Narrative:
Written off (damaged beyond repair) 11/3/1971 when crashed at Shinnel Head, Thornhill, Dumfriesshire. According to the following extract from the officlal AAIB report into the accident:

"The aircraft was engaged on fertiliser spreading operations over a grass covered hillside. Whilst flying at about 40 feet and 35 knots it pitched sharply nose-up to a near vertical attitude, went out of control and crashed, injuring the pilot.

The report concludes that the accident was due to a loss of control caused by the longitudinal cyclic control push rod becoming detached from the wobble plate because the retaining bolt fell out after its securing nut had come off."

The injured pilot was named in the AAIB accident report as Captain Norman Moffatt MacLeod, aged 27; he sustained slight burn injuries when the box of matches in his trouser pocket ignited. Registration G-ASIH cancelled by the CAA 6/12/71 as "PWFU" ("Permanently Withdrawn From Use")
