The defining event best describes what happened. - [Landing-landing roll: Sys/Comp malf/fail (non-power)](https://openairdocs.org/ntsb-events/330) (defining event); cases with it: [Newell Michael J LANCAIR ES, 1 case](https://openairdocs.org/ntsb-events/330/sequence.md?model=05621RE), [All aircraft, 994 cases](https://openairdocs.org/ntsb-events/330/sequence.md) ## Analysis The pilot of the airplane reported that, during the landing roll, the airplane was not slowing as expected. The pilot firmly applied braking action with no corresponding slowing action from the airplane. When he and his passenger saw the departure end of the runway approaching, they both applied as much brake pressure as possible without any effect. The airplane departed the runway and came to rest in a ditch, resulting in substantial damage to the engine mount. The airplane’s brake system was inspected by a mechanic who reported that the left side brake functioned, however it had a minor amount of air in the system and may not have had the same working pressure as the right-side brake. The pilot reported that there were no other preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N4949B](https://openairdocs.org/aircraft/N4949B), registered now, S/N ES-180, built 2006 (OpenAirDocs) - Reported make and model: NEWELL MICHAEL J LANCAIR ES - Registry model: [Newell Michael J LANCAIR ES](https://openairdocs.org/model/newell-michael-j-lancair-es) (registry code 05621RE) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane - Serial number: ES-180 - Year built: 2006 - Airframe hours: 868.4 - Engines: Continental TSIO-550-B2B 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Annual, April 17, 2020 - Departed: U42, West Valley, UT - Destination: Same as departure - Flight plan: VFR - Airport: 1L8, General Dick Stout Field Airport, runway 19, 3,282 × 60 ft, asphalt - Equipment: Electronic primary flight display, Stall warning system, ADS-B, Angle of attack indicator, Auto-pilot, Electronic multifunction display ## 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.
