Accident Overview

On December 15, 2014, at approximately 1030 central standard time, a Piper PA-46-350P airplane, registration N224JJ, departed the left side of runway at Sugar Land Regional Airport (SGR), Houston, Texas. The commercial rated pilot was not injured. The aircraft was registered to and operated by Dilkara Leasing LLC, Las Vegas, Nevada, under 14 CFR Part 91 as a personal flight. Visual meteorological conditions prevailed, and an instrument flight plan was filed. The flight had departed Georgetown Municipal Airport (KGTU), Georgetown, Texas, about 0940.

Pilot Report

The pilot reported crossing the runway threshold at 100 feet and 85 knots, touching down at approximately 80-85 knots. When the nosewheel contacted the runway, the airplane veered sharply left. Despite application of right rudder, the airplane continued off the left side of the runway. The nose gear collapsed, and the airplane came to rest about 150 feet from the runway. After the accident, an operations supervisor from the Fixed Based Operator (FBO) inspected the marks on the runway; at the point where the nosewheel first contacted, it appeared the wheel had turned 90 degrees to the left.
