Air-ground-air involving a Fokker B.V. F27 MK 50, VH-FNA, Ballina, NSW on 27 June 1993

The pilot of the Fokker F-50 VH-FNA reported that when he was lined up on Runway 24 at Ballina and about to commence takeoff, a Piper Arrow suddenly appeared overhead the airfield, crossing the intended takeoff path. Its undercarriage was extending and the aircraft appeared to be joining the circuit for landing. A taxiing call had been made by the pilot of VH-FNA, and contact had been made with another transitting aircraft on the Mandatory Traffic Advisory Frequency. No calls were heard from the arriving aircraft by the crew of VH-FNA or by the transitting aircraft. The unannounced aircraft was observed turning base for Runway 24 when VH-FNA departed.
