Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

As the airplane departed from the runway, the pilot deployed the tow hook and climbed to 150 feet. The pilot then "sidestepped" to the right of the runway to pick up the banner, which was set up on the grass about half way down the runway. The pilot "crossed the pickup rope at too slow of an airspeed, approximately 55-60 MPH, versus a normal target speed of approximately 70 to 80 MPH." The pilot then pitched the airplane upward, catching the rope with the tow hook, and soon realized that "there were problems in climbing out." After about 5 seconds, the pilot considered releasing the banner, but decided against the idea, due to releasing the banner on a crossing runway. After clearing the runway area, the pilot released the banner, about 100 feet above the ground, "and in an incipient stall attitude." Unable to climb, and not enough altitude to gain any additional airspeed, the pilot began to raise and lower the nose of the airplane to avoid a stall. As the pilot maneuvered the airplane to an open parking lot for a forced landing, the airplane struck power lines and impacted a utility pole, shearing off the right wing. The airplane descended to the ground, and came to rest upright.

NTSB Probable Cause Narrative

The pilot's failure to maintain airspeed while picking up a banner, and subsequent delay in releasing the banner, resulting in a stall/mush.
