Circumstances:
The non-instrument rated pilot obtained an abbreviated weather briefing for a flight from Las Vegas to Elko, Nevada. He was advised of mountain obscuration, icing and turbulence, and was told that VFR flight was not recommended. A VFR flight plan was filed and activated. The airplane departed Las Vegas at 1414 pdt. The last radio communications with the plane was at 1545 pdt, about 14 miles south of Elko. Several local residents reported a thunderstorm was passing through the area at that time. The airplane was located the next morning about 10 miles southwest of Elko Airport near Grindstone Peak at about 6,000 feet msl. An exam of the airframe and engine at the accident site did not disclose any mechanical problems. During a toxicology test, 4.8 mg/kg of diphenhydramine (an antihistamine) was detected in the pilot's liver tissue. Both occupants were killed.
Probable cause:
The pilot's continued flight into instrument meteorological conditions (IMC), and his failure to maintain altitude (or clearance) from mountainous terrain. Factors related to the accident were: the adverse weather conditions, high (mountainous/hilly) terrain, and the pilot's lack of instrument experience.

Circumstances:
The pilot had a 25 minutes turnaround for the accident trip from the prior flight. No witnesses were found who observed the pilot preparing for the flight or performing a preflight inspection. Company procedures specify that the pilots are responsible for loading and unloading the baggage. The manifest for the prior flight showed 54 lbs of baggage in the nose compartment. Shortly after liftoff, the pilot told the local controller that the baggage door was open and he requested a 'go around.' The local controller told the pilot to make right traffic. Multiple witnesses saw the airplane in a nose high attitude during the initial climb after takeoff. They reported the pilot entered a right turn which continued until the airplane 'fell to the ground and hit nose first.' An airline pilot witness said that the airplane's actions were a 'classic VMC roll.' Other witnesses reported that the left nose baggage compartment door was open during the takeoff and initial climb. Evidence shows that the right eng was developing little or no power. All three occupants were killed.
Probable cause:
The pilot's failure to maintain adequate airspeed while maneuvering in the traffic pattern. A factor which contributed to the accident was the pilot's failure to assure that the nose baggage compartment door was secured.

Circumstances:
A Cessna 414 collided with a level ground while attempting to land during a snow shower. The pilot reported an emergency one minute after departing ifr and requested to return to the airport under visual rules. The pilot indicated to air traffic control that 'I can't get any speed.' The visibility was variable around the airport with the lowest report of 1/2 mile. Witnesses observed the airplane traveling fast at low altitude and indicated both engines were running. Investigation revealed during servicing before the flight, the pitot tube covers were not used. About 1.5 inches of snow had accumulated on the airplane during the refueling and was brushed off. The airplane was seen flying into a snow shower and reversing course. Witnesses reported the airplane's angle of bank to be 80 to 90° with a 20° pitch down attitude. The airplane descended into a snow covered pasture. Witnesses reported the airplane leveled its wing just before impact. Manufacturer's safety and warning supplements indicate inflight ice protection is not designed to remove snow on parked aircraft. The manufacturer recommends use of heated hangars or approved deicing solutions to insure the are no internal accumulations in pitot static system ports. Both occupants were killed.
Probable cause:
The failure of the pilot to use pitot static system covers during icing conditions which resulted in a blocked pitot tube and subsequent loss of airspeed indications. This led to pilot disorientation and an invertant stall. Factors to the accident were improper snow removal and adverse weather conditions.

Circumstances:
No record could be found showing the pilot received a weather briefing prior to takeoff. Unfavorable weather was in the vicinity. Several times the pilot had difficulties understanding and complying with instructions from clearance delivery, ground control, and departure control. After takeoff the pilot requested and received an IFR clearance. During the last five minutes of flight radar returns showed the airplane changing heading from 45° to as much as 180° about 10 times and descending or ascending several times from altitudes ranging from 4,500 feet msl to 11,500 feet msl. The altitude and heading changes were not directed by controllers. About 3 minutes before the accident departure control asked the pilot if he had a problem. The pilot indicated that he did and 'we're trying to get straight.' One minute later, the pilot said 'we're all right.' Shortly afterwards, radar data showed a loss of control. Radar and communications were lost and an on ground explosion was observed as the accident occurred. An FAA flight surgeon reviewed the pilot's medical records. Within one year of the accident the pilot had 3 physical conditions and was taking 3 separate prescriptions which would have prevented him from being medically qualified to pilot an aircraft. All seven occupants were killed.
Probable cause:
The pilot's failure to maintain aircraft control due to spatial disorientation. Factors in this accident were:
1) the pilot's failure to obtain a preflight weather briefing and to properly evaluate the existing weather conditions prior to flight, and
2) reported unfavorable weather conditions, including turbulence, snow, rain, and obscuration at flight altitudes along the pilot's route of flight.

