Federal Register / Vol. 79, No. 41 / Monday, March 3, 2014 / Rules and Regulations 11697 

(d) Subject 

Air Transport Association of America 

(ATA) Code 24: Electric Power. 

(e) Reason 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 

originated by an aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as failure of 

the alternator indication system to indicate 

warning when one alternator is inoperative. 

We are issuing this AD to prevent the 

undetected loss of one engine alternator, 

which could result in reduced capability of 

the electrical generating power system.

Unless already done, do the following 

actions as specified in paragraphs (f)(1) 

through (f)(3) of this AD, including all 

subparagraphs:

Airworthiness Directives; Agusta 

S.p.A. Helicopters 

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 AB139 and 

AW139 helicopters with a certain wire 

strike protection system (WSPS) top 

cable cutter assembly installed. This AD 

requires reworking or replacing the top 

cable cutter assembly to increase 

clearance between the WSPS and the 

main rotor (M/R) blades and requires 

that the reworked or replaced part be 

marked at the end of the part number to 

reflect the field modification. This AD 

was prompted by a report of in-flight 

contact between the top cable-cutter 

assembly and two M/R blades. The 

actions of this AD are intended to 

prevent damage to the M/R blades and 

subsequent loss of helicopter control. 

DATES: This AD is effective April 7, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain document listed in this AD 

as of April 7, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion 

On August 29, 2012, at 77 FR 52270, 

the Federal Register published our 

notice of proposed rulemaking (NPRM), 

which proposed to amend 14 CFR part 

39 by adding an AD that would apply 

to Agusta Model AB139 and AW139 

helicopters with a WSPS top cable 

cutter assembly, part number (P/N) 423– 

83001–1, installed, which is part of the 

WSPS, P/N 4G9540F00211 or P/N 

4G9540F00311. The NPRM proposed to 

require reworking or replacing the top 

cable cutter assembly to increase 

clearance between the WSPS and the M/ 

R blades. The proposed requirements 

were intended to prevent damage to the 

M/R blades and subsequent loss of 

helicopter control. 

On July 3, 2013, at 78 FR 40055, the 

Federal Register published our 

supplemental notice of proposed 

rulemaking (SNPRM), which proposed 

to revise some of the actions in the 

NPRM. The SNPRM proposed to require 

the same actions as the NPRM, but also 

proposed to require identifying the 

reworked or replaced top cable cutter 

assembly in a visible and permanent 

way by adding ‘‘BT 139–126 Rev./’’ or 

‘‘FAA’’ at the end of the P/N. 

The NPRM and the SNPRM were 

prompted by AD No. 2008–0148, dated 

August 5, 2008, issued by EASA, which 

is the Technical Agent for the Member 

States of the European Union. The 

EASA AD advises of an incident of inflight contact between the top cable 

cutter assembly and two M/R blades. 

This condition, if not corrected, could 

cause damage to the rotor blades and 

lead to loss of control of the helicopter, 

EASA advises. EASA further notes that 

this unsafe condition is likely to occur 

in other helicopters of the same type 

design, so the EASA AD requires that 

top cable cutter assembly, P/N 423– 

830001–1, be reworked or replaced with 

a new unit, P/N 3G9506P01431. 

Comments 

We gave the public the opportunity to 

participate in developing this AD, but 

we received no comments on the 

SNPRM (78 FR 40055, July 3, 2013) or 

NPRM (77 FR 52270, August 29, 2012). 

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 the 

EASA AD. We are issuing this AD 

because we evaluated all information 

provided by EASA 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 Agusta Bollettino 

Tecnico No. 139–126, dated June 20, 

2008 (BT), which applies to Model 

AB139 and AW139 helicopters with 

certain serial-numbered WSPSs. The BT 

specifies, within 200 flight hours, 

reworking the top cable cutter assembly 

and marking it with ‘‘BT 139–126 Rev./ 

’’ in a visible and permanent manner. 

EASA classified this BT as mandatory 

and issued AD No. 2008–0148 to ensure 

the continued airworthiness of these 

helicopters. 

Costs of Compliance 

We estimate that this AD affects about 

39 helicopters of U.S. registry. We also 

estimate that it takes about 3 work-hours 

per helicopter to rework the top cable 

cutter assembly and to add ‘‘BT 139–126 

Rev./’’ or ‘‘FAA’’ at the end of the part 

number, 1 work-hour to replace the top 

cable cutter assembly, and 1 work-hour 

to remove the WSPS upper installation. 

The average labor rate is $85 per workhour. Required parts cost about $9,000 

per helicopter to replace the cutter. 

Based on these figures, we estimate the 

cost of this AD on U.S. operators to be 

$255 per helicopter to rework the top 

cable cutter assembly, $9,085 per 

helicopter to replace the top cable cutter 

assembly, and $85 per helicopter to 

remove the WSPS. 

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.
