A three-engine aircraft crashed into a mountain slope near Sefrou during a low-visibility night flight, resulting in the deaths of all sixteen occupants.

What happened

The incident occurred during nighttime operations under conditions of reduced visibility. The three-engine aircraft was flying at an altitude of 3,600 feet when it struck the slope of a mountain situated approximately 10 kilometers south of Sefrou. Recovery efforts located the wreckage several hours after the impact. Tragically, all 16 occupants aboard the aircraft perished in the accident.

Findings

Investigations indicated that the crew had committed a navigational error, causing the aircraft to deviate from its intended track prior to the collision. Additionally, the authorities determined that the altitude of 3,600 feet was insufficient for safe operation in that terrain.

Probable cause

The accident resulted from a navigational error by the crew and an insufficient flight altitude.
