An aircraft stalled during a night instrument landing system approach due to diminished airspeed, resulting in a collision with terrain short of the runway.

What happened

The flight was conducted under night instrument meteorological conditions while executing an instrument landing system (ILS) approach. During this phase of flight, the pilot allowed the aircraft's airspeed to decrease significantly. This reduction in speed resulted in the airplane entering a stall condition.

Before the pilot could successfully regain control of the aircraft, it collided with the terrain located short of the runway. There were no reported mechanical failures or malfunctions involving the airplane or airport equipment at the time of the accident.

The investigation

The investigation focused on the operational factors leading to the loss of control. Examination of the event revealed that the primary issue was the stall caused by insufficient airspeed during the approach phase. No mechanical issues were identified as contributing factors.

Probable cause

The pilot's failure to maintain adequate airspeed during an ILS approach, which resulted in a stall and subsequent collision with terrain short of the runway.
