AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This proposed AD was prompted by reports of structural cracks in the wing lower skin stringers on both half wings. This proposed AD would require repetitive inspections of the lower skin stringers on both half wings for cracking or fuel leakage, and applicable related investigative and corrective actions, as specified in an Agência Nacional de Aviação Civil (ANAC) Brazilian AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.

Discussion

The ANAC, which is the aviation authority for Brazil, has issued Brazilian AD 2019-06-01, effective June 17, 2019 (“Brazilian AD 2019-06-01”) (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 IGW, -200 STD, -200 LR, and -200 IGW airplanes. The MCAI states:

It has been found the occurrence of structural cracks in the wing lower skin stringers between ribs 7 and 10 on both half wings. The cracks propagation on these wing lower skin stringers may result in fuel leakage and reduced wing structural integrity.

Since this condition may occur in other airplanes of the same type and affects flight safety, [related investigative and] a corrective action is required. Thus, sufficient reason exists to request compliance with this [Brazilian] AD in the indicated time limit.

Related IBR Material Under 1 CFR Part 51

Brazilian AD 2019-06-01 describes procedures for repetitive detailed inspections of the lower skin stringers on both half wings for cracking or fuel leakage, and applicable related investigative and corrective actions. Related investigative actions include a high frequency eddy current (HFEC) inspection of any area with crack indications to confirm the damage extension. Corrective actions include repairs. 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.

FAA's Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to a bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD because the agency evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.

Proposed AD Requirements

This proposed AD would require accomplishing the actions specified in Brazilian AD 2019-06-01 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD.

Explanation of Required Compliance Information

In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and the European Aviation Safety Agency (EASA) to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, Brazilian AD 2019-06-01 would be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with Brazilian AD 2019-06-01 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information specified in Brazilian AD 2019-06-01 that is required for compliance with Brazilian AD 2019-06-01 will be available on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2019-0701 after the FAA final rule is published.

Costs of Compliance

The FAA estimates that this proposed AD affects 29 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:

The FAA estimates the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition actions:

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 proposed 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:

(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.

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39—AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD):

Embraer S.A: Docket No. FAA-2019-0701; Product Identifier 2019-NM-107-AD.

(a) Comments Due Date

The FAA must receive comments by November 14, 2019.

(b) Affected ADs

None.

(c) Applicability

This AD applies to Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes, certificated in any category, as identified in Agência Nacional de Aviação Civil (ANAC) Brazilian AD 2019-06-01, effective June 17, 2019 (“Brazilian AD 2019-06-01”).

(d) Subject

Air Transport Association (ATA) of America Code 57, Wings.
