Lockheed L-414 Hudson

During the takeoff roll, al loss of hydraulic pressure forced the crew to abort. Unable to stop within the remaining distance, the twin engine airplane overran and came to rest against an embankment. Both pilots were injured and the aircraft was damaged beyond repair. Photos via www.aussieairliners.org

The aircraft had been carrying out magnetometer survey flights from the airport for several weeks. It departed at 06:30 hours local time, reaching the survey area an hour later. At 07:50 the Doppler equipment became unserviceable and a little later light rain was encountered. The survey work was abandoned and the flight returned to Tennant Creek. At 09:14 the crew radioed that they were in the circuit area. Wind was reported to be from 070° at 14 knots. The acknowledgement of this information was the last contact with the flight. A minute later, the twin engine aircraft crashed in a prairie located 2 miles west of the runway 07 threshold.The aircraft was totally destroyed and all six on board were killed, among them a child aged 11. An examination of wreckage showed that one of the duplicated aileron control chains in the pilot's control column was broken in the region of the control wheel sprocket. A link pin had failed and this pin might have subsequently jammed the assembly as the control wheel was being rotated. Control could not be taken over by the copilot, as there was no copilot on the flight. The right hand cockpit seat and rudder pedals were removed so a crew member was able to gain access to the nose area of the aircraft for the survey work.

Carrying one pilot, a navigator and a photographer, the aircraft departed Lae on a photographic survey flight over the Wewak area, but conditions proved unfavourable for photography and it was decided to return to Lae. Lae tower was called five minutes before arrival and landing instructions were passed, in which it was advised that Runway 32 was to be used, the wind velocity being 300 degrees at 15 knots with gusts to 20 knots. Just before turning on to base leg the aircraft was cleared to do a practice asymmetric landing, but was warned to expect turbulence on the final approach. This was acknowledged by the aircraft. Witnesses agree that the aircraft was very low at the time of entering the final approach from a right-hand base leg with the left-hand propeller feathered. They also agreed that, following what sounded to be a marked increase in the power setting when 300 yards from the end of the strip, the aircraft rolled to the left and dived into the water in a partly inverted attitude. All three occupants perished. Crew: Allen Motteram, pilot, Patrick Murphy, navigator, Passenger: Gordon Murrell, photographer.

At 0735 hours, the aircraft departed Horn Island with only the normal crew on board to conduct aerial photography over the northern portion of the Cape York Peninsula. The aircraft returned to Horn Island at about midday and was refueled to full tanks. The crew lunched with the crew of World Wide Aerial Surveys Hudson VH-SMM which was also conducting aerial photography in the area. After lunch the three passengers boarded VH-AGO which set course for Weipa Mission at 1516 hours. At 1523 hours, Captain Linfoot advised the communication station on Thursday Island that he was returning to Horn Island with engine trouble and requesting that VH-SMM be held on the ground at Horn Island to render assistance if required. Following a baulked approach at Horn Island, the aircraft crashed on a tidal mud shelf 1.25 miles north-west of Horn Island Aerodrome at approximately 1535 hours. It was subsequently established that the port engine had seized as a result of a master rod bearing failure. The inquiry determined that VH-AGO had a total time of 3083 hours with 260 hours since last overhaul. The following account of the accident is extracted from "Aviation Safety Digest": "The aircraft was temporarily based at the Weipa Mission aerodrome, northern Queensland, with the normal crew consisting of a pilot, a navigator and a photographic assistant. On the day before the accident the aircraft was flown on a private flight from Weipa Mission to the Horn Island aerodrome with three non-paying passengers aboard in addition to the crew. The aircraft remained overnight at Horn Island, and early on the following morning took off with the normal crew, and carried out survey work over a period of some four hours. The aircraft returned to Horn lsland at about midday and was refueled. During the same morning another Hudson aircraft (VH-SMM of WWAS. Ed.) engaged on photographic survey work had arrived at the aerodrome and the two crews lunched together. Both aircraft were prepared for departure and the three passengers again boarded the Weipa Mission aircraft, which took-off first and set course at 1518 hours E.S.T. intending to climb to 7,000 feet en route for Weipa, 45 minutes flying time to the south. Five minutes after departure the pilot of this aircraft advised the communication station at Thursday Island that trouble had developed in the port engine and that he was returning, to land at Horn Island. He also asked that the other Hudson aircraft be held on the ground in case some assistance was needed. At the stage that this message was relayed to the captain of the second Hudson the aircraft was lined up for take-oft but immediately vacated the strip. The captain watched the circuit and approach of the other aircraft from a position clear of, but adjacent to, the threshold of Runway 08. The returning aircraft was seen to cross Runway 08 and then turn downwind at a height of 1,500-1,700 feet and proceed with a left-hand circuit towards the threshold of that runway. As the aircraft turned on to final approach at about the normal distance from the threshold but still unusually high, the ground observers noticed that the undercarriage had not been extended. The aircraft continued to descend in this configuration and it seemed likely at this stage that a wheels-up landing would be made well down the strip. When the aircraft had reached a point approximately 600 feet from the threshold and 150 feet above ground level the undercarriage was observed to extend and it was also noticed that the port propeller was feathered. At this point there appeared to be no wing flap extended and the aircraft crossed the strip threshold at a height of more than 100 feet and at a speed estimated to be well in excess of the normal approach speed. Soon after the aircraft had passed the threshold it was seen to roll and turn to port and this motion continued until the aircraft disappeared from view at such a height and angle of bank that an accident seemed imminent. The pilot of the Hudson on the ground immediately took-off and located the wrecked aircraft on a coral mud shelf just beyond the northern shore of the island. Ground parties discovered that the aircraft had been virtually destroyed by very high impact forces and the six occupants had lost their lives." Those on board at the time of the crash were: Joseph (Joe) Linfoot (Captain) Hermione Ivy (Josie) Linfoot (Wife of the Captain) Graham Holstock (Navigator) Harold Corrigan (Camera Operator) William Frank Mitchell (Director of Mitchell Aerial Services Pty Ltd, Cairns) Lionel Kenneth George Jeffery (a pilot intending to join Adastra).

Shortly after takeoff from Melbourne-Moorabbin Airport, while climbing to a height of 20 feet, the right engine failed. The aircraft stalled, hit the ground past the runway end, lost its undercarriage, went through a fence and came to rest in a field. While both crew members were unhurt, the aircraft was damaged beyond repair.

Shortly after takeoff, the twin engine aircraft suffered an engine failure resulting in its crossing the Centre Dandenong Road beneath the 20 feet high telephone wires which were strung along each side of the road before striking an earth embankment and two fences, tearing off the port wing. While all three crew members were slightly injured, the aircraft was damaged beyond repair.
