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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) issued by the aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    There is a possibility that during a go around procedure with a 
flap system failed the stall warning and the stick pusher triggering 
angles are anticipated reducing the margin between the real angle of 
attack and the stick pusher triggering angle. If the stick pusher is 
activated at a low altitude the pilot may be not able to recover the 
airplane control. Since this condition affects flight safety, an 
immediate corrective action is required. Thus, sufficient reason 
exists to request compliance with this EAD in the indicated time 
limit without prior notice.

This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective February 27, 2009.
    We must receive comments on this AD by March 30, 2009.

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

SUPPLEMENTARY INFORMATION:

Discussion

    The AG[Ecirc]NCIA NACIONAL DE AVIA[Ccedil][Atilde]O CIVIL--BRAZIL, 
which is the aviation authority for Brazil, has issued EAD No.: 2009-
02-04, dated February 13, 2009 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    There is a possibility that during a go around procedure with a 
flap system failed the stall warning and the stick pusher triggering 
angles are anticipated reducing the margin between the real angle of 
attack and the stick pusher triggering angle. If the stick pusher is 
activated at a low altitude the pilot may be not able to recover the 
airplane control. Since this condition affects flight safety, an 
immediate corrective action is required. Thus, sufficient reason 
exists to request compliance with this EAD in the indicated time 
limit without prior notice.

You may obtain further information by examining the MCAI in the AD 
docket.

FAA's Determination and Requirements of the 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 issuing this AD because we 
evaluated all information provided by the State of Design Authority and 
determined the 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 have also required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the AD. These requirements take 
precedence over those copied from the MCAI.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because if 
the stick pusher is activated at a low altitude the pilot may not be 
able to recover the airplane control. Therefore, we determined that 
notice and opportunity for public comment before issuing this AD are 
impracticable and that good cause exists for making this amendment 
effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant

[[Page 8846]]

data, views, or arguments about this AD. Send your comments to an 
address listed under the ADDRESSES section. Include ``Docket No. FAA-
2009-0150; Directorate Identifier 2009-CE-010-AD'' at the beginning of 
your comments. We specifically invite comments on the overall 
regulatory, economic, environmental, and energy aspects of this AD. We 
will consider all comments received by the closing date and may amend 
this AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this 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 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 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.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2009-05-06 Empresa Brasileira de Aeronautica S.A. (EMBRAER): 
Amendment 39-15830; Docket No. FAA-2009-0150; Directorate Identifier 
2009-CE-010-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective February 
27, 2009.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Models EMB-500 airplanes, all serial 
numbers, equipped with the stall warning computer part number (P/N) 
C100106-1, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states: There is a possibility that during a go around procedure 
with a flap system failed the stall warning and the stick pusher 
triggering angles are anticipated reducing the margin between the 
real angle of attack and the stick pusher triggering angle. If the 
stick pusher is activated at a low altitude the pilot may be not 
able to recover the airplane control. Since this condition affects 
flight safety, an immediate corrective action is required. Thus, 
sufficient reason exists to request compliance with this EAD in the 
indicated time limit without prior notice.

Actions and Compliance

    (f) Unless already done, before further flight, incorporate into 
the airplane flight manual (AFM) the following procedures and 
limitations section revisions. You may insert a copy of this AD into 
the appropriate sections of the AFM to comply with the requirements 
of this AD.
    (1) Revise the AFM by adding Figure 1 of this AD to the 
Limitations section 2.30.
