Included in the several factors that the NTSB says contributed to the Feb. 2, 2005 crash of a Challenger 600 at Teterboro Airport was its determination that the third crewmember, or “cabin aide,” was not properly trained. According to the Safety Board’s final report on the accident, the cabin aide “did not perform a seatbelt compliance check before the accident flight, which resulted in two passengers being unrestrained during the accident sequence.” In addition, the cabin aide’s training “did not adequately prepare her to perform the duties with which she was tasked, including opening the main cabin door during emergencies.” Thus, the NTSB is recommending that the FAA require that cabin personnel who are intended to be “qualified flight attendants” on Part 135 flights receive basic FAA-approved safety training in preflight briefing and safety checks; emergency exit operation; and emergency equipment usage. The Safety Board also said Part 135 certificate holders should be required to “ensure that seatbelts at all seat positions are visible and accessible to passengers before each flight.”
