Probable cause

The pilot's failure to check the brake hydraulic fluid reservoir prior to flight resulting in a low fluid level going undetected and failure of the brakes during landing rollout, which resulted in the aircraft overrunning the runway, colliding with a fence, and nosing over.

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

During landing rollout the brakes did not work. The aircraft overran the runway, collided with a fence, and nosed over. Postcrash examination of the brake system showed the hydraulic fluid reservoir was empty and there was no evidence of postcrash leakage of fluid from the reservoir.

Factual narrative

On July 31, 1999, about 0750 central daylight time, a Wilderoder Great Lakes 2TIA, N47149, registered to an individual, overran the runway, collided with a fence, and nosed over while landing at Coastal Airport, Pensacola, Florida, while on a Title 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the private-rated pilot was not injured. The flight originated from Pensacola, Florida, the same day, about 0730.

The pilot stated that during landing roll, he felt no deceleration as he applied the brakes. He released the brakes and applied them again, but the aircraft did not decelerate. The aircraft overran the runway, collided with a fence, and nosed over. Postcrash examination of the aircraft showed the brake hydraulic fluid reservoir was empty and there was no evidence of postcrash fluid leakage from the reservoir.
