Mountains

While approaching La Paragua on a positioning flight from Canaima, the single engine aircraft crashed in a wooded and hilly terrain located 13 km from the destination. Both pilots were killed.

The twin engine departed Tijuana Airport at 0800LT on a flight to Guaymas with two pilots on board. On approach, the aircraft impacted a wooded mountain located 32 km short of runway. Both occupants were killed.

The aircraft departed Toluca Airport at 1516LT on a flight to Colima, carrying five members of the Colima Government and two pilots. Fifteen minutes into the flight, while cruising at an altitude of 16,000 feet, the crew informed ATC about control problems and was cleared to divert to Morelia Airport via radial 160. Shortly later, the aircraft entered an uncontrolled descent and crashed in a wooded and mountainous terrain located near El Devanador. The aircraft was totally destroyed and all seven occupants were killed.

On February 7, 2005, about 0634, Atlantic standard time, a Cessna 340, N5790M, registered to and operated by Ward County Irrigation District N°1, impacted with terrain in a mountainous area in Mendoza, Argentina. Visual meteorological conditions prevailed at the time and the flight plan information is unknown. The pilot and copilot received fatal injuries, and the airplane was destroyed. The flight originated from Aerodrome San Rafael (SAMR), Argentina, earlier that day, at an unspecified time. The initial notification from Argentina's Junta de Investigaciones de Accidentes de Aviacion Civil ( JIAAC) stated the airplane was on a cloud-seeding mission to prevent thunderstorms from developing in that agricultural area.

On February 3, 2005, a Boeing 737-242 aircraft (the "Aircraft") with Kyrgyz Republic registration EX-037, operated by Phoenix Aviation, was conducting Kam Air Flight 904 from Herat to Kabul. There were a total of 105 occupants on board the Aircraft, including eight crew members and ninety-seven passengers. The Aircraft was cruising at flight level 270 when it contacted Bagram Radar Approach Control ("Bagram") for descent and landing. The flight was normal until it failed to level at flight level 130 during the VOR/DME approach. At 1043:24 UTC, Bagram cleared the flight to descend at its discretion and to expect the VOR approach to runway 29. The prevailing weather was also passed on to the Aircraft. Visibility was reported 2 kilometers with snow, ceiling 2,200 feet broken. wind calm and altimeter setting QNH 1016. AT 1043:58 UTC, when the Aircraft was 35 miles west of the Kabul VOR. radar contact was established with Ba9ram. The Aircraft was advised by Bagram to cross the VOR at or above flight level 130 and cleared it for the VOR/DME approach to runway 29. At 1048:41 UTC the Aircraft reported flight level 130. Bagram again cleared the Aircraft for the VOR approach to runway 29 and advised the Aircraft to report procedure turn inbound. The crew replied that they would report proceeding inbound for the VOR approach to runway 29. This was the last transmission from the Aircraft. At about 1050:11 UTC, Bagram stated that radar contact had been lost with the Aircraft. Bagram and Kabul Air Traffic Control Tower attempted to locate the Aircraft through radar and radio communication, but were not successful. Search for the Aircraft was delayed and hampered due to a severe snowstorm in the region. The Aircraft was located approximately three days later by an International Security Assistance Force (ISAF) helicopter approximately 30 kilometers southeast of Kabul International Airport at N 36 27.900 E 69 30.185. The Aircraft was destroyed by force of impact from colliding with the mountain. All 105 occupants on board the Aircraft had received fatal injuries. Subsequently, all bodies were recovered and identified. The wreckage was found at the altitude of 9,960 feet (3,035 metres) on the summit of Mt Shapiri Ghar located about 30 km southeast of Kabul Airport.

The single engine aircraft departed La Paz-El Alto Airport at 0915LT on a schedule service to Sucre with 10 passengers and two pilots on board. About 45 minutes into the flight, the crew reported icing conditions. The aircraft lost height and crashed on the slope of Mt Huaricollo. All 12 occupants were rescued and the aircraft was destroyed.

