14 CFR Part 39 [Docket No. FAA-201Q-1305; Directorate Identifier 2010-NM--{)74-AD ; Amendment 3!H6749; AD 2011-15--{)2] RIN 212Q-AA64 Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 3828, 382E, 382F, and 382G Airplanes AGENCY: 

### Federal Aviation Administration (FAA) , DOT

. ACTION: 

### Final rule.
SUMMARY: 

### We are superseding an existing airworthiness directive (AD) for all Model 382, 382B, 382E, 382F, and 382G airplanes

. That AD currently requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires the accomplishment of certain fuel system modifications, the initial inspections of certain repetitive fuel system limitations to phase in those inspections, and repair if necessary. This new AD corrects certain part number references, adds an additional inspection area, and for certain airplanes, requires certain actions to be re-accomplished according to revised service information. This AD was prompted by a report of incorrect accomplishment information in the service information cited by the existing AD. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: 

### This AD is effective August 19, 2011.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as ofAugust 19, 2011.

### neil.duggan @ faa.gov. SUPPLEMENTARY INFORMATION: Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede airworthiness directive (AD) 2008-20-01, amendment 39-15680 (73 FR 56464, September 29, 2008)

. That AD applies to the specified products. The NPRM published in the Federal Register on January 5 , 2011 (76 FR 485). That NPRM proposed to continue to require revising the maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements

. That NPRM also proposed to continue to require the accomplishment of certain fuel system modifications, the initial inspections of certain repetitive fuel system limitations to phase in those inspections , and repair if necessary. That NPRM also proposed

The current costs for AD 2008-20-01 are repeated for the convenience of aff

ected operators , as follows : 1 24 to correct certain part number ref erences, add an additional inspection area, and for certain airplanes , require certain actions to be re-accomplished according to revised service information. Comments

We gave the public the opportunity to participate in developing this AD

. The following presents the comment received on the proposal and the FAA 's response to the comment. Request To Revise Cost Estimate

Lynden Air Cargo requested that the cost for revising the Instructions for Continued Airworthiness be included in the Costs ofCompliance estimate

. Lynden Air Cargo stated that there is a significant amount of work-hours associated with revising " company manuals , job cards , maintenance programs , computerized tracking programs and record keeping documents " so that the operator can comply with the requirements ofa new AD

. Lynden Air Cargo estimated that these actions will take at least 80 workhours for its office staff, and estimated that this cost would affect other operators. Lynden Air Cargo also pointed out that this work load for the office staff will have a greater impact on ESTIMATED COSTS FOR NEW ACTIONS

We agree that a requirement ofthe new AD will require an update of the maintenance program to incorporate references to revised service information

. This action is estimated to take approximately 1 work-hour per airplane

. However, we disagree with increasing the estimated work-hours for the time that it takes for writing job cards, tracking programs, or recordkeeping, since those actions are not directly required by this AD. The costs specified by Lynden Air Cargo will not be the same for all operators. The Costs of Compliance estimate has been revised accordingly. Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting the AD as proposed. Costs ofCompliance

There are about 62 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs for U

.S

. operators to comply with this AD. The average labor rate per hour is $85. The costs of the new requirements of this AD are as follows:

### Authority for this Rulemaking

Title 49 ofthe United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs , describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, "General requirements." Under that section, Congress charges the FAA with promoting safe flight ofcivil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution ofpower and responsibilities among the various levels of government.

For the reasons discussed above, I certify that this AD:

(1) 

### Is not a "significant regulatory action" under Executive Order 12866,

(2) 

### Is not a "significant rule" under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),

(3) Will not affect intrastate aviation in Alaska, and

(4) 

### Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List ofSubjects in 14 CFR Part 39

AGENCY: 

### Federal Aviation Administration (FAA), DOT. ACTION : 

### Final rule.
SUMMARY: 

### We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires a detailed inspection to detect distress and existing repairs to the leading edge structure of the vertical stabilizer at the splice at Station Zfs = 

### 52.267; repetitive inspections for cracking in the front spar cap forward flanges of the vertical stabilizer, and either the aft flanges or side skins; repetitive inspections for loose and missing fasteners ; and related investigative and corrective actions if necessary
. This AD was prompted by reports of cracked vertical stabilizer skin, a severed front spar cap, elongated fastener holes at the leading edge of the vertical stabilizer, and a cracked front spar web and front spar cap bolt holes in the vertical stabilizer. We are issuing this AD to detect and correct such cracking damage, which could result in the structure being unable to support limit load, and could lead to the loss of the vertical stabilizer. DATES: 

### This AD is effective August 19, 2011.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as ofAugust 19, 2011
