What happened
On January 23, 1965, a Beagle A.109 (registration HB-EUE) was involved in an aviation incident near Storo, located in the Trento province of Italy. While in flight, the aircraft experienced a sudden engine failure, which necessitated an immediate emergency landing. The aircraft sustained heavy damage during the landing sequence.
The investigation
The investigation was based on the findings provided by the Italian Aeronautical Registry (Registro Aeronautico Italiano). The inquiry focused on the mechanical failure that led to the loss of engine power. The examination established that the engine failure was a direct result of significant oil loss.
Findings
The primary cause of the engine failure was the failure of a seal on the propeller shaft. This mechanical defect allowed engine oil to escape, resulting in the loss of lubrication and the subsequent engine malfunction.
