**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. The SNPRM published in the Federal Register on October 27, 2015 (80 FR 65666) (‘‘the SNPRM’’). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on October 16, 2012 (77 FR 63282) (‘‘the NPRM’’). The NPRM proposed to require revising the maintenance or inspection program to incorporate revised AWL tasks specified in certain technical requirements. The NPRM was prompted by the need for more stringent inspection requirements for certain affected components. The SNPRM proposed to require revising the maintenance or inspection program to incorporate certain revised AWL tasks instead of TRs, and to require repairs of affected components. We are issuing this AD to detect and correct fatigue cracking in the affected components. Such cracking could result in loss of structural integrity.

Transport Canada Civil Aviation (TCCA), which is the aviation authority


### 59840 Federal Register / Vol. 81, No. 169 / Wednesday, August 31, 2016 / Rules and Regulations

for Canada, has issued Canadian AD CF–2012–13, dated April 10, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. The MCAI

states:

A revision has been made to Part 2 of the Canadair Regional Jet Maintenance Requirements Manual (MRM), Airworthiness Limitations (AWL), to introduce more stringent inspection requirements forcontinued airworthiness based on reanalysis, in-service data and/or fatigue testing. Failure to comply with these revised AWL items could lead to an unsafe condition.

This [Canadian] AD is issued to ensure that fatigue cracking of these affected components [and consequent loss of airplane structural integrity] is detected and corrected.

Required actions include revising the maintenance program by incorporating the revised inspection requirements specified in certain TRs. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2012–

1075.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the SNPRM and the FAA’s response to each comment.
Request To Withdraw SNPRM

Mr. Aaron Ahern stated that the SNPRM must be denied and considered null and void. Mr. Ahern provided no justification for this statement.

From this statement, we infer that Mr. Ahern is requesting we withdraw the SNPRM. We disagree with the request. It is within our authority to issue ADs to require actions to address unsafe conditions that are not otherwise being addressed (or are not addressed adequately) by normal maintenance procedures. We may address such unsafe conditions by requiring revisions to maintenance or inspection programs as a condition under which airplanes may continue to be operated. We agree with TCCA’s finding of an unsafe condition based on analysis, in-service data, and/or fatigue testing. From the data gathered, we have determined that fatigue cracking is likely to exist or develop in certain components of the affected airplanes. As a result, we have determined that the actions required by this AD are necessary to address the identified unsafe condition. We have not changed this final rule in this regard. Request To Allow for Other Methods of Compliance

Air Wisconsin Airlines Corporation (Air Wisconsin) requested that we revise the proposed AD to allow qualified FAA representatives, such as Designated Engineering Representatives (DERs) and Organization Designation Authorization (ODA) holders, to approve repair methods. Air Wisconsin stated that 14 CFR 121.1109 (Supplemental Inspections) requires a certificate holder’s maintenance program to include FAA-approved damage tolerance inspections and procedures. Air Wisconsin pointed out that both DERs and ODAs already perform damage tolerance evaluations (DTEs).

We disagree. While we might authorize a design approval holder’s DERs to determine whether a design or repair method complies with a specific requirement of a structural AD, they are not authorized to make the discretionary determination of the applicable requirement. DERs are not authorized to approve repairs as alternative methods of compliance (AMOCs) to ADs, except under specific conditions described in FAA Orders 8110.103, 8100.15, and 8100.37. In addition, this AD already includes a provision for TCCA’s Design Approval Organization (DAO) to approve repairs. We have not changed this AD in this regard.
Request To Confirm Previously Approved Repairs

Air Wisconsin requested that we confirm whether repairs that may not have been incorporated per paragraphs (k)(2)(i), (k)(2)(ii), and (k)(2)(iii) of the proposed AD (in the SNPRM) are still considered approved for compliance to this AD under paragraph (k)(2) of the proposed AD (in the SNPRM).

We agree. As long as the previously approved repair meets the requirements of paragraphs (k)(2)(i), (k)(2)(ii), and (k)(2)(iii) of this AD, it does not matter when the repair is actually accomplished. We have clarified paragraph (k)(2)(i) of this AD to reflect this. In response to Air Wisconsin’s comment regarding this issue in the NPRM, we had included a provision in paragraph (k)(2)(i) of the proposed AD (in the SNPRM) to allow for previously approved repairs in the inspection area that were approved by the Manager, New York Aircraft Certification Office, ANE–170, FAA; or TCCA; or Bombardier, Inc.’s TCCA DAO, but that provision included the language ‘‘the repairs were accomplished.’’ We have removed that language from paragraph (k)(2)(i) of this AD. Request To Reference Revised Service Information

SkyWest Airlines (SkyWest) requested that we revise the SNPRM to reference the latest service information. SkyWest pointed out that Bombardier has issued Revision 10, dated May 10, 2015, of Part 2, Airworthiness Requirements, of the Bombardier CL–600–2B19 Maintenance Requirements Manual (MRM), CSP A–

053.

We agree to reference Bombardier Revision 10, dated May 10, 2015, of Part 2, Airworthiness Requirements, of the Bombardier CL–600–2B19 MRM, CSP A–053, as the appropriate source of service information for certain requirements of this AD. We have revised this final rule accordingly.
Request To Remove Requirement That Repair Approvals Refer to the MCAI

SkyWest requested that we remove the requirement that repair approvals must refer to the MCAI. SkyWest stated that leaving this paragraph in the AD would require SkyWest to request a large number of AMOCs for their fleet as soon as the AD becomes effective. SkyWest asserts that none of the repair engineering orders (REOs) and general repair engineering orders (GREOs) reference the MCAI, and do not have an inspection method.

We disagree with the request. We are aware of instances of repairs in an affected area that are signed by the foreign authority’s authorized delegate, but did not correct the unsafe condition because they were outdated. A repair that references the unsafe condition addressed in the MCAI guarantees an approved repair. A revised service document or AMOC that satisfies the requirements of paragraph (k)(2) of this AD is acceptable. We have not changed this AD in this regard.

Conclusion

We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the SNPRM for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the SNPRM.

We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

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

We determined that 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 the 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
