Probable cause
The partial failure of the normal brake system, the misjudging of the proper touchdown point and the attempted go around. Factor was the rough and uneven landing area.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot landed approximately 125 feet past the threshold of a 700 foot long airstrip. He began to apply brake pressure with increasing pressure. He stated that when he was applying hard brake pressure he lost all pressure in the right brake. The pilot stated he was not going to be able to stop and he attempted a go around. The airplane did not get airborne before running off the end of the airstrip and overturning in fish creek. Examination of the brake calipers showed that the old drum brake caliper had fractured through the chamber causing the fluid to leak out.
