Deferred Maintenance on the Air Force C-130 Aircraft
Abstract
We determined the extent and causes of deferred maintenance on the U.S. Air Force C-130 aircraft used in support of operations in Southwest Asia. Specifically, we assessed the Air Force Materiel Command (AFMC) procedures for reporting deferred maintenance on the C-130 aircraft. We focused on maintenance deferred from October 1, 2004, through August 1, 2008. AFMC did not have an adequate internal control process for managing deferred C-130 aircraft Programmed Depot Maintenance (PDM). Specifically, AFMC did not ensure that: PDM was performed by the scheduled date, C-130 aircraft obtained and retained the required PDM extensions, and a reliable process was in place for reviewing PDM extensions. In addition, partially deferred maintenance was not accurately recorded and reported. AFMC process for deferring PDM was inadequate because AFMC either did not have procedures or did not follow established procedures to comply with Federal and DOD regulations and Air Force instructions, including Air Force Technical Orders 00-25-107 and 00-25-4. As a result, the Air Force may have flown 36 C-130 aircraft that were considered unsafe and 11 of these may have flown over the course of 365 days or more.
