Pitts S1-S, VH-IGZ, Emkaytee (30 km SE of Darwin) NT, 2 December 1984

At the conclusion of an aerobatic display the pilot performed an inverted circuit, rolling upright as the strip was sighted on final. On short final the aircraft descended below the desired flight path and the pilot applied power. The aircraft responded but the right gear leg caught on a power line 5 metres agl and 330 metres from the threshold. The aircraft struck the ground in a steep nose down attitude and came to rest inverted. The inverted circuit had been conducted at between 50 and 100 feet above the tops of the trees.
