Cessna 340

The pilot entered the left downwind leg of the traffic pattern to land to the north. A surface wind from the west prevailed with gusts to 15 knots. Radar data revealed that the airplane was on final approach, about 1.16 miles from the runway and about 210 feet above the ground. The airplane then crashed in a pasture south of the airport, in a slight left-wing-low attitude, and came to rest upright. The cockpit and cabin were consumed in a postcrash fire. The pilot's wife, who was in the aft cabin and survived the accident, recalled that it was choppy and that they descended quickly. She recalled hearing two distinct warning horns in the cockpit prior to the crash. The airplane was equipped with two aural warning systems in the cockpit: a landing gear warning horn and a stall warning horn. The pilot likely allowed the airspeed to decay while aligning the airplane on final approach and allowed the airplane to descend below a normal glide path. Examination of the wreckage revealed that the landing gear were in transit toward the retracted position at impact, indicating that the pilot was attempting to execute a go-around before the accident. The pilot made no distress calls to air traffic controllers before the crash. The pilot did not possess a current flight review at the time of the accident. Examination of the wreckage, including a test run of both engines, revealed no evidence of a pre-existing mechanical malfunction or failure that would have precluded normal operation of the airplane.

The twin engine aircraft departed Valera Airport on a charter flight to San Antonio del Táchira with an intermediate stop in El Vigía, carrying five passengers and one pilot. All flight was completed under VFR mode but while descending to San Antonio del Táchira, weather conditions worsened and the pilot switched to IFR mode. Shortly later, control was lost and the aircraft crashed on the slope of Mt Laja, near Lobatera. The wreckage was found about 25 km northeast of San Antonio del Táchira Airport. The aircraft disintegrated on impact and all six occupants were killed.

About 14 minutes after departing on the cross-country flight in instrument meteorological conditions, the airplane was observed on radar climbing through 14,800 feet mean sea level (msl). At this time, the pilot radioed to air traffic control (ATC) that he was returning to the departure airport. About 7 seconds later, the pilot transmitted that he had lost an engine and again stated that he was returning to the departure airport. About 50 seconds later, the pilot transmitted, “We’re losing it.” There was no further communication with the pilot. Radar data revealed that at 14,800 feet msl the airplane began a right 360-degree turn at 8 degrees per second, and about 120 degrees into the turn, it began a descent averaging 5,783 feet per minute. The airplane remained in a right turn until radar contact was lost at 10,700 feet msl. The airplane impacted a 30-degree slope of a densely forested mountain about 2,940 feet msl in a near vertical, slightly right-wing-low attitude. A logger working in the area reported hearing a “very loud roaring sound,” like an airplane diving toward his location and that it seemed to be “really under power.” The logger described the weather as being “socked in,” with light rain and not much wind. Post accident examination revealed that propeller damage was the result of impact forces, with no indications of fatigue or propeller failure before impact. It was also noted that the left propeller was being operated under conditions of some power at impact, while the right propeller was not operating under conditions of significant power at impact. Based on these findings, it is most likely that the pilot experienced a partial loss of power of the right engine and, after incorrectly initiating a right turn into the failed engine, allowed the rate of turn to increase to the point that the airplane became uncontrollable before impact with terrain. The reason for the partial loss of engine power was not determined because postaccident examination of the airframe and both engines did not reveal any mechanical malfunctions or failures that would have precluded normal operation.

The pilot was on a cross-country flight near mountainous terrain when he encountered clouds along the flight path. A comparison of recorded radar data and weather reports in the local area indicated that the pilot was maneuvering near the cloud bases in an area with low visibility and ceilings. Based on the erratic and circling flight path, it is likely that the pilot was having difficulty determining his location and desired flight track when the airplane collided with terrain. Post accident examination of the airframe and engine revealed no mechanical failures or malfunctions that would have precluded normal operation.

The twin engine aircraft departed Valle de la Pascua Airport on a private flight to Charallave. While approaching Charallave-Óscar Machado Zuloaga Airport, the crew encountered limited visibility due to low clouds when the aircraft struck the slope of a mountain located near Quiripital, about 15 km southeast of Charallave Airport. The wreckage was found the following day. The aircraft disintegrated on impact and all three occupants were killed.

The pilot reported that he was cleared for a GPS approach and broke out of the clouds at 1,800 feet. He entered a left hand traffic pattern and his last recollection was turning base. He woke up in the crashed airplane which was on fire. The airplane was destroyed. An examination of airplane systems revealed no anomalies.

The airplane departed under daytime visual meteorological conditions on a cross-country flight from an airport on the east side of a mountain range to a destination on the west side of the mountains. The airplane, which had been receiving flight following, then collided with upsloping mountainous terrain in a mountain pass while in controlled flight after encountering instrument meteorological conditions. The controller terminated radar services due to anticipation of losing radar coverage within the mountainous pass area, and notified the pilot to contact the next sector once through the pass while staying northwest of an interstate highway due to opposing traffic on the south side of the highway. The pilot later contacted the controller asking if he still needed to remain on a northwesterly heading. The controller replied that he never assigned a northwesterly heading. No further radio communications were received from the accident airplane. Radar data revealed that while proceeding on a northeasterly course, the airplane climbed to an altitude of 6,400 feet mean sea level (msl). A few minutes later, the radar data showed the airplane turning to an easterly heading and initiating a climb to an altitude of 6,900 feet msl. The airplane then started descending in a right turn from 6,900 feet to 5,800 feet msl prior to it being lost from radar contact about 0.65 miles southeast of the accident site. A weather observation station located at the departure airport reported a scattered cloud layer at 10,000 feet above ground level (agl). A weather observation system located about 29 miles southwest of the accident site reported a broken cloud layer at 4,000 feet agl. A pilot, who was flying west bound at 8,500 feet through the same pass around the time of the accident, reported overcast cloud coverage in the area of the accident site that extended west of the mountains. The pilot stated that the ceiling was around 4,000 feet msl and the tops of the clouds were 7,000 feet msl or higher throughout the area. Postaccident examination of the airframe and both engines revealed no anomalies that would have precluded normal operation.

During the landing approach, a witness saw the twin-engine airplane slow and stall. The airplane crashed short of the runway, in a residential backyard. An airport manager flew with the pilot 8 days before the accident. The manager reported that during his flight the pilot flew the approach and landing with the aural stall warning horn activated. The manager advised the pilot of the aural warning, however no corrective action was taken by the pilot during that flight. An on-scene investigation revealed no preimpact mechanical anomalies. The pilot had about 12.6 hours of flight time in the accident airplane, of which 7.7 hours were dual instruction. Due to the lack of any mechanical problems with the airplane, the pilot's minimal experience in twin-engine airplanes, and his history of flying the airplane too slow, it is probable that he allowed the airspeed to decay below a safe speed, and inadvertently stalled it.
