RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period.
 SUMMARY: We are revising an earlier proposed airworthiness directive (AD) that proposed to supersede AD 95-26-11, for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011 series airplanes. AD 95-26-11 currently requires repetitive inspections to detect cracking of the fittings that attach the aft pressure bulkhead to the fuselage stringers, repetitive inspections to detect cracking of the fittings and of the splice tab of the aft pressure bulkhead, and corrective actions if necessary. The NPRM proposed to reduce the compliance time; add inspections for cracking of certain aft fuselage skin panels; add a structural modification; and also add a post-modification inspection program. The NPRM was prompted by a determination that the fittings at stringer attachments to the upper region of the aft pressure bulkhead are subject to widespread fatigue damage (WFD), which could result in cracking in the aft pressure bulkhead. This action revises the NPRM by reducing the post-structural modification repetitive inspection interval. We are proposing this supplemental NPRM (SNPRM) to prevent simultaneous failure of multiple stringer end fittings through fatigue cracking at the aft pressure bulkhead, which could lead to rapid decompression of the airplane. Since this action imposes an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
 DATES: We must receive comments on this SNPRM by January 2, 2015.

Discussion We issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011 series airplanes. The NPRM published in the 
                    **Federal Register**
                     on April 14, 2014 (79 FR 20819). The NPRM proposed to supersede Airworthiness Directive AD 95-26-11, Amendment 39-9469 (60 FR 66870, December 27, 1995), for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011 series airplanes. AD 95-26-11 currently requires repetitive inspections to detect cracking of the fittings that attach the aft pressure bulkhead to the fuselage stringers, repetitive inspections to detect cracking of the fittings and of the splice tab of the aft pressure bulkhead, and corrective actions if necessary. The NPRM proposed to reduce the compliance time; add inspections for cracking of certain aft fuselage skin panels; add a structural modification; and also add a post-modification inspection program. Actions Since Previous NPRM Was Issued Since we issued the NPRM, we have determined that the post-structural modification repetitive inspection interval should be revised. Comments We gave the public the opportunity to comment on the NPRM (79 FR 20819, April 14, 2014). The following presents the comment received on the NPRM, and the FAA's response to the comment. Request To Revise Repetitive Inspection Compliance Time Lockheed requested that we revise the post-structural modification repetitive inspection interval in paragraph (s) of the NPRM (79 FR 20819, April 14, 2014) from 13,875 flight cycles to 1,750 flight cycles. Paragraph (s) of the NPRM is identified as paragraph (r) in this SNPRM. Lockheed explained that the 1,750 flight cycles inspection interval meets the intent of Lockheed Service Bulletin 093-53-105, Revision 3, dated May 31, 2013. We agree to revise the repetitive inspection interval in paragraph (r) of this SNPRM to 1,750 flight cycles. The 13,875 flight cycles interval was a typographical error. Revised Compliance Time We have also determined that if any cracking is found during any inspection specified in this SNPRM, it must be repaired before further flight in order to address the identified unsafe condition. We have removed (q) of this SNPRM, which deferred replacement of cracked fittings/splice tabs and certain inspections. We have revised the compliance time inparagraph (m)(1)(ii) of this AD from “within 1,750 flight cycles after finding the crack” to “before further flight.” In addition, we added “The deferral specified in paragraphs (m)(1) and (m)(2) of this AD cannot be done as of the effective date of this AD.” We have also revised paragraphs (n) and (o) of this SNPRM to remove the reference to paragraph (q) of this SNPRM. FAA's Determination We are proposing this SNPRM because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. The change described above expands the scope of the NPRM (79 FR 20819, April 14, 2014). As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Proposed Requirements of This SNPRM This SNPRM would retain certain requirements of AD 95-26-11, Amendment 39-9469 (60 FR 66870, December 27, 1995). This SNPRM would reduce the compliance time; add inspections for cracking of certain aft fuselage skin panels; add a structural modification; and also add a post-modification inspection program. Costs of Compliance We estimate that this proposed AD affects 26 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs

 We have received no definitive data that would enable us to provide cost estimates for the other 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 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.
