NTSB narrative
The owner reportedly last saw the airplane on October 14, 1999; no one had permission to fly it. He flew commercially to Michigan from Florida, that day which was 1 day earlier than scheduled due to adverse weather. On October 16, 1999, a Martin County Sheriff Department Detective was called to the airport and observed the crashed airplane at 1030 hours; no damage to the hangar doors was noted. The owner stated that his medical is being reviewed by the FAA in Oklahoma City, Oklahoma. The owner's brother paid for hangar rental from September 22, to be vacated on October 15. No arrangements were made beyond October 15. The owner and owner's brother refused to take polygraph tests when requested by representatives of the Martin County Sheriff Dept. On October 14, 1999, one ELT signal was received by one ground station. The ground station calculated the source of the ELT signal to be located from one of two locations, one of which was determined to be located 34 nautical miles and 046 degrees from the Indiantown Airport. The aircraft keys were found in the back seat. The ELT was in the 'off' position, and out of the bracket.
Probable cause

- 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.
