NTSB narrative

The outboard 1/3 of the aircraft's left wing was deformed upward about 5 degrees with respect to the inboard section during an encounter with wake turbulence while on downwind leg for landing. The upper wing skins of both wings exhibited compression buckling, and the mass balance weights on both ailerons were separated and fell from the aircraft. The pilot reported that the flight was unremarkable until, while downwind for landing, there was an instantaneous jolt of sudden severe turbulence that ended before he could take any action. Data obtained from the airport noise abatement office showed that 2 minutes 23 seconds prior to the encounter, a heavy transport aircraft passed over the location on an ILS approach to another airport 6 miles away; the transport airplane was about 500 feet higher than the accident airplane as it crossed the location. The air traffic control tower at the airport where the accident occurred made a wake turbulence cautionary broadcast to all aircraft 30 seconds prior to when the accident aircraft first contacted the tower for landing. The cautionary broadcast was not repeated.

Probable cause

The pilot's encounter with unknown and unanticipated wake turbulence from a heavy transport aircraft, which was landing at another airport. A factor in the accident was the tower controller's failure to repeat a previously broadcast wake turbulence cautionary advisory when the aircraft later checked in on tower frequency.

  • 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 1999-11-13.
