This aircraft, Richard Grubb’s first, in which he won the 1936 Folkstone Air Race, was really a Dutch Koolhoven F.K. 41 built under licence by the Desoutter Aircraft Company at Croydon. It was first registered 6.6.31 to the British Red Cross, 7.35 to F/Lt W.D. Guyler and F/Lt A.E. Clouston. It passed to Richard Grubb in 10.36, sold to C.G.M. Alington on 23.6.38 who used it in the June 1938 Isle of Man Air Race. Purchased by A.A. Rice on 30.3.39. It was impressed by the Air Ministry in May 1942 and given the service designation HM560. After storage at 5 MU and 27 MU it ended its days as a 'hack' aircraft for a Vickers Armstrong overseer.  It is pictured above at Castle Grace.

But it was in this second aircraft, an Aeronca,  that he lost his life, aged 22,  over the Irish Sea on 8th.July 1937.
As the report below shows,  he was heading towards Baldonnell Aerodrome,  where he would have cleared customs, but following a final sighting at Hollyhead,  he was never seen again.

It is an Aeronca 100, one of 24 built under license by the Aeronautical Corporation of Great Britain, Ltd at Peterbrough. It is almost identical to the US built Aeronca C-3 but employs a J.A.P. Model J99 engine (by J.A. Prestwick, Ltd), a British version of the Aeronca E-113C engine.  Infor courtesy of -
