The Timm N2T Tutor was an American training monoplane built by the Timm Aircraft Corporation, founded by Otto Timm for the United States Navy as the N2T-1.

Development

The Timm S-160 (or Timm PT-160K) was a conventional tandem open-cockpit monoplane trainer first flown on the 22 May, 1940. It was powered by a Kinner R-5 radial engine and was a low-wing cantilever monoplane with a tailwheel landing gear. It had an unusual feature in that the airframe structure was made from resin impregnated and moulded plywood.

The PT-175-K variant was fitted with a Kinner R-53 engine. This was followed by the PT-220-C with a 220hp (164kW) Continental W-670-6 engine and larger tail. The PT-220C was evaluated by the United States Navy, which ordered 262 aircraft as the N2T-1 for operation in the basic training role.^[1]

Postwar history

Postwar, the N2T was sold to private owners and ten remained on the US civil aircraft register in 2001.

Survivor

N2Ts are preserved in US museums including examples at the National Museum of Naval Aviation at Pensacola, Florida and at the museum at Kalamazoo Municipal Airport, Michigan.^[2]

Airshow crash

A N2T-1, tail number N56308 crashed during the Rocky Mountain Airshows at the Flagler Airport, Flagler, Colorado, 15 September 1951, killing the pilot and 19 spectators.^[3][4]
