Aircraft; Human Factors; Weather
The incident occurred during the roll-out shortly after landing. Prior to the roll-out; the aircraft bounced lightly once on landing; the bounce was corrected with some power and another flare and landed without another bounce. During the roll-out the aircraft maintained runway center-line briefly and then began a slight right turn. Left rudder pedal pressure was applied in an attempt to correct the turn. The aircraft continued to turn right; with the rate of turn increasing rapidly. In response; more left rudder pedal pressure was applied and left brake was momentarily activated but quickly released. Aircraft continued the right turn off the runway; control could not be regained.The cause of the incident may have been due to shifting winds that were not observed during the roll-out. Winds on the field were light but were enough to cause an issue with the aircraft during roll-out. The aircraft listed is a C150 with a tail-wheel conversion.Typically; no brake pressure is applied during the roll-out until after a significant decrease in speed is observed; hence no brake pressure being applied sooner during the roll-out. This is to prevent flipping the aircraft onto its back and/or to prevent pilot induced oscillations leading to a ground loop and/or subsequent loss of control.In retrospect; when the aircraft began its turn to the right; the left rudder pedal pressure applied was the correct measure. However; with the turn rate increasing; left brake pressure should have been applied sooner to arrest the turn.
Reporter stated wind shift more then likely was the cause; possible tail wheel was not aligned correctly; propeller damaged.
