ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2013–15– 

03 for Eurocopter France Model 

AS350B, AS350BA, AS350B1, 

AS350B2, AS350B3, AS350C, AS350D, 

and AS350D1 helicopters. AD 2013–15– 

03 required inspecting the hydraulic 

pump drive pulley bearing (bearing) for 

leaks, rust, overheating, and condition. 

This new AD adds a requirement to 

grease the bearing and inspect for 

bronze particles in the grease, and 

changes the inspection and inspection 

intervals of the bearing until it is 

replaced with an improved bearing. 

This AD was prompted by additional 

reports of hydraulic pump drive belt 

failure caused by bearing seizures. The 

actions of this AD are intended to 

prevent an unsafe condition on these 

products.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to remove AD 2013–15–03, 

Amendment 39–17519 (78 FR 44422, 

July 24, 2013) and add a new AD. AD 

2013–15–03 applied to Eurocopter 

France (now Airbus Helicopters) Model 

AS350B, AS350BA, AS350B1, 

AS350B2, AS350B3, AS350C, AS350D, 

and AS350D1 helicopters with a single 

hydraulic system and a hydraulic pump 

drive installed. AD 2013–15–03 

required repetitively inspecting the 

bearing for leaks, rust, overheating, and 

condition. AD 2013–15–03 was 

prompted by six reports of hydraulic 

pump drive belt failure caused by 

bearing seizures. AD 2013–15–03 also 

was prompted by AD No. 2013–0044–E, 

dated February 27, 2013, issued by 

EASA, which is the Technical Agent for 

the Member States of the European 

Union. EASA advised that hydraulic 

pump drive belt failures caused by 

seizure of the bearing, for helicopters 

with a single hydraulic system, could 

lead to loss of hydraulic servo assistance 

and an increase in pilot workload to the 

point that the helicopter needs to land 

as soon as possible. 

The NPRM published in the Federal 

Register on April 29, 2016 (81 FR 

25622). The NPRM was prompted by 

EASA AD No. 2013–0284–E, dated 

December 2, 2013, which supersedes 


Pmangrum on DSK3GDR082PROD with RULES
Federal Register / Vol. 82, No. 213 / Monday, November 6, 2017 / Rules and Regulations 51339 

EASA AD No. 2013–0044–E. EASA AD 

No. 2013–0284–E advises that the 

hydraulic pump drive failure was 

caused by accidental indentation of the 

raceways from incorrect fitting of the 

bearing. Airbus Helicopters then 

introduced a new bearing, part number 

(P/N) 704A33651269, to replace bearing 

P/N 704A33651243. This replacement 

corrects the unsafe condition as it has a 

reduced pre-loading value, which 

significantly improves its reliability. 

EASA revised AD No. 2013–0284–E 

with AD No. 2013–0284R1, dated July 

25, 2014, to exclude helicopters that had 

replaced the bearing with bearing P/N 

704A33651269. EASA then superseded 

AD No. 2013–0284R1 with EASA AD 

No. 2014–0233, dated October 23, 2014, 

to retain the inspections and require 

replacement of bearing P/N 

704A33651243 with bearing P/N 

704A33651269. Installation of the new 

bearing constitutes terminating action 

for the repetitive inspections. 

As a result, the NPRM proposed to 

retain the inspection requirements in 

AD 2013–15–03, add a requirement to 

grease the bearing and inspect for 

bronze particles in the grease, and 

change the inspection and inspection 

intervals of the bearing until it is 

replaced with the improved bearing. 

Since the NPRM was issued, the 

FAA’s Aircraft Certification Service has 

changed its organizational structure. 

The new structure replaces product 

directorates with functional divisions. 

We have revised some of the office titles 

and nomenclature throughout this Final 

rule to reflect the new organizational 

changes. Additional information about 

the new structure can be found in the 

Notice published on July 25, 2017 (82 

FR 34564). 

Comments 

After our NPRM was published, we 

received a comment from Airbus 

Helicopters. 

Request 

Airbus Helicopters requested that we 

revise the Applicability section of the 

AD to eliminate confusion. Specifically, 

Airbus Helicopters requested we change 

the AD to apply to helicopters with 

‘‘Single Hydraulics pre mod 079568 

with Hydraulic pump drive assembly 

part number 350A35–0132–00 with 

bearing part number 704A33651243 

installed.’’ 

We do not agree. Airbus Helicopters’ 

request does not make the Applicability 

section clearer because the unsafe 

condition lies with the bearing, which is 

also installed in hydraulic pump drive 

assembly part number 350A35–0132–00 

V. Leaving the original Applicability 

language makes this point clear. 

FAA’s Determination 

We have reviewed the relevant 

information and determined that an 

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. 

Differences Between This AD and the 

EASA AD 

The EASA AD applies to Airbus 

Helicopters Model AS350BB 

helicopters, and this AD does not 

because the Model AS350BB has no 

FAA-issued type certificate. This AD 

applies to Model AS350D1 and AS350C 

helicopters, while the EASA AD does 

not. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Airbus Helicopters ASB 

No. AS350–63.00.24, Revision 0, dated 

October 21, 2014 (ASB), for Model 

AS350B, AS350BA, AS350BB, 

AS350B1, AS350B2, AS350B3, AS350D, 

and military Model AS350L1 

helicopters with a single hydraulic 

system and a hydraulic pump drive 

assembly P/N 350A35–0132–00. The 

ASB calls for mandatory replacement of 

bearing P/N 704A33651243 with bearing 

P/N 704A33651269 and introduces a 

preventative maintenance operation for 

bearing P/N 704A33651243 until it is 

replaced. 

This service information is reasonably 

available because the interested parties 

have access to it through their normal 

course of business or by the means 

identified in the ADDRESSES section. 

Costs of Compliance 

We estimate that this AD affects 729 

helicopters of U.S. Registry and that 

labor costs average $85 per work hour. 

Based on these estimates, we expect the 

following costs: 

• Greasing and visually inspecting 

the bearing requires 1.5 work hours and 

no parts are needed. We estimate a total 

cost of $128 per helicopter and $93,312 

for the U.S. fleet per inspection cycle. 

• Inspecting and manually rotating 

the bearing requires 2 work hours, and 

no parts are needed. We estimate a total 

cost of $170 per helicopter and $123,930 

for the U.S. fleet per inspection cycle. 

• Replacing the bearing requires 2 

work hours and $1,571 for parts, for a 

total cost of $1,741 per helicopter and 

$1,269,189 for the U.S. fleet. 

• Replacing the hydraulic pump drive 

assembly requires 2 work hours and 

$8,543 for parts, for a total cost of 

$8,713 per helicopter and $6,351,777 for 

the U.S. fleet. 

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 have determined that 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 a regulatory 

distinction is required, 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.
