Continental A 40 engine tested on the Junior

Maintenance record entry showed in 1933,  N10907 was issued an “Experimental or Restricted license to determine the feasibility of Continental A 40 engine in this type aircraft, to replace Szekely engine which is no longer manufactured. ”   This work was done by the Airtech School of Aviation in San Diego, California.

Records do not show the outcome of the testing, except that the Szekely was reinstalled.

Thanks,,,,, Randy
