Synopsis
The following are extracts from the Accident report published by the Luxembourg Ministry of Transport:
Conclusions
…7. RVR was below approved company minima during the initial and the intermediate approach,
8. During the approach, the crew did not comply with the operator’s procedures,
9. Despite the fact that the meteorological conditions for a CAT II approach prevailed, none of the required prerequisites, to perform a CAT II approach, were taken by the crew.
10. The captain resumed the final approach after having announced a go-around, without co-pilot’s reaction,
11. In order to achieve this goal, the crew performed several non-standard actions, amongst which the prohibited positioning of the power levers beyond flight idle. The AFM contained a limitation that prohibits the selection of ground idle in flight.
12. The selection of the landing gear down, triggered the deactivation of the second safety device (solenoid secondary stops) which was a possible malfunction identified by the manufacturer.…
Causes
The initial cause of the accident was the acceptance by the crew of the approach clearance although they were not prepared to it, namely the absence of preparation of a go-around. It led the crew to perform a series of improvised actions that ended in the prohibited override of the primary stop on the power levers.
