Desin and development
The Timm S-160 (or Timm PT-160K) was a conventional tandem open-cockpit monoplane trainer first flown on the 22 May 1940 by test pilot Vance Breese. 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 molded plywood, creating a composite material stronger and lighter than plywood. This process was patented as the Nuyon process and marketed as the aeromold process. The S-160 received the first approval for a plastic-wood construction, (ATC #747), on 28 August 1941.
The PT-175-K variant was fitted with a Kinner R-53 engine. This was followed by the PT-220-C with a 220 hp (164 kW) Continental W-670-6 engine and larger tail.
The PT-220C was evaluated by the United States Navy, which ordered 262 aircraft in 1943 as the N2T-1, incorporating only slight changes from the prototypes. The N2T-1 was a U.S. Navy basic trainer which the Navy nicknamed "Tiny Timm." The entire initial order was delivered in 1943 with no follow-on contract due to the military placing too many orders for Army and Navy trainers.
Although popular and relatively reliable, the N2T-1 was not built for long-term use, especially being made almost entirely of a wood based composite material that proved to be susceptible to decomposing. Postwar, the N2T was sold to private owners and 10 remained on the U.S. civil aircraft register in 2001.
An N2T-1, tail number N56308 crashed during the Rocky Mountain Airshow at the Flagler Airport, Flagler, Colorado, 15 September 1951, killing the pilot and 19 spectators. The Mississippi director of aviation banned airshows in the state that year as a result.
