AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Agusta Model A109E, A109K2, A119, 

and AW119 MKII helicopters. This 

proposed AD was prompted by a report 

of a crack that was found on a Gleason 

crown. This proposed AD would require 

repetitively performing a magnetic 

particle inspection of the Gleason crown 

for a crack. We are proposing this AD 

to detect a crack, which could cause 

damage to or loss of the main rotor drive 

and subsequent loss of control of the 

helicopter. 

DATES: We must receive comments on 

this proposed AD by September 2, 2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Discussion 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD No. 2013– 

0118, dated June 3, 2013, to correct an 

unsafe condition for Agusta Model 

A109K2, A109E, A119, and AW119MKII 

helicopters. EASA advises that during 

an overhaul of an A119 main 

transmission, part number (P/N) 109– 

0400–05–103, a crack on the Gleason 

crown, P/N 109–0403–07–103, was 

found. EASA further states that an 

investigation by Agusta revealed that 

the crack originated from the bottom of 

one of the 40 threaded holes in the 

Gleason crown, and that this partnumbered Gleason crown is also 

installed on Model A109 helicopters. 

EASA states that this condition, if not 

corrected, could cause damage to or loss 

of the main rotor drive and loss of 

control of the helicopter. To correct this 

unsafe condition, EASA AD No. 2013– 

0118 requires repetitive magnetic 

particle inspections of the Gleason 

crown and, if there is a crack, replacing 

the Gleason crown with a different partnumbered Gleason crown. EASA AD 

No. 2013–0118 also prohibits installing 

a Gleason crown, P/N 109–0403–07– 

103, or a Gleason crown assembly, P/N 

109–0401–27–101 or P/N 109–0401–27– 

109, on any helicopter, as Gleason 

crown, P/N 109–0403–07–103, is a 

component of these assemblies. 

Relevant Service Information 

We reviewed Agusta Bollettino 

Tecnico (BT) No. 109EP–128 for Model 

A109E helicopters, Agusta BT No. 

109K–57 for Model A109K2 helicopters, 

and Agusta BT No. 119–058 for Model 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 79, No. 136 / Wednesday, July 16, 2014 / Proposed Rules 41463 

A119 and AW119MKII helicopters, each 

Revision A and dated May 28, 2013. 

Each BT describes procedures for 

performing a magnetic particle 

inspection on the Gleason crown, P/N 

109–0403–07–103, for a crack. If there is 

a crack, each BT specifies replacing the 

Gleason crown assembly with a Gleason 

crown assembly, P/N 109–0401–27–107. 

We also reviewed Agusta BT No. 

109EP–126 for Model A109E 

helicopters, Agusta BT No. 109K–56 for 

Model A109K2 helicopters, and Agusta 

BT No. 119–053 for Model A119 and 

AW119MKII helicopters, each dated 

December 20, 2012. These BTs contain 

procedures for upgrading the 

transmission system by replacing the 

Gleason crown assembly with a Gleason 

crown assembly, P/N 109–0401–27–107. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of these same 

type designs. 

Proposed AD Requirements 

This proposed AD would require, for 

helicopters with a main transmission, 

P/N 109–0400–03–109, with 2,400 or 

more hours time-in-service (TIS), 

performing a magnetic particle 

inspection of the Gleason crown, P/N 

109–0403–07–103, within 200 hours 

TIS, and thereafter at intervals not 

exceeding 1,600 hours TIS. If there is a 

crack, this proposed AD would require 

replacing the Gleason crown assembly 

with a different part-numbered 

assembly before further flight. The 

proposed AD would also prohibit 

installing on any helicopter a Gleason 

crown, P/N 109–0403–07–103, or a 

Gleason crown assembly, P/N 109– 

0401–27–101 or P/N 109–0401–27–109. 

Differences Between This Proposed AD 

and the EASA AD 

This proposed AD requires 

compliance within 200 hours TIS for 

main transmissions with 2,400 or more 

hours. The EASA AD requires different 

compliance times, depending on the 

number of flight hours the transmission 

has accumulated. 

Costs of Compliance 

We estimate that this proposed AD 

affects 218 helicopters of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD. At an 

average labor rate of $85 per hour, 

magnetic particle inspecting the Gleason 

crown would require about 24 workhours, for an estimated cost per 

helicopter of $2,040, and a total cost of 

$444,720 for the U.S. fleet, per 

inspection cycle. 

If required, replacing the Gleason 

crown assembly would require about 24 

work-hours, and required parts would 

cost $29,000, for a cost per helicopter of 

$31,040. 

According to the manufacturer, some 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage for affected individuals. As a 

result, we have included all costs in our 

cost estimate. 

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.
