Airworthiness Directives; M7 Aerospace LLC Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: This AD is effective June 15, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 15, 
2016.

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 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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (81 FR 11469, March 4, 2016) for correcting the unsafe condition; 
and
    <bullet> 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 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.
