The Fairchild Model 24, also called the Fairchild Model 24 Argus and UC-61 Forwarder, is a four-seat, single-engine monoplane light transport aircraft designed by the Fairchild Aviation Corporation in the 1930s. It was adopted by the United States Army Air Corps as UC-61 and also by the Royal Air Force. The Model 24 was itself a development of previous Fairchild models and became a successful civil and military utility aircraft. It first flew in 1932, and over 2230 would be produced by the time production ended in the late 1940s.
The original design had a radial engine, resulting in a blunt cylindrical nose, while the later UC-61K and UC-86 used a different engine configuration resulting in a more tapered nose; overall several different engines were used across variants.
Design and development Fairchild Aircraft was hit hard by the Great Depression in the early 1930s as airline purchases disappeared. Consequently, the company attention turned to developing a reliable and rugged small aircraft for personal and business use. The Fairchild 22 became somewhat of a hit and led directly to the new and much improved Model 24 which gained rapid popularity in the early 1930s, noted for its pleasant handling characteristics and roomy interior. Having adapted many components from the automotive industry (namely expansion-shoe brakes and roll-down cabin windows), the aircraft was also affordable and easy to maintain. In production continuously from 1932 to 1948, the aircraft remained essentially unchanged aerodynamically and internally, with the addition of extra passenger seating and optional equipment.
Designed by George Hardman's team, according to H.L. Puckett, "After the success of the F-22, the Hardman design team was directed to begin work on an enclosed airplane similar to the F-22. This design was to be known as the F-24 and was to be a side-by-side two place enclosed cabin airplane using as much design data and tooling from the F-22 as possible. The prototype F-24 was test flown at Hagerstown, Maryland late 1931.The original two seat F-24 gave way to a three place version and then to a four place model. Most of the F-24 airplanes produced were powered with the 145 h.p. Warner Scarab and later with the 165 h.p. Warner Super Scarab. The Model 24 was powered in 1935 with the Ranger 150 h.p. engine. In 1938, the F-24K and J models experienced the last major changes, one of these being the revised more graceful rudder and vertical tail later to be seen in the PT series and a 165 h.p. Ranger engine was fitted under the cowling of the K model. In 1939 the F-24 reached the peak of refinement with the addition of hydraulic brakes and a new tail assembly."
The Fairchild 24 built by Kreider-Reisner Aircraft, a division of Fairchild Aviation Corporation, remained in production from 1932 to 1948, essentially the same airframe but with various powerplant and configuration enhancements. In all, Fairchild constructed over 1,500 Model 24s, with an additional 280 being constructed by the Texas Engineering & Manufacturing Company (TEMCO) in Dallas when that company purchased the manufacturing rights after World War II.
Operational history
In civil use, the aircraft was a quick sales success, with prominent businessmen and Hollywood actors purchasing the aircraft. In 1936, the US Navy ordered Model 24s designated as GK-1 research and instrument trainers. The type was also used by the US Army as a light transport and by the Coast Guard, with the designation J2K-1. The Civil Air Patrol operated many Fairchild UC-61/24s, and some aircraft were fitted with two 100-pound bombs for what became successful missions against German U-boats off the east coast of the United States in the early stages of the Second World War. The UC-61 was also procured by the US Navy as the GK-1 and by the British Royal Air Force as the Fairchild Argus.
In 1941, the United States Army Air Forces (USAAF) placed an initial order for 163 Fairchild C-61s; however, via Lend-Lease, 161 of these were shipped abroad. Under the auspices of this program, the majority of the 525 Warner Scarab Fairchild 24s/C-61s went to Great Britain. Most of these aircraft saw service as Argus Is and improved Argus IIs and were allocated to a newly formed adjunct of the Royal Air Force (RAF), the Air Transport Auxiliary (ATA). An additional 306 Ranger-powered Argus IIIs were also used by the ATA. In British service, the majority of the Argus type operated with the ATA ferrying their aircrew to collect or deliver aircraft to and from manufacturers, Maintenance Units (MU)s and operational bases.
The Argus I was a Warner Scarab-equipped aircraft identified by its wind-driven generator located on the starboard struts, and was equipped with a black-painted propeller. The Argus II was also a Scarab-powered aircraft, usually with a transparent cabin roof. This mark was certified for heavier operational weight than the Mark I and was identified by its yellow propeller. The Argus III was equipped with the six-cylinder inverted inline Ranger engine.
Postwar
The aircraft was used by small air charter operators for short-distance taxi work and many were acquired by private pilot owners. It served with military forces as diverse as Finland, Thailand, Israel, Canada, the United States and Australia.
The last "new" Fairchild 24 was assembled in 1948 from a large inventory of leftover parts in Winfield, KS.
Ten Fairchild F24R aircraft operated for Comair (South Africa) during the period after the Second World War.

Accidents and incidents Toronto Maple Leafs NHL Hockey player Bill Barilko and his dentist Henry Hudson disappeared on August 26, 1951, aboard Hudson's Fairchild 24 floatplane, flying from Seal River, Quebec. On June 6, 1962, helicopter pilot Ron Boyd discovered the wreckage about 100 kilometres (62 mi) north of Cochrane, Ontario, about 35 miles off course. The cause of the crash was deemed to have been a combination of pilot inexperience, poor weather and overloaded cargo.Hornby, Lance. "The legend of Bill Barilko". The Toronto Sun, April 20, 2011.
Alaskan missionary Harold L. Wood (1890–1944) died in his Fairchild 24 floatplane while landing near a logging camp at Kasaan Bay (30 miles northwest of Ketchikan, Alaska) on 24 February 1944. The cause of the crash was deemed to have been a pilot's health problem.Owens, Fern Royer: Sky pilot of Alaska, Pacific Press, Mountain View CA. 1959, p. 175
