In an effort to ensure continued airworthiness and flight safety of aging C-130B/E aircraft fleet of the Turkish Air Force (TurAF), 2nd Air Supply and Maintenance Center (ASMC) Command has initiated and implemented an analytical control program to solve structural problems before there are any catastrophic structural failures. As the aircraft grow older, the potential for fatigue cracking and corrosion increases. Many of the aging aircraft in the TurAF inventory are experiencing increased maintenance costs because one or more of these problems are present. To varying degrees, all of these older aircraft have encountered, or can be expected to encounter, aging problems such as fatigue cracking, stress corrosion cracking, corrosion, and wear. The critical fatigue component for the C-130 fleet is the center wing box, which is structurally more susceptible to the stresses of mission profile and payload. For center wings with 30,000 or greater equivalent flight hours (EFH), an inspection program to detect generalized cracking and possible onset of Widespread Fatigue Damage (WFD) should be instituted in accordance with 2nd ASMC Time Change Technical Order (TCTO) based on Service Bulletin 82-790, which includes center wing general cracks and common fatigue damage inspections.
