The REP Type K was a sport aircraft designed and produced in France by Robert Esnault-Pelterie.^[1] beginning in 1913.^[2] Unlike his first designs, it was of conventional configuration, one of a family of related aircraft he produced around this time.^[3] A military version was produced in 1914.^[2][4]

The two-seat Type K was very similar to other REP designs of the same period.^[5] It was a conventional, shoulder-wing monoplane which seated the pilot and a single passenger in tandem in an open cockpit.^[6] It had conventional tailskid undercarriage and was powered by a piston engine in the nose driving a tractor propeller.^[6] Lateral control was via wing-warping and the aircraft featured a joystick for pitch and roll control. and a footbar for its rudder.^[5] Unusually for the day, the fuselage and tail structure was of steel tube.^[5] Some examples had a triangular fin, others had a comma-shaped fin.^[2]

A Type K was exhibited at the 1913 Paris Aero Show.^[2][5]

These aircraft saw brief service with the French Army in the months before World War I.^[6] It proved ineffective in its role as a reconnaissance aircraft because its large wings obstructed the view of the ground.^[6] The Type Ks were quickly withdrawn from service.^[6]

One example, construction number 27, is preseved at the Musée de l'air et de l'espace ("Air and Space Museum") in Paris.^[6][7]
