Détails:
The accident aircraft arrived at Charleroi-Gosselies Airport (CRL), Belgium, on January 24, 1969 after a flight from D.R. Congo.
It had operated in D.R. Congo on behalf of Cogeair for about eight months.
The Heron was parked at Gosselies until July 11, 1969, when it was going to be ferried to London-Gatwick Airport. According to documents on the airplane it had been issued a temporary certificate of registration in Congo as TN-ABA on June 5, 1969.
Congolese authorities however disputed the authenticity of the document.
The airplane departed at 15:51 hours local time. At 16:34 engine no. 4 started vibrating heavily. The pilot shut down the engine. Soon after engine no. 3 began emitting smoke and caught fire. The pilot shut down the engine but the prop failed to feather.
The airplane lost altitude and the pilot decided to carry out a forced landed in a field. It touched some trees and came to rest in a field.
CAUSE (translated from Dutch):
The cause of the accident is due to jamming in flight of two engines. The initial cause of this jamming is most likely due to non-compliance with the procedure prescribed by the manufacturer for the start-up after a somewhat long standstill of the engines.
