Zhigansk

The single engine airplane departed Zhigansk at 0506LT on a survey flight over the Dzhardzhan River to identify possible pollution in a water protection program. The mission was conducted over the water at a height of 100 meters, sometime down to 50 meters to inspect boats. En route, the captain asked the copilot to make some calculation for a new route to Sangar. Doing so, the copilot's attention was not focused on the flight and the captain also got distracted, leaving the aircraft descending until it struck the surface of the water. The aircraft crashed and sank. Both pilots and a passenger were able to evacuate the cabin while the second passenger drowned.

The single engine aircraft departed Vilyuysk Airport in the morning on a survey mission to prevent forest fire. One hour and 20 minutes after takeoff, the engine failed. The crew attempted an emergency landing when the aircraft crashed in a wooded area, bursting into flames. All three occupants, two pilots and one observer, were uninjured while the aircraft was destroyed by fire. The wreckage was found 195 km southwest of Zhigansk.
