RIN 2120-AA64


Airworthiness Directives; The Boeing Company 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 The Boeing 
Company Model 767 airplanes equipped with General Electric Model CF6-
80C2 engines. The NPRM proposed to require modifying a relay 
installation and associated wiring of the engine cowl anti-ice system 
and performing a functional test of the thrust reverser system. The 
NPRM also proposed to require replacing the operational program 
software of certain indicating/recording systems. Since we issued the 
NPRM, we have received new data that indicate the unsafe condition 
would not be adequately addressed by the proposed action. The 
manufacturer has issued new service information to address the unsafe 
condition. Consequently, we issued new rulemaking action that 
positively addresses the unsafe condition identified in the NPRM, and 
eliminates the need for the actions proposed in the NPRM. Accordingly, 
the NPRM is withdrawn.

DATES: As of October 23, 2013, the proposed rule, which was published 
in the Federal Register on May 18, 2005 (70 FR 28489), is withdrawn.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD action, the regulatory 
evaluation, any comments received, and other information. The street

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 Model 767 series airplanes. The NPRM published in the 
Federal Register on May 18, 2005 (70 FR 28489). The NPRM proposed to 
require modifying a relay installation and associated wiring of the 
engine cowl anti-ice system and performing a functional test of the 
thrust reverser system. The NPRM also proposed to require replacing the 
operational program software of certain indicating/recording systems. 
The NPRM was prompted by numerous operator reports of failures of the 
lock flexshaft of the thrust reverser actuation system (TRAS) between 
the upper actuator and the TRAS lock. We had proposed the AD to prevent 
high power in-flight deployment of a thrust reverser, which could cause 
high roll force and consequent departure from controlled flight.

Actions Since NPRM (70 FR 28489, May 18, 2005) Was Issued

    Since we issued the NPRM (70 FR 28489, May 18, 2005), we have 
received new data that indicate the unsafe condition would not be 
adequately addressed by the proposed action. Consequently, we issued a 
new NPRM (78 FR 3363, January 16, 2013) that positively addresses the 
unsafe condition identified in the NPRM (70 FR 28489, May 18, 2005) and 
eliminates the need for the actions proposed in that NPRM (70 FR 28489, 
May 18, 2005).

FAA's Conclusions

    We have determined that the unsafe condition identified in the NPRM 
(70 FR 28489, May 18, 2005) still exists. However, the unsafe condition 
is addressed in the new NPRM (78 FR 3363, January 16, 2013). 
Accordingly, the NPRM (70 FR 28489, May 18, 2005) is withdrawn.
    Withdrawal of the NPRM (70 FR 28489, May 18, 2005) does not 
preclude the FAA from issuing the related actions or commit the FAA to 
any course of action in the future.

Regulatory Impact

    Since this action only withdraws the NPRM (70 FR 28489, May 18, 
2005), 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

reference, Safety.

The Withdrawal

    Accordingly, we withdraw the NPRM, Docket No. FAA-2005-21236, 
Directorate Identifier 2005-NM-011-AD, which published in the Federal 
Register on May 18, 2005 (70 FR 28489).

    Issued in Renton, Washington, on September 30, 2013.
