On 25 February 2009, a Boeing 737-800 crew making an automatic ILS approach to Amsterdam with the operating First Officer undergoing early stage line training and a Safety Pilot occupying the supernumerary crew seat lost control after a malfunction of one of the radio altimeters, which resulted in the autothrottle unexpectedly setting idle thrust. The resultant progressive pitch increase went unnoticed by any of the pilots until an EGPWS ‘PULL UP’ Warning occurred. A delayed response then prevented recovery and terrain impact followed with the aircraft wrecked but with no post crash fire and only nine fatalities amongst the 135 occupants.

Editor's Note:
The Final Report of this very thorough Investigation is not presented in the standard format envisaged by Annex 13 at that time or since or in almost any way recognisably similar to this. Despite the relatively short main body of the report, factual information which would normally be expected to appear in the main body of the report appears in some of the 22 Appendices. There is also no meaningful summary for accident prevention purposes of the relative significance of the many contributory factors identified.
Investigation
An Investigation into the Accident was carried out by the Dutch Safety Board. All relevant data was recovered from the FDR and two hour CVR.
