Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. 
(EMBRAER) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

[[Page 21161]]

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-
135BJ airplanes. This proposed AD was prompted by reports of failure of 
the bolts that connect the cockpit windshield center-post to the 
forward fuselage. This proposed AD would require repetitive detailed 
inspections to detect discrepancies on the attaching parts of the 
cockpit windshield center-post; checking whether the bolts are 
tightened, if applicable; and modifying parts, including inspecting for 
and repairing damage. The modification would terminate the repetitive 
inspections. We are proposing this AD to prevent failed bolts and 
failed attaching parts of the cockpit windshield center-post, which 
could lead to loss of structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by May 30, 2014.

Discussion

    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil, which is 
the aviation authority for Brazil, has issued Brazilian Airworthiness 
Directive 2013-10-02, dated October 23, 2013 (referred to after this as 
the Mandatory Continuing Airworthiness Information, or ``the MCAI''), 
to correct an unsafe condition for the specified products. The MCAI 
states:

    This [Brazilian] AD was prompted by reports of failure of the 
bolts that connect the lower eyelet fitting of the cockpit 
windshield center-post to the forward fuselage. We are issuing this 
[Brazilian] AD to detect failed bolts and correct the attaching 
parts of the lower eyelet fitting of the cockpit windshield center-
post, which could lead to loss of structural integrity of the 
airplane.

    Required actions include repetitive detailed inspections for 
discrepancies on the attaching parts of the lower eyelet fitting of the 
cockpit windshield center-post; a bolt check, if applicable; and 
modification of the attaching parts of the lower eyelet fitting of the 
cockpit windshield center-post, including a general visual inspection 
for damage of the specified lower eyelet fitting and repair of the 
damage. The modification would terminate the repetitive detailed 
inspections. You may examine the MCAI in the AD docket on the Internet 
at http://www.regulations.gov by searching for and locating it in 
Docket No. FAA-2014-0234.

Relevant Service Information

    EMBRAER has issued Service Bulletin 145LEG-53-A032, Revision 1, 
dated September 24, 2013. 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.
    In many FAA transport ADs, when the service information specifies 
to contact the manufacturer for further instructions if certain 
discrepancies are found, we typically include in the AD a requirement 
to accomplish the action using a method approved by either the FAA or 
the State of Design Authority (or its delegated agent).
    We have recently been notified that certain laws in other countries 
do not allow such delegation of authority, but some countries do 
recognize design approval organizations. In addition, we have become 
aware that some U.S. operators have used repair instructions that were 
previously approved by a State of Design Authority or a Design Approval 
Holder (DAH) as a method of compliance with this provision in FAA ADs. 
Frequently, in these cases, the previously approved repair instructions 
come from the airplane structural repair manual or the DAH repair 
approval statements that were not specifically developed to address the 
unsafe condition corrected by the AD. Using repair instructions that 
were not specifically approved for a particular AD creates the 
potential for doing repairs that were not developed to address the 
unsafe condition identified by the MCAI AD, the FAA AD, or the 
applicable service information, which

[[Page 21162]]

could result in the unsafe condition not being fully corrected.
    To prevent the use of repairs that were not specifically developed 
to correct the unsafe condition, this proposed AD would require that 
the repair approval specifically refer to the FAA AD. This change is 
intended to clarify the method of compliance and to provide operators 
with better visibility of repairs that are specifically developed and 
approved to correct the unsafe condition. In addition, we use the 
phrase ``its delegated agent, or the DAH with State of Design Authority 
design organization approval, as applicable'' in this proposed AD to 
refer to a DAH authorized to approve required repairs for this proposed 
AD.

Clarification of Requirements

    Brazilian Airworthiness Directive 2013-10-02, dated October 23, 
2013, specifies that for those airplanes identified in Group 1 of 
EMBRAER Service Bulletin 145LEG-53-A032, Revision 01, dated September 
24, 2013, that have done certain actions specified in EMBRAER Service 
Bulletin 145LEG-53-0021, dated June 8, 2005, and EMBRAER Service 
Bulletin 145LEG-53-0021, Revision 01, dated July 13, 2007, to do those 
actions at certain compliance times. For those actions, this AD 
specifies the affected airplanes as airplanes identified in Group 1 of 
EMBRAER Service Bulletin 145LEG-53-A032, Revision 01, dated September 
24, 2013, that have done the actions specified in any revision of 
EMBRAER Service Bulletin 145LEG-53-0021. This difference has been 
coordinated with the Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o 
Civil.

Costs of Compliance

    We estimate that this proposed AD affects 56 airplanes of U.S. 
registry.
    We also estimate that it would take about 35 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 $386 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $188,216, or $3,361 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
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 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);
    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.
