The crew of an Air Canada Airbus A320-200, registration C-FDSU performing flight AC-921 from West Palm Beach,FL (USA) to Toronto Pearson,ON (Canada) with 135 passengers, experienced a loud popping sound associated with an unexpected yaw while climbing towards 10.000 feet during departure from West Palm Beach. Reporting mechanical trouble the crew decided to return to West Palm Beach to have the airplane inspected, but did not declare emergency or request the presence of emergency services. In coordination with Air Canada’s dispatch it was decided in the end to divert the airplane to Fort Lauderdale,FL, where the airplane landed safely about one hour after takeoff.
Air Canada dispatched a replacement aircraft to Fort Lauderdale.
The FAA and Air Canada said, that the airplane may have hit a bird during departure.
