The Commission also directed the
staff to gather information on the
options presented in SECY–10–0165,
dated December 27, 2010,4 concerning
the staff’s approach to a risk-informing
10 CFR Part 61. Previously, the NRC
staff sponsored an earlier workshop on
SECY–10–0165, on March 4, 2011 (76
FR 10810). The staff intends to seek the
public’s views on earlier stakeholder
comments received as well as other
proposals for a risk-informed revision of
10 CFR Part 61.

IV. Emerging Issues Concerning Part 61
The NRC staff has also conducted
other activities related to 10 CFR Part
61. These include revisions to the
Commission’s LLW Volume Reduction
Policy Statement (76 FR 50500; August
15, 2011); and the Concentration
Averaging Branch Technical Position
(76 FR 4739; January 26, 2011). Through
the course of those stakeholder
interactions, the staff received
comments and suggestions relevant to
the more comprehensive revision of 10
CFR Part 61. For example, stakeholders
have recommended changes that would
lengthen the period of institutional
controls and allow a site-specific
intruder assessment. Some stakeholders
have questioned basic fundamental
tenets of 10 CFR Part 61 including the
need to protect the inadvertent intruder.
The staff intends to seek the public’s
views on these and other stakeholder
comments.
V. NRC Public Meeting
The purpose of this public meeting is
to gather information from stakeholders
and other interested members of the
public concerning the rulemaking
proposals identified by the Commission
in its January 2012 SRM. This overall
approach is consistent with NRC’s
openness policy and is consistent with
the type of public outreach initiative
originally used by the NRC staff to
develop 10 CFR Part 61. The March 2,
2012, public meeting will be organized
into three parts. In the first part, the
NRC staff will seek public feedback on
the pros and cons of the four technical
issues specifically identified by the

Commission in its January 2012 SRM. In
the second part, the staff will identify
other technical issues identified by
stakeholders bearing on the 10 CFR Part
61 rule and seek public feedback on the
merits of these (additional) changes that
have been suggested in connection with
other on-going LLW regulatory
initiatives. In the third session, the staff
will seek public feedback on the options
proposed in SECY–10–0165 and accept
other proposals for a comprehensive
revision of 10 CFR Part 61.

Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to supersede an
existing airworthiness directive (AD)
that applies to certain The Boeing
Company Model 767 airplanes. The
existing AD currently requires revising
the Airworthiness Limitations Section
of the maintenance planning data (MPD)
document. Since we issued that AD, a
re-evaluation of certain doors and flaps
was done based on their fatigue-critical
nature. This proposed AD would revise
the maintenance program to incorporate
an additional limitation, and would add
airplanes to the applicability. We are
proposing this AD to detect and correct
fatigue cracking of the principal
structural element (PSEs), which could
adversely affect the structural integrity
of the airplane.
DATES: We must receive comments on
this proposed AD by April 9, 2012.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Discussion
On September 4, 2003, we issued AD
2003–18–10, amendment 39–13301 (68
FR 53503, September 11, 2003), for
certain The Boeing Company Model
767–200, –300, –300F, and –400ER
series airplanes. That AD requires
revising Subsection B, Section 9, of
Boeing 767 Maintenance Planning Data
(MPD) Document D622T001–9, titled
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ to incorporate Revision
October 2002; and Appendix B of
Boeing 767 MPD Document D622T001,
Revision December 2002. That AD
resulted from analysis of data that
identified specific initial inspection
thresholds and repetitive inspection
intervals for certain principal structural
elements (PSEs) to be added to the
airworthiness limitation instructions
(ALI). We issued that AD to ensure that
fatigue cracking of various PSEs is
detected and corrected; such fatigue
cracking could adversely affect the
structural integrity of these airplanes.
Actions Since Existing AD Was Issued
Since we issued AD 2003–18–10 (68
FR 53503, September 11, 2003), a reevaluation of certain doors and flaps
was done based on their fatigue-critical
nature. These items were classified as
PSEs and have been included in the
revised MPD Document.
D622T001–9, Revision July 2011, of the
Boeing 767 Maintenance Planning Data
(MPD) Document. This service
information describes procedures for an
additional critical fatigue inspection.
FAA’s Determination
We are proposing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD would retain
certain requirements of AD 2003–18–10
(68 FR 53503, September 11, 2003). This
proposed AD would revise the
Airworthiness Limitations Section of
the Maintenance Planning Data (MPD)
Document 767 Airworthiness
Limitations Instructions (ALI) which
adds a critical fatigue inspection and
revises the applicability to include
additional airplane line numbers.
Change to Existing AD
This proposed AD would retain
certain requirements of AD 2003–18–10
(68 FR 53503, September 11, 2003).
Since AD 2003–18–10 was issued, the
AD format has been revised, and certain
paragraphs have been rearranged. As a
result, the corresponding paragraph
identifiers have changed in this
proposed AD, as listed in the following
table:

Federal Register / Vol. 77, No. 35 / Wednesday, February 22, 2012 / Proposed Rules
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),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.

