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 Airbus Model A300 B4– 

600, B4–600R, and F4–600R series 

airplanes, Model A300 C4–605R Variant 

F airplanes (collectively called Model 

A300–600 series airplanes), and Model 

A310 series airplanes. The NPRM 

published in the Federal Register on 

June 9, 2017 (82 FR 26758) (‘‘the 

NPRM’’). The NPRM was prompted by 

reports of unreliable airspeed 

indications that were caused by pitot 

heater resistance shorted to ground. The 

NPRM proposed to require replacement 

of certain parts. We are issuing this AD 

to ensure proper flight crew awareness 

of unreliable airspeed indications. This 

condition, if not recognized by the flight 

crew, could possibly result in reduced 

control of the airplane. 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2016–0195, 

dated September 30, 2016 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for certain Airbus Model A300 B4–600, 

B4–600R, and F4–600R series airplanes, 

Model A300 C4–605R Variant F 

airplanes (collectively called Model 

A300–600 series airplanes), and Model 

A310 series airplanes. The MCAI states: 

An operator recently reported two events 

of unreliable airspeed indications. 

Investigations revealed that in both events, a 

Pitot heater resistance was shorted to ground. 

Pitot probes are heated to prevent ice 

accretion. De-icing performance of the Pitot 

probe might be reduced if Pitot probe heater 


ethrower on DSK3G9T082PROD with RULES
47092 Federal Register / Vol. 82, No. 195 / Wednesday, October 11, 2017 / Rules and Regulations 

degrades over time. The magnitude of deicing 

performance reduction will depend on how 

much the heater is degraded. The Pitot probe 

de-icing reduction will be hidden to the crew 

(the heater current detector will not trigger a 

‘‘Heat Fault’’ because in case of short-to-case 

failure the resulting current variation will be 

limited). 

In severe icing conditions, if de-icing 

performances are significantly reduced, it 

may cause unreliable airspeed events, with 

no cockpit effects except erroneous airspeed 

indication(s) displayed on the Primary Flight 

Display (PFD) or the standby airspeed 

indicators. 

Unreliable airspeed indications, if not 

recognized by the crew, could possibly result 

in reduced control of the aeroplane. 

To ensure proper crew awareness of 

unreliable airspeed indication(s) situation, 

Airbus introduced a dedicated Electronic 

Centralised Aircraft Monitoring (ECAM) 

Warning (Indicated Airspeed Discrepancy 

Warning). 

The following configuration is required to 

enable this ECAM Warning: 

—The Flight Warning Computer (FWC) 

standard S17 has to be installed by 

accomplishing Service Bulletins (SB) 

A310–31–2144 or A300–31–6140: This 

requirement was already rendered 

mandatory by EASA AD 2015–0174 [which 

does not have a corresponding FAA AD. 

EASA AD 2015–0174 superseded EASA 

AD 2012–0088 (EASA AD 2012–0088 

corresponds to FAA AD 2012–21–15, 

Amendment 39–17231 (77 FR 67256, 

November 9, 2012))]; 

—The ECAM Symbol Generator Unit (SGU), 

standard W32, Part Number (P/N) 

9612670332 has to be installed, by 

accomplishing Service Bulletins (SB) 

A310–31–2123, A300–31–6124 or SB 

A300–31–6113. 

For the reason described above, this 

[EASA] AD requires a software standard 

upgrade of the ECAM SGU. 

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– 

0515. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Support for the NPRM 

The Air Line Pilots Association, 

International and FedEx expressed 

support for the NPRM. 

Request To Include Historical 

Information 

Airbus requested that we include 

historical information regarding EASA 

AD 2015–0174, which is included in the 

quoted MCAI material in the NPRM. 

Airbus explained that EASA AD 2015– 

0174, dated August 24, 2015, 

superseded EASA AD 2012–0088, dated 

June 25, 2012, which specified 

accomplishment of certain Airbus 

Service Bulletins. Airbus stated that any 

corresponding FAA ADs should also be 

identified. 

We agree that additional historical 

information regarding EASA AD 2015– 

0174 and any corresponding FAA ADs 

would be helpful. We have added the 

requested historical information to the 

quoted MCAI material regarding EASA 

AD 2015–0174, which superseded 

EASA AD 2012–0088, and the 

corresponding FAA AD. 

Requests To Allow Use of a Later 

ECAM SGU Software Standard and 

Related Service Information 

Airbus and FedEx requested that we 

revise the NPRM to allow use of ECAM 

SGU software standard W33, which 

includes the corrections found in ECAM 

SGU software standard W32. 

FedEx also requested that we update 

the NPRM to include new service 

information that provides procedures 

for the upgrade to ECAM SGU software 

standard W33. FedEx mentioned that it 

is preparing to upgrade its fleet to 

ECAM SGU software standard W33. 

We agree with the requests to allow 

use of ECAM SGU software standard 

W33, because ECAM SGU software 

standard W33 includes all of the 

necessary changes from ECAM SGU 

software standard W32. We have revised 

the preamble and regulatory text of this 

final rule, where applicable, to include 

the additional ECAM SGU software 

standard and part number. 

We also agree to add Airbus Service 

Bulletins A300–31–6142, Revision 01, 

dated November 21, 2013, and A310– 

31–2145, Revision 01, dated November 

13, 2013, for accomplishment of the 

installation of ECAM SGU software 

standard W33. We have revised this 

final rule accordingly. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously 

and 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. 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of this AD.

Federal Register / Vol. 82, No. 195 / Wednesday, October 11, 2017 / Rules and Regulations 47093 

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 

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.

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 Bombardier, Inc., Model 

CL–600–1A11 (CL–600), CL–600–2A12 

(CL–601 Variant), and CL–600–2B16 

(CL–601–3A and CL–601–3R Variants) 

airplanes. The NPRM published in the 

Federal Register on July 17, 2017 (82 FR 

32652) (‘‘the NPRM’’). The NPRM was 

prompted by a report of laminated 

shims that may have been improperly 

installed at a certain wing tie beam. The 

NPRM proposed to require revising the 

maintenance or inspection program to 

incorporate certification maintenance 

requirement tasks that introduce revised 

checks of the tie beam. We are issuing 

this AD to detect and correct 

degradation of the structural integrity of 

the affected tie beam, which could 

result in cracking of the pressure floor.

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2016–34,
