New Zealand National Airways Corporation Flight 441
On 3 July 1963 at approximately 9:09 am NZST, the flight, a Douglas DC-3 Skyliner, flew into a vertical rock face in the Kaimai Ranges near Mount Ngatamahinerua, at an altitude of 2460 feet (750 m).Twenty-two were killed instantly; there is evidence that one person survived the impact but died shortly afterward.However, it must be appreciated that the crew decided to descend only to the level officially designated as the minimum safe altitude in the area of the descent.Following this accident, the Civil Aviation Authority made the decision to classify the Kaimai Ranges as mountainous terrain, which raised the minimum safe altitude for the area by 1000 feet (305 m).[3] In July 2023, the recovered wreckage was included in a display at Classic Flyers Museum near Tauranga Airport, commemorating the 60th anniversary of the crash.
