Incident Overview

Description
Some 6 minutes after takeoff from Dsseldorf the no. 1 propeller went into reverse. The prop could not be feathered, so the pilot-in-command decided to return to the airport. The approach had to be abandoned due to low clouds and control problems. A missed approach procedure was carried out, but altitude was lost. High tension wires ahead forced the captain to extend the flaps to 20deg to lift over them. This evasive manoeuvre worked, but the aircraft then stalled and crashed. PROBABLE CAUSE: “The accident was due to a) the propeller of the left-hand engine going into brake position during climb. The technical reason for this occurrence so far has not been found; b) the weather which made the approach rather difficult. In good weather conditions the landing would probably have been successful.”
Primary Cause
Propeller malfunction during climb, exacerbated by challenging weather conditions.Propeller malfunction during climb, exacerbated by challenging weather conditions.Share on:
