Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

During a telephone interview, the pilot reported that, as he was landing, the airplane started to drift into nearby power lines. He initiated a go around; however, the left wing caught the power lines. The airplane impacted the ground and tumbled several times before it came to rest inverted. The fuselage was substantially damaged. The pilot reported that there were no mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. In a follow-up written statement, the pilot reported that during the landing on a dirt airstrip, the right-side brake failed due to a ruptured brake line. During the aborted landing, the airplane hit a power pole and wires. During the initial interview and report of no mechanical failures or malfunctions with the airplane, the airplane was released to the owner and the brake system was not examined.
