Safety Recommendation History
From: FAA
To: NTSB
Date: 7/13/1972
Response: 7/13/72 THE FAA STATED THAT AS A RESULT OF THE CITED ACCIDENT, THEY ISSUED AN ALERT TO ALL OPERATORS AND OWNERS COVERING THE NEED FOR POSITIVE DOOR CLOSURE, AND RIGGING OF DOOR ACTUATING MECHANISM IN ACCORDANCE WITH THE MANUFACTURER'S INSTRUCTIONS. THEIR SUBSEQUENT EXAMINATION OF THE DOOR'S THREE PIN LATCHING DESIGN INDICATED THAT IF PROPERLY MAINTAINED AND FULLY SECURED BY THE OPERATOR, THE PROVISIONS OF FAR 23.787(B) WOULD BE SATISFIED. WITH RESPECT TO THE BEECH 99 DOOR OPENING INCIDENT, THE FAA STATE THEY ARE CONSIDERING RULEMAKING TO PROVIDE FOR A THIRD CARGO DOOR LATCH DEVICE IN ACCORDANCE WITH BEECH SERVICE INSTRUCTION 051-113. THIS ADDED PROTECTION, THEY BELIEVE, WOULD PRECLUDE THE NEED FOR INTERNAL TIE-DOWN PROVISIONS. THEY FURTHER STATED THAT FAR 135.117 REQUIRES THAT CARGO BE CARRIED IN AN APPROVED CARGO RACK, BIN, OR COMPARTMENTINSTALLED IN THE AIRCRAFT AND THAT IT BE SECURED BY A MEANS APPROVED BY THE ADMINISTRATOR. THE FAA BELIEVES THAT WITH THE PROPOSED MODIFICATION TO THE BEECH 99, AND WITH PROPER MAINTENANCE, THE CARGO COMPARTMENTS OF BOTH THE BEECH 65 AND BEECH 99 SHOULD ADEQUATELY RESTRAIN CARGO AND FULFILL THE REQUIREMENTS OF THE REGULATION. THEY THEREFORE DO NOT CONCUR WITH ANY FURTHER RULEMAKING UNDER PART 135. 8/9/72 LETTER FROM ASSISTANT SECRETARY FOR SAFETY AND CONSUMER AFFAIRS TO THE ADMINISTRATOR WITH THE FOLLOWING COMMENTS: WHEN SERIOUS RISK TO SAFETY OF FLIGHT IS THREATENED BY INADVERTANT OPENING OF CARGO DOORS, REDUNDANT SAFETY FEATURES SHOULD BE PROVIDEDTO GUARD AGAINST THIS HAZARD. -- THE FAA'S RESPONSE DOES NOT ADDRESS ITSELF SPECIFICALLY TO THE PROBLEM. THE TWO TYPES OF AIRCRAFT INVOLVED ARE CITED, BUT THE CONCEPT OF REDUNDANT PROTECTION FOR SUCH CATASTROPHIC TYPE HAZARDS SHOULD BE SPECIFIED FOR ALL AIRCRAFT.
