2010-16182. Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170 and ERJ 190 Airplanes

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI for EMBRAER Model ERJ 170 airplanes describes the unsafe condition as:

It has been found the occurrence of an engine in-flight shutdown caused by the LPCV [low pressure check valves] failing to close due to excessive wear, which leads to the concern that such fault may be present in both engines of a given aircraft.

* * * * *

The MCAI for EMBRAER Model ERJ 190 airplanes describes the unsafe condition as:

An occurrence of an uncommanded engine in-flight shutdown (IFSD) was reported * * *, which was caused by an ERJ 170 defective LPCV * * *. The valve failed to close due to excessive wear. Despite there were no IFSD related to LPCV * * * failure, some ERJ 190 valves * * * were inspected and presented cracks due to low cycle fatigue. Since this failure mode also might lead to an engine in-flight shutdown and since both engines of the airplane have the same valves, there is a possibility of an occurrence of a dual engine IFSD due to LPCV failure.

* * * * *

We are issuing this AD to require actions to correct the unsafe condition on these products.

DATES:

This AD becomes effective August 26, 2010.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 26, 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. That NPRM was published in the Federal Register on March 4, 2010 (75 FR 9816), and proposed to supersede AD 2007-16-09, Amendment 39-15148 (72 FR 44734, August 9, 2007). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI for EMBRAER Model ERJ 170 airplanes states:

It has been found the occurrence of an engine in-flight shutdown caused by the LPCV [low pressure check valves] failing to close due to excessive wear, which leads to the concern that such fault may be present in both engines of a given aircraft.

* * * * *

The MCAI for EMBRAER Model ERJ 190 airplanes states:

An occurrence of an uncommanded engine in-flight shutdown (IFSD) was reported on 20 Sep. 2005, which was caused by an ERJ 170 defective LPCV [part number] P/N 1001447-3 logging 3900 Flight Hours (FH). The valve failed to close due to excessive wear. Despite there were no IFSD related to LPCV P/N 1001447-4 failure, some ERJ 190 valves P/N 1001447-4 logging around 2472 FH were inspected and presented cracks due to low cycle fatigue. Since this failure mode also might lead to an engine in-flight shutdown and since both engines of the airplane have the same valves, there is a possibility of an occurrence of a dual engine IFSD due to LPCV failure.

* * * * *

The required actions include repetitive replacements of the low-stage check valves and associated seals of the left-hand and right-hand engine bleed system with new or serviceable valves, depending on the model. For certain airplanes, this AD also includes an optional terminating action for the repetitive replacements. This AD also requires, if the terminating action is done, revising the approved maintenance plan to include repetitive functional tests of the low-stage check valve. For certain other airplanes, this AD requires replacing a certain low-stage check valve with an improved low-stage check valve. 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 considered the comment received. The Air Line Pilots Association, International (ALPA), supports the NPRM.

Explanation of Change Made to This AD

Since we issued the NPRM, we have received Revision 6, of EMBRAER 170 Maintenance Review Board Report (MRBR), MRB-1621, dated January 14, 2010. We have updated the final rule to reference EMBRAER 170 Maintenance Review Board Report (MRBR), MRB-1621, Revision 6, dated January 14, 2010. We have added paragraph (j)(14) to this final rule to give credit for revising the maintenance program to include maintenance Task 36-11-02-002 (Low Stage Bleed Check Valve) specified in Section 1 of the EMBRAER 170 Maintenance Review Board Report (MRBR), MRB-1621, Revision 5, dated November 5, 2008.

We also revised paragraph (j)(13) of this AD to clarify that doing a replacement before the effective date of this AD is acceptable for compliance with a replacement specified in paragraph (j)(1) of this AD.

Conclusion

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will not increase the economic burden on any operator or increase the scope of the AD.

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD.

Costs of Compliance

We estimate that this AD will affect about 231 products of U.S. registry.

The actions that are required by AD 2007-16-09 and retained in this AD, which are provided in the following table, provide the estimated costs, at an average labor rate of $85 per work hour, for U.S. operators to comply with this AD. The parts manufacturer states that it will supply required parts to operators at no cost.

Estimated Costs

Action	Work hours	Cost per airplane	Number of U.S.-registered airplanes	Fleet cost
Replacement of right-hand check valves on Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes	3	$255 per replacement cycle	55	$14,025 per replacement cycle.
Replacement of left-hand check valves on Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes	3	$255 per replacement cycle	75	$19,125 per replacement cycle.

We estimate that it will take about 6 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $4,219 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $1,092,399, or $4,729 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 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 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); 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.

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, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone [phone]) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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.

§ 39.13

[Amended]

2. The FAA amends § 39.13 by removing Amendment 39-15148 ( 72 FR 44734, August 9, 2007) and adding the following new AD:

2010-14-14 Empresa Brasileira de Aeronautica S.A. (EMBRAER): Amendment 39-16359. Docket No. FAA-2010-0174; Directorate Identifier 2009-NM-186-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective August 26, 2010.

Affected ADs

(b) This AD supersedes AD 2007-16-09, Amendment 39-15148.

Applicability

(c) This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.

(1) Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; and Model ERJ 170-200 LR, -200 STD, and -200 SU airplanes; equipped with Hamilton Sundstrand low pressure check valve (LPCV) having part number (P/N) 1001447-3.

(2) Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 190-100 ECJ, -100 LR, -100 IGW, -100 STD airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes; equipped with Hamilton Sundstrand LPCV having P/N 1001447-3 or 1001447-4.

Subject

(d) Air Transport Association (ATA) of America Code 36: Pneumatic.

Reason

(e) The mandatory continuing airworthiness information (MCAI) for EMBRAER Model ERJ 170 airplanes states:

It has been found the occurrence of an engine in-flight shutdown caused by the LPCV [low pressure check valves] failing to close due to excessive wear, which leads to the concern that such fault may be present in both engines of a given aircraft.

* * * * *

The MCAI for EMBRAER Model ERJ 190 airplanes states:

An occurrence of an uncommanded engine in-flight shutdown (IFSD) was reported on 20 Sep. 2005, which was caused by an ERJ 170 defective LPCV P/N 1001447-3 logging 3,900 Flight Hours (FH). The valve failed to close due to excessive wear. Despite there were no IFSD related to LPCV P/N 1001447-4 failure, some ERJ 190 valves P/N 1001447-4 logging around 2472 FH were inspected and presented cracks due to low cycle fatigue. Since this failure mode also might lead to an engine in-flight shutdown and since both engines of the airplane have the same valves, there is a possibility of an occurrence of a dual engine IFSD due to LPCV failure.

* * * * *

The required actions include repetitive replacements of the low-stage check valves and associated seals of the left-hand and right-hand engine bleed system with new or serviceable valves, depending on the model. For certain airplanes, this AD also includes an optional terminating action for the repetitive replacements. This AD also requires, if the terminating action is done, revising the approved maintenance plan to include repetitive functional tests of the low-stage check valve. For certain other airplanes, this AD requires replacing a certain low-stage check valve with an improved low-stage check valve.
