Accident Sequence
Following takeoff from runway 24, the aircraft executed a VALKO departure as cleared by Air Traffic Control (ATC). During climb, passing flight level 165 (FL165), the Master Warning was triggered by the right engine oil pressure Central Warning Panel (CWP) light. The captain slowly retarded the right hand power lever to flight idle and called for the emergency checklist. After completion of the emergency checklist procedure, the right hand engine oil pressure CWP light remained illuminated, and the captain decided to return to Amsterdam. The right hand engine remained in flight idle for the remainder of the flight.
Emergency Response and Return
While returning to Amsterdam, the flight was radar vectored by ATC for an Instrument Landing System (ILS) approach on runway 06. After passing approximately 200 feet height, the aircraft became displaced to the right of the runway, and a go-around was initiated.
Loss of Control and Impact
During the go-around, control of the aircraft was lost. At 12:46 UTC, the aircraft hit the ground in a slight nose low attitude with approximately 80° bank to the right, approximately 560 meters right from the runway 06 centerline, just outside the airport. Two passengers and the captain died in the accident; eight passengers and the first officer were seriously injured.
Probable Cause and Contributing Factors
Probable cause: Inadequate use of the flight controls during an asymmetric go around resulting in loss of control. The following contributing factors were reported: - Insufficient understanding of the flight crew of the SAAB 340B engine oil system, - Lack of awareness of the consequences of an aircraft configuration with one engine in flight idle, - Poor Crew Resource Management.
