He reported the approach was unstabilized, but he continued the landing resulting in a loss of control and subsequent hard landing. In addition, the pilot did not have access to the pitch trim control which was located on the left seat yoke which most likely contributed to the unstabilized approach. ## Factual narrative The pilot was flying the airplane from the right seat as he practiced touch and go landings. He reported he had difficulty maintaining a stabilized approach, but elected to continue with the landing. The airplane porpoised during the landing, and the nose gear collapsed resulting in substantial damage to the fuselage and carry-through wing spar. The pilot stated he was not very experienced in flying from the right seat and he did not have access to the pitch trim which was located on the left seat yoke. In addition, the he stated he should have performed a go-around instead of continuing the landing. ## Aircraft - Registration: [N39KB](https://openairdocs.org/aircraft/N39KB), registered now, S/N 080800028, built 2012 (OpenAirDocs) - Reported make and model: BOYD KENNETH C RANS S-19 - Registry model: [Boyd Kenneth C RANS S-19](https://openairdocs.org/model/boyd-kenneth-c-rans-s-19) (registry code 05630NY) (OpenAirDocs) - Registry engine: [Rotax 912ULS series](https://openairdocs.org/engine/rotax-912uls-series) (registry code 55572, 4 cycle) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 080800028 - Year built: 2012 - Airframe hours: 174 - Engines: Rotax 912ULS 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental light sport (Special) - Last inspection: Annual, May 10, 2016 - Departed: 3D2, Ephraim, WI - Destination: 3D2, Ephraim, WI - Airport: 3D2, Ephraim-Gibraltar, runway 32, 2,697 × 60 ft, asphalt ## Flight crew As NTSB recorded them.
