A Piper PA-44-180 Seminole (VH-JQF) and a Beechcraft D95A Travel Air (VH-AEM) suffered a mid-air collision at about 4100 feet, east Mangalore Airport (YMNG), Victoria, Australia. Both occupants in each aircraft were killed and the aircraft were destroyed.
The Beech Travel Air had departed Melbourne-Tyabb Airport at 10:55 hours on a training flight to Shepparton via Mangalore, and return to Tyabb. On board were an instructor and student.
At 11:11, the pilot of the Seminole, contacted air traffic control (ATC) to advise that the aircraft was taxiing for departure from Mangalore Airport. The pilot had submitted a flight plan for a round-trip IFR flight for Mangalore via Essendon and Shepparton. Also on board was an authorised testing officer, who was testing the pilot for an instrument flight rating.
The Travel Air tracked as per the flight plan and, at 11:17, began a descent from 6,000 ft above mean sea level (AMSL) for airwork at Mangalore. Radio communication with ATC indicated the airwork was to occur between 4,000 ft and ground level.
At 11:19, the air traffic controller passed traffic information to VH-AEM about VH-JQF departing from Mangalore. At 11:22, VH-JQF made a departure call from Mangalore, advising ATC of a planned climb to 7,000 ft. ATC passed traffic information about VH-AEM to the Seminole crew.
At 11:24 the two aircraft collided approximately 8 km south of Mangalore Airport at approximately 4,100 ft. All four pilots were fatally injured in the accident, and both aircraft were destroyed.

Contributing factors:
- Following receipt of verbal traffic information, the pilots did not successfully manoeuvre or establish direct communications on the common traffic advisory frequency to maintain separation, probably due to the collision risk not being recognised.
- While it is probable that the aircraft were in instrument meteorological conditions, and could not visually separate to avoid the collision; the known limitations of the see-and-avoid principle meant that the pilots were unlikely to have seen each other in sufficient time to prevent the collision even in visual conditions.
- Following receipt of a short term conflict alert, the controller assessed it in accordance with the required procedure. After considering that the pilots had been passed mutual traffic information and were required to ensure their own separation in non‑controlled airspace, the controller did not intervene further.
- While the pilots were responsible for self-separation within the Mangalore common traffic advisory frequency area, they did not have access to the same surveillance data, including automatic dependant surveillance broadcast information available to air traffic control. As a result, the pilots were required to make timely decisions to avoid a collision without the best available information.

Other factors that increased risk
- The En-Route Supplement Australia included a requirement to add 1,000 ft to the prescribed practice instrument approach ‘altitude’ at Mangalore Airport. The procedure did not detail whether this height was to be applied to the minimum descent altitude or to all approach altitudes, resulting in varied application and an increased risk of traffic conflicts.
