NTSB Identification: CEN09IA153
14 CFR Part 91: General Aviation
Incident occurred Wednesday, February 04, 2009 in Aspen, CO
Probable Cause Approval Date: 03/23/2010
Aircraft: NEW PIPER AIRCRAFT INC PA-46-500T, registration: N535JR
Injuries: 2 Uninjured.

NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.

The private pilot and passenger were landing following a cross-country flight. As soon as the nosewheel touched down on landing, the airplane pulled to the left. The pilot attempted to correct to the right and the airplane began swerving and exited the right side of the runway and came to a stop in a snow bank. The pilot told investigators the airplane had seven previous instances of the airplane pulling to the left during landing. In each of those cases, the steering departure occurred upon nosewheel touchdown and the pilot was able to regain control. Weather at the time of the accident was clear skies and the winds were variable at five knots. Postaccident examination of the airplane showed the nose gear rake angle was negative (-) .5 to -.7 degrees. Proper rake angle is 0.0 to positive .5 degrees. The manufacturers's analysis of the measured -.5 to -.7 degree rake angle showed that the rake angle maintained a positive margin of safety against dynamic nosewheel shimmy. The investigation could not determine the cause of the steering departure.

The National Transportation Safety Board determines the probable cause(s) of this incident to be:

The pilot's inability to maintain directional control of the airplane during landing for undetermined reasons.