The twin engine aircraft departed Puerto Ayacucho on a flight to La Carlota with 13 passengers and three crew members on board, among them seven civilians. While cruising at an altitude of 11,500 feet in poor weather conditions, the aircraft struck trees and crashed in a wooded and mountainous area located 24 km from El Junquito. The aircraft was totally destroyed by impact forces and a post crash fire and all 16 occupants were killed.

The airplane impacted mountainous terrain in an extreme nose-down attitude following a departure from controlled flight. The purpose of the flight was to check the weather conditions for passenger tour flights that day. The pilot reported about 20 minutes prior to the accident that the ceiling was 6,500 feet mean sea level (msl). Radar data showed that following this weather report, the airplane's radar track continued eastbound and upon its return westbound, at an altitude of about 6,000 feet msl, the airplane entered a series of altitude fluctuations approximately 1 mile west of a ridge that was the location of the accident, descending at 4,000 feet per minute while turning northbound, and then climbing at 3,900 feet per minute while traveling eastbound, prior to disappearing from the radar. The airplane impacted on the eastern side of the ridge. There were no monitored distress calls from the aircraft and no known witnesses to the accident. Prior to the accident, there were reports of vibrations during flight on this aircraft, although many went unreported to maintenance personnel. The day (and flight) prior to the accident, a pilot experienced a vibration during flight with passengers and it was not reported to maintenance personnel because it was logged improperly in the operator's maintenance tracking system. No corrective actions were taken. During the post accident examinations, no portions of the right elevator and trim tab were identified in the wreckage, or at the accident site. The bracket attachment to the right elevator was found loose within the wreckage and was torsionally twisted counterclockwise (aft). Ground and aerial searches for the missing parts based on a trajectory study were unsuccessful. This aircraft was equipped with a foam cored elevator trim tab that was installed during aircraft manufacture. A service difficulty report (SDR) query showed that 47 reports had been issued on elevator trim tab corrosion and many included reports of vibrations during flight. On January 20, 2005, the Federal Aviation Administration (FAA) issued Special Airworthiness Information Bulletin (SAIB) CE-05-27, which addressed potential problems with foam-filled elevator trim tabs in the accident make/model airplane, and Cessna 206 and 210 series airplanes. The SAIB indicated that the foam-filled elevator trim tabs, manufactured until 1985, were reported to have corrosion between the tab and the foam. The SAIB further said, in part, "When the skin of the trim tab becomes thin enough due to the corrosion, the actuator can pull the fasteners through the skin and disconnect. When this occurs, the tab can flutter." Some reports indicated prior instances of "vibrations in the tail section and portions of the elevator tearing away with the trim tab." Prior to the issuance of the SAIB, Cessna Aircraft Company issued a Service Bulletin (SB) SEB85-7 on April 5, 1985, that addressed elevator and trim tab inspection due to corrosion from moisture trapped in the foam cored trim tabs. Based on a review of the airplane's logbooks, the SB was not complied with, nor was the operator required to do so based on the FAA approved maintenance specifications.

While flying at 5,500 feet, the aircraft lost altitude and crashed on the slope of a mountain located near Santa Rita de Santa Teresa del Tuy, bursting into flames. The aircraft was destroyed and both occupants were killed.

On November 27, 2004, about 0820 Afghanistan time, a Construcciones Aeronauticas Sociedad Anonima C-212-CC (CASA 212) twin-engine, turboprop airplane, N960BW, registered to Aviation Worldwide Services, LLC, and operated by Presidential Airways, Inc., of Melbourne, Florida, collided with mountainous terrain in the vicinity of the Bamiyan Valley, near Bamiyan, Afghanistan. The Department of Defense (DoD) contract flight was operated under the provisions of 14 Code of Federal Regulations (CFR) Part 135, with a company flight plan filed. Daylight visual meteorological conditions (VMC) prevailed. The captain, the first officer, and the mechanic-certificated passenger, who were U.S. civilians employed by the operator, and the three military passengers, who were active-duty U.S. Army soldiers, received fatal injuries. The airplane was destroyed. The flight departed Bagram Air Base (OAIX), Bagram, Afghanistan, about 0738.
