Incident Details
During a setup for a practice stall, the solo student pilot retarded the throttle, raised the nose slightly, and applied carburetor heat. Believing the airspeed was dropping too quickly, the pilot then reapplied full power. At this point, the engine RPM dropped to 5 or 500.
Pilot Actions
While setting up for a forced landing, the pilot pumped the throttle, changed the mixture, checked the fuel selector, and removed the carburetor heat. Despite these actions, the engine would not recover.
Forced Landing and Outcome
The aircraft nosed over onto its back during the forced landing.
Post-Accident Investigation
The post-accident investigation revealed that the engine operated normally, along with the magnetos and the carburetor heat.
