The pilot tried to fly the airplane onto the runway to avoid floating. The airplane touched down firm and the pilot applied moderate braking, but the airplane did not decelerate normally. The airplane went off the end of the runway and collided with several Runway End Identifier Lights (REILs) and a tree. The airplane sustained substantial damage to the left and right wings. The pilot reported that he did not feel modulation in the anti-lock braking system (ABS) and felt that might have contributed to the accident. An examination of fault codes from the airplane’s diagnostic storage unit indicated no ABS malfunctions or failures. An airport employee reported that he saw the airplane unusually high on the final approach and during the landing the airplane floated or stayed in ground effect before it touched down beyond the midpoint of the runway. The airplane’s long touchdown was captured by an airport surveillance video, which is included in the report docket. ## Aircraft - Registration: [N686TM](https://openairdocs.org/deregistered/N686TM-2022-11-07), registration cancelled 2022-11-07, S/N 000221, built 2008 (OpenAirDocs) - Reported make and model: Eclipse EA 500 - Registry model: [Eclipse EA500](https://openairdocs.org/model/eclipse-ea500) (registry code 3350000) (OpenAirDocs) - Registry engine: [Pratt & Whitney Canada PW610F-A](https://openairdocs.org/engine/pratt-whitney-canada-pw610f-a) (registry code 52267, turbo-fan) (OpenAirDocs) - Category: Airplane - Serial number: 000221 - Year built: 2008 - Airframe hours: 1740 - Engines: Pratt & Whitney Canada PW610F-A 900 lbs thrust turbo fan - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Amicus Curire, LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, December 10, 2019 - Departed: MYF, San Diego, CA - Destination: Same as departure - Flight plan: IFR - Airport: LXV, Lake County, runway 16, 6,400 × 75 ft, asphalt - Equipment: Electronic primary flight display, Stall warning system, ADS-B, Auto-pilot, Electronic multifunction display ## Flight crew As NTSB recorded them.
