Federal Aviation Administration (FAA), Department of Transportation (DOT).
Notice of proposed rulemaking (NPRM).
The FAA proposes to adopt a new airworthiness directive (AD) for certain EMBRAER airplanes as described previously. This proposed AD would require inspecting to determine the part number of the left- and right-hand windshield temperature controllers. For airplanes equipped with certain windshield temperature controllers, this proposed AD would also require replacing the attaching hardware of the power cable terminals of the windshield temperature controllers with new, improved attaching hardware; inspecting the power cable terminals for signs of melting or damage to the terminals, cable insulation, or plastic crimping ring; and performing corrective actions if necessary. This proposed AD results from reports of smoke on the flight deck caused by damage from poor electrical contact due to loosening of the attaching hardware of the power cables of certain windshield temperature controllers. We are proposing this AD to prevent overheating of the power cable terminals of the windshield temperature controllers, which could result in smoke and fire on the flight deck.
We must receive comments on this proposed AD by October 26, 2006.

The Agência Nacional de Aviaçao Civil (ANAC), which is the airworthiness authority for Brazil, notified us that an unsafe condition may exist on certain EMBRAER Model EMB-135BJ, -135ER, -135KE, -135KL, and -135LR airplanes and Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The ANAC has received reports of smoke on the flight deck caused by damage from poor electrical contact due to loosening of the attaching hardware of the power cable terminals of certain windshield temperature controllers. This condition, if not corrected, could lead to overheating of the power cable terminals of the windshield temperature controllers, which could result in smoke and fire on the flight deck.
Relevant Service Information
EMBRAER has issued Service Bulletin 145-30-0043, Revision 02, dated May 25, 2006; and Service Bulletin 145LEG-30-0013, dated June 28, 2005. The service information describes procedures for replacing the attaching hardware of the power cable terminals of certain windshield temperature controllers, part number (P/N) 3801D2( ), with new, improved attaching hardware; inspecting the power cable terminals for signs of melting or damage to the terminals, cable insulation, or plastic crimping ring; and performing corrective actions if necessary. Corrective actions include replacing any melted or damaged crimping ring, cable terminal, or cable. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition.
The ANAC mandated the service information and issued Brazilian airworthiness directive 2006-05-01, effective May 23, 2006, to ensure the continued airworthiness of these airplanes in Brazil.
FAA's Determination and Requirements of the Proposed AD
These airplane models are manufactured in Brazil and are type certificated for operation in the United States under the provisions of § 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the ANAC has kept the FAA informed of the situation described above. We have examined the ANAC'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.
Clarification of Inspection Terminology
The service bulletins specify to inspect for evidence of damage or melting. However, to eliminate any confusion about the proper type of inspection, we would require a “detailed inspection,” which is consistent with the type of inspection specified in Brazilian airworthiness directive 2006-05-01.
Clarification of Part Number (P/N) References
The service bulletins specify that certain windshield temperature controllers, having P/N 3801D2( ), are affected. The parentheses indicate that the P/N might or might not contain a suffix letter. Although the service bulletins identified in the following table make it clear that the INU part numbers, as identified in Table 1 of the AD, are the primary identifiers of all affected INUs, we have determined that these various suffix references could cause confusion. Therefore, to address all references to suffix letters in the service bulletins, we have revised the AD to read “-850( )/-851( )” where applicable.
Costs of Compliance
This proposed AD would affect about 689 airplanes of U.S. registry. The proposed actions would take about 1 work hour per airplane, at an average labor rate of $80 per work hour. Required parts would be supplied from operator stock. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $55,120, or $80 per airplane.
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 Start Printed Page 56058safety 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.
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:
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. See the ADDRESSES section for a location to examine the regulatory evaluation.Start List of Subjects
