The FAA registration of N5474F lists it as a 1968 Alon A-2A. Alon manufacture is an error. The aircraft is a twin-fin development of the original twin-fin ERCO Ercoupe 415 series, produced subsequently by Forney as the F-1 and later resurrected by Alon as the A-2.
The Mooney logo on the twin fin of N5474F may puzzle the viewer. N5474F was actually made by Mooney in 1968, not by Alon as registered. In 1968 Mooney took over the design and built 38 A-2A Cadets (A and Cadet added by Mooney) from c/n B-261 to B-298; thus-Mooney was the true manufacturer of N5474F.
In 1969 Mooney offered the Cadet in a single fin redesign with characteristic Mooney shape. Mooney renamed the design M10 Cadet. Nine were built in 1969 with c/ns from 69003-690011. Production in 1970 increased with 50 built that final year of production with c/ns from 700001-700050.
Fred Weick originally designed the two-control Ercoupe in 1939 to be non-spinnable. Mooney took some criticism because the M10 now could be put in a true stall-spin with more elevator authority and a large rudder. A substantial price increase of the 1970 production M10 and the American economy tanking in 1970 killed further production of the M10 Cadet, Mooney's only two-place production design.
