704A33651243 installed, certificated in any 

category. 

(b) Unsafe Condition 

This AD defines the unsafe condition as 

the seizure of the bearing. This condition 

could result in hydraulic pump drive belt 

failure, loss of hydraulic servo assistance, 

and subsequent loss of control of the 

helicopter. 

(c) Affected ADs 

This AD supersedes AD 2013–15–03, 

Amendment 39–17519 (78 FR 44422, July 24, 

2013). 

(d) Effective Date 

This AD becomes effective December 11, 

2017. 

(e) Compliance 

You are responsible for performing each 

action required by this AD within the 

specified compliance time unless it has 

already been accomplished prior to that time. 

(f) Required Actions 

(1) For each bearing with less than 115 

hours time-in-service (TIS), before 

accumulating 150 hours TIS, and for each 

bearing with 115 or more hours TIS, within 

50 hours TIS, and for all helicopters 

thereafter at intervals not to exceed 150 hours 

TIS: 

(i) Grease each bearing in accordance with 

the Accomplishment Instructions, paragraph 

3.B.2.b., of Airbus Helicopters Alert Service 

Bulletin No. AS350–63.00.24, Revision 0, 

dated October 21, 2014 (ASB). 

(ii) Perform a test ground run. Inspect all 

grease that comes out of the bearing during 

the ground run and all grease around the 

bearing for bronze particles. 

(iii) If there are any bronze particles in the 

grease, before further flight, replace the 

bearing with bearing P/N 704A33651269. 

This constitutes terminating action for the 

inspections in this AD. 

Note 1 to paragraph (f)(1)(iii) of this AD: 

Hydraulic pump drive assembly P/N 

350A35–0132–01 is fitted with bearing P/N 

704A33651269. 

(2) Within 600 hours TIS and thereafter at 

intervals not to exceed 600 hours TIS: 

(i) Visually inspect the bearing for bronze 

particles in the grease. If there are any bronze 

particles in the grease, before further flight, 

replace the bearing with bearing P/N 

704A33651269. This constitutes terminating 

action for the inspections in this AD. 

(ii) Manually rotate the bearing and inspect 

for a friction point, brinelling, and a noise 

from the bearing. If there is a hard point, any 

brinelling, or any noise from the bearing, 

before further flight, replace the bearing with 

bearing P/N 704A33651269. 

(3) Replacing bearing P/N 704A33651243 

with bearing P/N 704A33651269, or 

replacing hydraulic pump drive assembly 

P/N 350A35–0132–00 with hydraulic pump 

drive assembly P/N 350A35–0132–01, 

constitutes terminating action for the 

inspections required by this AD.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Saab AB, Saab 

Aeronautics Model SAAB 340B 

airplanes. The NPRM published in the 

Federal Register on August 15, 2017 (82 

FR 38621) (‘‘the NPRM’’). 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2017–0067, dated April 24, 

2017 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for certain Saab AB, 

Saab Aeronautics Model SAAB 340B 

airplanes. The MCAI states: 

A few natural stall events, specifically 

when operating in icing conditions, have 

been experienced on SAAB 340 series 

aeroplanes, without receiving a prior stall 

warning. 

This condition, if not corrected, could 

result in loss of control of the aeroplane. 

To address this potential unsafe condition, 

SAAB developed a modified stall warning 

system, incorporating improved stall warning 

logic, and issued various Service Bulletins 

(SB) providing instructions to replace the 

Stall Warning Computer (SWC) with a new 

SWC, and instructions to activate the new 

SWC. The new system includes stall warning 

curves optimized for operation in icing 

conditions, which are activated by selection 

of Engine Anti-Ice. 

Consequently, EASA issued AD 2014–0218 

[which corresponds to FAA AD 2016–22–15, 

Amendment 39–18704 (81 FR 76843, 

November 4, 2016)] to require installation 

and activation of the improved SWC. That 

[EASA] AD excluded certain SAAB 340B 

aeroplanes by s/n [serial number]. 

Since EASA AD 2014–0218 was issued, 

SAAB developed a technical solution 

applicable for some of those previously 

excluded aeroplanes, and issued SB 340–27– 

117 and SB 340–27–118, providing 

instructions to modify and activate the new 

SWC. 

For the reasons described above, this 

[EASA] AD requires installation and 

activation of the improved SWC. 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2017– 

0777. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

Saab AB, Saab Aeronautics has issued 

Service Bulletin 340–27–117, dated 

January 23, 2017. This service 

information describes procedures for 

modifying the stall warning system. 

Saab AB, Saab Aeronautics has also 

issued Service Bulletin 340–27–118, 

dated January 23, 2017. This service 

information describes procedures for 

installing new stall warning computers 

and activating the modified stall 

warning system. 

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 4 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Modification, installation, and activation ......... 78 work-hours × $85 per hour = $6,630 ........ $33,000 $39,630 $158,520 

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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to transport category 


Pmangrum on DSK3GDR082PROD with RULES
51342 Federal Register / Vol. 82, No. 213 / Monday, November 6, 2017 / Rules and Regulations 

airplanes to the Director of the System 

Oversight Division. 

Regulatory Findings 

We 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 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.
