amended technical basis document and 

commence with the rulemaking. 

Changes will also need to be made to 

any 10 CFR Part 61 performance 

assessment companion guidance 

document to address the recent June 

2012 direction. The completion date for 

submittal of a revised rulemaking 

package is currently July 19, 2013. 

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. 

The public meeting will be held on 

March 2, 2012, from 8 a.m. to 4 p.m. at 

the Marriott Renaissance Phoenix 

Downtown Hotel, 50 East Adams Street, 

Phoenix, Arizona 85004. Pre-registration 

for this meeting is not necessary. 

Members of the public choosing to 

participate in this meeting remotely can 

do so in one of two ways—online, or via

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 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. 

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:

Federal Register / Vol. 77, No. 35 / Wednesday, February 22, 2012 / Proposed Rules 10405 

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. 

§ 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. 

(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.

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 767–200 and –300 

series airplanes. 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. Since we issued that AD, 

we received reports that certain 

airplanes require installation of a new 

bushing and deactivation pin with 

increased load carrying capability and 

all airplanes powered by Pratt & 

Whitney JT9D series engines require 

installation of a new bracket for stowing 

the deactivation pin. This proposed AD 

would add a dye penetrant inspection 

for cracking of the rivet holes of the 

bushing plate and repair or replacement, 

if necessary. For certain airplanes, this 

proposed AD would require replacing 

the existing bushing with a new bushing 

and deactivation pin; and installing a 

new or serviceable stowage bracket for 

the deactivation pins on all airplanes 

powered by Pratt & Whitney JT9D series 

engines. We are proposing this AD to 

prevent failure of the thrust reverser 

deactivation pins, which could fail to 

prevent a deployment of a deactivated 

thrust reverser in flight and consequent 

reduced controllability of the airplane. 

DATES: We must receive comments on 

this proposed AD by April 9, 2012. 

ADDRESSES: You may send comments,

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
