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. ## Aircraft - Registration: [N47149](https://openairdocs.org/deregistered/N47149-2018-03-05), registration cancelled 2018-03-05, S/N 7115-J521, built 1978 (OpenAirDocs) - Reported make and model: Wilderoder GREAT LAKES 2TIA (GREAT LAKE) - Registry model: [Wilderoder GREAT LAKES 2TIA](https://openairdocs.org/model/wilderoder-great-lakes-2tia) (registry code 3910233) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 7115-J521 - Airframe hours: 671 - Engines: Lycoming O-320 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Dean J.
