14 CFR Part 39

[Docket No. FAA-2010-0870; Directorate Identifier 2010-CE-045-AD]
RIN 2120-AA64

 
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. 
(EMBRAER) Model EMB-500 Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed 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 describes the unsafe 
condition as:

    It has been found the occurrences of failure of the Flow Control 
Shutoff Valve (FCSOV) in the closed position. Failure of the two 
valves (left and right) can cause the loss of the pneumatic source, 
and lead to loss of the cabin pressurization.
    Since this condition affects flight safety, a corrective action 
is required. Thus, sufficient reason exists to request compliance 
with this AD.

The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by October 18, 
2010.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    The AG[Ecirc]NCIA NACIONAL DE AVIA[Ccedil][Atilde]O CIVIL--BRAZIL 
(ANAC), which is the aviation authority for Brazil, has issued AD No. 
2010-08-01, dated September 3, 2010 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    It has been found the occurrences of failure of the Flow Control 
Shutoff Valve (FCSOV) in the closed position. Failure of the two 
valves (left and right) can cause the loss of the pneumatic source, 
and lead to loss of the cabin pressurization.
    Since this condition affects flight safety, a corrective action 
is required. Thus, sufficient reason exists to request compliance 
with this AD.

The MCAI requires replacing both FCSOVs with new and improved FCSOVs. 
You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Empresa Brasileira de Aeron[aacute]utica S.A. (EMBRAER) has issued 
Service Bulletin 500-21-0001, dated December 9, 2009. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed 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 proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are

[[Page 53610]]

highlighted in a Note within the proposed AD.

Costs of Compliance

    We estimate that this proposed AD will affect 79 products 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 $10,487 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $855,333, or $10,827 per product.
    According to Embraer, the parts cost of this proposed AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all cost in our cost 
estimate.

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); 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 proposed AD and placed it in the AD docket.

reference, Safety.

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.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Empresa Brasileira de Aeronautica S.A. (EMBRAER): Docket No. FAA-
2010-0870; Directorate Identifier 2010-CE-045-AD.

Comments Due Date

    (a) We must receive comments by October 18, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Embraer--Empresa Brasileira de 
Aeronautica S.A. (EMBRAER) Model EMB-500 airplanes, serial numbers 
50000005 through 50000118, 50000120, 50000122 through 50000126, 
50000128, and 50000131, certificated in any category.

Subject

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

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    It has been found the occurrences of failure of the Flow Control 
Shutoff Valve (FCSOV) in the closed position. Failure of the two 
valves (left and right) can cause the loss of the pneumatic source, 
and lead to loss of the cabin pressurization.
    Since this condition affects flight safety, a corrective action 
is required. Thus, sufficient reason exists to request compliance 
with this AD.

The MCAI requires replacing both FCSOVs with new and improved 
FCSOVs. You may obtain further information by examining the MCAI in 
the AD docket.

Actions and Compliance

    (f) Unless already done, at the next scheduled maintenance check 
or within 12 months after the effective date of this AD or within 
600 hours time-in-service after the effective date of this AD, 
whichever occurs first, replace both flow control shutoff valves, 
part number (P/N) 1300230-13 and P/N 1300230-23, with P/N 1300230-15 
and P/N 1300230-25. Do the replacements following Empresa Brasileira 
de Aeron[aacute]utica S.A. (EMBRAER) Service Bulletin 500-21-0001, 
dated December 9, 2009.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: No differences.
