This is not an accident investigation report.

Avianca Flight 011 took off from Paris-Charles de Gaulle at 22.25h for a flight to Bogota via Madrid. The crew intercepted the ILS ( for an approach to Runway 33) on the wrong track and continued to descend below MDA. This led to some problems with inserting the Madrid VOR coordiantes in the aircraft's INS (inertial navigation system), which caused the pilot to initiate a right turn short of the VOR beacon (the point were he should have made the turn). The right maingear and no.4 engine suddenly contacted a hill at an altitude of 2247ft and a speed of 142kts. Three seconds later the aircraft impacted a second hill at a sped of 135kts and a 4,9deg. nose-up attitude. Six seconds after contacting the 2nd hill, the aircraft (at 126kts) hit the ground with the right wing, which broke off. The Boeing cartwheeled and broke in five pieces and came to rest upside down. PROBABLE CAUSE: "The pilot-in-cormnand, without having any precise knowledge of his position, set out to intercept the ILS on an incorrect track without initiating the published instrument approach manoeuvre; in so doing he descended below all; the area safety minima until he collided with the ground. Contributory factors were: a) Inaccurate navigation by the crew, which placed them in an incorrect position for initiating the approach manoeuvre.; b) Failure of the crew to take corrective action in accordance with the operating instructions of the ground proximity warning system.; c) Deficient teamwork on the flight deck.; d) Imprecise position information supplied to the aircraft by APP.; e) The APP controller, in failing to inform the aircraft that radar service had terminated, did not maintain a proper watch on the radar scope."
