Land Development Aircraft
Role Experimental utility transport
Manufacturer Lockspeiser
Designed by David Lockspeiser
First flight 24 August 1971
Status Destroyed, cancelled from register.
Number built 1
The Lockspeiser LDA-01 (Land Development Aircraft) was a British seven-tenths scale research and development aircraft, which was designed and built by David Lockspeiser to prove a concept for a low-cost utility transport.

The LDA-01 was a single-seat canard monoplane, fabric covered with metal construction. It had a canard foreplane which was the same size as each mainplane. The wing was mounted at the rear-end of the box structure fuselage which was fitted with a four wheeled landing gear. It was designed to be fitted with a detachable payload container to allow easy conversion between roles, and was powered by a rear-mounted pusher engine. The LDA-01 G-AVOR first flew on 24 August 1971 at Wisley in Surrey, under the power of a 85 hp (63 kW) Continental C85 piston engine, but was later refitted with a more powerful Lycoming O-320 engine. The aircraft (which by this time had been re-registered G-UTIL) was cancelled from the aircraft register as destroyed in 1987.[1] [2]
