Probable cause
The pilot's failure in maintaining airspeed and not identifying the stall during the descent for landing.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot stated that he allowed the airplane to fly so slow that he stalled it during the descent for landing and was unable to recover due to a lack of sufficient altitude.
