The second approach was normal. During the landing flare, the airplane floated longer than usual and drifted towards the right side of the runway in crosswind conditions. As the airplane touched down, the right main wheel encountered a trench and continued to traverse up a berm. Upon reaching the top of the berm, the airplane slid sideways until it came to a rest. The pilot reported no preimpact mechanical failures or malfunctions. The nearest weather reporting station located 12 miles southeast of the accident airport reported at the time of the accident wind was from 330 degrees at 9 knots. ## Factual narrative The pilot reported that after a cross country flight, while on final approach he realized the airplane was not centered on the runway and he executed a go around. The second approach was normal; during the landing flare the airplane “floated longer than usual” and drifted towards the right side of the runway. As the airplane touched down, the right main wheel fell into a trench and continued to traverse up a berm. Upon reaching the top, the airplane slid sideways along the berm until it came to a rest, substantially damaging the left wing and fuselage. The pilot reported no mechanical failures or malfunctions prior to the accident. The nearest weather reporting station located 12 miles southeast of the accident airport reported at the time of the accident wind was from 330 degrees at 9 knots. ## Aircraft - Registration: [N948DW](https://openairdocs.org/deregistered/N948DW-2017-05-19), registration cancelled 2017-05-19, S/N 701DW-1, built 2007 (OpenAirDocs) - Reported make and model: WILDE DANIEL L ZENITH 701 - Registry model: [Wilde Daniel L ZENITH 701](https://openairdocs.org/model/wilde-daniel-l-zenith-701) (registry code 0590217) (OpenAirDocs) - Registry engine: [Rotax 912S series](https://openairdocs.org/engine/rotax-912s-series) (registry code 55570, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 701DW-1 - Airframe hours: 127 - Engines: ROTAX 912S 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Wilde Daniel L - Registered owner: Wilde Daniel L - Airworthiness certificate: Special, Experimental light sport (Special) - Last inspection: Annual, December 4, 2009, 30 hours before - Departed: ISN, Los Banos, CA - Destination: N/A, Turlock, CA - Airport: N/A, Personal Airstrip, runway 36, 900 × 20 ft, grass/turf ## 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.
