The Lincoln PT-K model was the next development of the Lincoln-Page PT, designed specifically as a flight training or low cost sport aircraft. The “Page” had been dropped from the company name before the PT-K came out, so the “PT” stood for “Page Trainer”.
The PT-K was considered a well designed airplane from an aerodynamic standpoint in 1929, taking into account the ability of a student pilot. The PT-K was powered by a 100 hp Kinner K5, with a maximum speed of 104 mph.
The structure of the PT series proved to be quite rugged. The original design had a split axle landing gear configuration with a shock absorbing bungee chord. The later design featured a stiff-legged rigid gear, coupled with low pressure wheels, with enough “give” in the sidewall so that no further shock absorption was needed.
The PT-K was available with a few options, including a metal propeller, a lightly framed fully enclosed canopy for cold weather flying, navigation lights, and engine starter. One other item available as an option was Bloxham “Safety Sticks”. This option allowed the instructor to disengage the student’s control stick if a student “froze” during the flight.
EAA’s PT-K was built in November of 1930 as an open cockpit, two seat biplane. Norm Sten restored and flew the Lincoln PT-K for several years then donated it to the EAA in 1972. The AirVenture Museum flew the old Lincoln at Pioneer Airport for several years and used it for hand-prop-swinging demonstrations.
