[Federal Register Volume 82, Number 61 (Friday, March 31, 2017)] [Rules and Regulations] [Pages 15982-15985] From the Federal Register Online [www.thefederalregister.org] [FR Doc No: 2017-05857] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA-2016-9531; Directorate Identifier 2015-CE-011-AD; Amendment 39-18839; AD 2017-07-01] RIN 2120-AA64 Airworthiness Directives; M7 Aerospace LLC Models Airplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: We are adopting a new airworthiness directive (AD) for certain M7 Aerospace LLC Models SA226-T, SA226-AT, SA226-T(B), SA226-TC, SA227- AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), and SA227-TT airplanes. This AD was prompted by detachment of the power lever linkage to the TPE331 engine propeller pitch control. This AD requires repetitively inspecting the propeller pitch control for proper torque, with corrections as necessary until required replacement or rework of the PPC assembly to have a threaded hole in the splined end of the shouldered shaft and installation of a secondary retention device is done. We are issuing this AD to correct the unsafe condition on these products. DATES: This AD is effective May 5, 2017. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of May 5, 2017.

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 M7 Aerospace LLC Models SA226-T, SA226-AT, SA226-T(B), SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), and SA227-TT airplanes. The NPRM published in the Federal Register on December 28, 2016 (81 FR 95528). The NPRM was prompted by reports of the airplane power lever linkage detaching from the TPE331 engine propeller pitch control (PPC) shaft. In flight operations, detachment may result in fuel flow to the engine remaining constant regardless of the power lever movement by the pilot. The orientation of the engine on certain M7 Aerospace airplanes increases the vulnerability of detachment. The PPC lever is an airplane part and its detachment from [[Page 15983]] the TPE311 has been the subject of previous ADs on other airplane type designs. The NPRM proposed to require repetitive inspections of the PPC lever with corrective action as necessary until required replacement or rework of the PPC assembly to have a threaded hole in the splined end of the shouldered shaft and installation of a secondary retention feature for the airplane control linkage interface is done. We are issuing this AD to correct the unsafe condition on these products. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed. We have determined that these minor changes: Are consistent with the intent that was proposed in the NPRM for correcting 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 M7 Aerospace LLC SA226 Series Service Bulletin 226-76- 012, dated March 17, 2015; M7 Aerospace LLC SA227 Series Service Bulletin 227-76-007, dated March 17, 2015; and M7 Aerospace LLC SA227 Series Commuter Category Service Bulletin CC7-76-004, dated March 17, 2015; that, in combination with the temporary revisions and service bulletin listed below, describes the actions that must be done for the applicable models to comply with this AD. We also reviewed M7 Aerospace SA226 Series Maintenance Manual Temporary Revision 71-02, dated March 15, 2016; M7 Aerospace SA227 Series Maintenance Manual Temporary Revision 71-03, dated March 15, 2016; and M7 Aerospace SA227 Series Commuter Category Maintenance Manual Temporary Revision 71-02, dated March 15, 2016; that describes procedures for installing the secondary retention device on the PPC assembly and doing a visual inspection of the PPC lever for the applicable models. We also reviewed Honeywell International Inc. Service Bulletin TPE331-72-2190, dated December 21, 2011, that describes procedures for replacing or reworking the propeller pitch control assembly, incorporating a threaded hole in the splined end of the shouldered shaft, and reassembling the propeller pitch control assembly. 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 document. Costs of Compliance We estimate that this AD affects 360 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 or rework of the PPC 19 work-hours x $85 $1,000................. $2,615 $941,400 assembly. per hour = $1,615. Install secondary retention 1 work-hour x $85 10..................... 95 34,200 device. per hour = $85. Visual inspection of PPC lever... .5 work-hour x $85 Not applicable......... 42.50 15,300 per hour = $42.50. ---------------------------------------------------------------------------------------------------------------- We estimate the following costs to do any necessary adjustments that would be required based on the results of the visual inspection. We have no way of determining the number of aircraft that might need these adjustments: On-Condition Costs ---------------------------------------------------------------------------------------------------------------- Cost per Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Correct attachment of the PPC lever.... .5 work-hour x $85 per Not applicable.............. $42.50 hour = $42.50. ---------------------------------------------------------------------------------------------------------------- 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
