# SERVICE BULLETIN WINGS - REPLACEMENT OF OUTER WINGS 1. PLANNING INFORMATION A. EFFECTIVITY This Service Bulletin is applicable to all model382, 382B, 382E, 382F, and 382G series FAA Certificated Hercules aircraft (excluding 382J series aircraft) . B. REASON (1) The 14 CFR Part 26, Subpart CAging Aircraft Safety- Widespread Fatigue Damage rule became effective on January 14, 2011. In compliance with this rule, Lockheed Martin Aeronautics Company established a Limit ofValidity (LOV) for 382 series aircraft that is published in Section VII of customer specific Service Manual Publication (SMP) 515-C Inspection Programs. 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 Bulletin presents a maintenance action required for the outer 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 simultaneously at similar structural details and stress levels. Fatigue damage is increasingly likely as the aircraft is operated and aged, and without intervention, WFD is likely to compromise the structural integrity ofthe aircraft. Structural fatigue characteristics of airplanes are understood only up to the point where analyses and testing of the structure are valid. The purpose ofthis action is to replace the outerwings currently installed on the affected aircraft with an outer wing of new manufacture prior to the on-set ofWFD in the outer wing structure. (3) It is recommended that the following compliance timeline be followed for aircraft with outer wing serial numbers 3946 through 4541 or MEP 14Ytype replacement outerwings (Part No. 388021-9/-1 0) installed (indicated on the outer wing identification placard located on the rear beam web near OWS 180): (a) For aircraft with less than 30,000 flight hours on the outerwing, the outer wing shall be replaced priorto the accumulation of30,000 flight hours. (b) For aircraft with greater than 30,000 flight hours on the outer wing, the aircraft shall be grounded until the outerwing is replaced . (4) In accordance with 14 CFR § 26.21 , the Limit ofValidity (LOV) for all 382 Series aircraft is 58,000 Flight Cycles or 75,000 Flight Hours whichever comes first. The outer wing is subject to the 75,000 flight hour life limit ofthe LOV. Although Lockheed Martin does not consider the outer wing to be a rotable component, it is understood that 382 Series outer wings are interchangeable (with minimal systems modifications) between aircraft. EXPORT CONTROLLED INFORMATION WARNING -This document contains data whose export is restricted bythe Arms Export Control Act (Title 22, U.S.C., Sec 2751, et seq.) as amended, orthe ExportAdministration Act (Title 50, U.S.C., App 2401 etseq.) as amended.

# SERVICE BULLETIN Therefore, it is recommended that the following compliance timeline be followed for aircraft with outer wing serial numbers 4542 and up or all MEP replacement outerwings except the 14Y (Part No. 388021-9/-10) installed (indicated on the outer wing identification placard located on the rear beam web near OWS180): (a) For aircraft with less than 75,000 flight hours on the outer wing, the outer wing shall be replaced with an outer wing that has less than 75,000 flight hours prior to the accumulation of 75,000 flight hours on the subject outer wing. (b) For aircraft with greater than 75,000 flight hours on the outer wing, the aircraft shall be grounded until the outer wing is replaced with an outerwing that has less than 75,000 flight hours. All flight hour tracking and interchangeability concerns are the responsibility ofthe operator. Instructions described in Paragraph 2., Accomplishment Instructions, are not applicable to Outer Wing Serial Numbers 4542 and up, or MEP replacement outerwings except MEP 14Y (P/N 388021-9/-10.) Contact Lockheed Martin for replacement instructions. The replacement times indicated in this service bulletin do not apply to military operators of 382 , 3828, 382E , 382F, and 382G aircraft. Contact Lockheed Martin for an Operational Usage Evaluation/Service Life Assessment to determine an appropriate replacement schedule. For commercial operators of aircraft with outer wings that have had previous military usage, contact Lockheed Martin for adjusted compliance times. Lockheed Martin recommends replacement ofthe outerwing with one of new construction. Contact Lockheed Martin Aeronautics Company for part availability. Contact information can be found in Paragraph 1 .F. Installation and check-out of plumbing, fuel, electrical, hydraulic, flight control components, and system components are the responsibility ofthe owner/operator. Limited salvage information can be found in the applicable customer Maintenance Manual or Illustrated Parts Catalog. These work instructions refer to methods, techniques, and practices described in other Lockheed Martin Aeronautics Company documents. When the words "refer to" are used and the operator has other acceptable methods, techniques, and practices (including tools, equipment, and test equipment) those procedures may be used to complete the work. When the words "in accordance with" are included in the instruction , the methods, techniques, and practices (including tools, equipment, and test equipment) specified in the Lockheed Martin Aeronautics Company document must be used . C. DESCRIPTION This Service Bulletin provides instructions for replacing the outer wing structure on affected aircraft.
