On August 30, 1993 at 1700 Alaska daylight time, a wheel equipped Piper, PA-18-150 airplane, N9016Y, registered to and operated by the Pilot-in-Command, intentionally ground looped during the landing roll at a private airstrip located near mile 102 of the Glenn Highway. The personal flight, operating under 14 CFR Part 91, last departed the airstrip for a local flight. No flight plan was filed and visual meteorological conditions prevailed. The airplane was substantially damaged and the Private Certificated Pilot in Command, the sole occupant, was not injured. According to the Pilot in Command upon landing he realized he had no brakes on the left side during the landing roll and as a result ground looped the airplane causing damage to both left wing spars, wing tip, aileron and elevator. The Pilot stated the airplane was equipped with a Cleveland Brake Wheel modification and the bolt heads pulled through the backing plate. The Pilot-in-Command did not submit a NTSB Form 6120.1/2 and the bolts and backing plate for the Cleveland Brake Wheel modification were not submitted for examination.
