Circumstances:
Following an uneventful flight from Saint Joseph, Missouri, the crew started the descent to Detroit-Willow Run Airport. After a wrong approach configuration, the crew misjudged distance and speed during the last segment, causing the aircraft to land too far down the runway. After touchdown, the airplane was unable to stop within the remaining distance and the captain decided to initiate a go-around manoeuvre but this was too late. The airplane overran, struck the localizer antenna then crashed on the ILS building. Both pilots were killed while the passenger was seriously injured.
Probable cause:
Improper operation of flight controls on part of the crew who misjudged distance and speed and delayed in initiating a go-around manoeuvre. The following factors were reported:
- The crew failed to stow spoilers on go-around.
