GAF N24 Nomad
Originally designed in the 1960s as a STOL utility aircraft for both civil and military use. The first prototype flew in 1971.
One hundred and seventy were sold by GAF / ASTA.
Certification in accordance with the Australian Department of Transport air regulation 27 approves the use of N24A as an 18-place airliner in regular public transport as well as in normal operation. N24A is an improved version of the previous ‘stretched’ Nomad N24. It has increased passenger and load carrying capacity with an all-up-weight of 9400 pounds from the original 8500 pounds.
Production ceased in 1984 after safety concerns following a number of accidents and the loss if 54 lives.
Boeing obtained the type certificate via its 1999 acquisition of Rockwell, which had previously acquired ASTA.
Gippsland Aeronautics purchased the GAF N24 Nomad type certificate from Boeing Australia and planned to restart production.
