Survey / Patrol / Reconnaissance

While completing a maritime patrol flight over the northwestern coast of Sri Lanka by night, the aircraft crashed in unknown circumstances in the sea. all four crew members were killed.

Crashed in unknown circumstances. There were no casualties.

Crashed in unknown circumstances near Jonggol, killing all six occupants, among them high ranking officers.

The aircraft was dispatched out from Elmendorf AFB on an AWACS survey mission under call sign Yukla 27, carrying 20 passengers and four crew members. Shortly after takeoff from runway 05, while in initial climb, the aircraft collided with a flock of Canada geese that struck both left engines n°1 and 2. The aircraft climbed to a maximum height of about 250 feet when the engine n°1 failed and the engine n°2 exploded. The aircraft entered an uncontrolled left roll, causing the left wing to struck trees. Out of control, it crashed in a huge explosion in a wooded area located about a mile from the runway end. The aircraft disintegrated on impact and all 24 occupants were killed. Numerous dead geese were found at the crash site.

Shortly after takeoff from Mezhdurechensky Airport, while on a forest patrol flight to Uray, the engine did not have sufficient power and the aircraft was unable to gain sufficient height. It struck power cables, stalled and crashed 2 km from the airfield. All 25 occupants were injured, four of them seriously, and the aircraft was damaged beyond repair.

The aircraft departed Sibay on a special flight to Magnitogorsk, carrying five members of the Civil Defense and two pilots. The purpose of the mission was to fly over the Ural River to study and predict flood activity. After takeoff, while in initial climb, the crew initiated a left turn when the aircraft entered an uncontrolled descent and struck the ground in a nose down angle of 40° about 1,280 metres from the runway end. A pilot and two passengers were killed while four other occupants were injured. The aircraft was destroyed.

While completing a maritime survey flight off Masirah Island, the crew encountered technical difficulties when the propeller detached from the engine n°4 that caught fire. Shortly later, the engine n°3 lost power then engine n°1 & 2 also lost power and failed. The aircraft lost height but the crew was able to regain control at 2,500 feet and eventually ditched the aircraft 8 km offshore. All 11 occupants were quickly rescued while the aircraft sank and was lost.

While flying at a height of about 380 feet, the twin engine aircraft went out of control and crashed in unknown circumstances in the region of Omarumba. Both occupants were killed.

The aircraft was engaged in aero-magnetic survey operations in an area which extended from approximately 40–130 km south of Cloncurry. The task involved flying a series of north-south tie lines spaced 2 km apart at a height above ground of 80 m and a speed of 140 kts. At this speed, each tie line occupied about 20 minutes of flight time. The flight was planned to depart Cloncurry at 0700–0730 EST and was to return by 1230 to prepare data collected during the flight for transfer to the company’s head office. An employee of the operating company saw the crew (pilot and equipment operator) preparing to depart the motel for the airport at about 0500. No person has been found who saw the crew at the aerodrome or who saw or heard the aircraft depart. At about 1000, three witnesses at a mining site in the southern section of the survey area saw a twin-engine aircraft at low level heading in a northerly direction. One of these witnesses, about 1.5 hours later, saw what he believed was the same aircraft flying in an easterly direction about 1 km from his position. Between 1000 and 1030, two witnesses at a mine site some 9 km north of the survey area (and about 5 km west of the accident site) heard an aircraft flying in a north-south direction, apparently at low level. On becoming aware that the aircraft had not returned to Cloncurry by 1230, a company employee at Cloncurry initiated various checks at Cloncurry and other aerodromes in the area, with Brisbane Flight Service, and with the company’s head office later in the afternoon. At about 2030, the employee advised the company chief pilot that the aircraft was overdue. The chief pilot contacted the Civil Aviation Authority Search and Rescue organisation at about 2045 and search-and-rescue action was initiated. The burnt-out wreckage of the aircraft was found early the following morning approximately 9 km north of the survey area.

Operated by the Peruvian Government, the single engine aircraft was engaged in a survey flight on behalf of the drug enforcement program. It crashed in unknown circumstances near Huánuco, killing all three occupants.
