variants with their own articles = The Fairchild PT-19 was a USA Fairchild Aircraft monoplane primary trainer aircraft that served with the United States Army Air Forces, RAF and RCAF during World War II. It was a contemporary of the Kaydet biplane trainer and was used by the USAAF during Primary Flying Training as the introductory pre-solo phase trainer for introducing new pilots to flying before passing them on to the more agile Kaydet.

As with other USAAF trainers of the period, the PT-19 had multiple designations based on the power plant installed.

Design and development

The PT-19 series was developed from the Fairchild M-62 when the USAAC first ordered the aircraft in 1940 as part of its expansion program. The cantilever low-wing monoplane with fixed landing gear and tailwheel design was based on a two-place, tandem seating, open cockpit arrangement. The simple but rugged construction included a fabric-covered welded steel tube fuselage. The remainder of the aircraft used plywood construction, with a plywood-sheathed center section, outer wing panels and tail assembly. The use of an inline engine allowed for a narrow frontal area which was ideal for visibility while the widely set-apart fixed landing gear allowed for solid and stable ground handling. The M-62 first flew in May 1939, and won a fly-off competition later that year against 17 other designs for the new Army training airplane. Fairchild was awarded its first Army PT contract for an initial order on 22 September 1939.

The original production batch of 275 were powered by the inline 175 hp Ranger L-440-1 engine and designated the PT-19. In 1941 mass production began and 3,181 of the PT-19A model, powered by the 200 hp L-440-3, were made by Fairchild. An additional 477 were built by Aeronca and 44 by the St. Louis Aircraft Corporation. The PT-19B, of which 917 were built, was equipped for instrument flight training by attaching a collapsible hood to the front cockpit.

When a shortage of engines threatened production, the PT-23 model was introduced which was identical except for the 220 hp Continental R-670 radial powerplant. A total of 869 PT-23s were built as well as 256 of the PT-23A, which was the instrument flight-equipped version. The PT-23 was manufactured in the US by Fairchild, Aeronca, St Louis Aircraft Corporation and Howard Aircraft Corporation and in Canada by Fleet Aircraft Corporation as well as Fabrica do Galeao in Brazil.

During 1943, USAAF Training Command received a number of complaints about durability issues with the plywood wings of the PT-19 and the PT-23 when exposed to the high heat and/or humidity of training bases located in Texas and Florida. Maintenance officers at the USAAF overhaul depots had been forced to order replacement of the wooden wing sections after only two to three months' active service because of wood rot and ply separation issues.Sessums, Col. J.W. [http://www.ndu.edu/library/ic1/L46-084.pdf "Design and Engineering Problems of Aircraft Production".] 14 May 1946, pp. 6–8.] Subsequent to this incident, the USAAF incorporated a demand for all-metal wing sections on all future fixed-wing training aircraft.

The final variant was the PT-26 which used the L-440-7 engine. The Canadian-built versions of these were designated the Cornell for use by the Royal Air Force Empire Air Training Scheme in Canada and Rhodesia.

Operational history

Compared to the earlier biplane trainers, the Fairchild PT-19 provided a more advanced type of aircraft. Speeds were higher, the wing loading more approximated combat aircraft with the flight characteristics demanding more precision and care. Its virtues were that it was inexpensive, simple to maintain and most of all, virtually "vice-less", the PT-19 truly lived up to its nickname - the "Cradle of Heroes." It was one of a handful of primary trainer designs that were the first stop on a cadet's way to becoming a combat pilot.Thousands of the PT-19 series were rapidly integrated into the US and Comonwealth training programs, serving throughout World War II and beyond. Even after their retirement in the late 1940s, a substantial number found their way onto the US civil register. Around 100 still are flyable today.
