NTSB narrative

THE CFI REPORTED THAT HE REDUCED PWR TO NEAR IDLE WITH THE THROTTLE, TO HAVE HIS STUDENT PRACTICE A SIMULATED FORCED LDG. THE ENGINE SUBSEQUENTLY LOST PWR COMPLETELY AT ABOUT 400-500 FT AGL WHEN HE ATTEMPTED TO ADD PWR BACK SO THAT THE STUDENT COULD INITIATE A GO-AROUND. SUBSEQUENT EFFORTS TO REGAIN PWR WERE UNSUCCESSFUL, AND A FORCED LDG WAS MADE IN A FIELD. THE CFI NOTED THAT HE HAD INCREASED THE PWR MOMENTARILY SEVERAL TIMES DURING DESCENT TO 'CLEAR' THE ENGINE, AND THAT HE WAS 'SLOWLY' OPENING THE THROTTLE WHEN THE ENGINE LOST PWR. POST-ACCIDENT EXAMINATION OF THE AIRPLANE AND ENGINE BY THE FAA REVEALED NO EVIDENCE OF ANY PRE-EXISTING MALFUNCTION OR FAILURE.

  • 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.
