Piper PA-28-161 Cherokee Warrior II, G-BSPM

Summary:

During a training flight the aircraft experienced a rapid loss of engine power. The instructor took control and made a forced landing in a ploughed field during which the aircraft became inverted. The loss of power was attributed to a failure of the propeller reduction gearbox due to oil loss from a cracked union on the oil cooler. Analysis of data recorded by the engine鈥檚 Full Authority Digital Engine Control (FADEC) unit confirmed that a defect within the propeller system had been apparent prior to takeoff and that the engine had been 鈥榦verspeeding鈥� shortly after commencing the takeoff. No warnings or cautions were observed by the pilot or instructor until approximately 20 seconds before the loss of engine power.
