Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This proposed AD was prompted by Start Printed Page 17462reports of “BLEED 1(2) LEAK” messages displayed on the Engine Indication and Crew Alert System (EICAS), and indirect damage to components of the Electrical Wiring Interconnection System (EWIS) in the engine pylon area. This proposed AD would require inspecting the EWIS components for damage, and repair if necessary. This proposed AD would also require installing pre-cooler deflectors on the left- and right-hand pylons, and applying silicone sealant. We are proposing this AD to prevent indirect damage to EWIS components near the engine bleed air pre-coolers, which could result in a dual engine roll back to idle and consequent dual engine power loss and reduced controllability of the airplane.

DATES:

We must receive comments on this proposed AD by May 12, 2014.

Discussion

The Agência Nacional de Aviação Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2013-11-01, effective November 4, 2013 (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 170 airplanes. The MCAI states:

This [ANAC] AD results from reports of “BLEED 1(2) LEAK” messages being displayed on the Engine Indication and Crew Alert system (EICAS) panel, and indirect damages to components of the Electrical Wiring Interconnection System (EWIS) on the engine pilone area, zones 419 and 429, adjacent to the exhaust flange of the engine bleed air precooler.

Further investigation has shown that a leakage on the flange of the precooler refrigerating air exhaust duct caused the damage and triggered the message. We are issuing this [ANAC] AD to prevent EWIS components indirect damage, near to engine bleed air precooler, which could result in a dual engine roll back to idle and the consequent dual engine power loss.

Required actions include inspecting the EWIS components adjacent to the left- and right-hand pre-cooler for damage, and repair if necessary; installing pre-cooler deflectors on the left- and right-hand pylons, and applying silicone sealant. 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-2014-0172.

Relevant Service Information

Embraer has issued EMBRAER Service Bulletin 170-36-0019, dated August 23, 2011; and Subject 20-62-00, “Requirements for EWIS Components Inspections and Checks—Maintenance Practices” of EMBRAER 170/175/190/195 Standard Wiring Practices Manual SWPM-1590, Revision 25, dated June 3, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

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 would affect 181 products of U.S. registry.

We also estimate that it would take about 6 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 $366 per product. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $158,556, or $876 per product.

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed 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 Start Printed Page 17463detail 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.
