The US Federal Aviation Administration (FAA) has proposed a $275,000 fine against regional carrier Pinnacle Airlines for allegedly operating a Bombardier CRJ on 11 flights when the aircraft was not in compliance with federal regulations.
The FAA says the airline's mechanics had not followed instructions in the aircraft maintenance manual when they removed and replaced the aircraft's right engine. "Specifically, they did not install a required part," says the FAA.
The 11 flights were operated on 25, 26 and 27 October 2010.
Pinnacle filed for bankruptcy protection in April 2012. The FAA says its notice of the fine is not a demand for payment since the airline is under bankruptcy protection, adding that it filed the notice to prove its claim in the case.
