Accident Details
On an unspecified date, an Antonov An-2TP (converted in 2014 with a Honeywell TPE331 turbine engine) operating as flight NYA9280 departed Naryan-Mar Airport on a scheduled service to Kharuta, Republic of Komi. The aircraft carried 11 passengers and two pilots. Shortly after takeoff, while climbing to a height of 30-40 metres, the aircraft entered an excessive nose-up attitude, then rolled to the right, stalled, and crashed in a snow-covered field.
Casualties
One passenger was killed in the initial impact. Twelve other occupants were injured. Later in the evening, two additional passengers died from their injuries, and a fourth passenger passed away on 10 January 2018.
Probable Cause
The official investigation determined that the probable cause was loss of control during initial climb due to a combination of excessive weight (the total weight of the aircraft was 42 kilograms above maximum takeoff weight) and a center of gravity that was too far aft, well above the permissible limit (32%). Poor flight preparation was also cited.
