[Federal Register Volume 81, Number 91 (Wednesday, May 11, 2016)] [Proposed Rules] [Pages 29196-29198] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2016-10740] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-6427; Directorate Identifier 2015-NM-200-AD] RIN 2120-AA64 Airworthiness Directives; The Boeing Company AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). ----------------------------------------------------------------------- SUMMARY: We propose to supersede Airworthiness Directive (AD) 2007-11- 13, which applies to all The Boeing Company Model 717-200 airplanes. AD 2007-11-13 currently requires revising the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate new removal limits for certain components of the flap system and to reduce the inspection interval s for fatigue cracking of principal structural elements (PSE). Since we issued AD 2007-11-13, a new Airworthiness Limitations Instructions (ALI) revision was released that incorporates nondestructive inspection (NDI) techniques and reduced repetitive inspection intervals for three PSEs. We have determined that these reduced intervals are necessary to address the unsafe condition. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate reduced intervals for the inspections for three PSEs and add NDI techniques to the inspection process. We are proposing this AD to detect and correct fatigue cracking of certain PSEs. Such cracking could adversely affect the structural integrity of the airplane. DATES: We must receive comments on this proposed AD by June 27, 2016.

Discussion On June 29, 2007, we issued AD 2007-11-13, Amendment 39-15070 (72 FR 29237, May 25, 2007) (``AD 2007-11-13''), for all The Boeing Company Model 717-200 airplanes. AD 2007-11-13 requires revising the ALS of the Instructions for Continued Airworthiness to incorporate new removal limits for certain components of the flap system and to reduce the inspection intervals for fatigue cracking of PSEs. AD 2007-11-13 resulted from a revised damage tolerance analysis. We issued AD 2007- 11-13 to detect and correct fatigue cracking of certain PSEs. Such cracking could adversely affect the structural integrity of the airplane. Actions Since AD 2007-11-13 Was Issued Since we issued AD 2007-11-13, a new ALI revision was released that incorporates NDI techniques and reduced repetitive inspection intervals for three PSEs. We have determined that these reduced intervals are necessary to address the unsafe condition. Related Service Information Under 1 CFR Part 51 We reviewed Boeing 717-200, Report MDC-96K9063, Airworthiness [[Page 29197]] Limitations Instructions, Revision 14, dated July 2015. The service information describes procedures for inspecting PSEs, and includes a change to reduce the interval inspections for three PSEs and adds NDI techniques to the inspection process. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. FAA's Determination We are proposing this AD 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. Proposed AD Requirements This proposed AD would retain all requirements of AD 2007-11-13. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate reduced intervals for the inspections for three PSEs and add NDI techniques to the inspection process. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (k) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane. Costs of Compliance We estimate that this proposed AD affects 572 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost product operators ---------------------------------------------------------------------------------------------------------------- Maintenance or inspection program revision. 1 work-hour x $85 per hour = $85... $85 $48,620 ---------------------------------------------------------------------------------------------------------------- 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 have 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 that the 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 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD) 2007-11-13, Amendment 39-15070 (72 FR 29237, May 25, 2007), and adding the following new AD: The Boeing Company: Docket No. FAA- 2016-6427; Directorate Identifier 2015-NM-200-AD.
