Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER Model EMB-135BJ airplanes. This proposed AD would require inspecting for missing fire blocking material on the left- and right-hand partitions of the forward baggage compartment door; replacing the seal on both partitions; and performing corrective action if necessary. This proposed AD results from a report indicating that certain airplanes were delivered with the fire blocking material missing and the seal improperly installed on the partitions of the forward baggage compartment door. We are proposing this AD to detect and correct such discrepancies on the partitions of the forward baggage compartment door, which, in the event of a fire in the baggage compartment, could result in smoke propagating into the main cabin.
DATES: We must receive comments on this proposed AD by May 11, 2006.
ADDRESSES: Use one of the following addresses to submit comments on this proposed AD.

Discussion
The Departmento de Aviacao Civil (DAC), which is the airworthiness authority for Brazil, notified us that an unsafe condition may exist on certain EMBRAER Model EMB-135BJ airplanes. The DAC advises that certain airplanes were delivered with the fire blocking material missing and the seal improperly installed on the left- and right-hand partitions of the forward baggage compartment door. These
[[Page 18248]]
conditions, in the event of a fire in the baggage compartment, could result in smoke propagating into the main cabin.
Relevant Service Information
EMBRAER has issued Service Bulletin 145LEG-25-0060, dated November 18, 2005. The service bulletin describes procedures for doing a visual inspection for missing fire blocking material (an insulation blanket) on the partitions of the forward baggage compartment door, replacing the seal on both partitions with a new seal, and corrective action if necessary. The corrective action includes installing a new insulation blanket if fire blocking material is missing. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DAC mandated the service information and issued Brazilian airworthiness directive 2006-02-02, dated February 24, 2006, to ensure the continued airworthiness of these airplanes in Brazil.
FAA's Determination and Requirements of the Proposed AD
This airplane model is manufactured in Brazil and is type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DAC has kept the FAA informed of the situation described above. We have examined the DAC's findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States.
Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously.

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 have 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 that the proposed regulation:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
-
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. See the ADDRESSES section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39

Sec. 39.13 [Amended]
-
The Federal Aviation Administration (FAA) amends Sec. 39.13 by adding the following new airworthiness directive (AD):
Empresa Brasileira de Aeronautica S.A. (EMBRAER): Docket No. FAA- 2006-24366; Directorate Identifier 2006-NM-040-AD.

Unsafe Condition
(d) This AD results from a report indicating that certain airplanes were delivered with the fire blocking material missing and the seal improperly installed on the partitions of the forward baggage compartment door. We are issuing this AD to detect and correct such discrepancies on the partitions of the forward baggage compartment door, which, in the event of a fire in the baggage compartment, could result in smoke propagating into the main cabin.

compartment door, replace the seal on both partitions with a new seal, and accomplish all applicable corrective actions, by doing all the actions specified in the Accomplishment Instructions of EMBRAER Service Bulletin 145LEG-25-0060, dated November 18, 2005. All applicable corrective actions must be done before further flight.
Note 1: For the purposes of this AD, a general visual inspection 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.''
Alternative Methods of Compliance (AMOCs)
(g)(1) The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with Sec. 39.19 on any airplane to which the AMOC applies, notify the appropriate principal inspector in the FAA Flight Standards Certificate Holding District Office.
