American Airlines has attained a goal to complete CFM56-7 engine overhauls in 58 days at its largest maintenance base in Tulsa, Oklahoma.
Officials from the Tulsa base outlined the current turn time to ATI during a site visit on 26 April.
American performs airframe overhaul and component work for Boeing 737s, 757s and MD-80 aircraft at its Tulsa facility, which completed 549 heavy and light aircraft modifications in 2010. Technicians in Tulsa also completed 662 engine overhauls last year and 248 individual landing gear overhauls.
As the carrier reaches its turn time goal on CFM overhauls, American also aims to cut completion times for thrust reverser overhaul to 20 days from a current average of 30 days. American aims to reach the 20 day benchmark by June after averaging overhaul completion times for thrust reversers of 50 days in 2010.
American has a total of six hangars in Tulsa, and just finished a line of 777 overhauls at the site. That line, housed in hangar six, will now be used for a 757 mid-check line, states Troy Sokolowski, maintenance manager for hangars five and six in Tulsa.
