Incident Overview
Date: Sunday 24 January 1988
Aircraft Type: Yakovlev Yak-40
Owner/operator: Aeroflot, Privolzhsk Civil Aviation Directorate
Registration Number: CCCP-87549
Location: near Nizhnevartovsk Airport (NJC) –
ÿ Russia
Phase of Flight: Initial climb
Status: Destroyed, written off
Casualties: Fatalities: 27 / Occupants: 31
Component Affected: Engine(s)Engine(s)
Category: Accident
A twin-engine aircraft experienced a catastrophic loss of airspeed during takeoff, resulting in stall, collision with obstacles, and subsequent breakup. The engine RPMs of the first and third engines dropped significantly, followed by shutdown, leading to a loss of speed. The incident was likely caused by a reduction in engine thrust during takeoff, potentially due to throttle closure.A twin-engine aircraft experienced a catastrophic loss of airspeed during takeoff, resulting in stall, collision with obstacles, and subsequent breakup.

Description
The no.1 and no. 3 engines rpm dropped on takeoff. The no. 2 engine rpm also dropped, but recovered. The no. 1 and no. 3 engines eventually shut down, causing the aircraft to lose speed. The plane stalled, collided with obstacles and broke up. PROBABLE CAUSE: Reduction in engine thrust during takeoff, probably because the crew closed the throttle.
