Amarillo

During the cross-country instrument flight rules flight, the pilot was in contact with air traffic control personnel. The controller cleared the airplane to flight level 210 and gave the pilot permission to deviate east of the airplane's route to avoid weather and traffic. A review of radar data showed the airplane heading southward away from the departure airport and climbing to an altitude of about 14,800 feet mean sea level (msl). Shortly thereafter, the airplane turned north, and the controller queried the pilot about the turn; however, he did not respond. The airplane wreckage was located on ranch land with sections of the airplane's outer wing, engines, elevators, and vertical and horizontal stabilizers separated from the fuselage and scattered in several directions, which is consistent with an in-flight breakup before impact with terrain. A review of the weather information for the airplane's route of flight showed widely scattered thunderstorms and a southerly surface wind of 30 knots with gusts to 40 knots. An AIRMET active at the time advised of moderate turbulence below flight level 180. Three pilot reports made within 50 miles of the accident site indicated moderate turbulence and mountain wave activity. An assessment of the humidity and freezing level noted the potential for clear, light-mixed, or rime icing between 10,700 and 17,300 feet msl. Postaccident airplane examination did not reveal any mechanical malfunctions or anomalies with the airframe and engines that would have precluded normal operation. It's likely the airplane encountered heavy to extreme turbulence and icing conditions during the flight, which led to the pilot’s loss of control of the airplane and its subsequent in-flight breakup.

During a preflight weather briefing, the pilot was advised of thunderstorms and intense rain showers on the route of flight. However, he filed an IFR flight plan and took off. During flight, the ATC controller advised the pilot of a level 6 cell ahead and noted that he had no report on its top. The pilot reported that he was 'not showing anything' on his radar. Attempts were made to deviate. Approximately 20 minutes later, the pilot reported the aircraft was encountering icing conditions and was losing altitude. After another 1 min and 38 seconds, he reported 'we're going in.' Subsequently, an in-flight breakup occurred. The wreckage was found scattered over a 1/2 mile area. An exam revealed that the outboard wing panels had failed in flight. Witnesses reported seeing either smoke or fire in flight before the aircraft crashed. Evidence of an electrical discharge was found on the outboard portion of the right wing. However, the pilot had not mentioned any encounter with lightning on this flight. No evidence of metal fatigue was found. All three occupants were killed.

At 1027 the pilot received a weather briefing for Holbrook, AZ. The pilot was told of forecasts for "at least moderate icing in clouds or in precipitation above the freezing level" and the briefer stated "I guarantee you moderate to severe turbulence..." for a route into Holbrook. The pilot later got weather info for Amarillo, TX and filed an IFR flt plan to Amarillo. The aircraft departed at 1150. At 1204 the pilot reported he had an engine problem. Radar plots indicate the aircraft was maintaining a climb of about 500 fpm up to 11,200 ft. Thirty seconds later the aircraft had descended to 8,500 ft. Radio and contact was lost about 1207. Based on a weather study the probable meteorological conditions that existed about the time & in the area of the accident were moderate to severe turbulence below 12,000 ft msl & while in the clouds above freezing level the aircraft likely encountered moderate to severe rime icing. The aircraft was not certificated for flt into known icing conditions. The flight was transporting prisoners for various government agencies.

Few minutes after takeoff from Aspen-Pitkin County-Sardy Field Airport, while climbing, the pilot reported engine malfunction and was cleared to return for an emergency landing. Shortly later, the airplane went out of control and crashed in flames. The aircraft was destroyed and all four occupants were killed.

While on a night cargo flight from Houma to Amarillo, one of the engine failed due to fuel exhaustion. The pilot reduced his altitude and attempted an emergency landing in a prairie. Upon landing, the airplane collided with fences and came to rest. Both occupants were seriously injured and the aircraft was damaged beyond repair.

While on a night mail flight from Amarillo to Dallas-Fort Worth Airport, the pilot encountered very bad weather conditions. The aircraft descended into ground in an area of extremely violent weather and crashed in a mountainous area located near Claude. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the pilot was found. The wreckage was discovered on 29 August 1975 in an isolated area. The aircraft was totally destroyed and the pilot was killed.

While in cruising altitude between Apple Valley and Amarillo, the pilot encountered poor weather conditions and limited visibility. He failed to realize his altitude was too low when the airplane struck the slope of a mountain located in the region of Kelso. The wreckage was found four days later and both occupants were killed.

The crew was returning to Amarillo Airport following a four-hour refueling mission. On final approach, the aircraft was unstable and banked left and right when it stalled and crashed in flames few dozen yards short of runway. The aircraft was destroyed and all five crew members were killed.

The crew was completing a training flight from Amarillo to Dallas-Fort Worth Airport. While climbing to an altitude of 41,000 feet, the crew lost control of the aircraft that entered an uncontrolled descent, dove into the ground and eventually crashed in a field located about a mile southwest of Clarendon, Texas. The aircraft was totally destroyed upon impact and both occupants were killed. Turbulences were reported in the flight area at the time of the accident.

A Continental Air Lines Vickers-Armstrongs Viscount Model 812, N243V, was landed wheels-up, almost immediately following takeoff from the Amarillo Municipal Airport, Amarillo, Texas, on July 8, 1962, at approximately 0706LT. There were no serious injuries to any of the 13 passengers or 3 crew members. The aircraft was destroyed by fire. After normal lift-off and landing gear retraction, the captain was momentarily distracted by rainwater from the window channel falling on his left shirt sleeve and he inadvertently allowed the aircraft to settle until Nos. 2 and 3 propellers struck the runway. No. 4 engine and propeller were damaged by pieces of metal thrown from the No. 3 propeller. Increasingly severe vibration, a rapidly developing right wing heaviness, and sudden and excessive rise of exhaust gas temperatures of Nos. 2 and 3 engines dictated an immediate emergency landing. This was effected, wheels up, in a harvested wheat field approximately 6,930 feet beyond the end of runway 21 and in a direction 21 degrees to the right of its extended centerline.
