A BAe-125-800A airplane, N469RJ, was substantially damaged when it was involved in an accident upon landing on runway 33 at Coleman A Young Municipal Airport (KDET), Detroit, Michigan, USA. The two pilots onboard were not injured.

The crew was conducting an instrument landing system (ILS) approach. The air traffic controller at the departure airport advised them of the icing conditions present so the crew turned on the anti-ice system. The airplane did not have any airspeed oscillations during the approach. The flying pilot reported that the right wing "dropped" and a stall occurred as they approached the runway. He stated, "Although flight crew selected the correct Vref speed for the aircraft weight, they failed to add 10 kts for the 'operation in icing conditions' statement, per the aircraft checklist."
The stick shaker should have alerted the crew of the approaching stall. However, the flying pilot said that there was no shaker activation during the flight. The non-flying pilot felt the shaker was activated after the airplane came to rest.
The reason for the lack of a stick shaker warning was not determined during the investigation. However, the cockpit voice recording confirmed the pilots’ statements. The accident is consistent with the airplane stalling on approach due to ice buildup, and the accident likely would not have occurred had the pilot’s flown the higher approach speed recommended for flight in icing conditions.

Probable Cause:

Probable Cause: "The pilots’ failure to increase approach speed as recommended for flight in icing conditions, which resulted in an aerodynamic stall and subsequent impact with terrain. Contributing to the accident was the failure of the stall warning system to advise the crew of the approaching stall."
