Aircraft involved
Probable cause & findings
THE PILOT'S IMPROPER INFLIGHT PLANNING WHICH RESULTED IN THE FLIGHT'S ENCOUNTER WITH WAKE TURBULENCE FROM A LANDING HEAVY TRANSPORT.
Factual narrative
ACCORDING TO THE PILOT, HE WAS PERFORMING THE FOURTH TOUCH AND GO LANDING ON RUNWAY 19 LEFT. THE AIR TRAFFIC CONTROL TOWER CAUTIONED THE PILOT ABOUT POSSIBLE WAKE TURBULENCE FROM A BOEING 757 WHICH WAS LANDING JUST AHEAD OF THE AIRCRAFT ON RUNWAY 19 RIGHT. THE PILOT SAID HE WAS IN THE FLARE WHEN THE AIRCRAFT SUDDENLY ROLLED VIOLENTLY TO THE RIGHT. THE AIRCRAFT STRUCK THE RUNWAY ON THE RIGHT WING AND NOSE. A FIRE STARTED WHICH CONSUMED THE AIRCRAFT. THE WINDS WERE REPORTED BY THE TOWER AS 240 DEGREES AT 12 KNOTS. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
