de Havilland DH 82 Tiger Moth

 The de Havilland DH 82 Tiger Moth is a 1930s biplane designed by Geoffrey de Havilland and was operated by the Royal Air Force (RAF) and others as a primary trainer. The Tiger Moth remained in service with the RAF until replaced by the de Havilland Chipmunk in 1952, when many of the surplus aircraft entered civil operation. Many other nations used the Tiger Moth in both military and civil applications, and it remains in widespread use as a recreational aircraft in many countries. It is still occasionally used as a primary training aircraft, particularly for those pilots wanting to gain experience before moving on to other tailwheel aircraft, although most Tiger Moths have a skid. Many are now employed by various companies offering trial lesson experiences. Those in private hands generally fly far fewer hours and tend to be kept in concours condition. The de Havilland Moth club founded 1975 is now a highly organized owners' association offering technical support and focus for Moth enthusiasts.

In postwar use, large numbers of surplus Tiger Moths were made available for sale to flying clubs and individuals. They proved to be inexpensive to operate and found enthusiastic reception in the civil market, taking on new roles including aerial advertising, aerial ambulance, aerobatic performer, crop duster and glider tug.



The Tiger Moth might be confused at first glance with the Belgian-designed Stampe SV.4 aerobatic aircraft which had a very similar design layout, with similar main landing gear, slight wing sweepback for both airframes, and similar engine/cowling design. Several Tiger Moths were converted during the 1950s to Coupe standard with a sliding canopy over both crew positions, not unlike the Canadian-built Fleet Finch biplane trainers which served beside the Tiger Moth in RCAF service as trainers in Canada during the war years. Many ex-RAF examples imported to the Netherlands post war were required by the Dutch civil aviation authorities to be fitted with additional fin area, incorporating an extended forward fillet to the fin.

After the development of aerial topdressing in New Zealand, large numbers of ex-Royal New Zealand Air Force Tiger Moths built in that country and in the United Kingdom were converted into agricultural aircraft. The front seat was replaced with a hopper to hold superphosphate for aerial topdressing. From the mid-1950s, these topdressers were replaced by more modern types such as the PAC Fletcher, and a large number of New Zealand Tiger Moths in good flying condition were then passed to pilot owner enthusiasts. It has been claimed that more people have flown themselves in Tiger Moths than in any other plane.

Royal Navy Tiger Moths utilised as target tugs and "air experience" machines became the last military examples when that service purchased a batch of refurbished ex civil examples in 1956. One became the last biplane to land on an aircraft carrier (HMS Eagle) in the English Channel during the Summer of 1967. On take-off the wind over the deck meant she took off but was slower than the carrier, which turned hard to starboard to avoid a possible collision.[citation needed] These planes remained in service until the early 1970s.

Tiger Moths were often modified to stand in for rarer aircraft in films. Notably, Tiger Moth biplanes were used in the crash scenes in The Great Waldo Pepper, standing in for the Curtiss JN-1. Due to the popularity of the design and the rising cost of flyable examples, a number of replicas (scale and full size) have been designed for the homebuilder, including the Fisher R-80 Tiger Moth and the RagWing RW22 Tiger Moth.
