NTSB narrative
AFTER DERARTING THE ARPT AND FLYING ABOUT 75 FT AGL, THE PLT ADDED POWER AND ATTEMPTED TO CLIMB. THERE WAS A POWER HESITATION AND THE ACFT DID NOT CLEAR TREES IN IT'S PATH. THE ACFT STRUCK TREES AND DESCENDED TO GROUND IMPACT. THE PLT STATED THAT HE THOUGHT THAT THERE HAD BEEN WATER IN THE FUEL AND THE ACFT HAD BEEN STORED WITHOUT THE FUEL TANKS BEING TOPPED OFF.

- 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 1986-06-11.
