Takeoff and Incident
The pilot of a single-engine airplane had just received an IFR clearance. The airplane performed an intersection takeoff at night with winds gusting to 30 knots and blowing snow. Just prior to rotation, the pilot observed the airspeed indicator displaying '0'. He decided to continue the takeoff because he believed insufficient runway remained for an aborted takeoff.
Post-Takeoff Events
After takeoff, the pilot stated that his other pressure instruments were not functioning properly. The airplane collided with trees and terrain approximately 2 miles from the airport's center.
On-Scene Investigation
An on-scene investigation revealed a slight trace of ice on the wings' leading edge. One of the two static ports was found with ice blocking it. The second static port was destroyed during the crash sequence. The alternate static source switch was found in the 'standby' position.
Pilot Statement
The pilot stated, 'I figured I could use the alternate static source once I was up high enough to clear the trees.'
