Ernie Dinglas, a technical writer for Boeing, watches as U.S. Air Force Tech. Sgt. Michael Thompson, 167th Maintenance Group, replaces an antennae on top on a C-17 Globemaster III aircraft, as part of a Time Compliance Technical Order verification process at Shepherd Field, Martinsburg, West Virginia, July 12, 2023 . The TCTO team comprised of Boeing representatives and retrofit managers from the Air Force Lifecycle Management Center’s C-17 Program Office verified three TCTO’s with assistance from 167th Airlift Wing aircraft maintainers, July 10-14, 2023. The C-17 TCTO’s are directives, written by Boeing engineers, issued to provide instructions to aircraft maintainers for accomplishing one-time changes, modifications or inspections of equipment. The TCTO team works with maintainers to ensure the TCTO is correct before it is released to the field for implementation. (U.S. Air National Guard photo by Senior Master Sgt. Emily Beightol-Deyerle)
