On August 26, 1993, a Let L-410 (registration RA-67656) operated by Sakha Avia - Sakha Airlines was involved in an aviation accident near Aldan, Russia during landing or approach. 24 people were killed. Investigators recorded the probable cause as: The aircraft's center of gravity was outside of safe limits due to excessive weight and improper baggage loading in the rear compartment. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 3 related events involving the same aircraft type or operator are linked below.

An aircraft crashed short of the runway at Aldan Airport during a missed approach attempt, resulting in the loss of all 24 people on board.

What happened

During the final approach to Aldan Airport, the crew of the aircraft attempted to configure the plane for landing by extending the flaps to 42°. At a speed of 196 km/h, the aircraft experienced a sudden nose-up pitch to 42.5°. In response to this change in attitude, the flight crew initiated a go-around procedure. However, as the airspeed decreased to 52 km/h, the aircraft entered a stall.

The subsequent impact occurred approximately 273 metres before reaching the runway threshold and 160 metres to the left of the extended centerline. The force of the crash resulted in the total destruction of the aircraft and caused 24 fatalities, with no survivors among the occupants.

Findings

Investigations into the accident revealed that the aircraft was operating significantly over its weight limitations. At the time of departure from Yakutsk Airport, the plane's total weight exceeded the maximum takeoff weight by 623 kilograms. Furthermore, upon arrival at Aldan Airport, the load was 550 kilograms above the maximum landing weight.

A primary contributing factor was the improper distribution of cargo, as over 400 kilograms of baggage had been loaded into the rear compartment. This excessive rear loading caused the center of gravity to shift outside of permissible limits.

Probable cause

The aircraft's center of gravity was outside of safe limits due to excessive weight and improper baggage loading in the rear compartment.
