NTSB narrative

The pilot was conducting a cross country instrument flight rules flight. The airplane was deviating around thunderstorm activity, and was cleared to it's destination airport, when radar contact was lost. A witness reported hearing an airplane overhead; however, he could not see the airplane due to haze and clouds. He described the engine noise as "revving in a cycling pattern." Within 10 seconds, he observed an airplane exit the clouds in a nose down spiral, with one wing missing. The airplane impacted Lake Erie nose first and sank. Examination of the right wing main spar revealed fractures consistent with an overstress separation and aft and upward loading. The pilot obtained a weather briefing prior to the flight. At the time of the briefing, there were no current or forecasted thunderstorms around the pilot's destination airport. There were also no convective SIGMETs valid for the area where the accident occurred. Review of weather radar around the time of the accident revealed two very strong thunderstorm cells over the western portion of New York, along Lake Erie, moving northeast. The airplane disappeared from radar, as it transitioned through the northern edge of one of the echoes in reflectivity values near 25 dBZ or very light intensity echoes. The geo-synchronous weather satellite-12 (GOES-12) visible image depicted a large band of clouds extending over Lake Erie, and New York. Several Cumulonimbus clouds were located immediately south of the accident site.

Probable cause

The pilot's loss of aircraft control and the subsequent overstress and separation of the wing during an encounter with convection induced turbulence.

  • 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.
