US Airways issued the following statement in response to the proposed civil penalty by the Federal Aviation Administration (FAA):

"Safety is at the forefront of everything we do at US Airways. Today's proposed penalty dates back to challenges we experienced during the integration of maintenance systems and processes on flights that occurred in 2008 and January 2009. Our team worked cooperatively with the FAA to investigate and correct any discrepancies to the FAA's satisfaction.

"Over the past nine months, we and the FAA have completed a formal review of our aircraft maintenance tracking systems as well as a comprehensive review of our maintenance program. This collaborative process included efforts to identify the issues, drill down to find the root cause and develop comprehensive fixes.

"We appreciate the FAA's guidance and oversight throughout this process. The changes we have made have improved upon an already solid maintenance program. With these challenges behind us, we look forward to continuing our relationship with the FAA to deliver on our common mission of safety first.

"US Airways will continue to work with the FAA in a cooperative manner to promptly achieve a negotiated resolution of the FAA's civil penalty proposal."
