Contributing to the accident was a worn right main landing gear caliper pin and pressure plate hole. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Landing gear system: brake](https://openairdocs.org/ntsb-findings/01023242): Aircraft › Aircraft systems · Malfunction (probable cause); cases with it: [All aircraft, 297 cases](https://openairdocs.org/ntsb-findings/01023242/cases.md) - [Landing gear system: brake](https://openairdocs.org/ntsb-findings/01023242): Aircraft › Aircraft systems · Fatigue/wear/corrosion (probable cause); cases with it: [All aircraft, 297 cases](https://openairdocs.org/ntsb-findings/01023242/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight.

He stated that during landing, the right main wheel locked up and the airplane veered right. The pilot immediately released right brake pressure and increased left brake pressure, but the airplane continued to veer right off the right side of the runway and came to rest inverted in a grass area. The pilot subsequently examined the right brake under the supervision of a Federal Aviation Administration inspector. The brake piston tested satisfactorily, and the pilot could not duplicate a brake locking event. He noted that one of the two caliper pins and one of the two pressure plate holes were worn beyond specification. The pilot added that the wear could cause the pressure plate to cock, or foreign object debris to enter, and cause unintended braking. ## Aircraft - Registration: N665HM (not matched to a registry record) - Reported make and model: Vans RV8 (Undesignat) - Category: Airplane, amateur-built - Serial number: 82384 - Year built: 2011 - Airframe hours: 443.9 - Engines: Lycoming O-360-A1A 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, June 1, 2019, 34 hours before - Departed: HMP, Peachtree City, GA - Destination: HMP, Hampton, GA - Airport: HMP, Henry County Airport, runway 06, 5,500 × 75 ft, asphalt - Equipment: Angle of attack indicator, ADS-B, Handheld GPS, Electronic primary flight display, Auto-pilot ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
