[Federal Register Volume 83, Number 181 (Tuesday, September 18, 2018)] [Rules and Regulations] [Pages 47044-47047] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2018-19853] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2018-0327; Product Identifier 2018-CE-001-AD; Amendment 39-19404; AD 2018-19-04] RIN 2120-AA64 Airworthiness Directives; Learjet, Inc. Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain Learjet, Inc. Models 28, 29, 31, 31A, 35, 35A, 36, 36A, 55, 55B, 55C, and 60 airplanes. This AD was prompted by fatigue cracks initiating in the flap support structure due to repetitive flap loads, which has caused flap nose roller support bracket failure. This AD requires replacement of the flap nose roller fitting, nose roller support bracket, and adjacent rib support structure with improved components. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 23, 2018. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 23, 2018. ADDRESSES: For service information identified in this final rule, contact Learjet, Inc., One Learjet Way, Wichita, Kansas 67209; telephone: 316-946-2000; email: ac.ict@aero.bombardier.com; internet: https://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. Models 28, 29, 31, 31A, 35, 35A, 36, 36A, 55, 55B, 55C, and 60 airplanes. The NPRM published in the Federal Register on May 8, 2018 (83 FR 20740). The NPRM was prompted by a report that a skewed flap and aileron became bound on a Model 31A airplane, which was later found to have fatigue cracks in the flap support structure due to repetitive flap loads. Fatigue cracks in the flap support structure caused by repetitive flap loads can result in failure of the flap nose roller support bracket. Repetitive flap loads occur on all models identified by this AD. The NPRM proposed to require replacement of the flap nose roller fitting, nose roller support bracket, and adjacent rib support structure with improved components. This condition, if not addressed, could result in loss of roll control on approach with consequent loss of control of the airplane. We are issuing this AD to address the unsafe condition on these products. Comments We gave the public the opportunity to participate in developing this final rule. We received no comments on the NPRM or on the determination of the cost to the public. Clarification of Repair Method We have revised this action to clarify that operators are not required to obtain repair instructions from Learjet. Instead, operators must use a repair method approved by the Manager, Wichita ACO Branch, FAA. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed except for the changes described previously and other minor editorial changes. We have determined that these changes:Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Learjet 28/29 Service Bulletin SB 28/29-27- 31 Recommended, dated September 11, 2017; Bombardier Learjet 31 SB 31- 27-35 Recommended, dated September 11, 2017; Bombardier Learjet 35/36 SB 35/36-27-50 Recommended, dated September 11, 2017; Bombardier Learjet 55 SB 55-27-41 Recommended, dated September 11, 2017; and Bombardier Learjet 60 SB 60-27-39 Recommended, Revision 1, dated January 15, 2018. For the applicable models, the service information describes procedures for replacement of the flap nose roller fitting, nose roller support bracket, and adjacent rib support structure with improved components. The service information also contains instructions to ensure correct flap alignment. 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. Costs of Compliance We estimate that this AD affects 706 airplanes of U.S. registry. We estimate the following costs to comply with this AD: Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost per Cost on U.S. Action Labor cost Parts cost * product operators ---------------------------------------------------------------------------------------------------------------- Replacement of flap nose roller 188 work-hours x $85 per $12,213 $28,193 $19,904,258 fitting, nose roller support bracket, hour = $15,980. and adjacent rib support structure with improved components. ---------------------------------------------------------------------------------------------------------------- * Parts cost is an average of the combined costs for replacement of all of the kits per airplane. Not all airplanes will need all kits, as credit is allowed for some previous installations. Individual Parts Cost * ------------------------------------------------------------------------ Kit Number (K/N) Part cost ------------------------------------------------------------------------ K/N 2381000-802.............................................. $827 K/N 2381000-804.............................................. 822 K/N 2381000-806.............................................. 780 K/N 2381000-808.............................................. 793 K/N 2381000-809.............................................. 1,358 K/N 2381000-810.............................................. 1,358 K/N 2381000-811.............................................. 1,822 K/N 2381000-817.............................................. 1,674 K/N 2381000-818.............................................. 1,432 K/N 2381000-819.............................................. 1,415 K/N 2381000-820.............................................. 1,912 K/N 2381000-821.............................................. 1,912 ------------------------------------------------------------------------ * Parts required for replacement may vary for different models and different airplanes. 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to small airplanes, gliders, balloons, airships, domestic business jet transport airplanes, and associated [[Page 47046]] appliances to the Director of the Policy and Innovation Division. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1.
