The Boeing Stearman was manufactured as an initial training aeroplane by Boeing Aircraft Company (Witchita Division), which eventually constructed at least 8500 Stearmans, or more than 10,300 if one includes spare parts. No other biplane was ever built in this quantity. Beginning in 1934, the Americans sold the Stearman for export as the 'Kaydet.'
The RCAF's 300 Model PT-27's were ordered with special modifications for air training, particularly in Canada's winter weather conditions. The PT-27 required navigation lights, an enclosed, heated cockpit and a blind-flying hood; however, only one Stearman arrived with the enclosed cockpit. After four months of active service with the BCATP, the PT-27s were traded to the US for Fairchild Cornells because of the unsuitability of the open cockpit for winter training.
The CWH aircraft was built in 1942 and is a Model PT-17, which was donated to the collection in 1986. The Stearman is painted in the training colours and markings of a BCATP Elementary Flying Training School (EFTS). Although this aeroplane is a PT-17, the serial number FK107 was chosen to represent the last of the open-cockpit PT-27s supplied to the BCATP.
