Aircraft involved

Probable cause & findings

THE PILOT'S IMPROPER IN-FLIGHT PLANNING/DECISION BY FAILING TO ALLOW ENOUGH TIME FOR THE ROTOR WASH TO DISSIPATE BEFORE ATTEMPTING THE APPROACH. THE WAKE TURBULENCE (ROTOR WASH) WAS A FACTOR IN THIS ACCIDENT.

Factual narrative

THE LOCAL CONTROLLER CLEARED THE FLIGHT FOR A STRAIGHT IN APPROACH TO RUNWAY 20 TO FOLLOW A LARGE HELICOPTER. THE CONTROLLER CAUTIONED THE PILOT OF POSSIBLE EXISTING WAKE TURBULENCE. WHILE NEARING THE THRESHOLD THE AIRPLANE ENCOUNTERED SOME TURBULENCE AND THE PILOT INITIATED A GO AROUND. DURING THE GO AROUND THE AIRPLANE ENCOUNTERED MORE SEVERE TURBULENCE AND COULD NOT CONTROL THE AIRPLANE. THE AIRPLANE STRUCK THE RUNWAY AND SKIDDED TO A STOP. THE PILOT REPORTED THAT THE SURFACE WINDS WERE FROM 180 DEGREES AT 10 KNOTS, GUSTING TO 15 KNOTS. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
