The starboard engine suffered a sudden loss of power during a standard 'wing-over' manouevre, causing loss of control. At higher altitude, the pilot could have recovered but at the relatively low-level display altitude the aircraft 'spun-in'.

The Mosquito was so totally destroyed that the cause could not be identified with 100% accuracy. However, a very extensive AIB investigation concluded that float-height stops in both carburettors had been set incorrectly and this, under certain conditions, could have caused a momentary restriction of the fuel-flow under negative-G.

This was most likely the cause ; pilot error was certainly not a factor as the flight plan and manoeuvres were well within normal limits.

Very, very sad and a grim reminder of just what a knife-edge these old aircraft operate under today and did operate under in WWII - a very slight thing could kill you.
