Manufacture and operations edit
Lincoln-Page[note 1] were eager to take a share of the emerging trainer market. Using their Lincoln-Page LP-3 as a basis they set about designing the PT. The resultant aircraft was quite different from the LP-3, having tandem cockpits and a lengthened rear fuselage. The design bears a resemblance to the Swallow aircraft, partially from manager Victor Roos prior history with the company.[1] Structure was standard for its day:- welded steel tube warren girder fuselage with spruce spars and basswood ribs for the wings. With the ubiquitous Curtiss OX-5 the PT proved quite versatile and able to perform basic aerobatic manoeuvers without too much effort. It was awarded ATC no 181 in July 1929.[2]
The aircraft was also offered with a Curtiss OXX-6 100 hp (75 kW) engine, but no evidence exists that any were produced. However, a later variant using a Kinner K-5 radial engine was named Lincoln PT-K.
Surviving aircraft edit
A PT-K is on display at the EAA AirVenture Museum.[3] In August 2014 three other PTs were registered by the Federal Aviation Administration as owned by private pilot owners in the United States.
