# SERVICE BULLETIN WINGS - REPLACEMENT OF CENTER WING 1
. PLANNING INFORMATION A. EFFECTIVITY This Service Bulletin is applicable to all model 382 , 382B , 382E , 382 F , and 382G series FAA Certificated Hercules aircraft (excluding 382J series aircraft)
. B
. REASON (1) The 14 C F R Part 26 , Subpart CAging Aircraft Safety- Widespread Fatigue Damage ru le be ca me effective on January 14 , 2011
. In compliance with this ru le , Lockheed Martin Aeronautics Company established a Limit of Validity ( LOV) for 382 series aircraft , published in Section VII of customer specific Service Manual Publication (SMP) 515-C Inspection Prog ra ms . 14 CFR Part 121 or Part 129 operators must have incorporated the LOV into their maintenance program by July 14 , 2013 to comply with FAR §121
. 1115 or §129.115

. This Service Bulleti n presents a maintenance action required for the center wing to safeguard the aircraft against widespread fatigue damage up to the LOV
. (2) Widespread Fatigue Damage (WFD) is general degradation of large areas of structure with fatigue cracks manifesting and growing sim ultaneous ly at sim ilar structural details and stress levels
. Fatigue damage is increasingly likely as the airplane is operated and aged , and without intervent ion , WFD is likely to comp romise the structural i ntegri ty of the airplane
. Structural fatigue characteristics of airplanes are understood only up to the point where ana lyses and testing of the structure are valid
. The purpose of this action is to replace the center w i ng box currently installed on th e affected ai rcraft with a wing box of new manufacture prior to the on - set of WFD i n the center wing box structure
. (3) For those aircraft with less than 50 ,000 Center Wing Flight H ours , Lockheed Martin Aeronautics Company recommends replacement of the center wing prior to the accumulation of 50 ,000 Center Wing Flight Hours. (4) For those aircraft w ith more than 50 ,000 Center Wing Flight Hours , the ai rcraft shou ld be grounded until the repla cement of the center wing is accomplished

. (5) Aircraft that have in corporated Service Bulletin SB 382-57-90 conform to the i ntent of this Servi ce Bulletin and do not need to accomplish the modifications specified herein
. The repla ce ment times indicated in this Service Bulleti n do not apply to military operators of 382 , 382B , 382E , 382 F , and 382G aircraft
. Contact Lockheed Martin for an Operationa l Usage Evaluation/Service Life Assessment to determine an appropriate replacement schedule
. Lead time for the purchase of a center wing box of new construction is approximately 24 months
. Lockheed Martin Aeronautics Company contact information ca n be found in Paragraph 1
. F
