DR400 DR400/100 General information Type Four-seat light aircraft Manufacturer Avions Pierre Robin Designer Jean Délémontez and Pierre Robin Number built 2,700+[1][verification needed] History First flight 1972 Developed from Robin DR.200 Variant Robin DR500

The **Robin DR400** is a single-engine wooden [monoplane](/source/Monoplane) produced by [Robin Aircraft](/source/Robin_Aircraft) (formerly "Avions Pierre Robin"). The Robin DR400 is widely used in flight schools and for private use in France.[2]

## Description

The Robin DR400 was released in 1972, as a development of the DR300 series. Compared to the latter, the two major differences of the DR400 are a wider [cabin](/source/Aircraft_cabin) at shoulder level and a forward-sliding canopy, a new concept introduced with the [Robin HR-1](/source/Robin_HR100) in 1969[3][*[page needed](https://en.wikipedia.org/wiki/Wikipedia:Citing_sources)*], made to replace the doors present on earlier series. The wings have a 'cranked-wing' configuration, allowing for stable cruising and safer [stalls](/source/Stall_(fluid_dynamics)). The [dashboard](/source/Dashboard) is also clearer and more elevated than on previous models, allowing easier [instrument](/source/Flight_instruments) readings.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

The main difference between DR400 models is the engine, as the cabin remains identical between versions. The low-powered models, which go up to 120hp, are called "2+2" to indicate they can carry 2 adults and 2 children (or three adults). The other models are all four-seaters, as the 180hp engine can carry 4 [passengers](/source/Passenger), a full [fuel tank](/source/Fuel_tank), and [luggage](/source/Baggage).[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

The design of the aircraft is old; it consists of a wooden canvas structure with a low, positive-[dihedral](/source/Dihedral_(aeronautics)) wing. It is the same wood and fabric type as [Jodel](/source/Jodel) wings. The [landing gear](/source/Landing_gear) is in the non-[retractable](/source/Retractable_gear), [tricycle configuration](/source/Tricycle_landing_gear), allowing easier [taxiing](/source/Taxiing), [takeoff](/source/Takeoff) and [landing](/source/Landing) than [conventional landing gears](/source/Conventional_landing_gear).[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

The DR400 is very present in France, operating as a [training aircraft](/source/Trainer_aircraft) in [flight schools](/source/Flight_training) and a rental aircraft for flight clubs. In 2019, French air clubs operated 864 DR300 and DR400 models out of the 2394 training and rental aircraft available nationwide.[2][4]

Production of the DR400 ceased in 2014, as it was replaced with the Robin DR401.[5]

## History and Development

The first [prototype](/source/Prototype) of the DR400, a 180hp "Régent", flew for the first time in [Darois](/source/Darois) in early 1972. The production of the DR400 began on 10 May of the same year.[3][*[page needed](https://en.wikipedia.org/wiki/Wikipedia:Citing_sources)*]

The 6 initial versions were:

- The DR400-180 "Régent", which first flew on 27 March 1972 with the registration F-WSQO[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

- The DR400-125 "Petit Prince", which first flew on 15 May 1972 with the registration F-WSQT[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

- The DR400-160 "Chevalier", which first flew on 29 June 1972 [*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

- The DR400-180R "Remorqueur", which first flew on 6 November 1972[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

- The DR400-140 "Major", which first flew on 16 November 1972[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

- The DR400-108 "Dauphin 2+2", which first flew on 24 November 1972[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

The naming system of the DR400 models is similar to that of the DR300 series, with the engine's [horsepower](/source/Horsepower) indicated in the version names.[3]

The top of the canopy is usually painted on these aircraft except for the 180R (which is clear to improve visibility when [towing](/source/Towing)) and the Petit Prince, whose [plexiglass](/source/Poly(methyl_methacrylate)) canopy is tinted on the top.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

In 1974, the 180R is equipped with an additional rear window, and in 1987, all DR400 versions are equipped with this feature. Although this may improve the aircraft's appearance, the additional mass greatly hinders the aircraft's flight capabilities. The addition of reinforcements and a firewall add 25kg to the aircraft's mass. Due to this addition, these modifications are later removed from the less powerful versions, in 1993.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

In 1975, the DR400-108 is renamed DR400-100 and the "Petit Prince" is renamed DR400-120. Later on, it is equipped with a new propeller and renamed "Dauphin" while the production of the DR400-100 is ceased in 1979.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

In 1980, the DR400 B Major is retired and replaced with the DR400 Major 80 (Still with 160hp). The new Major 80 has an extended range of 1375 km, making it a very attractive aircraft for travel.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

Due to its attractive price and good performance characteristics, the "Dauphin 2+2" is the most sold version of the DR400 family and remains so in the 21st century.[3]

The successor of the DR400 is the DR401, with more modern technology and increased comfort.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

Over the years, the dashboards of the DR400 have evolved. A noticeable difference is that some aircraft are not equipped with pedal-brakes but rather with a brake handle located between the two front seats. Some other differences can be noticed such as the presence (or lack of) [warning panels](/source/Annunciator_panel).[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

The DR400 is also available with a [glass cockpit](/source/Glass_cockpit).
