Therefore, following a possible VerDate Aug<31>2005 failure on one FGCS channel during a given flight, such a failure condition will remain undetected or latent in subsequent flights. If another failure occurs on the second FGCS channel, the result may be a command hardover by the autopilot. The MCAI for Model ERJ 190 airplanes states: It has been found that some ‘‘caution’’ messages issued by the Flight Guidance Control System (FGCS) are not displayed on aircraft equipped with EPIC software load 4.3, 4.4 or 4.5. Therefore, following a possible failure on one FGCS channel during a given flight, such a failure condition will remain undetected or latent in subsequent flights. If another failure occurs on the second FGCS channel, the result may be a command hardover by the autopilot. A command hardover is a sudden roll, pitch, or yaw movement, which could result in reduced controllability of the airplane. The MCAI mandates a functional test of the flight guidance control system channels engagement. The corrective action is replacement of the actuator input-output processor if necessary. 60595 Note 2: This AD differs from the MCAI and/or service information as follows: We have provided optional terminating action in paragraph (f)(2) of this AD; this difference ˆ has been coordinated with the Agencia Nacional de Aviacao Civil (ANAC). ¸˜ Other FAA AD Provisions (g) The following provisions also apply to this AD: Airworthiness Directives; Empresa Brasileira de Aeronautica S.A.

Discussion ˆ The Agencia Nacional de Aviacao ¸˜ Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2006–09–03R1, effective January 4, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: It has been found the occurrence of engine anti-ice system valve failure, where the valve spring seat has broken and obstructed the anti-ice system venturi tube. Aircraft dispatch with that failure may be allowed by the operator Minimum Equipment List (MEL), since the engine anti-ice system valve be locked in the OPEN position. However, there is no readily available means to make sure the anti-ice system tubing is free of debris, allowing unrestricted hot airflow to the piccolo tube on the engine inlet lip. Therefore, should the aircraft encounter icing conditions, ice may accrete in the engine inlet lip and be ingested through the air inlet, resulting in possible engine damage and flame-out. The MCAI requires inspection of the engine anti-icing system valves and tubes to detect damage and, if necessary, replacement of the anti-icing system valves. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information EMBRAER has issued the following service bulletins: • 145–30–0044, Revision 03, dated December 12, 2006. • 145–30–0049, Revision 01, dated October 19, 2006. • 145LEG–30–0016, Revision 01, dated February 5, 2007. • 145LEG–30–0018, Revision 02, dated December 12, 2006. PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 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. 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 proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 697 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the requirements of this proposed AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $111,520, or $160 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 E:\FR\FM\25OCP1.SGM 25OCP1 Federal Register / Vol. 72, No. 206 / Thursday, October 25, 2007 / Proposed Rules 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. Applicability (c) This AD applies to Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB–135BJ, –135ER, –135KE, –135KL, –135LR, –145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes, certificated in any category, except aircraft having serial numbers 14500921, 14500928, 14500932, 14500949, 14500958, 14500971, 14500973 and up, which will have in-factory modification incorporated. Regulatory Findings Subject (d) Air Transport Association of America Code 30: Ice and Rain Protection. 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.

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 occurrence of engine anti-ice system valve 
failure, where the valve spring seat has broken and obstructed the 
anti-ice system venturi tube. * * *
    Therefore, should the aircraft encounter icing conditions, ice 
may accrete in the engine inlet lip and be ingested through the air 
inlet, resulting in possible engine damage and flame-out.

    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 November 26, 
2007.

Discussion

    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian 
Airworthiness Directive 2006-09-03R1, effective January 4, 2007 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    It has been found the occurrence of engine anti-ice system valve 
failure, where the valve spring seat has broken and obstructed the 
anti-ice system venturi tube. Aircraft dispatch with that failure 
may be allowed by the operator Minimum Equipment List (MEL), since 
the engine anti-ice system valve be locked in the OPEN position. 
However, there is no readily available means to make sure the anti-
ice system tubing is free of debris, allowing unrestricted hot 
airflow to the piccolo tube on the engine inlet lip. Therefore, 
should the aircraft encounter icing conditions, ice may accrete in 
the engine inlet lip and be ingested through the air inlet, 
resulting in possible engine damage and flame-out.

    The MCAI requires inspection of the engine anti-icing system valves 
and tubes to detect damage and, if necessary, replacement of the anti-
icing system valves. You may obtain further information by examining 
the MCAI in the AD docket.

Relevant Service Information

    EMBRAER has issued the following service bulletins:
     145-30-0044, Revision 03, dated December 12, 2006.
     145-30-0049, Revision 01, dated October 19, 2006.
     145LEG-30-0016, Revision 01, dated February 5, 2007.
     145LEG-30-0018, Revision 02, dated December 12, 2006.
    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.

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 proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 697 products of U.S. registry. We also estimate that 
it would take about 2 work-hours per product to comply with the 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $111,520, or $160 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

[[Page 60597]]

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.

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-
2007-0083; Directorate Identifier 2006-NM-266-AD.

Comments Due Date

    (a) We must receive comments by November 26, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Empresa Brasileira de Aeronautica S.A. 
(EMBRAER) Model EMB-135BJ, -135ER, -135KE, -135KL, -135LR, -145, -
145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes, 
certificated in any category, except aircraft having serial numbers

and up, which will have in-factory modification incorporated.

Subject

    (d) Air Transport Association of America Code 30: Ice and Rain 
Protection.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    It has been found the occurrence of engine anti-ice system valve 
failure, where the valve spring seat has broken and obstructed the 
anti-ice system venturi tube. Aircraft dispatch with that failure 
may be allowed by the operator Minimum Equipment List (MEL), since 
the engine anti-ice system valve be locked in the OPEN position. 
However, there is no readily available means to make sure the anti-
ice system tubing is free of debris, allowing unrestricted hot 
airflow to the piccolo tube on the engine inlet lip. Therefore, 
should the aircraft encounter icing conditions, ice may accrete in 
the engine inlet lip and be ingested through the air inlet, 
resulting in possible engine damage and flame-out.
    The MCAI requires inspection of the engine anti-icing system 
valves and tubes to detect damage and, if necessary, replacement of 
the anti-icing system valves.

is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''


    Note 2: For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''


    Note 3: For the purposes of this AD, a special detailed 
inspection is: ``An intensive examination of a specific item, 
installation, or assembly to detect damage, failure, or 
irregularity. The examination is likely to make extensive use of 
specialized inspection techniques and/or equipment. Intricate 
cleaning and substantial access or disassembly procedure may be 
required.''
