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

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Proposed rule; withdrawal.

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

SUMMARY: The FAA withdraws a notice of proposed rulemaking (NPRM) that 
proposed a new airworthiness directive (AD) for certain EMBRAER Model 
ERJ 170 airplanes. The proposed AD would have required performing a 
one-time inspection for proper crimping of the terminal lugs for the 
power cables of each integrated drive generator (IDG), installing a new 
sleeve on the terminal, and re-crimping if necessary. Since the 
proposed AD was issued, we have received new data from the manufacturer 
that the proposed actions have been done on all affected airplanes. 
Accordingly, the proposed AD is withdrawn.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov, or in person at the Docket Management Facility office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the U.S. 
Department of Transportation, 400 Seventh Street, SW., Room PL-401, 
Washington, DC. This docket number is FAA-2006-24788; the directorate 
identifier for this docket is 2006-NM-073-AD.

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 ERJ 170 airplanes. That NPRM was published 
in the Federal Register on May 17, 2006 (71 FR 28628). The NPRM would 
have required performing a one-time inspection for proper crimping of 
the terminal lugs for the power cables of each integrated drive 
generator (IDG), installing a new sleeve on the terminal, and re-
crimping if necessary. The NPRM resulted from a report that the 
terminal lugs for the power cables of the IDGs may not be adequately 
crimped, which could allow the cables to be pulled out of the terminals 
with no significant force. The proposed actions were intended to 
prevent loss of all normal electrical power for the airplane, and 
consequent reduced controllability of the airplane.

Actions Since NPRM Was Issued

    Since we issued the NPRM, Empresa Brasileira de Aeronautica S.A. 
(EMBRAER), the airplane manufacturer, has informed us that the proposed 
actions have been done on all affected airplanes.

FAA's Conclusions

    Upon further consideration, we have determined that the proposed 
actions are no longer necessary because the proposed actions have 
already been accomplished on all airplanes listed in the applicability 
of the NPRM. Accordingly, the NPRM is withdrawn.
    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).

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Safety.

The Withdrawal

    Accordingly, we withdraw the NPRM, Docket No. FAA-2006-24788, 
Directorate Identifier 2006-NM-073-AD, which was published in the 
Federal Register on May 17, 2006 (71 FR 28628).

    Issued in Renton, Washington, on July 27, 2006.
