NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot was taxing to the run up area and collided with a Cessna 152 that was standing with engine running in the run up area. Before taxiing, the pilot completed a preflight inspection and a brake check, both of which showed no abnormalities with the airplane. He was taxiing at 1,000 rpm, which was about 13 miles per hour. Just before approaching the run up area, he began to reduce the throttle and applied brake pressure. The right brake did not respond. In an effort to avoid a propeller strike, the pilot decided to remain on the taxiway. He applied full left brake pressure and the airplane's left wing tip collided with this airplane's vertical stabilizer. The airplane continued to the left and departed the taxiway. The operator stated during recovery the airplane's brakes were tested. Both brakes appeared to be functioning properly. A repair shop that assessed the damage stated that after a thorough inspection, they could not find any malfunction of the braking system.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the pilot's use of an excessive taxi speed and too close of a spacing interval to the airplane ahead, which resulted in an on-ground collision when the preceding airplane abruptly stopped.
