Jabiru - Jabiru

The aircraft was nearing the completion of a scenic flight, maintaining about 800 feet above ground level, when the engine power reduced to 20 inches hg manifold pressure. The engine continued to run smoothly but failed to respond when the pilot advanced the throttle. All other means attempted by the pilot to restore the lost power were unsuccessful. The aircraft, which had a full compliment of persons on board, was too heavy to maintain height under these conditions. As it was flying over forest the pilot turned the aircraft towards the south-west where a more favourable open area, with a road and an airstrip, was available. This entailed having to cross an escarpment, but due to the aircraft's rate of descent insufficient height remained, committing the pilot to a forced landing in an unsuitable area. The pilot transmitted a distress call, gave the passengers a thorough briefing and prepared the aircraft for the forced landing. The aircraft was slowed down and allowed to sink slowly into the forest, contacting the first tree about seven metres above ground level. It then continued through the trees for 40 metres before coming to rest inverted on the forest floor. All passengers evacuated from the aircraft and were rescued by a helicopter which had responded to the distress call.
