7 Pertinent Report Statements “One of the passengers tried unsuccessfully to open the emergency door [overwing exit]. As a result of the fuselage being bent out of shape, the door was jammed in its frame.”“All the occupants left the aircraft through the main door, which proved difficult to open because the fuselage was bent out of shape.”Report’s Finding as to Risk:“The armrest of the side seat had not been removed as required and was blocking access to the emergency exit, which could have delayed the evacuation, with serious consequences.”
9 ConcernThe policy memo ANM ’s Background and Relevant Past Practice section discusses A05Q0024 and restates its findings as to risk and then states “the airplane occupants exited out the main door exit, the only other exit, but not without difficulty. The main door exit was difficult to open because the fuselage was bent out of shape. One passenger who tried to open the main door exit was unable to do so. This delayed the evacuation.”The policy memo implies that for this incident the escape hatch was not utilized because the divan armrest was not positioned for TTL. It also incorrectly states that a passenger tried to open the main door exit, when in fact the report states the passenger tried to open the escape hatch which was unopenable due to fuselage deformation.
