Government Aircraft Factories Nomad N24 — Primary-Source Documentation Collection

The Government Aircraft Factories (GAF) Nomad N24 stands as one of Australia's most ambitious indigenous aircraft programmes — a stretched, high-performance evolution of the N22 airframe, engineered for demanding STOL utility operations across remote and military environments. This collection assembles the core primary-source documentation that defined the N24's engineering identity, operational envelope, and airworthiness history.

Documents are presented as archival, static-copy editions fixed at their original publication dates, drawn from RAAF official holdings, GAF factory archives, and the Australian Government Air Safety Investigation Branch.

Engineering Context

The N24 programme introduced a stretched fuselage relative to the N22, extending the moment arm and introducing aerodynamic upwash effects that required systematic engineering resolution. Key technical themes across this collection include:

• Flaperon aeroelasticity — full-span double-slotted flaperon assembly generating high lift with localized trailing-edge turbulence
• Tailplane flutter — structural reports addressing high-frequency flutter induced by full-span trim tabs
• Longitudinal pitch stability — stick force gradient anomalies at 20° flap, resolved via trailing-edge T-strip modifications
• Powerplant — twin Allison 250-B17B/C turboprops, 400 shp each; ASTM-D-1655 Jet A/Jet A-1 primary fuel
• Performance envelope — MTOW 9,400 lbs (4,264 kg); cruise 140 knots; operational range 773 km at maximum payload
• Airworthiness directives — mandatory horizontal stabilizer inspections for torsional micro-cracking; control wheel assembly revisions; CASA Type Certificate 73-1

Permitted Uses

Historical research — Flight simulation — Museum and restoration reference — Academic and engineering study — Scale modelling

⚠️ Regulatory Notice: Under FAA 14 CFR § 43.13 and EASA Part-M, any mechanic performing maintenance on an active aircraft must use current, manufacturer-approved revision-controlled data. This archival document collection does not satisfy that requirement.

This is an archival, static-copy edition fixed at its original publication date. Intended for historical reference, flight simulation, museum restoration, and educational use only. Not approved for active airworthiness maintenance under FAA 14 CFR § 43.13, EASA Part-M, or equivalent international regulations. Operators of active aircraft must use current, revision-controlled publications from the Type Certificate holder or an authorized distributor.
