A contributing factor was the prevailing wind. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Performance/control parameters: landing flare](https://openairdocs.org/ntsb-findings/01062041): Aircraft › Aircraft oper/perf/capability · Incorrect use/operation (probable cause); cases with it: [Jihlavan Airplanes Sro KP5, 1 case](https://openairdocs.org/ntsb-findings/01062041/cases.md?model=060001I), [All aircraft, 1,285 cases](https://openairdocs.org/ntsb-findings/01062041/cases.md) - [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Jihlavan Airplanes Sro KP5, 2 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md?model=060001I), [All aircraft, 9,295 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md) - [Wind: crosswind](https://openairdocs.org/ntsb-findings/03034040): Environmental issues › Conditions/weather/phenomena · Not specified (probable cause); cases with it: [Jihlavan Airplanes Sro KP5, 1 case](https://openairdocs.org/ntsb-findings/03034040/cases.md?model=060001I), [All aircraft, 1,008 cases](https://openairdocs.org/ntsb-findings/03034040/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Landing-flare/touchdown: Abnormal runway contact](https://openairdocs.org/ntsb-events/090) (defining event); cases with it: [Jihlavan Airplanes Sro KP5, 1 case](https://openairdocs.org/ntsb-events/090/sequence.md?model=060001I), [All aircraft, 1,506 cases](https://openairdocs.org/ntsb-events/090/sequence.md) ## Analysis The 475-hour private pilot approached runway 19 at 70 mph and selected "one notch" of flaps. The pilot stated that the wind was light and variable, but that the airplane still had a wind correction angle to the runway. The pilot stated he still had the "crab [angle]" (to the runway) still in, when he flared too high. He added that the airplane's speed was about 60 mph. The airplane's right wing dropped as he pushed the control stick forward and added engine power; however, the airplane hit the runway at a right angle of about 15-20 degrees. The airplane's nose gear collapsed and the airplane slid for 50-60 feet, before coming to rest in the upright position. Examination of the airplane revealed that the nose wheel had separated from the aircraft and the right wing had sustained substantial damage. ## Factual narrative The 475-hour private pilot approached runway 19 at 70 mph and selected "one notch" of flaps.

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.
