Verisurf Software and FARO Laser Tracker Reduce MRO Time

“The FARO Laser Tracker with Verisurf software ability to provide real-time measurements directly against the CAD data enables engineers to instantly visualize deviations from the nominal. The Tracker has dramatically reduced the time required to certify large parts, tooling and machinery while also resulting in substantial quality improvements.”

For almost 20 years, Marianna Airmotive Corporation (MAC) has been repairing and overhauling structural components for the Air Force’s largest aircraft, the C5 Galaxy. As typical for most repair facilities, Marianna does not have access to the aircraft itself so it must build and certify fixtures that it can use to assemble and fabricate structural components to tight tolerances. “The FARO Laser Tracker’s ability to provide realtime measurements directly against the CAD data enables engineers to instantly visualize deviations from the nominal,” said Bill Visage, an engineer associated with Marianna Airmotive. “It has dramatically reduced the time required to certify large parts, tooling and machinery while also resulting in substantial quality improvements.”

Aircraft Repair Challenges

Among the largest aircraft in the world, the Lockheed C-5 Galaxy is a military transport designed to carry outsized and oversized cargo over intercontinental distances. The first C-5 was delivered to the Air Force in 1968 and production ended when the 131st aircraft was delivered in 1989. The C5 features a cargo compartment that is 19 feet wide, 13.5 feet high, and 121 feet long, slightly longer than the length of the first powered flight by the Wright Brothers. The C5 is basically an aluminum skin and honeycomb core structure. Marianna’s contract includes repairing all significant C-5 structural components that are removable from the aircraft such as the main landing gear door, aft cargo door, spoilers, inlet cowls, slats, flaps, and radomes.
