Investigation Summary
The flight was the first leg of a journey from Paris to Bogota via Madrid and Caracas. During the night approach to Madrid, the crew initiated a descent before reaching the required navigational waypoint. The captain, who was highly experienced but reportedly fatigued, misidentified his position relative to the VOR/DME stations. Despite the GPWS sounding 'Whoop Whoop Pull Up' for several seconds, the crew did not take corrective action, believing they were at a safe altitude. The aircraft struck three hills; the first impact sheared off the right outboard engine and part of the wing, while the third impact resulted in the aircraft breaking apart and bursting into flames.
Final Conclusions
The Spanish Commission for the Investigation of Civil Aviation Accidents (CIAIAC) determined the cause was the pilot-in-command's failure to follow the published approach chart without having precisely determined the aircraft's position. Contributing factors included incorrect navigation by the crew, lack of teamwork (poor CRM), and the failure to respond to GPWS warnings.

Systems & Failure Modes
GPWS
Ground Proximity Warning System; it provided 15 seconds of warning which the crew ignored.
VOR/DME
VHF Omnidirectional Range and Distance Measuring Equipment used for navigation; the crew failed to correctly cross-check these instruments.
Interesting Facts
- 01The aircraft was a Boeing 747-200 leased from Scandinavian Airlines System (SAS).
- 02181 people died, while 11 passengers survived, all seated in the rear section.
- 03The captain had over 20,000 flight hours but had not slept significantly in the 24 hours prior to the flight.
- 04The crew misread the approach chart, confusing the 'CPL' and 'MA' waypoints.
- 05The crash occurred in darkness and light fog, limiting visual references.
Safety Actions & Advisories
CRM Training Mandates
The accident highlighted the need for standardized Crew Resource Management (CRM) to ensure co-pilots challenge captain errors.
GPWS Response Protocols
Aviation authorities reinforced that GPWS 'Pull Up' warnings must be treated as emergency commands requiring immediate action without verification.
