Incident at SASKATOON / JOHN G. DIEFENBAKER INTL SK (CYXE)

Summary

2003-09-03: C-FKIS, a Piper PA-22 Tri-Pacer, was inbound to Saskatoon when the pilot advised Tower that he was experiencing a rough running engine due to the carb heat being stuck ""on"". The pilot requested and received a high and close in approach to ensure adequate altitude in the event of a failure. AFF was sent to standby positions. The a/c landed on Runway 33 without further incident and no other aircraft were inconvenienced.
2003-09-04: UPDATE TSB reported that the Piper PA-22-150, C-FKIS, was operating at 4,500 feet ASL in the Saskatoon training area when the crew observed a decrease in engine RPM of about 300-400 RPM and the engine began to run rough. The student pilot pulled the carb heat on, but this had no effect. He then leaned the mixture and the engine operation improved. The crew maintained 4,500 feet on their return to Saskatoon and landed without further incident. Maintenance examination determined the carburetor heat flapper valve shaft had broken, allowing the flapper valve to move freely.
