This is not the first time a navajo chieftain has done a beach landing at Darwin. Some 24 years ago a chieftain experienced an engine failure after take off, then flew across Darwin harbour and landed on the other side. The Darwin news showed a front page photo of the aircraft sitting just at the high tide mark. It praised the pilot for his skill in handling the aircraft and in safely landing the aircraft without injury to crew or pax. The Department of transport investigators couldnt understand why the aircraft didnt return to Darwin airport and subjected the pax to a 10 minute joyride at 20 feet across Darwin harbour. By all the rumours at the time, the pilot allegedly only feathered the failed engine when landing was assured.I cannot remember the final result of the findings but the photo clearly indicates a feathered engine.
