NTSB narrative

The flight instructor was demonstrating agricultural, low-altitude operations to the pilot. The instructor reported that he noticed a loss of engine power when making a turn; the airplane then descended and impacted the tops of several trees. The airplane fell nose first through the thick wooded canopy, coming to rest in the trees in a mostly nose-down attitude. The pilot reported that the instructor had been flying the airplane slowly while in wingover turns and that the stall light would regularly flicker on and off during the climbing turns. He added that the instructor did not increase the engine power setting before impact and that the airspeed was low immediately before the airplane impacted the trees.

The instructor did not report using carburetor heat during his low-altitude operations but did report that he was operating at a reduced power setting. An examination of the airplane showed no preimpact mechanical malfunctions or failures that would have precluded normal operation. Although a carburetor icing probability chart indicated that an airplane operating in the ambient conditions at the time of the accident could expect a risk of carburetor icing while at cruise power and a serious risk of carburetor icing while at glide power, it is more likely that the airplane entered into an aerodynamic stall at an altitude too low for the pilot to recover based on the account given by the pilot.

Probable cause

The flight instructor's failure to maintain adequate airspeed, which resulted in an aerodynamic stall and subsequent impact with trees.

  • 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.
