NTSB narrative
The pilot accepted an intersection departure and waived the wake turbulence holding time. A Boeing 737-300 departed ahead of him, and according to pilot, the Boeing's nosewheel lifted off the runway just as it passed him. The pilot also noted that the Boeing and its exhaust smoke drifted to the left of the runway's centerline. A wake turbulence advisory and takeoff clearance were issued by the tower controller and acknowledged by the pilot. The pilot initiated the takeoff, and after liftoff, the left wing dropped. It contacted the runway, and the airplane rolled inverted. The airplane then slid off the left side of the runway and a post-crash fire developed.
Probable cause
The pilot's improper decision to waive the wake turbulence hold time, and his subsequent loss of control when wake vortex turbulence was encountered.

- 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, coordinates. 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.
