Narrative:The Sonatrach company chartered one of Tassili Airlines' Beechcraft 1900D planes to fly two employees from the oil fields near the Algerian Sahara town of Hassi R'Mel to Ghardaïa. The copilot was Pilot Flying. The Beech took off at 20:30 and arrived near Ghardaïa fourteen minutes later.
At 20:44 the flight was cleared for a right hand circuit in preparation for an approach to runway 30. At that moment a Boeing 727 was on long finals. The copilot stated that he intended to carry out an NDB/ILS approach to runway 30. The captain however preferred a visual approach. The copilot carried out the captain's course and descent instructions with hesitation. At 20:57, the EGPWS alarm sounded. Power was added and a climb was initiated from a lowest altitude of 240 feet above ground level.
The captain then took over control and assumed the role of Pilot Flying. The airplane manoeuvred south of the airport until 21:01 when the copilot saw the runway. The captain rolled left to -57° and pitched down to -18.9° in order to steer the airplane towards the runway. Again the EGPWS sounded but the descent continued until the airplane impacted the ground and broke up.
The five occupants survived the impact, but the co-pilot died a day later of his injuries.
Probable Cause:Causes of the accident (translated from French):
The Commission believes that the accident can be explained by a series of several causes which, taken separately, would not lead to an accident.
The causes are related to:
1 - the lack of rigor in the approach and landing phase evidenced by a failure to follow standard operating procedures, including the arrival checklist.
2 - the failure to strictly comply with the holding, approach and landing procedures in force for the aerodrome of Ghardaïa.
3 - the fact that the captain seemed occupied by the visual search maneuvers that put him temporarily out of the control loop.
He was so focused on the visual search for the runway and abandoned the monitoring of parameters that are critical for the safety of the flight. This concentration completely disoriented him.
4 - the fact that the crew did not respond appropriately to different alarms that occurred, indicating a lack of control in the operation of the aircraft in that kind of situation.
Lack of control was apparently due to his lack of training on this aircraft type.
5 - The activities in the southern part of Algeria may cause a certain routine that can promote the tendency to conduct visual approaches.
It seems, indeed, that the crew is more experienced in visual flights.
6 - A lack of coordination and communication between the crew members flying together for the first time.
