Role Two seat light aircraft
National origin France
Designer Henri Nicollier
First flight 9 June 1988
Number built 1

The Nicollier HN 500 Bengali is a single engine French light aircraft built in France in the 1980s. It seats two in side-by-side configuration. Only one was built, flying for the first time in 1988; it remains active with a French preservation group.

Design and development

The Bengali is a conventionally laid out, all wood, cantilever low wing monoplane with side by side seating. The wing has a single spar and is made in one piece; its leading edge and part of the root is skinned with plywood and the whole wing, including the ailerons and two position flaps covered with Dacron. Dihedral is constant over the span and there is 2.16° of washout. The wing is tapered in plan with less sweepback outboard.[1]

Apart from a glass fibre engine cowling the fuselage is a trapezoidal cross-section semi-monocoque with plywood stressed skin and rounded dorsal decking. The Bengali's side-by-side cabin, fitted with dual controls, is accessed via two upward opening, centrally hinged transparent sections. There is baggage space behind the seats. The swept fin is an integral part of the fuselage and the tailplane, set at mid-fuselage height, is of the semi-all-moving type with automatic tabs on both trailing edges.[1]

The Bengali is powered by a 75 kW (100 hp) Rolls-Royce built Continental O-200 flat four piston engine driving a fixed pitch propeller. The main fuel tank, holding 67 L (14.8 Imp gal) is in the fuselage under the baggage space, with more fuel held in a pair of leading edge wing tanks. It has a fixed tricycle undercarriage. The mainwheels have hydraulic brakes and the nosewheel is self centring though not steerable.[1]

Operational history

The Bengali first flew on 9 June 1988,[2] though construction was "nearing completion" in early 1981.[1] Only one was built as Nicollier chose at an early stage not to sell plans.[1][3] Shortly after its first flight this aircraft, F-PXHN, attended the RSA Internal held at Moulins-Montbligny between 29–31 July 1988.[4] It later became F-PFHN and is currently (2012) with the Groupement pour la Préservation du Patrimoine Aéronautique (GPPA) at the Musée Regional de l'Air, Angers[5] remaining in flying condition.[6]
