Incident at EDMONTON INTL AB (CYEG)

Summary

2003-03-06: UPDATE TSB reported that Air Canada ACA 106, an Airbus A319 was climbing through 9,000 feet when the crew heard a loud bang. The flight returned to Edmonton for inspection, with emergency vehicles standing by. Maintenance found one fan blade on the number one engine (CFM International CFM56-5A5) damaged and a 6 inch by 8 inch block of ice stuck to the engine intake. The aircraft had sat for about 60 minutes at the end of the runway in light snow and blowing snow conditions, after de-icing and before takeoff. Maintenance suspects that snow built up in the intake during the ground wait time, turned to ice and then came off after take-off because of the higher TAI (Thermal Anti-Ice) temperatures. The damaged fan blade will be replaced.
2003-03-05: ACA 106, an A319, departed from Runway 30 at Edmonton for Toronto and as the a/c passed through 9,000 feet, the crew advised that they thought the a/c had hit something. They elected to return and landed safely at 1638Z. Initial inspection of the engines confirmed fan blade damage in one engine. Company maintenance is currently assessing the engine, which appears to have damage to only one fan blade. It is unknown at this time if the engine ingested an object. TSB is waiting for a report from the company.
