2013-15637. Airworthiness Directives; Embraer S.A. Airplanes

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding airworthiness directive (AD) 2010-14-14 that applies to certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. AD 2010-14-14 currently requires, for certain airplanes, repetitively replacing the low-stage check valve and associated seals of the right hand (RH) engine's engine bleed system with a new check valve and new seals, replacing the low pressure check valves (LPCVs), and revising the maintenance program. For certain other airplanes, AD 2010-14-14 requires replacing a certain low-stage check valve with an improved low-stage check valve. For certain airplanes, this new AD adds replacing certain LPCVs of the left hand (LH) and RH engines, which would be an option for other airplanes. This AD was prompted by reports of uncommanded engine shutdowns on both Model ERJ 170 and ERJ 190 airplanes due to excessive wear and failure of LPCVs having certain part numbers. We are issuing this AD to prevent the possibility of a dual engine in-flight shutdown due to LPCV failure.

DATES:

This AD becomes effective August 6, 2013.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 6, 2013.

The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of August 26, 2010 (75 FR 42585, July 22, 2010).

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. The NPRM was published in the Federal Register on December 26, 2012 (77 FR 75911), and proposed to supersede AD 2010-14-14, Amendment 39-16359 (75 FR 42585, July 22, 2010). (AD 2010-14-14 superseded AD 2007-16-09, Amendment 39-15148 (72 FR 44734, August 9, 2007)). AD 2007-16-09 superseded AD 2005-23-14, Amendment 39-14372 (70 FR 69075, November 14, 2005). The NPRM proposed to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (MCAI) for Embraer S.A. Model ERJ 170 airplanes states:

It has been found the occurrence of an engine in-flight shutdown * * * caused by the LPCV failure P/N [part number] 1001447-3 with 3,900 Flight Hours (FH) installed on ERJ-170. This valve failed [to] open due [to] excessive wear. [I]t was found the occurrence of an engine shutdown on-ground, caused by the LPCV failure P/N 1001447-4 with 1,802 FH installed on ERJ-190 failed due [to] low cycle fatigue. Since the behavior of a valve P/N 1001447-4 removed from ERJ-190 is unknown on ERJ-170 and the P/N 1001447-4 is common between ERJ-170 and ERJ-190 airplane fleet, an action is necessary to prevent the installation, in ERJ-170 airplanes, of LPCVs P/N 1001447-4 previously installed in ERJ-190 airplanes.

The MCAI for Embraer S.A. Model ERJ 190 airplanes states:

It has been found the occurrence of an engine in-flight shutdown * * * caused by the LPCV failure P/N 1001447-3 with 3,900 Flight Hours (FH) installed on ERJ-170. This valve failed [to] open due [to] excessive wear. [I]t was found the occurrence of an engine shutdown on-ground, caused by the LPCV failure P/N 1001447-4 with 1,802 FH installed on ERJ-190 failed due [to] low cycle fatigue. Since the behavior of a valve P/N 1001447-4 removed from ERJ-170 is unknown on ERJ-190 and the P/N 1001447-4 is common between ERJ-170 and ERJ-190 airplane fleet, an action is necessary to prevent the installation, in ERJ-190 airplanes, of LPCVs P/N 1001447-4 previously installed in ERJ-170 airplanes.

* * * * *

The unsafe condition is the possibility of a dual engine in-flight shutdown due to LPCV failure. The required actions include the actions required by AD 2010-14-14, Amendment 39-16359 (75 FR 42585, July 22, 2010), and, for certain airplanes, replacing the LPCVs of the LH and RH engines, which would be an option for certain other airplanes. You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We have considered the comment received.

Request for Clarification of Approved Method

US Airways requested clarification of paragraph (l) of the NPRM (77 FR 75911, December 26, 2012), which requires installing a new LPCV using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or Agência Nacional de Aviação Civil (ANAC) (or its delegated agent). The commenter requested clarification of the approved method so operators can understand acceptable and unacceptable methods of installation. The commenter also stated that the approved method needs to be stated to avoid having to obtain approval of an alternative method of compliance (AMOC) allowing use of certain documents.

We agree to provide clarification. We have reviewed EMBRAER Service Bulletins 190-36-0014, Revision 01, dated January 14, 2009; 190-LIN-36-0004, dated December 23, 2009; and 170-36-0011, Revision 2, dated July 19, 2007. Those bulletins provide instructions for installing P/N 1001447-4; however, they may be used to install P/N 1001447-6. We have added paragraphs (l)(2) and (m)(2) to this AD to provide references for installing P/N 1001447-6. We have also added note 1 to paragraph (n) of this AD to provide guidance for an optional terminating action. Embraer has not published installation instructions specifically for the P/N 1001447-6 that can be incorporated by reference in this AD. We will consider approving any alternate installation instructions that operators propose.

Clarification of Calculation for Equivalent Flight Hours

We have revised paragraph (k)(4)(ii) of this AD to clarify the calculation for equivalent flight hours.

Conclusion

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (77 FR 75911, December 26, 2012) for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 75911, December 26, 2012).

Costs of Compliance

We estimate that this AD will affect about 253 products of U.S. registry.

We estimate the following costs to comply with this proposed AD:

Estimated costs

Action	Labor cost	Cost per product	Number of U.S.-registered airplanes	Cost on U.S. operators
Replacement of RH check valves on Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes (retained actions from AD 2010-14-14 (75 FR 42585, July 22, 2010))	3 work-hours × $85 per hour = $255 per replacement cycle	$255 per replacement cycle	55	$14,025 per replacement cycle.
Replacement of LH check valves on Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes (retained actions from AD 2010-14-14 (75 FR 42585, July 22, 2010))	3 work-hours × $85 per hour = $255 per replacement cycle	$255 per replacement cycle	75	$19,125 per replacement cycle.
Replacement of LPCVs with P/N 1001447-6 (new action)	2 work-hours × $85 per hour = $170	$170	253	$43,010.
Revision of maintenance program (new action)	1 work-hour × $85 per hour = $85	$85	253	$21,505.

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 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. 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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM (77 FR 75911, December 26, 2012), the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone [phone]) is in the ADDRESSES section.
