Topographic

While flying at a height of 400 meters during a cartographic flight, the aircraft caught fire and went into a dive. By an angle of descent of about 70°, the aircraft crashed in a field located in Peterfeld, about 17 km west of Petropavl. The aircraft was destroyed by impact forces and a post crash fire and all five crew members were killed.

Shortly after takeoff from Novosibirsk Airport, while climbing to a height of 50 meters, the right engine failed. The pilot in command elected to make an emergency landing but the aircraft was over a forest. It hit tree tops and eventually crashed in flames 250 meters further on. Two crew members were killed while three others were injured.

En route, the crew encountered poor weather conditions with turbulences. The aircraft went out of control, dove into the ground and crashed in an open field. All five crew members were killed. It was reported that the pilot may have lost the control of the aircraft when the cargo shifted while flying in severe turbulences.

The twin engine aircraft was returning to Paris-Le Bourget following a cartographic mission. After sunset, while flying at low height, the aircraft hit a tree and crashed in a field in Châtillon-sur-Colmont. All four occupants, two photographs and two pilots, among them Robert Leriche, were killed. The accident occurred in May (the exact date remains unclear).

The single engine airplane was engaged in a topographic flight over an area located south of the canton of Saint Gallen. The aircraft crashed in unknown circumstances. While the pilot Max Brenneisen was injured, the passenger Gustav Baldinger was killed.

This Catalina had been modified to accommodate a nine lens aerial mapping camera developed by the Coast & Geodetic Survey. The aircraft was manned by a combined crew of Coast Guard and Coast & Geodetic Survey personnel when it crashed into Mount Moffett located 5 miles northwest of Adak, Aleutians Islands, while on a survey mission. All eight crew members were killed.

The single engine airplane departed Bogotá on a topographic mission on behalf of the Instituto Geográfico Militar y Catastral which became Instituto Geográfico Agustín Codazzi in 1950. While flying in stormy weather, the airplane impacted the slope of a mountain located 5 km from Guaduas. Both occupants were killed.

The pilot and his passenger, a photographer, were conducting a mapping mission over the West Kalimantan Region, Dutch Indies. En route, one of the engine failed. Both occupants tried to keep a safe altitude while throwing out all unnecessary items. Unfortunately, the pilot was unable to keep the altitude and attempted a forced landing on a beach near Ketapang. The twin engine aircraft lost its both wings and came to rest. Both occupants were uninjured and the aircraft was damaged beyond repair.

The airplane was engaged in a topographic/cartography mission, carrying one passenger and one pilot. While cruising at an altitude of 3,000 feet, the airplane collided with a Connecticut National Guard Douglas O-38. Registered 31-352, the aircraft was completing an observation flight with one pilot on board. Following the collision, both airplanes entered a dive and crashed in Rutland. Both occupants on board the Bellanca were killed while the pilot of the O-38 was able to bail out.

The crew departed Winnipegosis on a topographic mission over the area of Hilbre, north of Winnipeg. While flying in stormy weather at an altitude of 3,500 feet, the aircraft went out of control and crashed in a prairie. All three occupants were killed.
