What happened
While performing a transition from a DME arc to the ILS final approach course, the aircraft descended into the terrain prematurely. The incident occurred under challenging environmental conditions characterized by dark night visibility, fog, and low cloud ceilings. During this phase of flight, the aircraft's descent led to a collision with the ground.
All three occupants on board sustained injuries during the impact, with two individuals suffering serious harm.
Findings
Investigations into the accident revealed that there were no signs of mechanical failure or malfunction within the aircraft prior to the impact. Additionally, there was no evidence to suggest that the pilot had become incapacitated. While the specific reason for the uncontrolled descent could not be determined, investigators identified the premature descent by the pilot in command as a primary factor in the collision with the terrain.
