The Yakovlev Yak-9UM aeroplane, registered VH-YIX, departed Latrobe Regional Airport, Australia, for a local private flight. The aircraft was observed by witnesses to the north of Moe, Victoria performing aerobatic manoeuvers. A short time later the aircraft impacted the ground in a steep nose‑down attitude, fatally injuring the pilot and destroying the aircraft.

Contributing factors:
- While conducting aerobatic manoeuvers, the aircraft entered a spin and impacted terrain.
- The pilot initiated aerobatics lower than his flight activity endorsement permitted and well below the height required to safely recover the YAK 9 from a spin.
- The pilot had limited experience and recency in the YAK 9 and had not previously conducted aerobatics in the aircraft. He was therefore likely unaware of its unique handling characteristics and not adequately prepared to conduct the solo aerobatic flight.

Other factors that increased risk:
- The rear canopy was unsecured before take-off and consequently separated from the aircraft during flight. This increased the risk of damage to aircraft structure, distraction of the pilot and possibly adverse handling qualities.
- Post-accident examination of the aircraft identified incomplete maintenance practices, including inadequate airframe anti‑corrosion measures and insecure primary flight controls and seat fasteners.
- The aircraft was operated without the maintenance release or the flight manual, which deprived the pilot of important operational and maintenance‑related information.
