AD 2016-15-02

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.

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 completeloss 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 ---------------------------------------------------------------------------------------------------------------- Inspection................... 12 work-hours x $85 per Not applicable...... $1,020 $357,000
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 ----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Repair cracks........................ 2 work-hours x $85 per hour = Not applicable......... $170
$170. Replace parts........................ 16 work-hours x $85 per hour = $5,000................. 6,360
$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.
