Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Learjet Inc. Model 45 airplanes. This AD was prompted by reports of non-conforming windshield supports (coupe rails). This AD requires a general visual inspection of the coupe rails to detect gouging and scratches, and to determine if a radius has been removed; an ultrasound inspection to measure the dimensions of the lower coupe rails; an eddy current inspection to detect cracks of the lower coupe rails; replacement of [[Page 34259]] the lower coupe rails if necessary; and revision of the maintenance or inspection program, as applicable. We are issuing this AD to detect and correct non-conforming windshield supports, which could result in uncontrolled cabin depressurization and compromise of the capability of the windshield to withstand a bird strike. DATES: This AD is effective July 21, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of July 21, 2015. ADDRESSES: For service information identified in this AD, contact Learjet, Inc., One Learjet Way, Wichita, KS 67209-2942; telephone 316- 946-2000; fax 316-946-2220; email [email protected]; Internet http://www.bombardier.com.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Learjet Inc. Model 45 airplanes. The NPRM published in the Federal Register on April 16, 2014 (79 FR 21416). The NPRM was prompted by reports of non-conforming windshield supports (coupe rails). The NPRM proposed to require a general visual inspection to detect gouging and scratches and to determine if a radius has been removed; an ultrasound inspection to measure the dimensions of the lower coupe rails; an eddy current inspection to detect cracks of the lower coupe rails; replacement of the lower coupe rails if necessary; and revision of the maintenance or inspection program, as applicable. We are issuing this AD to detect and correct non-conforming windshield supports, which could result in uncontrolled cabin depressurization. Non-conforming windshield supports could also compromise the capability of the windshield to withstand a bird strike. Explanation of Changes Made to Paragraph (h) of This AD We revised paragraph (h) of this AD to state that incorporation of certain tasks into the maintenance or inspection program, as applicable, must be done in accordance with a method approved by the Manager, Wichita Aircraft Certification Office (ACO), ACE-115W, FAA. For informational purposes, we have added new Notes 1 and 2 to paragraph (h) of this AD to refer to the latest maintenance manuals as guidance material for revising the maintenance or inspection program. (Earlier revisions were referenced previously in table 1 to paragraph (h) of the NPRM (79 FR 21416, April 16, 2014)). The change to this AD should allow operators to obtain appropriate versions of maintenance manuals in order to facilitate compliance. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 21416, April 16, 2014), and the FAA's response to each comment. Request for Credit for Previous Actions Learjet Inc. requested that we revise the NPRM (79 FR 21416, April 16, 2014) to clarify whether actions accomplished using Bombardier Recommended Service Bulletin 40-56-03, dated April 30, 2012; or Bombardier Recommended Service Bulletin 45-56-3, dated April 30, 2012; is acceptable for compliance with the actions required by paragraph (g) of the NPRM. Learjet Inc. reasoned that many operators have already done those actions using this service information. We agree to clarify. Actions required by paragraph (g) of this AD, if performed before the effective date of this AD using Bombardier Recommended Service Bulletin 40-56-03, dated April 30, 2012; or Bombardier Recommended Service Bulletin 45-56-3, dated April 30, 2012; as applicable; are acceptable for compliance with the requirements of paragraph (g) of this AD. We have added a new paragraph (j) to this AD to provide credit for these actions. We have redesignated subsequent paragraphs accordingly. Request To Incorporate Updated Inspection Reference Number (IRN) Learjet Inc. requested that we revise table 1 to paragraph (h) of the NPRM (79 FR 21416, April 16, 2014) to allow the incorporation of IRN V5323168, as specified in Bombardier Learjet 45 Maintenance Manual (MM) MM-104, Revision 62; and Bombardier Learjet 40 Maintenance Manual MM-105 Revision 30; both dated June 2, 2014. Learjet Inc. explained that IRN U5323168 was revised to V5323168 in Bombardier Learjet 45 Maintenance Manual MM-104, Revision 62; and Bombardier Learjet 40 Maintenance Manual MM-105, Revision 30; both dated June 2, 2014. Learjet Inc. stated that there were no actual changes to the content of the IRN in Chapter 4 of the MMs, but the ``U'' was revised to a ``V'' to coincide with changes to the verbiage in the same IRN in Chapter 5 of those MMs. As discussed previously, we added new Notes 1 and 2 to paragraph (h) of this AD to refer to the latest revisions of the maintenance manuals, which include references to the appropriate IRNs referenced by the commenter. No additional change to this AD is necessary. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes:Are consistent with the intent that was proposed in the NPRM (79 FR 21416, April 16, 2014) for correcting the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 21416, April 16, 2014). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. [[Page 34260]] Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Recommended Service Bulletin 40-56-03, Revision 1, dated October 15, 2012; and Bombardier Recommended Service Bulletin 45-56-3, Revision 1, dated October 15, 2012. The service information describes procedures for a general visual inspection of the coupe rails to detect gouging and scratches, and to determine if a radius has been removed; an ultrasound inspection to measure the dimensions of the lower coupe rails; an eddy current inspection to detect cracks of the lower coupe rails; and replacement of the lower coupe rails if necessary. 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 of this AD. Costs of Compliance We estimate that this AD affects 351 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspection...................... 40 work-hours x $77............... $3,477 per $1,220,427 per $85 per hour = inspection cycle. inspection cycle. $3,400 per inspection cycle. Maintenance or inspection 1 work hour x $85 None.............. $85............... $29,835. program revision. per hour = $85. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary replacement that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need this replacement: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Action Labor cost Parts cost Cost per product ---------------------------------------------------------------------------------------------------------------- Replacement........................ 500 work-hours (to replace $15,000 (to replace $57,500 (to replace both coupe rails) x $85 both coupe rails). both coupe rails). per hour = $42,500. ---------------------------------------------------------------------------------------------------------------- According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 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 of power 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.
