Landing (descent or approach)

The aircraft, a Pilatus PC-12, serial number 151, was on a scheduled domestic flight from St. John's, Newfoundland, to Goose Bay, Labrador, with the pilot, a company observer, and eight passengers on board. Twenty-three minutes into the flight, the aircraft turned back towards St. John's because of a low oil pressure indication. Eight minutes later, the engine(Pratt & Whitney PT6A-67B) had to be shut down because of a severe vibration. The pilot then turned towards Clarenville Airport, but was unable to reach the airfield. The aircraft was destroyed during the forced landing in a bog one and a half miles from the Clarenville Airport. The pilot, the company observer, and one passenger sustained serious injuries. The Board determined that the pilot did not follow the prescribed emergency procedure for low oil pressure, and the engine failed before he could land safely. The pilot's decision making was influenced by his belief that the low oil pressure indications were not valid. The engine failed as a result of an interruption of oil flow to the first-stage planet gear assembly; the cause of the oil flow interruption could not be determined.

The aircraft departed Jakarta-Halim Perdanakusuma Airport on a charter flight to Singapore, carrying expatriates who were leaving Indonesia due to political unrest. On approach to Singapore-Seletar Airport, the copilot followed the checklist but failed to arm the lift dumper which affected the antiskid system that could not be used. After landing on a wet runway surface, the crew started the braking procedure but this was insufficient so the captain applied emergency brakes which is not recommended when hydroplaning is suspected. Unable to stop within the remaining distance, the aircraft overran, lost its left wing and left main gear before coming to rest. All 80 occupants escaped uninjured while the aircraft was written off.

At 0525 eastern daylight time, a Piper Navajo PA-31, registration C-GUVK, serial number 31-7405451, with two pilots on board, took off from Dorval Airport, Quebec, on a three-day charter flight. Two passengers boarded at Rouyn, Quebec, travelling to La Grande Rivière, Quebec. All flight segments over the three-day period were planned in accordance with instrument flight rules. At La Grande Rivière, the aircraft completed a VOR/DME approach to runway 31, but could not land due to weather. A missed approach was executed, and the aircraft proceeded toward the alternate airport, La Grande 4. About 15 nautical miles north of La Grande 3, the engines misfired. The fuel selector lever was reselected, and the engines operated normally for about five minutes, and then stopped. The pilot-in-command declared an emergency and proceeded toward La Grande 3 Airport for an LOC/DME approach to runway 29. The aircraft broke through the cloud layer at approximately 300 feet above ground level and the pilot set the aircraft down in some trees beside a small lake, four nautical miles southeast of La Grande 3 Airport. The accident occurred at 0957. One of the two passengers sustained minor leg injuries. The other occupants were uninjured. They were rescued by helicopter approximately 45 minutes later. The aircraft sustained substantial damage.

On May 11, 1998, about 1349 eastern daylight time, a Cessna 421B, N17BN, registered to Quinn Industries, Inc., operating as a 14 CFR 91 personal flight, crashed into Lake Killarney, New Providence Island, Bahamas, while on approach for landing to Nassau International Airport. Visual meteorological conditions prevailed and no flight plan was filed. The airplane received unknown damage, the pilot suffered serious injuries, and two passengers suffered minor injuries. The flight originated about 26 minutes before the accident. According to initial reports, the flight originated earlier that day from St. Thomas, Virgin Islands, with a stop at Governor's Harbour, Eleuthera, for refueling. Upon landing at Governor's Harbour, the pilot was advised no fuel was available and elected to proceed to Nassau for refueling. Some time during the straight-in approach the pilot transmitted he was "low on fuel", and N17BN crashed about 400 yards short of the runway into a swamp.

The aircraft was completing a cargo flight from Cabinda to Luanda, carrying a load of 10 tons of various goods and seven crew members. On approach, at a distance of 1,850 metres from the runway threshold, the aircraft was about 13 metres above the glide so the crew increased the rate of descent by 6,6 metres per second, causing the aircraft to descend below the glide at a distance of 1,350 metres from the runway threshold. The aircraft was stabilized at a height of 12 metres at a distance of 290 metres from the runway threshold when it encountered strong winds. The aircraft nosed down while its speed dropped from 260 to 248 km/h and struck the ground short of runway threshold with a positive acceleration of 3,45 g. Upon impact, the undercarriage were torn off and the aircraft slid for few dozen metres before coming to rest. All seven crew members escaped uninjured while the aircraft was damaged beyond repair.

The twin engine aircraft departed Tenerife-Sur-Reina Sofia Airport on a taxi flight to Tenerife-Norte-Los Rodeos Airport, carrying one passenger and one pilot. While descending to Los Rodeos Airport runway 12, weather conditions worsened and the pilot was instructed by ATC to make an approach to runway 30 via a special VFR clearance. Few minutes later, while approaching at an insufficient altitude, the aircraft collided with a house under construction and crashed in a garden. The aircraft was totally destroyed and both occupants were killed. The accident occurred in IMC conditions.

While cruising at the altitude of 13,000 feet on the leg from Durban to Bulawayo, the crew informed ATC about smoke spreading in the cockpit and was cleared to reduce his altitude. Shortly later, while flying at low altitude, the pilots open the cockpit windows to allow the smoke to evacuate and elected to make an emergency landing at Vaalwater Aerodrome which offers a grassy runway of 780 metres long and 10 metres wide. After touchdown, the aircraft struck a tree on the left side of the runway, cartwheeled, lost a landing gear and came to rest. All four occupants escaped uninjured while the aircraft was damaged beyond repair.

The aircraft was completing a charter flight from Iquitos to Andoas on behalf of the Occidental Petroleum Company, carrying eight crew members and 80 employees of this company and their subcontractors. While descending to Andoas-Alferez FAP Alfredo Vladimir Sara Bauer Airport by night, the crew encountered poor weather conditions with rains falls and limited visibility. On final, the aircraft descended below the glide, collided with trees and crashed in a dense wooded area located 5 km short of runway 12. First rescuers arrived on site three hours later. Thirteen occupants included two crew members were seriously injured while 75 other occupants were killed.

Following an uneventful flight from Toussus-le-Noble, the pilot was cleared to descend to Bagnoles-de-l’Orne Airport located about 37 km northwest of Alençon. On final, weather conditions were poor with low clouds when the aircraft struck the slope of Mt des Avaloirs (417 metres high) located 20 km short of runway 30. The wreckage was found 104 metres below the summit and both occupants were killed. At the time of the accident, the ceiling was up to 100 metres from the ground.

The aircraft departed Resende Airport with eight paratroopers and three crew members on board. In altitude, the skydivers bailed out and the crew initiated a descent to return to Resende. On short final, the crew aborted the approach and completed a low pass over the runway. Then the aircraft collided with power cables and crashed near a farm located near the airport. The aircraft was destroyed and all three occupants were killed. It was reported that the right engine was at idle and its propeller was feathered at the time of impact while the left engine was at full power for unknown reasons.
