Calibration

The airplane departed Winchester Regional Airport under VFR mode and was completing a routine point-to-point flight to Newport News/Williamsburg International Airport (PHF), Virginia after conducting a flight inspection of the ILS at Winchester Regional Airport. After takeoff, while flying at an altitude of 2,000 feet, the crew requested permission to climb but this was denied by ATC due to traffic. Awaiting an IFR clearance, the aircraft struck the slope of Mt Knob located about 30 miles southwest from Winchester Airport. All three occupants were killed.

Aircraft entered an area of forecast moderate icing. Ice detection system had been intermittently inoperative. The aircraft entered holding in icing conditions while checking flight inspection equipment. Evidence indicated crew noted ice accretion, activated surface de-ice system, ice broke loose and entered engine intakes. Both engines flamed out. During emergency descent crew initially re-starts, but neither engine would sustain power. Crew requested vectors to more distant airport. Both pilots were seen drinking previous night. Copilot had recently lost drivers license for dui. Captain had decided to retire that day. Copilot had worked in flight ops 3 days in 8 weeks and had limited training in flight inspection. Both pilots had personal stresses which may have influenced performance. Captain's contaminated thoracic blood revealed 0.057% alcohol. Putrefaction would accentuated for part of alcohol level. Copilot had trace alcohol in urine only. Both engines showed compressor fod consistent with ice ingestion. No other aircraft system or engine malfunction found.

The crew was engaged in a night calibration/inspection of the Instrument Landing System at Córdoba-Ambrosio Taravella Airport on behalf of the Directorate General of Aeronautics of the Province of Córdoba. On final approach to runway 18, the twin engine airplane crashed in unknown circumstances about 300 meters short of runway. Both occupants were killed.

The airplane was engaged in a calibration flight at New Delhi-Palam Airport on behalf of the Indian Civil Aviation Authority. While cruising at a relative low altitude, the airplane suffered an engine failure. It banked left, lost height and crashed in flames about 40 km north of Palam Airport. All eight occupants were killed.

After departure from Ashgabat Airport, the crew completed several circuits and calibration missions in the region of the Ashgabat Airport. While cruising at an altitude of 990 metres about 50 km from Ashgabat, the crew encountered poor weather conditions when the airplane struck the slope of Mt Uldepe (1,631 metres high). The aircraft disintegrated on impact and all six crew members were killed. The Ilyushin II-14 version LIK (Lyotno-izmeritelnyy Kompleks) is a special version for calibration mission only.

The crew departed Salvador-Dois de Julho Airport in the morning to proceed to a calibration mission. After a flight over the sea, the crew was returning to Salvador when, at an altitude of 1,500 feet, the right engine failed. The crew reduced his altitude and elected to divert to the nearest airport when, at an altitude of 800 feet, the left engine failed as well. In such conditions, the crew ditched the airplane off Itaparica. While both pilots were able to swim to the shore, the aircraft sank and was lost.

The crew was engaged in a calibration mission on behalf of the DGAC/SFACT (Service de Formation Aéronautique & de Contrôle Technique). In unknown circumstances, the aircraft belly landed at Saint-Yan Airport and slid for several meters before coming to rest. All four crew members escaped uninjured while the aircraft was damaged beyond repair.

The crew departed Kiev-Zhuliany Airport bound for Donetsk and Voroshilovgrad on a calibration flight. Shortly after takeoff, while in initial climb, the pilot informed ATC about a fire on the right engine. The crew was cleared to return for an emergency landing but the situation deteriorated quickly when the airplane went out of control and crashed in flames in a field located 10,8 km from the airport. The aircraft was destroyed and all six occupants were killed.

The crew was completing a calibration mission at Nairobi-Wilson Airport when the airplane crashed in unknown circumstances upon landing on runway 06. The aircraft was damaged beyond repair while all three crew members were unhurt.

The crew was engaged in a check of the Lubbock Airport facilities. During the takeoff roll, the airplane became uncontrollable, veered off runway and came to rest with its undercarriage raised. All three crew members were uninjured while the aircraft was damaged beyond repair.
