Probable cause
The pilot's failure to maintain flying speed while at an altitude that did not provide adequate terrain clearance for a safe stall recovery.
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
A witness observed the Cessna 170A make a low pass over him. He said it stalled and entered a nose-down attitude with the wings wagging. He said that the airplane had leveled just before impact. The aircraft was destroyed by ground impact and the two occupants sustained serious injuries.
