AD 2016-10-01

We are adopting a new airworthiness directive (AD) for all M7 Aerospace LLC Models SA226-AT, SA226-T, 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. We received reports of failed elevator control rod ends due to corrosion and lack of lubrication. This AD requires initial and repetitive inspections and lubrication of the elevator control rod ends and bearings with replacement as necessary. We are issuing this AD to correct the unsafe condition on these products.

Final rule.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all M7 Aerospace LLC Models SA226-AT, SA226-T, 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 March 4, 2016 (81 FR 11469). The NPRM was prompted by reports of broken elevator control rod link assemblies between the elevator torque tube and the elevator quadrant due to corrosion and lack of lubrication on M7 Aerospace SA26, SA226, and SA227 airplanes. The NPRM proposed to require initial and repetitive inspections of the elevator control rod ends and bearings with replacement as necessary. 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 (81 FR 11469, March 4, 2016) 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 except for minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM (81 FR 11469, March 4, 2016) for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM (81 FR 11469, March 4, 2016).

Related Service Information Under 1 CFR Part 51

We reviewed M7 Aerospace Service Bulletin (SB) 226-27-080 R1, M7 Aerospace LLC SB 227-27-060 R1, and M7 Aerospace LLC SB CC7-27-032 R1, all Issued: November 5, 2015, and Revised: February 23, 2016. The service information describes procedures for inspection of the elevator control link assemblies between the elevator torque tubes and the elevator quadrant for frozen (stiff, hard to move) bearings or broken/ cracked links (rod ends) with instructions for lubrication and replacement if necessary. All of the related 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 350 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 ---------------------------------------------------------------------------------------------------------------- Inspection and lubrication........ 2 work-hours x $85 Not applicable....... $170 $59,500
per hour = $170. ----------------------------------------------------------------------------------------------------------------

We estimate the following costs to do any necessary repairs/ replacements that would be required based on the results of the inspection. We have no way of determining the number of airplanes that might need these repairs/replacements:

On-condition Costs ----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Replace Rod End............................ 4 work-hours x $85 per hour = $340. $30 $370 ----------------------------------------------------------------------------------------------------------------

Authority for This Rulemaking

Title 49 of the United States Code specifiesthe 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
