2015-30224. Airworthiness Directives; Embraer S.A. Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 170 airplanes; and all 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 cracks in certain engine low-stage bleed check valves. This proposed AD would require replacing the air management system (AMS) controller operation program of the AMS controller processor boards, and replacement of the current low-stage bleed check valve and associated seals. We are proposing this AD to prevent failure of the low-stage bleed check valve, which could result in dual engine in-flight shutdown.

DATES:

We must receive comments on this proposed AD by January 14, 2016.

Discussion

The Agência Nacional de Aviação Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2015-02-02, dated March 6, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. The MCAI states:

This [Brazilian] AD was prompted by reports of cracks in some engine low-stage bleed check valves having part number (P[/]N) 1001447-6. Further analysis has determined that if a new (zero hour) low-stage bleed check valve P/N 1001447-6 is installed in an airplane already equipped with the Air Management System (AMS) controller processor boards containing the AMS Controller Operational Program version Black Label 13, or a later version, premature cracking on the petals of the low-stage bleed check valve is not expected to occur. We are issuing this [Brazilian] AD to prevent the possibility of a dual engine in-flight shutdown due to low-stage bleed check valve failure.

The required action is replacement of the AMS controller operation program of the AMS controller processor boards, and replacement of the low-stage bleed check valves and associated seals. 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-2015-6542.

Related Service Information Under 1 CFR Part 51

Embraer has issued Service Bulletin 190-36-0023, Revision 03, dated September 24, 2014, which describes procedures for replacing the engine low-stage bleed check valves. Embraer has also issued Service Bulletin 190-21-0041, Revision 02, dated July 30, 2013, which describe procedures for replacing the AMS controller operation program of the AMS controller processor boards. 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 of this NPRM.

Differences Between the MCAI and This Proposed AD

The applicability of paragraph (g) of this proposed AD is limited to airplanes identified in Embraer Service Bulletin 190-21-0041, Revision 02, dated July 30, 2013. The MCAI did not include this limitation. We have included this limitation because Model ERJ 190 airplanes with serial number (S/N) 19000587, S/N 19000589, S/N 19000593 and subsequent have a modification incorporated at the factory equivalent to the modification required by this AD.

Also, this proposed AD includes all Embraer S.A. Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, and -200 STD airplanes, because of an additional proposed requirement in paragraph (j)(1) of this AD, which is related to installation of used low-stage bleed check valves having P/N 001447-6 on Model ERJ 170 airplanes. ANAC is considering future rulemaking to include a similar requirement.

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 our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.

Costs of Compliance

We estimate that this proposed AD affects 197 airplanes of U.S. registry.

We also estimate that it would take about 4 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $638 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $192,666, or $978 per product.

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 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. 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.
