Damaged in an accident 17.4.2003 when frorce landed due to engine failure at Broomsgrove Farm, Broomsgrove, Pewsey, Wiltshire. According to the AAIB report into the incident:

"Whilst cruising at approximately 2,000 feet the pilot noticed a slight engine vibration which, within a few seconds, worsened and the engine lost power. A backfire was heard and the pilot saw smoke coming from the carburettor air intake. The vibration increased when the throttle was opened. The pilot checked both the magnetos and fuel supply, with no anomalies noted, before conducting a forced landing into wind. During the landing roll, however, the aircraft tipped onto its nose coming to rest on the propeller and left wing tip. The pilot, who was uninjured, was able to climb out of the open cockpit. There was no fire.

Examination of the engine by a maintenance organisation revealed that the No 2 cylinder inlet rocker arm had failed close to the exhaust valve, with the separated portion having become jammed in the exhaust guide. The broken pieces of the rocker arm, which were returned to the AAIB for metallurgical examination, revealed a high cycle fatigue failure, which had initiated in a region of mechanical damage

The aircraft, fitted with this engine, had been operated by the current owner for some 30 years with low utilisation. The engine had completed 670 hours since overhaul, but only 170 hours since 1978. The last entry in the log book for maintenance, which would have entailed removal of the cylinders and thus the rocker arm, was in 1990. It was not possible to determine when or how the damage to the rocker arm occurred

Nature of Damage to airframe: Per the AAIB report "Propeller, engine cowling, cockpit floor and left wing tips".

Repaired and returned to service. C of A replaced by Permit to Fly 13.3.2014. Damaged when struck standing crops on take-off Hampstead Norreys 7.6.2014; repaired and returned to service. Re-registered 19.2.2016 to Thomas Ashley Jackson, Worksop, Nottinghamshire and reverted to C of A 20.4.2016. Operated [2016] by Vintage Flight Academy, Kemble, later Membury. CofA lapsed 25.5.2018; stored Sturgate 2020. Currently registered.

Note: Fitted with DHC fuselage E190 dated 4.5.39 [discovered as such 2004].
