Kalitta's staff, in collaboration with ATEC Engineering of Houston, also has designed and brought on stream a new 10-meter (33-ft.), 100,000-lb.-thrust-capable engine test cell. It accommodates powerplants that the MRO overhauls and repairs, which include the Pratt & Whitney JT9 and JT8 families (except the JT8-200); and the GE CF6-50 and -80.
The MRO is certified for line base, top case and tear-down for the CFM56-3 and -7, with complete overhaul certification on those engines “to be announced soon,” according to Couvreur. Other engine work focuses on auxiliary power units (APU), specifically the Garrett GTCP-85 and GTCP-660-4, and Pratt & Whitney-Canada PWC 901A.
“CFM56 overhauls require high-speed grinding, which can accomplish in seven hours what low-speed grinding systems need 40 to do,” and this is leading the MRO to install the machinery by August, says Couvreur.
One of the major infrastructure enhancements at Oscoda took place last October, when Kalitta Air purchased the equipment—specific to the overhaul, repair and testing of the CFM56-3 and -7B, and GE CF6-80C and -E—from LTQ Engineering, a now-closed Lufthansa Technik and Qantas Airways joint venture located in Tullamarine, Australia. Kalitta Maintenance installed that equipment at its facility in December.
