Aircraft Accident/Incident Report

Tucson, Arizona 85734
Thursday, July 18, 2002 9:49 MST

NTSB Narrative Summary Released at Completion of Accident

On short final approach between 50 and 75 feet above the ground, the pilot encountered wake turbulence from a MD80, which had just landed. During the wake turbulence encounter, the accident airplane suddenly rolled into a near vertical left bank, control was lost, and it crashed about 340 feet from the runway. While in the traffic pattern, the pilot had observed the approaching MD80. Air traffic control personnel advised the pilot that the local wind was from 060 degrees, at 7 knots, and the controller twice cautioned the pilot regarding wake turbulence. At 0947:24, the MD80 was about 1 mile from landing on a visual approach to runway 11L and it landed at 0948:29 . The accident pilot crashed at 0949:28, approaching parallel runway 11R. Tucson International Airport operations personnel reported that the impact site was about 340 feet short of the runway.

NTSB Probable Cause Narrative

The pilot's loss of control resulting from his improperly planned approach and an inadvertent encounter with wake turbulence.
