Circumstances:
The crew was involved in a local spraying mission in the region of Hamilton, Tasmania. While cruising at an altitude of 500 feet, the pilot-in-command initiated a left turn and descended till 50 feet when the airplane struck power cables. On impact, the left wing was torn off and the aircraft crashed in flames. Both occupants were killed.
Probable cause:
It was determined that a power line was installed few days prior to the accident and apparently, the pilot was not aware of it. The crew has been briefed before flight but the chief pilots failed to inform the crew of the presence of the power line as he was convinced the crew was already aware of its presence.

Circumstances:
The pilot had flown from the farm earlier in the morning before going away for about two hours and then returning. At about 08:00 the property owner saw the plane approaching and making a low run over the airstrip apparently in order to frighten away some cattle obstructing the landing area.. The owner, a pilot himself, had experienced a similar situation before and went move the stock out of the way. He had lost sight of the aircraft for a brief period when he heard a bang and then the plane came back into view, rolling to starboard until inverted, and diving vertically into a hillside and exploding. Ground evidence showed that the Fletcher had struck with its right wing tip a 400 pound ( 180 kg ) cattle beast, killing the animal and dislodging the metal wing tip fairing which was found nearby with its leading edge crushed. Starting a few metres further on a 46 metres long scrape mark was visible on the surface having been made by the exposed end of the outer wing. The aircraft then collided with the corner of a hangar, the outboard end of the right wing contacting the building about 2.5 metres above ground level and 1 metre below the top. This impact caused the separation of the right outer wing panel. The plane, now out of control, cleared the top of another hangar and adjacent tall trees before diving into a hillside, exploding in flames and breaking up as it tumbled down the slope. The aircraft was destroyed and the pilot was killed.
Probable cause:
The investigator found that control was lost with the separation of the outer wing wing panel on impact with the hangar. Aileron control had survived the collision with the animal. Factors that may have contributed to the accident were the altitude and azimuth of the morning sun which may have dazzled the pilot and the possibility that the aircraft was affected by its own wake turbulence created by the first low run down the airstrip.

While circling near the airport, the Dove collided with a private Piper PA-30-160B Twin Comanche registered VH-WWB that was approaching Bankstown Airport on a flight from Sydney with also two people on board. Following the collision, both aircraft dove into the ground and crashed in a residential area located about 3 NM from the airfield. Both aircraft were destroyed and all four occupants were killed. Fortunately, there were no casualties on the ground. It is believed that the crew of the Dove encountered radio problems before the accident.

Circumstances:
On January 30, 1974, Pan Am Flight 806, Boeing 707-321B 'Clipper Radiant' operated as a scheduled flight from Auckland, New Zealand, to Los Angeles, California. En route stops included Pago Pago, American Samoa, and Honolulu, Hawaii. Flight 806 departed Auckland at 2014. It was cleared to Pago Pago on an IFR flight plan. At 2311, Flight 806 contacted Pago Pago Approach Control and reported its position 160 miles south of the Pago Pago airport. Approach control responded, "Clipper eight zero six, roger, and Pago weather, estimated ceiling one thousand six hundred broken, four thousand broken, the visibility - correction, one thousand overcast. The visibility one zero, light rain shower, temperature seven eight, wind three five zero degrees, one five, and altimeter's two nine eight five." At 2313, Pago Pago Approach Control cleared the flight to the Pago Pago VORTAC. Flight 806 reported leaving FL330 three minutes later and leaving FL200 at 2324. Pago Pago Approach Control cleared the flight at 2324: "Clipper eight zero six, you're cleared-for the ILS DME runway five approach - via the two zero mile arc south-southwest. Report the arc, and leaving five thousand." At 2333, the flight requested the direction and velocity of the Pago Pago winds and was told that they were 360 degrees variable from 020 degrees at 10 to 15 knots. At 2334, the flight reported out of 5,500 feet and that they had intercepted the 226 degree radial of the Pago Pago VOR. The approach controller responded, "Eight oh six, right. Understand inbound on the localizer. Report about three out. No other reported traffic. Winds zero one zero degrees at one five gusting two zero." At 2338, approach control said, "Clipper eight oh six, appears that we've had power failure at the airport. " The first officer replied, "Eight oh six, we're still getting your VOR, the ILS and the lights are showing." Approach control then asked, "See the runway lights?" The flight responded, "That's Charlie." The approach controller then said, " ...we have a bad rain shower here. I can't see them from my position here." "We're five DME now and they still look bright," the first officer responded. Approach Control replied, "´kay, no other reported traffic. The wind is zero three zero degrees at two zero, gusting two five. Advise clear of the runway." At 23:39:41, the flight replied, "Eight zero six, wilco." This was the last radio transmission from the flight. On the flight deck the windshield wipers were turned on and the flaps were set at the 50° position, which completed the checklists for landing. At 23:40:22, the first officer stated, "You're a little high." The radio altimeter warning tone then sounded twice and the first officer said "You're at minimums." He reported the field in sight and said that they were at 140 kts. At 23:40:42, the aircraft crashed into trees at an elevation of 113 feet, and about 3,865 feet short of the runway threshold. The first impact with the ground was about 236 feet farther along the crash path. The aircraft continued through the jungle vegetation, struck a 3-foot-high lava rock wall, and stopped about 3,090 feet from the runway threshold. Of the 101 occupants of the aircraft, 9 passengers and 1 crew member survived the crash and fire. One passenger died the next day; the crew member and three passengers died 3 days after the accident. One passenger died of his injuries 9 days after the accident. Thus only four passengers survived the crash.
Probable cause:
The flight crew's late recognition, and failure to correct in a timely manner, an excessive descent rate which developed as a result of the aircraft's penetration through destabilizing wind changes. The winds consisted of horizontal and vertical components produced by a heavy rainstorm and influenced by uneven terrain close to the aircraft's approach path. The captain's recognition was hampered by restricted visibility, the illusory effects of a "black hole" approach, inadequate monitoring of flight instruments, and the failure of the crew to call out descent rate during the last 15 seconds of flight.

Circumstances:
The airplane was completing a internationaal service from Auckland to Los Angeles with an intermediate stop in Papeete, Tahiti. After a night takeoff from Papeete-Faaa Airport runway 04, while climbing to a height of 300 feet, the pilot-in-command initiated a turn to the left according to departure procedures. Then the aircraft entered a left banked, lost altitude and crashed into the sea about 3 km offshore. Few debris were found floating on water and one passenger was evacuated while all 78 other occupants were killed. The aircraft sank by a depth of about 700 meters and both CVR and FDR were not found.
Probable cause:
Due to lack of evidences, the exact cause of the accident could not be determined with certainty. However, it is considered possible that the loss of control during initial climb was the consequence of an instrument failure that may have diverted the crew's attention. As the accident occurred by night over the sea, there were no visual references available and the assumption that the pilot-in-command may have suffered a spatial disorientation was not ruled out.
