The incident occurred on descent into New York/JFK following a scheduled service from Edinburgh Airport
A crew’s failure to adequately monitor the speed of their aircraft, leading to aggressive control inputs, injured three cabin crew members, the US National Transport Safety Board has found.
The incident occurred on September 6, 2018, as American Airlines flight 279 was descending into New York/JFK to conclude a flight from Edinburgh, Scotland.
The Boeing 757-200, N173AN (c/n 32399), was nearing 12,000ft on its descent at 12.45 local time when the autopilot’s Altitude Hold mode was engaged. After 15 seconds, the recorded altimeter setting changed from 29.92 to 30.13 inches of mercury, resulting in an immediate change to the displayed altitude. The captain reported the altitude at this time was 12,100ft and changed the mode control panel (MCP)’s auto throttle system to flight level change (FLCH) to return to 12,000ft.
