Mountain Air Cargo is the subject of a proposed FAA penalty of $132,425 for allegedly incorrectly repairing one of the company’s ATR 42s. The agency accused the Maiden, N.C.-based operator of failing to accurately follow the FAA-approved aircraft maintenance manual when it repaired a rear cargo door and then operated that same aircraft on 115 flights between Aug. 7 and Oct. 29, 2012. Mountain Air Cargo is scheduled to meet with the FAA later this month to discuss the issue.