§ 39.13
[Amended]
2. The FAA amends § 39.13 by
removing airworthiness directive (AD)
2003–18–10, Amendment 39–13301 (68
FR 53503, September 11, 2003), and
adding the following new AD:
The Boeing Company: Docket No. FAA–
2012–0145; Directorate Identifier 2011–
NM–066–AD.
(a) Comments Due Date
The FAA must receive comments on this
AD action by April 9, 2012.
(b) Affected ADs
This AD supersedes AD 2003–18–10,
Amendment 39–13301 (68 FR 53503,
September 11, 2003).
(c) Applicability
This AD applies to The Boeing Company
Model 767–200, –300, –300F, and –400ER
series airplanes; certificated in any category;
line numbers 1 through 997 inclusive.
Note 1: This AD requires revisions to
certain operator maintenance documents to
include new inspections. Compliance with
these inspections is required by 14 CFR
91.403(c). For airplanes that have been
previously modified, altered, or repaired in
the areas addressed by these inspections, the
operator may not be able to accomplish the
inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c),
the operator must request approval for an
alternative method of compliance according
to paragraph (k) of this AD. The request
should include a description of changes to
the required inspections that will ensure the
continued damage tolerance of the affected
structure. The FAA has provided guidance
for this determination in Advisory Circular
(AC) 25.1529–1A.

(e) Unsafe Condition
This AD was prompted by a re-evaluation
of certain doors and flaps based on their
fatigue-critical nature. We are issuing this AD
to detect and correct fatigue cracking of the
principal structural elements (PSEs), which
could adversely affect the structural integrity
of the airplane.

Discussion
On September 19, 2002, we issued AD
2002–19–11, Amendment 39–12891 (67
FR 61478, October 1, 2002), for certain
Model 767–200 and –300 series
airplanes powered by Pratt & Whitney
JT9D series engines. The existing AD
requires replacement of the existing
deactivation pin, aft cascade pin
bushing, and pin insert on each thrust
reverser half, with new, improved
components. The existing AD resulted
from reports that the pin insert for the
deactivation pin was not able to
withstand the load of a powered
deployment and could fail on some
airplanes. We issued that AD to prevent
failure of the thrust reverser
deactivation pins, which could fail to

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to certain The Boeing Company Model 767 airplanes.
The existing AD currently requires revising the Airworthiness
Limitations Section of the maintenance planning data (MPD) document.
Since we issued that AD, a re-evaluation of certain doors and flaps was
done based on their fatigue-critical nature. This proposed AD would
revise the maintenance program to incorporate an additional limitation,
and would add airplanes to the applicability. We are proposing this AD
to detect and correct fatigue cracking of the principal structural
element (PSEs), which could adversely affect the structural integrity
of the airplane.
DATES: We must receive comments on this proposed AD by April 9, 2012.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
On September 4, 2003, we issued AD 2003-18-10, amendment 39-13301
(68 FR 53503, September 11, 2003), for certain The Boeing Company Model
767-200, -300, -300F, and -400ER series airplanes. That AD requires
revising Subsection B, Section 9, of Boeing 767 Maintenance Planning
Data (MPD) Document D622T001-9, titled ``Airworthiness Limitations
(AWLs) and Certification Maintenance Requirements (CMRs),'' to
incorporate Revision October 2002; and Appendix B of Boeing 767 MPD
Document D622T001, Revision December 2002. That AD resulted from
analysis of data that identified specific initial inspection thresholds
and repetitive inspection intervals for certain principal structural
elements (PSEs) to be added to the airworthiness limitation
instructions (ALI). We issued that AD to ensure that fatigue cracking
of various PSEs is detected and corrected; such fatigue cracking could
adversely affect the structural integrity of these airplanes.
Actions Since Existing AD Was Issued
Since we issued AD 2003-18-10 (68 FR 53503, September 11, 2003), a
re-evaluation of certain doors and flaps was done based on their
fatigue-critical nature. These items were classified as PSEs and have
been included in the revised MPD Document.
Relevant Service Information
We reviewed Subsection B, Airworthiness Limitations--Structural
Inspections, of Section 9, Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements (CMRs), D622T001-9, Revision
July 2011, of the Boeing 767 Maintenance Planning Data (MPD) Document.
This service information describes procedures for an additional
critical fatigue inspection.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would retain certain requirements of AD 2003-18-10
(68 FR 53503, September 11, 2003). This proposed AD would revise the
Airworthiness Limitations Section of the Maintenance Planning Data
(MPD) Document 767 Airworthiness Limitations Instructions (ALI) which
adds a critical fatigue inspection and revises the applicability to
include additional airplane line numbers.
Change to Existing AD
This proposed AD would retain certain requirements of AD 2003-18-10
(68 FR 53503, September 11, 2003). Since AD 2003-18-10 was issued, the
AD format has been revised, and certain paragraphs have been
rearranged. As a result, the corresponding paragraph identifiers have
changed in this proposed AD, as listed in the following table:

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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
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 airworthiness directive
(AD) 2003-18-10, Amendment 39-13301 (68 FR 53503, September 11, 2003),
and adding the following new AD:
The Boeing Company: Docket No. FAA-2012-0145; Directorate Identifier
2011-NM-066-AD.
(a) Comments Due Date
The FAA must receive comments on this AD action by April 9,
2012.
(b) Affected ADs
This AD supersedes AD 2003-18-10, Amendment 39-13301 (68 FR
53503, September 11, 2003).
(c) Applicability
This AD applies to The Boeing Company Model 767-200, -300, -
300F, and -400ER series airplanes; certificated in any category;
line numbers 1 through 997 inclusive.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (k) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued damage tolerance of the affected structure. The FAA
has provided guidance for this determination in Advisory Circular
(AC) 25.1529-1A.
(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code 51, Standard Practices/Structures; 52, Doors;
53, Fuselage structure; 54, Nacelle/Pylons; 55, Stabilizers; 56,
Windows; and 57, Wings.
(e) Unsafe Condition
This AD was prompted by a re-evaluation of certain doors and
flaps based on their fatigue-critical nature. We are issuing this AD
to detect and correct fatigue cracking of the principal structural
elements (PSEs), which could adversely affect the structural
integrity of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
Restatement of Requirements AD 2003-18-10, Amendment 39-13301 (68 FR
