NTSB narrative

The noncertificated pilot reported that the airplane departed the runway and that, during the initial climb, it could not gain altitude. He attempted to return to the runway, but the airplane landed hard in an orchard. The pilot later reported that, before takeoff, a large helicopter was hovering close to the runway and that he believed the his airplane "entered…[the helicopter's] rotor wash and lost lift." The airplane sustained substantial damage to the wings. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable cause

The noncertificated pilot’s decision to take off through a large helicopter’s rotor wash, which resulted in his inability to gain altitude during takeoff.

  • 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: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 2020-04-21.
  • API snapshot SHA-256: f4024a860b235435b8f51868a9381ef17ab1a30060645803a65c33566c9b4e05; retrieved 2026-09-16T11:28:59.825Z.
