Subsequently, the airplane overran the runway and struck a fence about 20 feet beyond the end of the runway, which resulted in substantial damage to the firewall. The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that while landing on a wet grass runway, he touched down long, skidded about 200 feet, and was unable to slow the airplane. Subsequently, the airplane overran the runway and struck a fence about 20 feet beyond the end of the runway, which resulted in substantial damage to the firewall. The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation. After multiple requests by the National Transportation Safety Board (NTSB) investigator-in-charge, the pilot failed to submit the NTSB Form 6120.1 Pilot/ Operator Aircraft Accident/ Incident Report. ## Aircraft - Registration: [N6453U](https://openairdocs.org/deregistered/N6453U-2021-03-06), registration cancelled 2021-03-06, S/N 2200 (OpenAirDocs) - Reported make and model: MOONEY M20C - Registry model: [Mooney M20C](https://openairdocs.org/model/mooney-m20c) (registry code 5870208) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 2200 - Engines: Lycoming O&VO-360 reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Departed: C01, WILLIAMSTOWN, NJ - Destination: C01, Williamstown, NJ - Flight plan: Unknown - Airport: C01, Southern Cross, runway 09, 2,400 × 80 ft, grass/turf - Equipment: Unknown ## Flight crew As NTSB recorded them.
