Revisions to Fitness for Duty 

Programs’ Drug Testing Requirements 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Regulatory basis. 

SUMMARY: The U.S. Nuclear Regulatory 

Commission (NRC) is making available 

the regulatory basis for the ongoing 

proposed rulemaking effort to amend its 

regulations regarding drug testing 

requirements in NRC licensees’ fitness 

for duty programs. The regulatory basis 

documents the reasoning upon which 

the NRC determined rulemaking was the 

appropriate course of action. In this 

regulatory basis, the NRC recommends 

developing a proposed rule that would 

enhance the ability of NRC licensees to 

detect and deter drug use and the 

alignment of the NRC’s regulations with 

select drug testing provisions in the U.S. 

Department of Health and Human 

Services’ ‘‘Mandatory Guidelines for 

Federal Workplace Drug Testing 

Programs’’ issued in 2008. 

DATES: At this time, the NRC is not 

soliciting formal public comments on

Airworthiness Directives; Airbus 

Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Airbus Model A318, A319, A320, and 

A321 series airplanes. This proposed 

AD was prompted by a determination 

that certain special washers used in the 

retraction jack anchorage fitting bearing 

installation in the main landing gear 

(MLG) were incorrectly manufactured. 

This proposed AD would require an 

inspection of the left-hand (LH) and 

right-hand (RH) MLG retraction jack 

anchorage fitting bearing assemblies to 

verify that the special washer is seated 

correctly, and related investigative and 

corrective actions if necessary. We are 

proposing this AD to detect and correct 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 126 / Monday, July 1, 2013 / Proposed Rules 39191 

installation of incorrectly manufactured 

special washers, which could lead to a 

local stress concentration resulting in 

possible reduction of the fatigue life of 

the jack fitting, and consequent 

reduction of the structural integrity of 

the affected MLG. 

DATES: We must receive comments on 

this proposed AD by August 15, 2013. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0223, 

dated October 23, 2012 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for the specified products. The MCAI 

states: 

Airbus identified a batch of special 

washers, Part Number (P/N) 

D5725260120000 and P/N D5725664320000, 

which were incorrectly manufactured and 

delivered as spares from the supplier 

between October 2006 and January 2010. As 

a result of these manufacturing defects, the 

affected washers differ geometrically from 

the design specifications. The results of 

further analyses on Airbus A318, A319, A320 

and A321 aeroplanes demonstrate that the 

affected washers could be seated incorrectly 

when installed on aeroplanes, which could 

affect the main landing gear (MLG) retraction 

jack anchorage fitting bearing installation. 

This condition, if not detected and 

corrected, could lead to a local stress 

concentration which may reduce the fatigue 

life of the jack fitting, possibly reducing the 

structural integrity of the affected MLG. 

For the reasons described above, this 

[EASA] AD requires a one-time detailed 

visual inspection of the left-hand (LH) and 

right-hand (RH) MLG retraction jack 

anchorage fitting bearing assemblies to verify 

that the special washer is seated correctly 

and, depending on findings, the 

accomplishment of applicable [related 

investigative action and] corrective actions. 

The related investigative action is a 

detailed inspection of the jack 

anchorage fitting for damage, corrosion, 

cracks or other defects. Corrective 

actions include replacing the special 

washer with a new special washer and 

repairing the jack anchorage fitting if 

there are signs of damage, corrosion, or 

other defects. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Airbus has issued Airbus Service 

Bulletin A320–57–1169, Revision 01, 

dated September 18, 2012, and the 

following tasks in Subject 57–26–13, 

Attachment—Main Landing Gear, of 

Chapter 57, Wings, of the Airbus A318/ 

A319/A320/A321 Aircraft Maintenance 

Manual (AMM), Revision 50, dated 

November 1, 2012. 

• Task 57–26–13–400–001–A, 

Installation of the Bearing Assembly of 

the Forward Pintle Pin. 

• Task 57–26–13–400–002–A, 

Installation of the Bearing Assembly of 

the MLG Actuator Attachment. 

• Task 57–26–13–400–004–A, 

Installation of the Bearing Seals of the 

MLG Actuator Bearing Assembly. 

The actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

Airbus Service Bulletin A320–57– 

1169, Revision 01, dated September 18, 

2012, specifies to contact the 

manufacturer for instructions on how to 

repair certain conditions, but this 

proposed AD would require repairing 

those conditions using a method 

approved by either the Manager, 

International Branch, ANM–116, 

Transport Airplane Directorate, FAA; or 

the EASA (or its delegated agent). 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 851 products of U.S. 

registry. We also estimate that it would 

take about 3 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Based on 

these figures, we estimate the cost of the 

proposed AD on U.S. operators to be 


tkelley on DSK3SPTVN1PROD with PROPOSALS
39192 Federal Register / Vol. 78, No. 126 / Monday, July 1, 2013 / Proposed Rules 

$217,005, or $255 per product. In 

addition, we estimate that any necessary 

follow-on actions would take about 15 

work-hours, for a cost of $1,275 per 

product. We have received no definitive 

data that would enable us to provide 

part cost estimates for the on-condition 

actions specified in this proposed AD. 

We have no way of determining the 

number of products that may need these 

actions. 

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 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 this 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

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 all The Boeing Company 

Model 737–100, –200, –200C, –300, 

–400, and –500 series airplanes. The 

existing AD currently requires repetitive 

inspections for discrepancies of each 

carriage spindle of the outboard midflaps; repetitive gap checks of the 

inboard and outboard carriages of the 

outboard mid-flaps to detect fractured 

carriage spindles; measuring to ensure 

that any new or serviceable carriage 

spindle meets minimum allowable 

diameter measurements taken at three 

locations; repetitive inspections, 

measurements, and overhaul of the 

carriage spindles; replacement of any 

carriage spindle when it has reached its 

maximum life limit; and corrective 

actions if necessary. Since we issued 

that AD, we received a report of failure 

of both flap carriages. This proposed AD 

would require reducing the life limit of 

the carriages, reducing the repetitive 

interval for certain inspections and gap 

checks for certain carriages. This 

proposed AD would also add an option, 

for certain replacements, of doing an 

inspection, and related investigative and 

corrective actions if necessary. We are 

proposing this AD to detect and correct 

cracked, corroded, or fractured carriage 

spindles, which could lead to severe 

flap asymmetry, and could result in 

reduced control or loss of controllability 

of the airplane. 

DATES: We must receive comments on 

this proposed AD by August 15, 2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
