Owing to an engine malfunction, the crew made a forced landing on a spit in the Dodomo River in daytime in VMC. The aircraft suffered considerable damage.

Probable Cause:

The cause of the accident was the destruction of an R9SM2 rpm regulator gasket with the consequent leakage of oil from the engine lubrication system and a drop in engine power. The destruction of the gasket resulted from the shrinkage of the material, its being forced out by the pressure of the oil and its subsequent rupture.
