Dallas Executive Airport-based AAT Aircraft Maintenance, an FAA-approved Part 145 repair station, has added several makes and models to its repair station certificate. To complement its existing approvals for the Gulfstream II/IIB/II-SP/III/IV and Hawker 700/800/800XP, it has added accreditation for the Falcon 50/50EX, Learjet 60 and King Air 200. The additional certification allows the MRO to perform light to heavy maintenance and major repairs and modifications. The MRO is also in the process of acquiring Mexican DGAC repair certification.
