No fatalities

1995-11-01: Antonov AN-24 (UN-47710) — Kazakhstan Airlines - Air Kazakhstan - Kazair — Shymkent, Kazakhstan

Shymkent, KazakhstanLanding (descent or approach)

On November 1, 1995, an Antonov AN-24 (registration UN-47710) operated by Kazakhstan Airlines - Air Kazakhstan - Kazair was involved in an aviation accident near Shymkent, Kazakhstan during landing or approach. No fatalities were reported. Investigators recorded the probable cause as: A lack of effective coordination and miscommunication between the pilot and flight engineer led to the unintended shutdown of all engines during an engine failure simulation. 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.

A training flight at Shymkent Airport resulted in a ground impact after the incorrect shutdown of both engines during a simulated failure procedure.

What happened

During a routine local training session near Shymkent Airport, an incident occurred involving an aircraft undergoing engine failure simulations. While the crew was performing maneuvers at an altitude of approximately 300 meters during the approach phase, the instructor intentionally deactivated one engine to mimic a mechanical malfunction.

Following this action, the pilot-in-command issued a command for maximum power from the remaining operational engine. However, due to a misunderstanding of these instructions, the flight engineer proceeded to shut down the second engine. This error caused the aircraft to lose both propulsion and necessary airspeed. As a result, the plane descended rapidly and impacted the terrain 1,100 meters before reaching the runway threshold, experiencing a vertical acceleration of 2.6 g.

Findings

The accident resulted in four injuries among the crew members, though no fatalities were reported. The aircraft sustained damage that rendered it a total loss. Investigations concluded that the primary factor was poor communication between the crew members during the simulated emergency procedure.

Probable cause

A lack of effective coordination and miscommunication between the pilot and flight engineer led to the unintended shutdown of all engines during an engine failure simulation.