Circumstances:
The aircraft had recently been returned to service after 5 years in storage. On this flight, it was being used to transport two political candidates on their campaign itinerary. During takeoff from runway 03, the right engine lost power on the initial climb and the aircraft descended and crashed about 2 miles southeast of the airport. The pilot did not complete the emergency procedure for an engine failure. There was evidence that he did not feather the propeller, did not bank into the good engine, and did not close the cowl flaps on the inoperative engine. An exam of the right engine disclosed overheating and erosion of the #1 & #4 pistons, which resulted in holes in the top edges of the pistons. Also, there were clogged fuel injectors, contamination and corrosion of the fuel injector pump, and contamination and partial obstruction of the manifold valve. Additionally, the absolute pressure control of the turbocharger was found to be incorrectly adjusted. The pilot's medical certificate was dated 8/13/86.
Probable cause:
Failure of the pilot to perform emergency procedures for loss of engine power (including his failure to feather the propeller of the affected engine). Factors related to the accident were: inadequate maintenance, contamination in the fuel system, and overheat failure of the #1 and #4 pistons in the right engine (from preignition or detonation).

Circumstances:
During arrival, the flight crew of SkyWest Airlines flight 5855 requested a VOR/DME-B approach to the Elko Airport, which was approved. As the approach continued, the flight crew reported over the Bullion VOR. Approximately 30 seconds later, the aircraft crashed. Impact occurred at the top of a mountain, about 100 feet before reaching the VOR station. Elevation of the crash site was about 6,460 feet; minimum published crossing altitude at the VOR was 7,000 feet. The airport was 4.1 miles from the VOR at an elevation of 5,135 feet.
Probable cause:
Improper ifr procedure by the captain, and inadequate monitoring of the approach by the first officer, which resulted in a failure to maintain proper altitude during the approach. Factors related to the accident were: the terrain and weather conditions at the accident site.

Circumstances:
During the climbout, in night visual meteorological conditions, the aircraft lost right engine power. The pilot was initially cleared for one runway, but was unable to get a safe gear indication. The pilot made a 180° turn to land on the opposite runway while attempting to get a safe gear indication. On turn from base to final, with the gear down and locked, the pilot overshot final approach. The pilot then chose an unlit parking lot to make an off-airport landing. The aircraft struck a tree and a power line. The aircraft struck several parked unoccupied vehicles during the landing. The faa reported that an on-site inspection revealed a failed right turbocharger. Both occupants were seriously injured.
Probable cause:
The pilot's misjudgement of the forced landing profile. Contributing to the accident was the failure of the right turbocharger and the pilot's improper handling of the landing gear system. Occurrence #1: loss of engine power (partial) - mech failure/malf

Circumstances:
Approximately 10 minutes after takeoff, the pilot stated he was returning to land due to a problem. On final the aircraft rolled inverted and descended nose down into a residence. Engine examination revealed a failed supercharger intermediate drive shaft gear resulting in loss of supercharger on the right engine. The aircraft was approximately 300 lbs over max gross weight. The landing gear was down and the flaps were extended approx 20°. The left throttle was found in the full forward (high power) position. The right prop control was in full decrease rpm, high pitch and the right engine magneto switches were off. Witnesses had observed the aircraft descend to below traffic pattern altitude. At approx 200 feet agl a loud engine noise was heard and the slow flying aircraft pitched up, rolled right and descended vertically about 1/2 mile from the airport. The pilot had not declared an emergency or defined his problem. The pilot's last recorded flight in the Beech 65 was in February 1988. There was no record of a check-out or flight training in the aircraft. Both occupants were killed.

Circumstances:
A mechanic, who was not rated as a pilot, took the aircraft without permission and elected to takeoff at night. A witness saw the aircraft departing at about 0250 pdt. Subsequently, it crashed approximately 3 miles east-northeast of the airport in an open undeveloped area. The time of the accident was not determined, but a clock in the wreckage had stopped at 0355. There was evidence the aircraft had impacted in a nose down, inverted attitude while on a north-northeast heading. The aircraft moved only 28 feet after impact and came to rest inverted with the gear extended and the flaps retracted. No preimpact mechanical problem was found. Toxicology tests showed the pilot had a blood/alcohol level of 3,7‰ and a vitreous/alcohol level of 3,3‰. No record was found to indicate that he had engaged in any previous formal flight training. There was evidence the pilot had been under recent stress. A friend reported the pilot and his wife were 'breaking up.' The pilot's wife reported he had a drinking problem which was the reason for their separation.
