The '''Civil Aviation Department Revathi''' was a light utility aircraft designed in [[India]] principally for use by that country's flying clubs.

==Description==
The Revathi was a conventional, low-wing [[monoplane]] with fixed [[Conventional landing gear|tailwheel undercarriage]] and two seats side-by-side with an optional third seat behind them. The [[fuselage]] construction was of welded steel tube, with the forward section skinned in [[aluminium]] and the tail section in fabric. The wings were of all-metal construction and originally fitted with wooden [[Flap (aircraft)|flaps]] and [[aileron]]s that were later replaced with metal surfaces. The [[Empennage|tail surfaces]] were also originally wooden but later replaced with metal.

==Development==
The Revathi first flew on 13 January 1967 and received Indian [[Type certificate|type certification]] in January 1969.

The prototype's wings and fuel system were later revised, and the resulting configuration was designated the '''Revathi Mk.II'''. It first flew in this configuration on 20 May 1970. It received its Indian type certificate on 31 October 1972.
