14 CFR Part 91: General Aviation
Accident occurred Saturday, April 18, 2015 in Independence, IA
Probable Cause Approval Date: 05/13/2015
Aircraft: CESSNA 195A, registration: N1558D
Injuries: 4 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot was landing on runway 36. After touching down, the airplane began a slow right turn. The pilot attempted to correct by applying left rudder and light braking, but the airplane departed the right side of the runway, and was substantially damaged. The wind was from 100 degrees at 14 knots, gusting to 18 knots, which resulted in a 13.7 to 17.7 knot crosswind component, and a 2.5 to 3.2 knot tailwind component. Most light general aviation airplanes are limited to a direct crosswind component of 15 knots.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's attempt to land in strong crosswind conditions, resulting in his on-ground loss of control. Contributing to the accident was the crosswind that exceeded the crosswind limits of the airplane.





The pilot configured the airplane for a crosswind landing on runway 36 using cross controlled inputs. He flared and touched down in a 3-point attitude. After rolling 150 to 200 feet down the runway, the airplane began a slow right turn. He attempted to correct by applying left rudder and light braking, but the airplane departed the right side of the runway. The left main landing gear was torn off, and the left wing was bent upward after striking the ground.

At the time of the accident, the wind was from 100 degrees at 14 knots, gusting to 18 knots. According to AeroPlanner.com "Wind Calculator and Wind Speed Measurement," these conditions would result in a 13.7 to 17.7 knot crosswind component, and a 2.5 to 3.2 knot tailwind component. In the 1950s, maximum crosswind components were not published by airframe manufacturers, but today light general aviation airplanes are limited to a direct crosswind component of 15 knots.
