AD 2011-26-04required inspection, replacement if necessary, and proper clamping of externally mountedfuel injector fuel lines. This new AD retains the requirements of AD 2011-26-04, andexpands the list of affected engine models. This AD was prompted by revised serviceinformation that added engine models to the applicability. We are issuing this AD toprevent failure of the fuel injector fuel lines, which could lead to uncontrolled engine fire,engine damage, and damage to the airplane.DATES: This AD is effective [INSERT DATE 35 DAYS AFTER DATE OFPUBLICATION IN THE FEDERAL REGISTER].The Director of the Federal Register approved the incorporation by reference ofcertain publications listed in this AD as of [INSERT DATE 35 DAYS AFTER DATE OFPUBLICATION IN THE FEDERAL REGISTER].

AD 2011-26-04 applied to certain fuel injected reciprocating2

engines manufactured by Lycoming Engines. The NPRM published in the FederalRegister on November 25, 2013 (78 FR 70240). The NPRM was prompted by revisedservice information that added engine models to the applicability. The NPRM proposedto expand the scope by adding the IO-540-C1C5 and IO-540-D4B5 engine models andrequiring inspection, replacement if necessary, and proper clamping of externallymounted fuel injector fuel lines. We are issuing this AD to prevent failure of the fuelinjector fuel lines, which could lead to uncontrolled engine fire, engine damage, anddamage to the airplane.Related Service Information under 1 CFR part 51We reviewed Lycoming Engines Mandatory Service Bulletin (MSB) No. 342G,dated July 16, 2013; Supplement No. 1 to MSB No. 342G, dated August 29, 2013; andSupplement No. 2 to MSB No. 342G, dated January 23, 2014. The servi e reviewed the relevant data, considered the comments received, anddetermined that air safety and the public interest require adopting this AD with thechanges described previously. We have determined that these changes: re consistent with the intent that was proposed in the NPRM forcorrecting the unsafe condition; and Do not add any additional burden upon the public than was alreadyproposed in the NPRM.We also determined that these changes will not increase the economic burden onany operator or increase the scope of this AD.Costs of ComplianceWe estimate that this AD will affect about 37,270 engines installed on airplanesof U.S. registry. We also estimate that it will require 1 hour to inspect 19,081 fourcylinder engines, 1.5 hours to inspect 18,000 six cylinder engines, and 2 hours to inspect189 eight cylinder engines. The average labor rate is 85 per hour. Based on thesefigures, we estimate the cost of this AD on U.S. operators to be 3,949,015.Authority for this RulemakingTitle 49 of the United States Code specifies the FAA’s authority to issue rules onaviation 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’sauthority.We are issuing this rulemaking under the authority described in Subtitle VII,Part A, Subpart III, Section 44701: “General requirements.” Under that section, Congresscharges the FAA with promoting safe flight of civil aircraft in air commerce byprescribing regulations for practices, methods, and procedures the Administrator findsnecessary for safety in air commerce. This regulation is within the scope of that authority6

because it addresses an unsafe condition that is likely to exist or develop on productsidentified in this rulemaking action.Regulatory FindingsThis AD will not have federalism implications under Executive Order 13132. ThisAD will not have a substantial direct effect on the States, on the relationship between thenational government and the States, or on the distribution of power and responsibilitiesamong 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 to the extent that it justifiesmaking a regulatory distinction, and(4) Will not have a significant economic impact, positive or negative, on asubstantial number of small entities under the criteria of the Regulatory Flexibility Act.List of Subjects in 14 CFR Part 39Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.Adoption of the AmendmentAccordingly, under the authority delegated to me by the Administrator, the FAAamends 14 CFR part 39 as follows:PART 39 - AIRWORTHINESS DIRECTIVES1.

Lycoming Engines requested that Lycoming SB 342G, Supplement No. 2, dated January 23, 2014 be added to this AD. Lycoming said that SB 342G, Supplement No. 2 removes the eight inch spacing dimension between clamps and corrects Diagram No. 30 for the IO-540-M1C5 engine model. We agree. We changed this AD t
