SUPPLEMENTARY INFORMATION: 

Background 

On March 5, 2012, the FAA published 

a notice of proposed rulemaking 

(NPRM) entitled, ‘‘Rules of Practice for 

Federally-Assisted Airport Enforcement 

Proceedings (Retrospective Regulatory 

Review)’’ (77 FR 13027). 

In that NPRM, the FAA proposed to 

update, simplify, and streamline rules of 

practice and procedure for filing and 

adjudicating complaints against 

federally-assisted airports. The 

proposed requirements would improve 

efficiency by enabling parties to file 

submissions with the FAA 

electronically, and by incorporating 

modern business practices into how the 

FAA handles complaints. If adopted, the 

amendment would reflect changes in 

applicable laws and regulations, and 

apply lessons learned since the existing 

rules were implemented in 1996. 

Correction 

In FR Doc. 2012–4993, beginning on 

page 13027 in the Federal Register of 

March 5, 2012, make the following 

correction: 

On page 13027, in the second column 

and fourth line under the NPRM’s 

publication, correct ‘‘Notice No. 12–01’’ 

to read as ‘‘Notice No. 12–02’’. 

Issued in Washington, DC, on March 26, 

2012.

Airworthiness Directives; Eurocopter 

France Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Eurocopter France (EC) Model SA– 

365N, SA–365N1, SA–366G1, AS– 

365N2, AS 365 N3, EC 155B, and 

EC155B1 helicopters. This proposed AD 

was prompted by the discovery of a 

cracked main rotor mast nut. This 

condition, if not corrected, could lead to 

complete failure of the mast nut, 

resulting in failure of the rotor mast and 

loss of control of the helicopter. This 

proposed AD would require replacing 

the main rotor mast nut with an 

airworthy main rotor mast nut. We are 

proposing this AD to prevent failure of 

the main rotor mast and subsequent loss 

of control of the helicopter. 

DATES: We must receive comments on 

this proposed AD by June 4, 2012. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Docket: Go to 

http://www.regulations.gov. Follow the 

online instructions for sending your 

comments electronically.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued AD No.: 2006– 

0368R1, dated December 2, 2010, and 

corrected December 8, 2010 (AD 2006– 

0368R1), to correct an unsafe condition 

for the EC Model SA 365 N, SA 365 N1, 

AS 365 N2, AS 365 N3, SA 366 G1, EC 

155 B, and EC 155 B1 helicopters. EASA 

advises that a cracked (partially failed) 

main rotor mast nut was discovered 

during a complete overhaul of a main 

rotor mast. The start of the crack was 

related to circular scoring found in the 

nut threads. EASA states that this 

condition, if not corrected, ‘‘could lead 

to complete failure of the mast nut, 

possibly resulting in failure of the rotor 

mast and consequent loss of control of 

the helicopter.’’ To address this unsafe 

condition, EASA issued Emergency AD 

2006–0368–E, dated December 6, 2006 

(AD 2006–0368–E), to require repetitive 

inspections of the mast nut, and 

replacement of the nut if cracked. Since 

issuance of AD 2006–0368–E, EC has 

developed modification (MOD) 0762C42 

to improve the strength of the mast nut 

by changing its material. Replacing mast 

nut part number (P/N) 360A31–1020–20 

with mast nut P/N 365A31–2060–20 or 

365A31–2060–21 (as applicable to 

helicopter type) ‘‘constitutes an optional 

terminating action’’ for the repetitive 

inspection requirements. For this 

reason, EASA issued AD 2006–0368R1 

‘‘to inform which helicopters remain 

subject to inspections and replacement 

requirements’’ of the AD. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all known relevant 

information and determined that an 

unsafe condition exists and is likely to 

exist or develop on other products of 

these same type designs. 

Related Service Information 

We reviewed EC Alert Service 

Bulletin (ASB) No. 62.00.23, Revision 1, 

for Model SA–365N, SA–365N1, AS– 

365N2, and AS 365 N3 helicopters; EC 

ASB 62.12, Revision 1, for Model SA– 

366G1 helicopters; and EC ASB 62A014, 

Revision 1, for Model EC 155B and 

EC155B1 helicopters, all dated Oct 27, 

2010. The ASBs contain procedures for 

repetitively inspecting the mast nut for 

a crack or failure. The ASBs remove any 

helicopter with MOD 0762C42 

incorporated from the applicability of 

the ASB. EASA classified this ASB as 

mandatory and issued AD 2006–0368R1 

to ensure the continued airworthiness of 

these helicopters. 

Proposed AD Requirements 

This proposed AD would require, for 

EC Model SA–365N, SA–365N1, 

SA366G1, AS–365N2, AS 365 N3, EC 

155B, and EC155B1 helicopters, 

certificated in any category, with a mast 

nut P/N 360A31–1020–20 installed: 

• For EC Models SA–365N, SA– 

365N1, AS–365N2, and AS 365 N3, 

prior to accumulating 1,650 hours timein-service (TIS) or within the next 50 

hours TIS, whichever occurs later, 

remove mast nut P/N 360A31–1020–20 

and replace with an airworthy mast nut 

of a different P/N. 

• For EC Model SA–366G1, prior to 

accumulating 990 hours TIS or within 

the next 30 hours TIS, whichever occurs 

later, remove mast nut P/N 360A31– 

1020–20 and replace with an airworthy 

mast nut of a different P/N. 

• For EC Models EC 155B and 

EC155B1, prior to accumulating 660 

hours TIS or within the next 50 hours 

TIS, whichever occurs later, remove 

mast nut P/N 360A31–1020–20 and 

replace with an airworthy mast nut of a 

different P/N. 

Differences Between This Proposed AD 

and the EASA AD 

The EASA AD allows for either 

inspecting the mast nut at regular 

intervals or replacing the mast nut, 

while the proposed AD requires 

replacing the mast nut. The EASA AD 

uses flight hours of the main rotor mast 

assembly, while the proposed AD uses 

TIS of the helicopter. 

Costs of Compliance 

We estimate that this proposed AD 

affects 30 helicopters of U.S. registry. 

We estimate that replacing the mast nut 

with an airworthy mast nut would 

require 32 work-hours, at an average 

labor cost of $85 per work-hour. Parts 

would cost about $3,100. Based on these 

costs, we estimate a total cost per 

helicopter of $5,820, and a total cost for 

the U.S. operator fleet of $174,600. 

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.

Federal Register / Vol. 77, No. 65 / Wednesday, April 4, 2012 / Proposed Rules 20321 

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.
