Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD No. 2012– 

0262, dated December 14, 2012 (EASA 

AD 2012–0262), to correct an unsafe 

condition for the Agusta Model AB139 

and AW139 helicopters. EASA advises 

that incorrectly installed NLG pins, part 

number 1661–0001, were discovered on 

several aircraft. Incorrectly installed 

pins create a pre-stress condition on the 

pin flange. According to EASA, a 

subsequent technical investigation by 

Agusta concluded that the incorrect 

installation could be present on a 

number of other helicopters. EASA 

states that this condition could lead to 

NLG structural failure and consequent 

collapse during landing or taxi, 

resulting in damage to the helicopter 

and injury to the occupants. EASA AD 

2012–0262 requires inspecting the NLG 

pin installation on both the left and 

right arms to determine if the pin, 

washers, and nuts are correctly installed 

and, depending on findings, inspecting 

the bolts, nuts, and pins for corrosion, 

and also inspecting the pins for surface 

cracks, and correctly installing the pins. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of Italy and are 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Italy, EASA, its 

technical representative, has notified us 

of the unsafe condition described in its 

AD. We are proposing this AD because 

we evaluated all known relevant 

information and determined that an 

unsafe condition is likely to exist or 

develop on other products of the same 

type design.

Federal Register / Vol. 78, No. 134 / Friday, July 12, 2013 / Proposed Rules 41889 

Related Service Information 

Agusta has issued Bollettino Tecnico 

No. 139–306, dated December 12, 2012 

(BT 139–306), for Model AB139 and 

AW139 helicopters. BT 139–306 

describes procedures to inspect for 

correct installation of the bolts, nuts, 

washers, and pins, inspecting the bolt 

head and nut for corrosion, and 

inspecting the pins for surface cracks. 

Proposed AD Requirements 

This proposed AD would require, 

within 50 hours time in service (TIS), 

inspecting the pin installations in the 

left and right arms for correct 

installation of the pin, bolts, washers, 

and nuts. 

• If the installation is not correct, this 

proposed AD would require: 

Æ Inspecting the bolt and nut for 

corrosion. If there is any corrosion, 

removing the bolt and nut from service. 

Æ Inspecting the pin for corrosion, a 

crack, and damage. If there is any 

corrosion, removing the corrosion and 

measuring the pin diameter. If the pin 

diameter is less than 25.36 mm (.998 in) 

or if there is a crack in the pin, 

removing the pin from service. 

Æ Dye penetrant inspecting the pin 

flange for surface cracks. If there is a 

surface crack, removing the pin from 

service. 

• If the installation is correct, 

inspecting the bolt head and nut for 

corrosion would be required. If there is 

any corrosion, removing the bolt or nut 

from service would be required. 

Differences Between This Proposed AD 

and the EASA AD 

The EASA AD requires compliance 

within 50 flight hours or 1 month, while 

this proposed AD requires compliance 

within 50 hours TIS. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 102 helicopters of U.S. 

Registry. We estimate that operators 

may incur the following costs in order 

to comply with this AD. At an average 

labor rate of $85 per hour, inspecting 

the nose landing gear arm pins would 

require about 1 work hour, for a cost per 

helicopter of $85 and a total cost to U.S. 

operators of $8,670. If required, 

replacing a pin would require about 1 

work hour, and required parts cost 

$1,680, for a cost per helicopter of 

$1,765. The cost to replace a bolt or nut 

is minimal. 

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 proposed 

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, 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 to the extent that it justifies 

making a regulatory distinction; 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 an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

procedure. 

The Proposal 

This action proposes to amend Title 

14, Code of Federal Regulations (14 

CFR), Part 71 by amending Class E 

airspace extending upward from 1,200 

feet above the surface to accommodate 

new standard instrument approach 

procedures at Mandan Municipal 

Airport, Mandan, ND. Airspace would 

be added within a 30-mile radius of the 

final approach fix for the new RNAV 

(GPS) RWY 31 instrument approach 

procedure to provide adequate 

controlled airspace for the safety and 

management of IFR operations at the 

airport. Geographic coordinates would 

also be updated to coincide with the 

FAA’s aeronautical database. 

Class E airspace areas are published 

in Paragraph 6005 of FAA Order 

7400.9W, dated August 8, 2012 and 

effective September 15, 2012, which is 

incorporated by reference in 14 CFR 

71.1. The Class E airspace designation 

listed in this document would be 

published subsequently in the Order. 

The FAA has determined that this 

proposed regulation only involves an 

established body of technical 

regulations for which frequent and 

routine amendments are necessary to 

keep them operationally current. It, 

therefore, (1) Is not a ‘‘significant 

regulatory action’’ under Executive 

Order 12866; (2) is not a ‘‘significant
