Mountains

While cruising under VFR mode in poor weather conditions, the aircraft struck the slope of a mountain located near Quetame. The aircraft was destroyed upon impact and all 22 occupants were killed.

Following an uneventful flight at FL140, the crew initiated the descent to Lubango Airport in poor visibility due to heavy rain falls. At an altitude of 7,400 feet, the airplane struck the slope of a mountain located near Bibala. The wreckage was found about 22 km northwest of Lubango Airport, some 20 meters below the summit. The aircraft was destroyed and all 15 occupants were killed.

Less than two minutes after takeoff from Rio de Janeiro-Santos Dumont Airport runway 20R, while in initial climb, the twin engine airplane hit the Sugarloaf Mountain located about 3,8 km south of the airport. All three occupants were killed.

After a missed approach at Asheville the flight was cleared to the Greenville-Spartanburg Airport at Greer, SC. Enroute to Greer radar contact was lost. In response to a query from Atlanta artcc the pilot verified his position as being on the 235° radial of Spartanburg VOR and 11.9 miles southwest. He was then cleared to descend to 2,700 feet and execute an ILS approach. The aircraft impacted a mountain at the 3,200 feet level. The wreckage was found on the 235° radial of the Sugarloaf mountain vortac and at 24 miles. Review of the aircraft's logbook revealed that mechanical irregularities reported were not corrected for long periods of time. No corrective action was listed for an "outer marker inop aural and visual (needs to be fixed now, since ADF is also inoperative) and 'light in #2 VOR head out'. The marker beacon was described as inoperative on three dates beginning 22 August 1981 and the ADF was described as inoperative on seven dates beginning 8 May 1981. No corrective action was listed for any entry about the marker beacon or ADF. The pilot, sole on board, was killed.

En route from Cascais to Portimão, the pilot encountered poor weather conditions when the airplane lost height and crashed on a hill located in Serra de Monchique. All four occupants were rescued.

The aircraft was chartered by a local hospital in Kyzyl to transfer to Toora-Khem 12 passengers (two patients, four accompanists and a medical team of six crew) and two pilots. After takeoff, the crew was cleared to climb to an altitude of 2,300 meters bound to the north. At 1245LT, the crew reported his position over the mountains and informed ATC about the next point of report. Shortly later, the crew decided to modify his route and to follow a shorter route when weather conditions worsened with poor visibility due to snow falls. While cruising at an altitude of 2,330 meters, the single engine airplane struck a rocky wall of 2,466 meters high. As the airplane failed to arrive at destination, SAR operations were initiated but the wreckage was found five days later, on November 6, about 76 km north of Kyzyl. The aircraft disintegrated on impact and all 14 occupants were killed.

En route on a charter flight from Johannesburg to Skukuza under IFR mode, the crew was unable to receive the NDB signal. Due to poor visibility, the crew decided to divert to Hoedspruit Airport and started the descent when the airplane stuck a hill and crashed. All 30 occupants were injured and the aircraft was destroyed.

During departure, the pilot climbed in IFR conditions to 6,000 feet. After leveling, a frequency change was made and he was cleared to 8,000 feet, which he acknowledged. About 2 minutes later, the controller radioed to the pilot that he was about 4 miles north of the airway, but there was no reply from the pilot. Shortly after that radar contact was lost and the plane crashed in mountainous terrain. Several residents in the area reported hearing extremely loud engine noises followed by complete silence. An investigation revealed that both wings had separated outboard of their respective engine nacelle assemblies. An examination of the fractures revealed the wings had separated from positive overload. The leading edges of both wings had ballooned upward, indicative of extreme airspeed. The empennage had separated in a yaw and from right torsional overload. Parts of the aircraft were found within a 1 mile arc, north of the main impact area. The pilot's recent instrument experience could not be verified. All three occupants were killed. Turbulence was forecasted below 8,000 feet.

The twin engine airplane was completing a flight from Taiping to Kuala Lumpur under call sign 'Misty 116B'. En route, while cruising over the Cameron Mountain Range, the aircraft crashed in unknown circumstances in a wooded and isolated area. The wreckage was found a day later and all seven occupants were killed.

The single engine airplane was conducting a taxi flight from Tyee Lake near Smithers and Tatlatui Lake, carrying four passengers and a pilot bound for a hunting camp. About 10 minutes after takeoff, the single engine airplane entered a valley when the pilot saw obstacles and initiated to leave the area. While performing a steep turn, the aircraft stalled and crashed in a dense wooded area, bursting into flames. The wreckage was found off track about 25 km northeast of Smithers. All five occupants were killed.
