Boeing CH-47C Chinook, construction number B-868, RAF serial number ZD576 was originally delivered to the Royal Air Force as a Chinook HC.1 on 22 December 1984.

It was re-delivered to No 7 Squadron as a Chinook HC.2 on 21 April 1994.
On arrival at RAF Odiham, its No.1 engine had to be replaced.
On 10 May 1994, a post-flight fault inspection revealed a dislocated mounting bracket had caused the collective lever to have restricted and restrictive movement; this resulted in a "Serious Fault Signal" being sent as a warning to other UK Chinook operating units.
On 17 May 1994, emergency power warning lights flashed multiple times and the No.1 engine was again replaced.
On 25 May 1994, a serious incident occurred which had indicated the imminent failure of the No.2 engine.

On 31 May 1994, two days before the accident, two Chinook HC.1s were withdrawn from RAF Aldergrove and replaced by a single HC.2, ZD576.
On 2 June 1994, ZD576 crashed into a hillside, killing the four crew members and all passengers on board.
