SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2014–26–10, 

Amendment 39–18061 (80 FR 2813, 

January 21, 2015) (‘‘AD 2014–26–10’’). 

AD 2014–26–10 applied to all Airbus 

Model A318, A319, A320, and A321 

series airplanes. The NPRM published 

in the Federal Register on April 13, 

2017 (82 FR 17770). The NPRM was 

prompted by a determination that more 

restrictive maintenance instructions and 

airworthiness limitations are necessary. 

The NPRM proposed to require revising 

the maintenance or inspection program, 

as applicable, to incorporate new or 

revised airworthiness limitation 

requirements. The NPRM also proposed 

to remove airplanes from the 

applicability. We are issuing this AD to 

mitigate the risks associated with aging 

effects of airplane systems. Such aging 

effects could change the characteristics 

of the systems leading to an increased 

potential for failure, which could result 

in failure of certain life-limited parts, 

and reduced structural integrity or 

reduced controllability 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 2016–0093, 

dated May 13, 2016 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for all Airbus Model A318, A319, A320, 

and A321 series airplanes. The MCAI 

states: 

The airworthiness limitations for Airbus 

A320 family aeroplanes are currently defined 

and published in Airbus A318/A319/A320/ 

A321 Airworthiness Limitations Section 

(ALS) documents. The airworthiness 

limitations applicable to the System 

Equipment Maintenance Requirements, 

which are approved by [European Aviation 

Safety Agency] EASA, are specified in ALS 

Part 4. 

The instructions contained in the ALS Part 

4 have been identified as mandatory actions 

for continued airworthiness. Failure to 

comply with these instructions could result 

in an unsafe condition. 

Previously, EASA issued AD 2013–0146 

[which corresponds to FAA AD 2014–26–10] 

to require accomplishment of all 

maintenance actions as described in ALS Part 

4 at Revision 01. The new ALS Part 4 

Revision 03 (hereafter referred to as ‘the ALS’ 

in this AD) includes new and/or more 

restrictive requirements. ALS Part 4 Revision 

03, issue 02, has been released to include 

editorial changes. 

For the reason described above, this 

[EASA] AD retains the requirements of EASA 

AD 2013–0146, which is superseded, and 

requires accomplishment of the actions 

specified in the ALS. 

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– 

0248. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Camp Systems International, Daniel 

Systems Inc., and United Airlines 

supported the NPRM. 

Request To Incorporate Current ALS 

Revision 

American Airlines (AAL) asked that a 

provision be incorporated into the 

proposed AD to approve use of Airbus 

A318/A319/A320/A321 ALS Part 4, 

‘‘System Equipment Maintenance 

Requirements (SEMR)’’, Revision 05, 

dated April 6, 2017 (‘‘ALS Part 4, 

Revision 05’’), as an additional means of 

compliance with the maintenance or 

inspection program. AAL stated that 

ALS Part 4, Revision 05 is the latest 

revision level for ALS Part 4, and 

approving it would potentially alleviate 

a future alternative method of 

compliance (AMOC) request. 

We acknowledge the commenter’s 

concern. We have issued global AMOCs 

to AD 2014–26–10, which allow all 

operators of U.S.-registered airplanes to 

use Airbus A318/A319/A320/A321 ALS 

Part 4, ‘‘System Equipment Maintenance 

Requirements (SEMR)’’, Revision 04, 

dated July 6, 2016, and Airbus A318/ 

A319/A320/A321 ALS Part 4, ‘‘System 

Equipment Maintenance Requirements 

(SEMR)’’, Revision 05, dated April 6, 

2017. These AMOCs are included in 

paragraph (k)(1)(ii) of this AD, which 

states that AMOCs approved previously 

for AD 2014–26–10 are approved as 

AMOCs for the corresponding 

provisions of paragraph (g) of this AD. 

In addition, these AMOCs are also 

applicable to the revision required by 

paragraph (i) of this AD. Therefore, we 

have added paragraph (k)(1)(iii) to this 

AD to specify the previous AMOCs that 

are approved for the provisions of 

paragraph (i) of this AD. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the change 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. 

Related Service Information Under 1 

CFR part 51 

Airbus has issued Airbus A318/A319/ 

A320/A321 ALS Part 4, ‘‘System

information describes preventive 

maintenance requirements and includes 

updated inspections and intervals to be 

incorporated into the maintenance or 

inspection program. 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 1,032 

airplanes of U.S. registry.

44902 Federal Register / Vol. 82, No. 186 / Wednesday, September 27, 2017 / Rules and Regulations 

The actions required by AD 2014–26– 

10, and retained in this AD take about 

1 work-hour per product, at an average 

labor rate of $85 per work-hour. Based 

on these figures, the estimated cost of 

the actions that are required by AD 

2014–26–10 is $85 per product. 

We also estimate that it would take 

about 1 work-hour per product to 

comply with the basic requirements of 

this AD. The average labor rate is $85 

per work-hour. Based on these figures, 

we estimate the cost of this AD on U.S. 

operators to be $87,720, or $85 per 

product. 

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 proposed 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 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 under 

the criteria of the Regulatory Flexibility 

Act.

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by 

removing Airworthiness Directive (AD) 

2014–26–10, Amendment 39–18061 (80 

FR 2813, January 21, 2015), and adding 

the following new AD: 

2017–19–24 Airbus: Amendment 39–19054;

after revising the maintenance or inspection 

program; whichever occurs later. 

Accomplishing the actions specified in 

paragraph (i) of this AD terminates the 

requirements of this paragraph. 

(h) Retained Requirement: No Alternative 

Actions or Intervals, With New Paragraph 

Reference 

This paragraph restates the requirements of 

paragraph (h) of AD 2014–26–10, with a new 

paragraph reference. Except as required by 

paragraph (i) of this AD, after 

accomplishment of the revision required by 

paragraph (g) of this AD, no alternative 

actions (e.g., inspections) or intervals may be 

used unless the actions or intervals are 

approved as an alternative method of 

compliance (AMOC) in accordance with the 

procedures specified in paragraph (k)(1) of 

this AD. 

(i) New Requirement: Maintenance or

Airworthiness Directives; Airbus

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2015–15– 

10, which applied to all Airbus Model 

A318, A319, A320, and A321 series 

airplanes. AD 2015–15–10 required 

repetitive inspections of the trimmable 

horizontal stabilizer actuator (THSA) for 

damage, and replacement if necessary; 

and replacement of the THSA after 

reaching a certain life limit. This AD 

requires repetitive detailed inspections 

of certain THSAs, and related 

investigative and corrective actions if 

necessary. This AD was prompted by 

the establishment of an additional life 

limit for the THSA, based on flight 

cycles. In addition, the THSA 

manufacturer has issued service 

information which, when accomplished, 

increases the life limit of the THSA. We 

are issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective November 1, 

2017. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 1, 2017. 

ADDRESSES: For service information
