Probable cause
The pilot’s failure to detect the inadvertent deployment of the spoilers, which resulted in a prolonged, excessive descent rate. Contributing to the accident was the pilot’s decision to conduct a downwind approach versus a straight in approach to the diversionary airport, which resulted in an off-airport landing.
