[Docket No. FAA-2016-5431; Directorate Identifier 2015-CE-044-AD; 
Amendment 39-18593; AD 2016-15-02]

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 SA26-AT, SA26-T, 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. This AD was prompted by 
reports of multiple cracks in the steel horizontal tube of the cockpit 
control column. This AD requires inspection of the cockpit control 
column horizontal tube for cracks and repair or replacement of the 
cockpit control column as necessary. We are issuing this AD to correct 
the unsafe condition on these products.

DATES: This AD is effective August 26, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 26, 
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 
SA26-AT, SA26-T, 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 April 
1, 2016 (81 FR 18804). The NPRM was prompted by reports of multiple 
cracks in the cockpit control column horizontal tube at the corners of 
the access panel cutout, at the pulley bolt welds, and at the elevator 
arm weld in the steel horizontal tube of the control column on M7 
Aerospace SA26, SA226, and SA227 airplanes. The NPRM proposed to 
require inspection of the cockpit control column horizontal tube for 
cracks and repair or replacement of the cockpit control column as 
necessary. This condition, if not corrected, could result in partial or 
complete control column failure with partial or complete loss of pitch 
and/or roll control. 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. The following presents the comment received on the NPRM (81 FR 
18804, April 1, 2016) and the FAA's response to the comment.

Request for Previously Done Credit

    Michael O'Brien at Bearskin Airlines commented they had been 
complying with this AD by accomplishing the service bulletins that are 
listed in the proposed AD. He asked if it would be acceptable to just 
accomplish a technical records research to see when the required 
actions were last done.
    We agree that credit should be given for actions previously done 
with the service bulletins called out in the NPRM. The NPRM already 
allows for this with the phrase ``unless already done'' in paragraphs 
(g)(1) and (2) of the NPRM.
    Because the requested change is already part of this AD, we have 
not changed the final rule AD action based on this comment.

Conclusion

    We reviewed the relevant data, considered the comment received, 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:

[[Page 47695]]

     Are consistent with the intent that was proposed in the 
NPRM (81 FR 18804, April 1, 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 18804, April 1, 2016).

Related Service Information Under 1 CFR Part 51

    We reviewed M7 Aerospace LLC SA26 Series Service Bulletin (SB) 26-
27-002, M7 Aerospace LLC SA226 Series SB 226-27-078, M7 Aerospace LLC 
SA227 Series SB 227-27-058, and M7 Aerospace LLC SA227 Series SB CC7-
27-030, all dated October 8, 2015. The service information describes 
procedures for inspection of the cockpit control column horizontal tube 
for cracks and repair or replacement of the cockpit control column as 
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 NPRM.

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

                                hour = $1,020.
----------------------------------------------------------------------------------------------------------------

    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

                                        $1,360.
----------------------------------------------------------------------------------------------------------------

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.
