Cessna 207 Skywagon/Stationair

The airplane was being positioned to another airport at night. The flight was over mountainous terrain. The airplane collided with the top of a 4,600-foot bluff. The pilot had a history of transient global amnesia. Examination of the accident site revealed a 567-foot long wreckage path, oriented along the direct course line from the departure point to the destination. Damage to the engine and propeller indicated that the engine was developing power at impact.

The pilot was departing a remote airport to begin a VFR cargo flight. The departure path took the airplane over ice covered terrain. The airport was considered to be below basic VFR conditions with light snow and fog, and the visual conditions in the area were considered to be 'flat' with the visibility from 2 to 3 miles. The pilot received a special VFR clearance out of the control zone by a flight service station specialist. After departure, witnesses observed the airplane climb to an estimated 500 feet above the ground and turn to the right. Shortly thereafter, the airplane banked to the right about 90 degrees, then descended to the ground in a wing and nose low attitude. A postaccident inspection of the airframe and engine did not reveal any mechanical malfunction.

Shortly after takeoff from San José-Tobías Bolaños Airport, while climbing, the aircraft suffered an engine failure and stalled. It crashed in a field, bursting into flames. A passenger was killed while four other occupants were injured. The aircraft was totally destroyed by a post crash fire.

The local controller instructed the pilot to go-around because of inadequate spacing in the traffic pattern. While executing the go-around, the engine lost power and the airplane crashed on a bridge after colliding with the guard railing about 1 mile from the airport. The wreckage examination showed that the fuel line between the engine driven pump and the fuel control servo was empty. The left main tank leaked for about 5 minutes; the right main fuel tank was not compromised and contained between 5 and 10 gallons of fuel. Both auxiliary fuel tanks were empty. The fuel selector valve was found selected between the right main fuel tank and the off position. There were no other engine or airframe anomalies found.

The pilot was informed by another company pilot that the higher passes were closed. He then attempted to fly through 'high pass' located near old harbor. The pilot described the weather as overcast with ceilings obscured, and flight visibility was 2 to 3 miles. The pass was snow covered. As he entered the pass he lost visual reference due to whiteout conditions and he initiated a left turn to exit the pass. Approx half way through the turn the left wing struck the mountain.

Shortly after takeoff from El Trompillo Airport, while in initial climb, the single engine aircraft entered an uncontrolled descent, struck a tree and crashed onto several houses located in a populated area by the airport. Debris were found on a large area and all seven occupants were killed as well as three people on the ground. Five other people on the ground were injured.

After receiving a special VFR (SVFR) clearance, the pilot departed the airport with a passenger on a scheduled commuter flight to a remote airport. About 14 miles north of the airport, at 1,000 feet mean sea level (msl), the pilot encountered whiteout conditions and reversed course, descending to about 500 feet msl. The pilot requested a SVFR arrival back to the departure airport and began maneuvering to intercept the inbound course. While in instrument meteorological conditions, the airplane descended and collided with flat, snow covered terrain about 5 mile north of the airport. The pilot was unable to distinguish any terrain features until impact with the ground.

Prior to departing on a scheduled air taxi flight with two passengers, the pilot obtained a weather briefing that included airmets for mountain obscuration, IFR and icing conditions. VFR flight was not recommended. A company flight that departed before the accident flight, returned to the company base due to low ceilings, after the accident flight departed. The flight departed on a VFR flight plan and encountered low ceilings in the area of mountainous terrain. The pilot began maneuvering around the terrain and during a period of obscuration, collided with several trees. The company operations manual specifies that the pilot is responsible for the conduct of the flight; however, procedures are included that detail the dispatch responsibilities, dissemination of weather information, and the director of operations responsibility to monitor and cancel flights if necessary.

Approximately 10 minutes after departure, the pilot was contacted by a company pilot flying in the opposite direction. During their conversation the pilot stated that he was 'looking for wolves.' Shortly thereafter, the company pilot told the pilot that his radio transmissions were breaking up. The pilot replied that it was probably because he was 'behind a ridge.' The company pilot temporarily went off frequency; however, when he switched back he was unable to contact the pilot. The aircraft was later located on the southwest side of a box canyon about 100 feet below the top of the ridge. The normal course line for the route typically flown by company pilots is 6 miles away. The pilot had no prior experience in mountain flying.

The PA-28, N4512Z, was westbound in level flight about 1,000 feet agl, about 2 miles north of an airport at which an intermediate stop was planned. The Cessna T207A, N6383H, was maneuvering in left turns while conducting aerial photography, and had just initiated a turn toward the east. The left wings of each aircraft were struck by the other airplane. Witnesses indicated that about 2 seconds before impact, the PA-28 attempted to avoid a collision by beginning a climbing right turn. Each aircraft continued past the other and then both spiraled to the ground. The weather conditions were clear, visibility 3 miles in haze. Neither airplane was in radar or voice contact with any FAA facility. All three occupants in both aircraft were killed.
