AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

The FAA is superseding Airworthiness Directive (AD) 2017-16-08, which applied to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, and -100 ECJ airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. AD 2017-16-08 required revising the existing maintenance or inspection program, as applicable, to incorporate more restrictive airworthiness limitations. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD also adds airplanes to the applicability. This AD was prompted by the FAA's determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective February 3, 2020.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 3, 2020.

The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of October 11, 2017 (82 FR 42021, September 6, 2017).

SUPPLEMENTARY INFORMATION:

Discussion

The Agência Nacional de Aviação Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian AD 2019-05-02, effective May 2, 2019; corrected July 1, 2019 (“Brazilian AD Start Printed Page 717732019-05-02”) (also referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 SR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. Model ERJ 190-100SR airplanes are not on the U.S. Register; this AD therefore does not include those airplanes in the applicability. You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2019-0519.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017-16-08, Amendment 39-18985 (82 FR 42021, September 6, 2017) (“AD 2017-16-08”). AD 2017-16-08 applied to certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ and -100 IGW airplanes and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. The NPRM published in the Federal Register on July 5, 2019 (84 FR 32101). The NPRM was prompted by the FAA's determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The NPRM also proposed to add airplanes to the applicability. The FAA is issuing this AD to address fatigue cracking of structural components and to address failure of certain system components, which could result in reduced structural integrity and system reliability of the airplane. See the MCAI for additional background information.

Action Since the NPRM Was Issued

Since the NPRM was issued ANAC published a correction to Brazilian AD 2019-05-02 to clarify that the initial compliance times identified as “Threshold” or “T” in EMBRAER 190/195 Maintenance Review Board Report, MRB-1928, Revision 12, dated September 27, 2018 (“EMBRAER 190/195 MRB-1928, Revision 12”), are expressed in total flight cycles and total flight hours. The FAA has revised paragraph (i)(1)(i) of this AD to state “For the purposes of this AD, the initial compliance times (identified as `Threshold' or `T' in EMBRAER 190/195 MRB-1928, Revision 12) are expressed in `total flight cycles' or `total flight hours,' as applicable.”

Comments

The FAA gave the public the opportunity to participate in developing this final rule. The following presents the comment received on the NPRM and the FAA's response to that comment.

Request for Credit for Previously Accomplished Actions

Embraer requested that operators be allowed to substitute the last accomplishment of task 53-23-001-0001, which was included in Revision 11 and earlier of EMBRAER 190/195 MRB-1928, for the initial accomplishment of task 53-53-001-0004, which is included in EMBRAER 190/195 MRB-1928, Revision 12. Embraer justified its request by providing a copy of Brazilian AMOC No. 632/2019/GCPR/GGCP/SAR-ANAC, dated June 13, 2019. The commenter explained that task 53-23-001-0004 was created for EMBRAER 190/195 MRB-1928, Revision 12, by splitting an existing task from previous revisions of EMBRAER 190/195 MRB-1928 in order to increase the interval for certain parts of the task, reducing the frequency of access in areas that are difficult to access. In EMBRAER 190/195 Maintenance Review Board Report, MRB-1928, Revision 11, and earlier, task 53-23-001-0001 included the same inspection as task 53-23-001-0004. ANAC granted Brazilian AMOC No. 632/2019/GCPR/GGCP/SAR-ANAC, dated June 13, 2019, to provide credit for a one time accomplishment of task 53-23-001-0001 as a substitution for the initial accomplishment of task 53-23-001-0004, provided the task was accomplished within 5,000 flight cycles since the last accomplishment.

The FAA agrees with the commenter's request for the reason provided and has included Brazilian AMOC No. 632/2019/GCPR/GGCP/SAR-ANAC, dated June 13, 2019, in paragraph (k)(1)(iii) of this AD to allow accomplishment of task 53-23-001-0001 after the effective date of this AD as a substitution for the initial accomplishment of task 53-23-001-0004, provided this task was accomplished within 5,000 flight cycles since it was last accomplished.

Conclusion

The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule with the change described previously and minor editorial changes. The FAA determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM.

The FAA also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule.

Related Service Information Under 1 CFR Part 51

Embraer has issued Appendix A—Airworthiness Limitations (AL), to the EMBRAER 190/195 Maintenance Review Board Report, MRB-1928, Revision 12, dated September 27, 2018.

Embraer has also issued Appendix A—Airworthiness Limitations (AL), to the EMBRAER Lineage 1000/1000E Maintenance Planning Guide, MPG-2928, Revision 8, dated October 10, 2018.

This AD also requires the following documents, which the Director of the Federal Register approved for incorporation by reference as of October 11, 2017 (82 FR 42021, September 6, 2017).

  • Appendix A—Airworthiness Limitations (AL), of the EMBRAER ERJ 190/195 Maintenance Review Board Report, MRB-1928, Revision 9, dated August 14, 2015.

This 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.

Costs of Compliance

The FAA estimates that this AD affects 107 airplanes of U.S. registry.

The FAA estimates the following costs to comply with this AD.

The actions that are required by AD 2017-16-08 and retained in this final rule take about 1 work-hour per product, at an average labor rate of $85 per work hour. Required parts cost about $0 per product. Based on these figures, the estimated cost of the actions that were required by AD 2017-16-08 is $85 per product.

The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 work-hours per operator, although the agency Start Printed Page 71774recognizes that this number may vary from operator to operator. In the past, the FAA has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the FAA estimates the total cost per operator to be $7,650 (90 work-hours × $85 per work-hour).

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.

The FAA is 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.

This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.

Regulatory Findings

The FAA 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) Will not affect intrastate aviation in Alaska, and

(3) 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.
