The proposed AD would have required modifying the routing of wire harness W407 near the fire extinguishing tube in the area of each engine, and installing 15:27 Jun 27, 2006 Jkt 208001 Discussion We proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new AD for certain EMBRAER Model EMB–145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes. That NPRM was published in the Federal Register on February 2, 2006 (71 FR 5626). The NPRM would have required modifying the routing of wire harness W407 near the fire extinguishing tube in the area of each engine, and installing new supports for related wiring. The NPRM resulted from reports of chafing of wire harness W407 against the supports and nacelle structure in the engine area. The proposed actions were intended to prevent such chafing, which could result in an engine shutting down during flight. Actions Since NPRM Was Issued Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Proposed rule; withdrawal. AGENCY: VerDate Aug<31>2005 new supports for related wiring. Since the proposed AD was issued, we have received new data indicating that the identified unsafe condition does not exist. Accordingly, the proposed AD is withdrawn.

SUPPLEMENTARY INFORMATION: Since we issued the NPRM, the airplane manufacturer, EMBRAER, has provided additional information concerning the unsafe condition identified in the NPRM. EMBRAER Service Bulletin 145–71–0008, Change 01, dated July 24, 2001 (which was referenced as the appropriate source of service information for accomplishing the proposed actions), addressed chafing of wire harness W407 on the left- and right-hand engines. However, EMBRAER subsequently indicates that the objective of that service bulletin was PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 36723 not considered to be a means to avoid in-flight shutdown (IFSD) and, in fact, wire harness W407 is not engine control related. The harness is related to the engine lip anti-ice system, starter control valve, engine fire detection system, and engine bleed air extraction systems. None of these systems are possible contributors to an uncommanded IFSD. In addition, reported IFSD events in the EMB–145 fleet related to chafing of a different harness—the engine control harness— are associated with the engine manufacturer-provided harness, which is not the subject of EMBRAER Service Bulletin 145–71–0008. EMBRAER states that chafing (among other things) of the engine control system harness can cause internal failure of the full authority digital engine control (FADEC), which leads to a fuel shutoff valve closure command. However, in May 2001, EMBRAER introduced FADEC internal modifications for airplanes in production to prevent an inadvertent IFSD. Also, for FADECs manufactured before May 2001, Rolls-Royce, the engine manufacturer, developed an external adapter with the same design objectives as those of EMBRAER’s internal modifications. These adapters have already been sent to operators to install in their affected airplanes. EMBRAER adds that the engine inspection tasks from the airplane maintenance program have been revised and improved, as well as the engine harness inspection and installation tasks in the aircraft maintenance manual (AMM). FAA’s Conclusions Upon further consideration, we have determined that the unsafe condition identified in the NPRM does not exist. Accordingly, the NPRM is withdrawn. We have coordinated this action with the Departamento de Aviacao Civil ¸˜ (DAC), which is the airworthiness authority for Brazil. The DAC indicates it is considering cancelling its related airworthiness directive, 2005–10–05, which was effective November 17, 2005. Withdrawal of the NPRM does not preclude the FAA from issuing another related action or commit the FAA to any course of action in the future. Regulatory Impact Since this action only withdraws an NPRM, it is neither a proposed nor a final rule and therefore is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).

The Proposal The FAA is considering an amendment to 14 CFR part 71 to modify Class E airspace at Pierre, SD, by modifying Class E airspace for the Pierre Regional Airport. Controlled airspace extending upward from the surface of the earth is needed to contain aircraft executing instrument approach procedures. The area would be depicted on appropriate aeronautical charts. Class E airspace areas extending upward from 700 feet or more above the surface of the earth are published in paragraph 6005, and Class E airspace areas designated as surface areas are published in Paragraph 6002, of FAA Order 7400.9N dated September 1, 2005, and effective September 16, 2005, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designations listed in this document would be published subsequently in the Order. The FAA has determined that this proposed regulation only involves an establishment body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore this, proposed regulation—(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) does not warrant preparation of a Regulatory Evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this proposed rule will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

SUPPLEMENTARY INFORMATION:

Discussion

    We proposed to amend part 39 of the Federal Aviation Regulations 
(14 CFR part 39) with a notice of proposed rulemaking (NPRM) for a new 
AD for certain EMBRAER Model EMB-145, -145ER, -145MR, -145LR, -145XR, -
145MP, and -145EP airplanes. That NPRM was published in the Federal 
Register on February 2, 2006 (71 FR 5626). The NPRM would have required 
modifying the routing of wire harness W407 near the fire extinguishing 
tube in the area of each engine, and installing new supports for 
related wiring. The NPRM resulted from reports of chafing of wire 
harness W407 against the supports and nacelle structure in the engine 
area. The proposed actions were intended to prevent such chafing, which 
could result in an engine shutting down during flight.

Actions Since NPRM Was Issued

    Since we issued the NPRM, the airplane manufacturer, EMBRAER, has 
provided additional information concerning the unsafe condition 
identified in the NPRM. EMBRAER Service Bulletin 145-71-0008, Change 
01, dated July 24, 2001 (which was referenced as the appropriate source 
of service information for accomplishing the proposed actions), 
addressed chafing of wire harness W407 on the left- and right-hand 
engines. However, EMBRAER subsequently indicates that the objective of 
that service bulletin was not considered to be a means to avoid in-
flight shutdown (IFSD) and, in fact, wire harness W407 is not engine 
control related. The harness is related to the engine lip anti-ice 
system, starter control valve, engine fire detection system, and engine 
bleed air extraction systems. None of these systems are possible 
contributors to an uncommanded IFSD. In addition, reported IFSD events 
in the EMB-145 fleet related to chafing of a different harness--the 
engine control harness--are associated with the engine manufacturer-
provided harness, which is not the subject of EMBRAER Service Bulletin 
145-71-0008.
    EMBRAER states that chafing (among other things) of the engine 
control system harness can cause internal failure of the full authority 
digital engine control (FADEC), which leads to a fuel shutoff valve 
closure command. However, in May 2001, EMBRAER introduced FADEC 
internal modifications for airplanes in production to prevent an 
inadvertent IFSD. Also, for FADECs manufactured before May 2001, Rolls-
Royce, the engine manufacturer, developed an external adapter with the 
same design objectives as those of EMBRAER's internal modifications. 
These adapters have already been sent to operators to install in their 
affected airplanes. EMBRAER adds that the engine inspection tasks from 
the airplane maintenance program have been revised and improved, as 
well as the engine harness inspection and installation tasks in the 
aircraft maintenance manual (AMM).

FAA's Conclusions

    Upon further consideration, we have determined that the unsafe 
condition identified in the NPRM does not exist. Accordingly, the NPRM 
is withdrawn.
    We have coordinated this action with the Departamento de 
Avia[ccedil][atilde]o Civil (DAC), which is the airworthiness authority 
for Brazil. The DAC indicates it is considering cancelling its related 
airworthiness directive, 2005-10-05, which was effective November 17, 
2005.
    Withdrawal of the NPRM does not preclude the FAA from issuing 
another related action or commit the FAA to any course of action in the 
future.

Regulatory Impact

    Since this action only withdraws an NPRM, it is neither a proposed 
nor a final rule and therefore is not covered under Executive Order 
12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979).
