2020-08219. Airworthiness Directives; Yaborã Indústria Aeronáutica S.A. (Type Certificate Previously Held by Embraer S.A.) Airplanes

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for certain Yaborã Indústria Aeronáutica S.A. Model ERJ-170 airplanes and Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by a determination that certain main landing gear (MLG) aft pintle pins repaired using a sulphamate nickel plating have a life limit that is less than the certified life limit. This AD requires a one-time records review or a general visual inspection (GVI) of the MLG aft pintle pins to determine if certain repairs were done, and replacement of certain MLG aft pintle pins with serviceable MLG aft pintle pins, as specified in an Agência Nacional de Aviação Civil (ANAC) Brazilian AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective May 26, 2020.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 26, 2020.

SUPPLEMENTARY INFORMATION:

Discussion

The ANAC, which is the aviation authority for Brazil, has issued Brazilian AD 2019-11-07, effective November 18, 2019 (“Brazilian AD 2019-11-07”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Yaborã Indústria Aeronáutica S.A. Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; Model ERJ 170-200 LR, -200 SU, -200 STD, and -200 LL airplanes; and Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -100 SR, -200 STD, -200 LR, and -200 IGW airplanes. Model ERJ 190-100 SR airplanes are not certified by the FAA and are not included on the U.S. type certificate data sheet; this AD, therefore, does not include those airplanes in the applicability.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Yaborã Indústria Aeronáutica S.A. Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; Model ERJ 170-200 LR, -200 SU, -200 STD, and -200 LL airplanes; and Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. The NPRM published in the Federal Register on January 17, 2020 (85 FR 2909). The NPRM was prompted by a determination that certain MLG aft pintle pins repaired using a sulphamate nickel plating have a life limit that is less than the certified life limit. The NPRM proposed to require a one-time records review and a GVI of the MLG aft pintle pins to determine if certain repairs were done, and replacement of certain MLG aft pintle pins with serviceable MLG aft pintle pins, as specified in a Brazilian AD.

The FAA is issuing this AD to address failure of the affected MLG aft pintle pins before reaching the certified life limit, which could result in collapse of the MLG during takeoff or landing. See the MCAI for additional background information.

Explanation of Change to Manufacturer's Name

The FAA revised references to the manufacturer's name throughout this final rule to identify the manufacturer's name published in the most recent type certificate data sheet for the affected models.

Comments

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

Support for the NPRM

The Air Line Pilots Association, International (ALPA) expressed support for the NPRM.

Request To Allow Review of Maintenance Records

Horizon Air requested that the final rule provide the option for operators to perform a records review or physical inspection and only mandate a physical inspection of the part if the repair history of the pintle pin cannot conclusively be determined from the records review. The commenter noted that paragraph (h)(3) of the proposed AD proposed to require both a one-time records review and a general visual inspection of the MLG aft pintle pins to determine if certain repairs were done. The commenter explained that as a life limited part, documentation is required by the FAA, therefore a review of airplane maintenance records should be acceptable in lieu of this inspection if the part status can be conclusively determined from that review.

The FAA agrees with the commenter's request. The FAA has revised paragraph (h)(3) of this AD to allow operators to do a review of airplane maintenance records in lieu of an inspection if the repair history can be conclusively determined from that review. The FAA has also revised the SUMMARY of this final rule to reflect this allowance.

Conclusion

The FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorial changes. The FAA has 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 IBR Material Under 1 CFR Part 51

Brazilian AD 2019-11-07 describes procedures for a one-time records review (for documentation of certain repairs) and a GVI of the MLG aft pintle pins to determine if certain repairs were done (by checking for certain markings and part numbers), and replacement of certain MLG aft pintle pins with serviceable MLG aft pintle pins. This material 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 659 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Labor cost	Parts cost	Cost per product	Cost on U.S. operators
2 work-hours × $85 per hour = $170	* $	* $170	* $112,030
* The FAA has received no definitive data that would enable the agency to provide parts cost estimates for the replacements specified in this AD.

According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in the cost estimate.

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.

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) 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.

List of Subjects in 14 CFR Part 39

• Air transportation
• Aircraft
