Survey / Patrol / Reconnaissance

Shortly after takeoff from Del Rio Airport, while climbing, the airplane went out of control and crashed. All three occupants were killed. They were completing a search and rescue mission to Alamogordo.

Following an uneventful patrol flight, the crew returned to Jacksonville-Towers Field and the airplane completed a belly landing before coming to rest. All five crew members escaped uninjured while the aircraft was damaged beyond repair.

Upon landing off Cape Ashizuri, the seaplane lost a float and came to rest. There were no casualties.

The crew was engaged in a reconnaissance flight after a small plane was missing in the region of Roraima. Shortly after takeoff from Ponta Pelada AFB, while in initial climb, the airplane suffered technical problems, stalled and crashed 1,500 meters past the runway end. All six occupants were injured and the aircraft was destroyed.

The four engine airplane departed Lajes Airport, Azores Islands, at 0836LT on a maritime patrol flight. About two hours later, the crew reported his position and that all went well on board. This was the last radio transmission. At 1120LT, while cruising at an altitude of 2,300 feet in a limited visibility due to foggy conditions, the airplane struck the slope of a mountain (5,200 feet high) at a speed pof 220 knots and crashed. The wreckage was found in a wooded area located near la Frontera, in the center of the island. At the time of the accident, three engines were operating while the engine n°1 was shutdown for loiter.

Crashed in unknown circumstances somewhere in Gabon. There were no casualties.

The airplane was engaged in an ice survey flight over the Vilkitsky Strait, carrying four scientists and seven crew members. The goal of the mission was to facilitate the passage of ships in the Laptev Sea. After overflying Peter Island, while cruising by night at an altitude of 250 meters, the navigator made a mistake, causing the aircraft to fly to the wrong direction. Approaching the shore at an insufficient height, the airplane struck the icy and snow covered ground, slid for about 180 meters and came to rest, about 38 km southeast of Cape Chelyuskin. All 11 occupants were rescued while the aircraft was damaged beyond repair.

Crashed in unknown circumstances into the Java Sea off the Bawean Island. The pilot was rescued while the aircraft sank and was lost.

The crew was returning to Antofagasta Airport following a maritime patrol exercice. While descending at dusk, the seaplane struck the slope of Mt Moreno located about 12 km west of the airport. The aircraft was destroyed upon impact and all six occupants were killed.

The aircraft was engaged on an aerial survey sortie in the foothills East of Velikonda range in Andhra Pradesh, India. According to the eye-witnesses and the weather information, the prevailing weather conditions over the survey region during the period were 'Cloudy weather with cloud base varying from 600 m to 750 m'. It was quite probable that the cloud base was still lower over the particular area, covering the hill tops. The pilot who was flying at an altitude of 2,000 feet when he arrived at the survey area, most probably took a left-hand turn circumventing the highest peak in the area (Nisam Konda 2,181 feet high) and then started to descend with the aim to get below the cloud base for visual flight. During the process, the pilot did not see a jutting out rock face on the adjacent hill, Podille Konda, which probably was obscured by a patch of low cloud. The aircraft collided with the rock face and caught fire.
