RIN 2120-AA64

Airworthiness Directives; The Boeing Company Model 767-200, -300, 
-300F, and -400ER Series Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to certain Model 767-200, -300, -300F, and 
-400ER series airplanes. The existing AD currently requires an 
inspection to determine if certain motor operated valve actuators for 
the fuel tanks are installed, and related investigative and corrective 
actions if necessary. This proposed AD would add airplanes and, for 
certain airplanes, require additional inspections to determine if 
certain motor operated valve actuators for the fuel tanks are 
installed, and related investigative and corrective actions if 
necessary. This proposed AD results from fuel system reviews conducted 
by the manufacturer. We are proposing this AD to prevent an ignition 
source inside the fuel tanks, which, in combination with flammable fuel 
vapors, could result in a fuel tank explosion and consequent loss of 
the airplane.

DATES: We must receive comments on this proposed AD by April 28, 2011.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    On October 19, 2009, we issued AD 2009-22-13, amendment 39-16066 
(74 FR 55755, October 29, 2009), for certain Boeing Model 767-200, -
300, -300F, and -400ER series airplanes. That AD requires an inspection 
to determine if certain motor operated valve (MOV) actuators for the 
fuel tanks are installed, and related investigative and corrective 
actions if necessary. That AD resulted from fuel system reviews 
conducted by the manufacturer. We issued that AD to prevent an ignition 
source inside the fuel tanks, which, in combination with flammable fuel 
vapors, could result in a fuel tank explosion and consequent loss of 
the airplane.

Actions Since Existing AD Was Issued

    Since we issued AD 2009-22-13, Boeing issued a revision to Boeing 
Alert Service Bulletin 767-28A0090, dated July 3, 2008 (which was 
referenced as a source of service information in AD 2009-22-13). Boeing 
Service Bulletin 767-28A0090, Revision 2, dated September 2, 2010, 
corrects the group configuration assignment for certain airplanes, adds 
airplanes to the effectivity, and adds additional work for certain 
airplanes that accomplished Boeing Alert Service Bulletin 767-28A0090, 
dated July 3, 2008; or Boeing Service Bulletin 767-28A0090, Revision 1, 
dated April 1, 2010. The actions described in Boeing Service Bulletin 
767-28A0090, Revision 2, dated September 2, 2010, are similar to those 
described in Boeing Alert Service Bulletin 767-28A0090, dated July 3, 
2008.

[[Page 13535]]

    The airplanes that were assigned to the wrong group configuration 
(Group 3 instead of Group 2) and accomplished the requirements of AD 
2009-22-13 in accordance with Boeing Alert Service Bulletin 767-
28A0090, dated July 3, 2008, need to do additional inspections to 
determine if certain motor operated valve actuators for the fuel tanks 
are installed, and related investigative and corrective actions if 
necessary, in accordance with Boeing Service Bulletin 767-28A0090, 
Revision 2, dated September 2, 2010 (the new group configuration has 
more work packages than the old group configuration).
    The airplanes that were assigned to the wrong group configuration 
(Group 4 instead of Group 1) in Boeing Alert Service Bulletin 767-
28A0090, dated July 3, 2008; or Boeing Service Bulletin 767-28A0090, 
Revision 1, dated April 1, 2010; and accomplished actions using either 
of those service bulletins need to do additional inspections to 
determine if certain MOV actuators for the fuel tanks are installed, 
and related investigative and corrective actions if necessary, in 
accordance with Boeing Service Bulletin 767-28A0090, Revision 2, dated 
September 2, 2010 (the new group configuration has more work packages 
than the old group configuration).

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to develop on other airplanes of the 
same type design. For this reason, we are proposing this AD, which 
would supersede AD 2009-22-13 and would retain the requirements of the 
existing AD. This proposed AD would also require, for certain 
airplanes, accomplishing the actions specified in the Boeing Service 
Bulletin 767-28A0090, Revision 2, dated September 2, 2010, described 
previously.

Costs of Compliance

    There are about 398 airplanes of U.S. registry. The following table 
provides the estimated costs for U.S. operators to comply with this 
proposed AD.

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:
    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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by removing amendment 39-16066 (74 FR 
55755, October 29, 2009) and adding the following new AD:

The Boeing Company: Docket No. FAA-2011-0158; Directorate Identifier 
2010-NM-118-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by April 28, 
2011.

Affected ADs

    (b) This AD supersedes AD 2009-22-13, Amendment 39-16066.

Applicability

    (c) This AD applies to The Boeing Company Model 767-200, -300, -
300F, and -400ER series airplanes, certificated in any category; as

September 2, 2010.

Subject

    (d) Air Transport Association (ATA) of America Code 28: Fuel.

Unsafe Condition

    (e) This AD results from fuel system reviews conducted by the

explosion and consequent loss of the airplane.

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the
