANALYZED. IT WAS ESTIMATED THAT THE AIRCRAFT REMAINED AFLOAT FOR 5 TO 6 MINUTES. THE FACT THAT A LIFERAFT INFLATED INSIDE THE AIRCRAFT WAS ATTRIBUTED TO IMPINGEMENT OF THE RAFT PACKAGE BY THE GALLEY STRUCTURE, FORCING THE CREWMEMBERS OUT OF THE AIRCRAFT. LEADERSHIP OF THE CREW WHILE AWAITING RESCUE AND AN INFLATED EMERGENCY ESCAPE SLIDE MINIMIZED FURTHER LOSS OF LIFE. RECOMMENDATIONS WERE ADVANCED DEALING WITH INCREASED TRAINING FOR CREWMEMBERS, BETTER PASSENGER COMMUNICATION TECHNIQUES, INCREASED STRENGTH REQUIREMENTS FOR SEATS,SEATBELTS, AND GALLEY EQUIPMENT AND THE DEVELOPMENT OF SLIDE RAFT COMBINATIONS AND LIFEVEST DESIGN. TWENTY REFERENCES ARE INCLUDED.
Recommendation: AMEND FAR PART 129, "OPERATIONS OF FOREIGN AIR CARRIERS," TO INCLUDE THE SAFETY PROVISIONS OF SUBPART T OF PART 121 GOVERNING THE BRIEFING OF PASSENGERS, OR INCLUDE THESE PROVISIONS IN THE OPERATIONS SPECIFICATIONS ISSUED TO FOREIGN AIR CARRIERS BY THE ADMINISTRATOR; AND REQUIRE THAT APPROVED WORDING FOR SUCH BRIEFINGS BE INCLUDED IN THE APPROPRIATE FLIGHT/OPERATIONS MANUALS OF THE APPLICABLE CREWMEMBERS.

Response: IN RESPONSE FAA SAID PASSENGER BRIEFINGS APPLICABLE IN THIS CASE SHOULD HAVE BEEN THE BRIEFINGS OUTLINED IN THE ONA DC-9 OPERATIONS MANUAL SINCE ONA HAD OPERATIONAL CONTROL OF THE FLIGHT.
