AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for Agusta 

S.p.A. (Agusta) Model AB412 and 

AB412 EP, and Bell Helicopter Textron 

(Bell) Model 412, 412CF, and 412EP 

helicopters with certain DART 

Aerospace Ltd. (Dart) high gear aft 

crosstubes (crosstube) installed. This 

AD requires adding a life limit of 10,000 

landings to the crosstube and removing 

from service any crosstubes with more 

than 10,000 accumulated landings. This 

AD is prompted by five separate reports 

of crosstube failures. The actions in this 

AD are intended to prevent failure of the 

crosstube and subsequent collapse of 

the landing gear. 

DATES: This AD is effective September 

17, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

On February 25, 2013, at 78 FR 12646, 

the Federal Register published our 

notice of proposed rulemaking (NPRM), 

which proposed to amend 14 CFR part 

39 to include an AD that would apply 

to Agusta Model AB412 and AB412 EP, 

and Bell Model 412, 412CF, and 412EP 

helicopters with certain Dart crosstubes 

installed. The NPRM proposed to 

require establishing a component 

history card for each crosstube, P/N 

D412–664–203; revising the 

airworthiness limitations of the 

maintenance manual to establish a life 

limit of 10,000 landings for each 

crosstube; and removing from service 

any crosstube with more than 10,000 

landings. The proposed requirements 

were intended to prevent failure of the 

crosstube and subsequent collapse of 

the landing gear. 

The NPRM was prompted by AD No. 

CF–2012–14R1, dated May 9, 2012, 

issued by Transport Canada Civil 

Aviation (TCCA), which is the aviation 

authority for Canada. TCCA issued AD 

No. CF–2012–14R1 to correct an unsafe 

condition for the Dart high gear aft 

crosstube assembly, part number (P/N) 

D412–664–203, approved under TCCA 

Supplemental Type Certificate (STC) 

SH01–9, FAA STC No. SR01298NY, and 

European Aviation Safety Agency STC 

IM.R.S.01304, and installed on Agusta 

Model AB412 and AB412 EP and Bell 

Model 412, 412EP, and 412CF 

helicopters. TCCA advises that they 

have received five reports of these 

crosstubes failing. According to TCCA, 

based on these reports, the affected 

crosstube requires a life limitation of 

10,000 landings. As a result, TCCA 

issued AD No. CF–2012–14R1, which 


ehiers on DSK2VPTVN1PROD with RULES
49114 Federal Register / Vol. 78, No. 156 / Tuesday, August 13, 2013 / Rules and Regulations 

requires amending the instructions for 

continued airworthiness (ICA) to 

establish the new life limitation, and 

removing from service all crosstubes 

with more than 10,000 landings. 

Comments 

We gave the public the opportunity to 

participate in developing this AD, but 

we did not receive any comments on the 

NPRM (78 FR 12646, February 25, 

2013). 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of Canada and 

are approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Canada, TCCA, its 

technical representative, has notified us 

of the unsafe condition described in the 

TCCA AD. We are issuing this AD 

because we evaluated all information 

provided by TCCA and determined the 

unsafe condition exists and is likely to 

exist or develop on other helicopters of 

these same type designs and that air 

safety and the public interest require 

adopting the AD requirements as 

proposed. 

Related Service Information 

We reviewed Dart ICA No. ICA– 

D212–664, Revision 8, dated October 20, 

2011, which contains the airworthiness 

limitations, inspection requirements, 

proper placards and markings, and 

maintenance procedures for crosstube 

P/N D212–664 and D412–664. Revision 

8 establishes a life limit of 10,000 

landings for crosstube P/N D412–664– 

203. 

Costs of Compliance 

We estimate that this AD will affect 

76 helicopters of U.S. Registry. Based on 

an average labor cost of $85 per hour, 

we estimate that operators may incur 

the following costs in order to comply 

with this AD. Creating a component 

history card and amending the ICA 

requires about 1 work-hour, for a cost 

per helicopter of $85 and a total cost to 

U.S. operators of $6,460. Replacing a 

crosstube that has exceeded its life-limit 

requires about 6 work-hours and 

required parts will cost about $10,351, 

for a total cost per helicopter of $10,861. 

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 

helicopters identified in this rulemaking 

action. 

Regulatory Findings 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

(2) Is not a ‘‘significant rule’’ under 

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 AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION: AD 2012– 

11–02, Amendment 39–17065 (77 FR 

37790, June 25, 2012), applies to certain 

Eurocopter Model EC135 helicopters. 

AD 2012–11–02 currently requires, in 

part, visually checking the ring frame 

which connects the tail rotor Fenestron 

housing to the tailboom for a crack 

before further flight and thereafter at 

each preflight check, and allows this 

check to be performed by a pilot if 

certain regulatory recordkeeping 

requirements are met. As such, AD 

2012–11–02 currently includes the 

following as the last sentence under 

paragraph (f)(1): ‘‘The record must be 

maintained as required by 14 CFR 

91.173, 121.380, or 134.439.’’ 

As published, the reference to 14 CFR 

91.173 is incorrect. The correct 

reference is to 14 CFR 91.417. 

No other part of the preamble or
