NTSB narrative
The flight instructor and student pilot departed for an instructional flight from an airport on an island en route back to their home airport on the mainland. A review of radar data indicated that the airplane took off with its transponder in the "off" position; therefore, no altitude information was available. The data indicated that, after taking off, the airplane flew north. The track ended 3 minutes later over open water about 5 miles north of the departure airport. After the airplane was reported missing, a search ensued. Although an oil slick consistent with drift models was present in this area, neither the airplane nor the occupants were found.
Four minutes before the airplane took off, the reported weather at the departure airport included 9 statute miles visibility and a broken cloud ceiling at 800 ft above ground level (agl); however, the remarks section reported that the ceiling varied between 600 and 1,000 ft agl. In addition, satellite imagery indicated that there was a thick marine layer just north of the airport.
Probable cause
Undetermined because the airplane was not located.

- 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.
