### DEPARTMENT OF TRANSPORTATION

**Federal Aviation Administration**

**14 CFR Part 39**

**[Docket No. FAA–2011–0919; Directorate Identifier 2010–NM–088–AD]** 

**RIN 2120–AA64**



### Airworthiness Directives; Lockheed **Martin Corporation/Lockheed Martin Aeronautics Company Model L–1011**  **Series Airplanes**

**AGENCY** 

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

**ACTION** 

### : Notice of proposed rulemaking (NPRM).

**SUMMARY** 

### : We propose to adopt a new airworthiness directive (AD) for certain Model L–1011 series airplanes. This proposed AD would require repetitive inspections for cracking of the wing rear spar and upper surface zones, and repair if necessary. This proposed AD results from a damage tolerance analysis conducted by the manufacturer indicating that fatigue cracking could occur in those areas. We are proposing this AD to detect and correct such fatigue cracking, which could result in cracking that grows large enough to reduce the wing strength below certificated requirements and possibly cause fracture of the rear spar, resulting in extensive damage to the wing and possible fuel leaks.

**DATES** 

### : We must receive comments on this proposed AD by November 7, 2011.

Discussion

We previously issued AD 94–05–01, Amendment 39–8839 (59 FR 10275, March 4, 1994), and AD 2000–21–01, Amendment 39–11933 (65 FR 62994, October 20, 2000), which require modifications to extend the life of the wing rear spar inboard area. The modifications required by those two ADs removed cracks in the wing upper skin and installed repair bushings as necessary. The lower spar cap was modified by adding nested angles and cold working the attachment holes.

Based upon a damage tolerance analysis, additional inspections are required to ensure the structural integrity of the structure modified in accordance with those two ADs as well as the adjoining baseline structure. If cracking is undetected and unrepaired, it could result in cracking that grows large enough to reduce the wing strength below certificated requirements and possibly cause fracture of the rear spar, resulting in extensive damage to the wing and possible fuel leaks.

Relevant Service Information

We have reviewed Lockheed Service Bulletin 093–57–226, dated August 31, 2009. This service bulletin describes procedures for repetitive eddy current non-destructive inspections (NDI) and detailed inspections for cracking of the wing rear spar and upper surface zones. The service bulletin identifies inspections for the airplane models in the zones identified in the following table, titled ‘‘Inspections.’’


## 58417 Federal Register / Vol. 76, No. 183 / Wednesday, September 21, 2011 / Proposed Rules

### For airplanes on which cracking is found during any inspection, this service information specifies a bolt hole eddy current inspection to verify the cracking. The corrective actions for cracking include repairing cracking if the cracking is within specified limits, or contacting the manufacturer for repair instructions if the cracking is not within specified limits.
Related Rulemaking

AD 94–05–01, Amendment 39–8839 (59 FR 10275, March 4, 1994), and AD 2000–21–01, Amendment 39–11933 (65 FR 62994, October 20, 2000), specify structural modification installations on Model L–1011 series airplanes. This proposed AD would not change the requirements of AD 94–05–01 and AD 2000–21–01. However, this proposed AD would require new inspections for structures affected by the modifications required by those two ADs. FAA’s Determination and Requirements of this Proposed AD

We are proposing this AD because we evaluated all relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. This proposed AD would require accomplishing the actions specified in Lockheed Service Bulletin 093–57–226, dated August 31, 2009, described previously. Differences Between the Proposed AD and the Service Information

This proposed AD specifies initial compliance times and repetitive inspection intervals that differ from those contained in Lockheed Service Bulletin 093–57–226, dated August 31, 2009. The changes have been coordinated with Lockheed Martin and they concur with the FAA’s position. The compliance times were changes to simplify the inspection requirements. We also propose that all crack findings be repaired before further flight. We have determined that the compliance times, as proposed, represent the maximum interval of time allowable for the affected airplanes to continue to safely operate before the inspections and repairs, if necessary, are done.

Although that service bulletin specifies that operators may contact the manufacturer for disposition of certain repairs, this proposed AD would require operators to repair those conditions in accordance with a method approved by the FAA.

Interim Action

We consider this proposed AD interim action. If final action is later identified, we might consider further rulemaking then. Costs of Compliance

We estimate that this proposed AD affects 4 airplanes of U.S. registry.

We estimate the following costs to comply with this proposed AD:



### E STIMATED

### We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD.
Authority for This Rulemaking

Title 49 of the 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 of civil 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 determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on


## 58418 Federal Register / Vol. 76, No. 183 / Wednesday, September 21, 2011 / Proposed Rules

the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this proposed regulation:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866,

(2) Is not a ‘‘significant rule’’ under the 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 of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES** 

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**
