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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above that would supersede an existing AD. 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 two events of aircraft being dispatched with the cargo
door opened without indication. In one of the events the aircraft took
off with the cargo door opened.
    The unsafe condition is a cargo door opening during flight, which
could result in reduced structural integrity and consequent rapid
decompression of the airplane. 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 September 17,
2009.

Discussion

    On April 17, 2007, we issued AD 2007-06-53, Amendment 39-15035 (72
FR 21088, April 30, 2007). That AD requires actions intended to address
an unsafe condition on the products listed above.
    The preamble to AD 2007-06-53 specifies that we consider the
requirements ``interim action'' and that the manufacturer is developing
a modification to address the unsafe condition. That AD explains that
we might consider further rulemaking if a modification is developed,
approved, and available. The manufacturer now has developed such a
modification, and we have determined that further rulemaking is indeed
necessary; this proposed AD follows from that determination.
    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC),
which is the aviation authority for Brazil, has issued Brazilian
Airworthiness Directives 2007-03-01R1, effective June 9, 2008, and
2007-03-02R2, effective November 21, 2008 (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 two events of aircraft being
dispatched with the cargo door opened without indication. In one of
the events the aircraft took off with the cargo door opened.

The unsafe condition is a cargo door opening during flight, which could
result in reduced structural integrity and consequent rapid
decompression of the airplane. Required actions include repetitive
inspections of the forward and aft cargo doors to detect signs of
interference between the lock handle and the aft edge liner assembly
and reworking the assembly; a one-time inspection for signs of damage
of the lateral roller fitting on the forward and aft cargo door frames
at the fuselage and

[[Page 41643]]

replacement of the roller if necessary, and modification of the cargo
door, which ends the repetitive inspections. After accomplishing the
modification, the actions include incorporating information into the
maintenance program to include the operational (OPC) and functional
(FNC) checks of the forward and aft cargo doors and accomplishing
repetitive OPC and FNC checks. You may obtain further information by
examining the MCAI in the AD docket.

Relevant Service Information

    Embraer has issued Alert Service Bulletins 170-52-A036 (for Model
ERJ 170 airplanes) and 190-52-A018 (for Model ERJ 190 airplanes); both
Revision 01, both dated March 23, 2007. Embraer Alert Service Bulletins
170-52-A036 and 190-52-A018, both dated March 12, 2007, were referred
to in the existing AD for accomplishing the required actions. No
additional work is necessary for airplanes on which the original issue
of the service information has been done.
    Embraer has also issued Service Bulletins 170-52-0041, Revision 01,
dated June 13, 2008, and 170-52-0044, dated January 18, 2008 (for Model
ERJ 170 airplanes); and Service Bulletins 190-52-0023, Revision 02,
dated March 11, 2008, and 190-52-0027 dated March 20, 2008 (for Model
ERJ 190 airplanes).
    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 145 products of U.S. registry.
    The actions that are required by AD 2007-06-53 and retained in this
proposed AD take about 1 work-hour per product, at an average labor
rate of $80 per work hour. Based on these figures, the estimated cost
of the currently required actions is $80 per product.
    We estimate that it would take about 7 work-hours per product to
comply with the new basic requirements of this proposed AD. The average
labor rate is $80 per work-hour. Required parts would cost about
$17,162 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 the
proposed AD on U.S. operators to be $2,569,690, or $17,722 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 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.

Subject

    (d) Air Transport Association (ATA) of America Code 52: Doors.

[[Page 41644]]

Reason

    (e) The mandatory continuing airworthiness information (MCAI)
states:
    It has been found the occurrence of two events of aircraft being
dispatched with the cargo door opened without indication. In one of
the events the aircraft took off with the cargo door opened.

The unsafe condition is a cargo door opening during flight, which
could result in reduced structural integrity and consequent rapid
decompression of the airplane. Required actions include repetitive
inspections of the forward and aft cargo doors to detect signs of
interference between the lock handle and the aft edge liner assembly
and reworking the assembly; a one-time inspection for signs of
damage of the lateral roller fitting on the forward and aft cargo
door frames at the fuselage and replacement of the roller if
necessary, and modification of the cargo door, which ends the
repetitive inspections. After accomplishing the modification, the
actions include incorporating information into the maintenance
program to include the operational (OPC) and functional (FNC) checks
of the forward and aft cargo doors and accomplishing repetitive OPC
and FNC checks.

Compliance

    (f) Required as indicated, unless accomplished previously.

Restatement of Requirements of AD 2007-06-53, With New Service
Information

Preflight Verification of Correct Door Closure

    Note 4: For the purposes of this AD, a functional check (FNC)
is: ``A quantitative check to determine if one or more functions of
an item perform within specified limits.''

    Note 5: For the purposes of this AD, an operational check (OPC)
is: ``A task to determine if an item is fulfilling its intended
purpose. Since it is a failure finding task, it does not require
quantitative tolerances.''

FAA AD Differences

    Note 6: This AD differs from the MCAI and/or service information
as follows: Where the MCAI includes a compliance time of ``after
accomplishment of the modification'' for revising the maintenance
program for Model ERJ-170 airplanes, we have determined that a
compliance time of ``within 12 months after the effective date of
the AD or within 12 months after accomplishment of the modification,
whichever occurs later'' is appropriate. This compliance time is
equivalent to the compliance time required for Model ERJ-190
airplanes. The manufacturer and ANAC agree with this compliance
time.

Other FAA AD Provisions
