Total loss of engine power (non-mechanical)
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
Stall
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative

WITNESSES REPORTED THE AIRPLANE WAS IN A WIDE SPIRAL, THEN IT SUDDENLY ENTERED A DIVE & CRASHED. ONE WITNESS, WHO WAS OUTSIDE & AWAY FROM STRUCTURES, REPORTED THE ENGINE WAS SPUTTERING, JUST BEFORE IMPACT. THE DUAL STUDENT RETAINED ONLY A FRAGMENTED MEMORY OF THE DAY OF THE ACDNT. HOWEVER, HE REMEMBERED THAT THE INSTRUCTOR TOOK CONTROL OF THE AIRPLANE, WHEN THE ENGINE BEGAN TO SPUTTER DURING A POWER APPLICATION. ALSO, HE REPORTED THAT CARBURETOR HEAT HAD BEEN USED PRIOR TO APPLICATION OF POWER. A REVIEW OF THE INSTRUCTOR & STUDENT LOGBOOKS SHOWED THAT THERE HAD BEEN INSTRUCTION IN EMERGENCY PROCEDURES DURING THE PREVIOUS PERIOD OF INSTRUCTION. NO PREIMPACT PART FAILURE WAS FOUND DURING THE INVESTIGATION. THE ENGINE WAS MOUNTED ON A TEST STAND & OPERATED TO 1000 RPM. THE TEMPERATURE & DEW POINT WERE REPORTED TO BE 54 & 47 DEG, RESPECTIVELY. ACCORDING TO ICING PROBABILITY CHARTS, CONDITIONS WERE CONDUCIVE TO SERIOUS ICING AT CRUISE POWER.

Probable cause

IMPROPER USE OF CARBURETOR HEAT BY THE DUAL STUDENT, CARBURETOR ICE, INADEQUATE SUPERVISION TO CORRECT THE SITUATION BY THE INSTRUCTOR PILOT (CFI), AND FAILURE OF THE CFI TO MAINTAIN ADEQUATE AIRSPEED, WHICH RESULTED IN A STALL. CARBURETOR ICING CONDITION WAS A RELATED FACTOR.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
