Circumstances:
The airplane crashed into houses while on an ILS approach to runway 05 at the Birmingham Airport. The weather briefing data that the captain received in Mobile was accurate, advising him to expect thunderstorms in the Birmingham area. Birmingham atis information whiskey and xray, mentioning thunderstorms, was also accurate, and the flight crew heard them, as well as information from the approach controller that the airport was experiencing thunderstorm activity. The captain and a passenger survived while 13 other occupants were killed. There were no injuries on the ground.
Probable cause:
The decision of the captain to initiate and continue an instrument approach into clearly identified thunderstorm activity, resulting in a loss of control of the airplane from which the flight crew was unable to recover and subsequent collision with obstacles and the terrain.
