National Aircraft Corp C-3
The 1929 National Aircraft Corp C-3 was a three place, open cockpit biplane. Two examples were built; NX334E c/n 100 and NX335E c/n 101. Power was an 80hp Anzani and 150hp Hisso A.
National Aircraft Aircub Sport
The single example of the 1929 Aircub Sport built, NX27N c/n 2, was designed by Leo C Mohme as a two place open cockpit biplane. Power was originally an 80hp Lee radial, replaced by a 90hp Lambert R-266 in 1930. The registration was cancelled on 1 January 1932.
National Aerospace Laboratories NM5 / C-NM5 / Mahindra Aerospace NM5 / C-NM5

The NM5 or C-NM5 is a multi-role, multi-mission aircraft being jointly developed by National Aerospace Laboratories (NAL) and Mahindra Aerospace. It is a 5-seater civil aircraft and an extension of the Hansa project. The NM5 has been entirely designed and developed by NAL and Mahindra Aerospace on a 50:50 partnership basis. The NM5 can be used as a trainer, for transporting cargo, medical evacuation, tourism, VIP travel and for training pilots.
This new 4/5 passenger General Aviation aircraft programme was launched as a part of the 10th FYP network programme. Following the successful certification of HANSA-3, NAL proposed the development of a 5-seater general aviation aircraft to be carried out during the 10th plan. However the proposal was approved only in May 2005 and thus spilled over into the 11th plan also. Work on preliminary design of the aircraft commenced in October 2006.
NAL signed an MoU with M/s Mahindra Plexion Pvt Ltd (MP) to jointly develop the 5 seater general aviation aircraft, NM5 and to undertake its production and marketing. This represents the one of the recent public-private partnership programmes in aircraft design for NAL and in the civil aviation sector in India.
At the Indian Civil Aviation Airshow (2008) held at Begumpet Airport, Hyderabad between 15–18 October 2008, the 5 seat NM5 aircraft (general aviation aircraft) attracted a lot of interest in business visitors and the general public. The NM5 was exhibited during Aero India for people to see. The NM5 and the Saras models were the biggest attractions in seventh edition in the 160 square metre Indian stall at the Aero India was held from February 11–15, 2009.

The engine, propeller and certified seats of the aircraft have been imported as the raw material like aluminium alloy sheets and hardware such as, nuts, bolts, washers and rivets. Prototypes of NM-5 are ready and the certification will take a year. The Directorate General of Civil Aviation is expected to certify the aircraft by December next year. The first prototype of the 5-seater civil aircraft made its maiden flight on 1st sept 2011 at GippsAero’s flight testing facilities near Melbourne, Australia.

An NM-5 was expected to be priced around $400,000; between Rs 1.2 crore and Rs 1.4 crore.

Nash Petrel / Procter Aircraft Associates Petrel

The Nash Petrel also known as the Procter Petrel is a two-seat aerobatic or glider tug aircraft. It was designed for amateur production by Procter Aircraft Associates of Camberley, Surrey, England.
Based on the earlier Mitchell-Procter Kittiwake design, the Petrel is an all-metal low-wing cantilever monoplane of conventional design powered by a 130 hp Rolls-Royce Continental O-240-A piston engine. By the time the aircraft first flew on 8 November 1980, Procter had changed ownership and had been renamed Nash Aircraft Ltd.
Only two aircraft were built, the prototype registered G-AXSF and one built by apprentices at the British Aircraft Corporation factory at Preston in 1973, registered G-BACA. G-BACA had a serious fault with the landing gear and only flew 15 hours before being grounded. The prototype still exists but without a current certificate of airworthiness. It is presently fitted with a Lycoming O-360-A3A engine.
