SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA Airworthiness 

Directive 2017–0129, dated July 25, 

2017 (referred to after this as the 

Mandatory Continuing Airworthiness 

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

an unsafe condition for all Airbus 

Model A350–941 airplanes. The MCAI 

states: 

Prompted by in-service events where a loss 

of communication occurred between some 

avionics systems and avionics network, 

analysis has shown that this may occur after 

149 hours of continuous aeroplane power-up. 

Depending on the affected aeroplane systems 

or equipment, different consequences have 

been observed and reported by operators, 

from redundancy loss to complete loss on a 

specific function hosted on common remote 

data concentrator and core processing input/ 

output modules. 

This condition, if not corrected, could lead 

to partial or total loss of some avionics 

systems or functions, possibly resulting in an 

unsafe condition. 

To address this potential unsafe condition, 

Airbus issued Alert Operators Transmission 

(AOT) A42P001–17 * * * to provide 

instructions to reset the internal timer. 

For the reasons described above, this 

[EASA] AD requires repetitive on ground 

power cycles (resets). 

This [EASA] AD is considered to be an 

interim measure and further AD action may 

follow. 

You may examine the MCAI on the 

Internet at http://www.regulations.gov 

by searching for and locating Docket No. 

FAA–2017–0808. 

Related Service Information Under 1 

CFR Part 51 

Airbus has issued Alert Operators 

Transmission (AOT) A42P001–17, dated 

June 30, 2017, which describes 

procedures for repetitive on-ground 

power cycles to reset the internal timer. 

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. 

FAA’s Determination and Requirements 

of This AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are issuing this 

AD because we evaluated all pertinent 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of these same 

type designs. 

FAA’s Determination of the Effective 

Date 

An unsafe condition exists that 

requires the immediate adoption of this 


asabaliauskas on DSKBBXCHB2PROD with RULES
42580 Federal Register / Vol. 82, No. 174 / Monday, September 11, 2017 / Rules and Regulations 

AD. The FAA has found that the risk to 

the flying public justifies waiving notice 

and comment prior to adoption of this 

rule because a loss of communication 

between some avionics systems and the 

avionics network could lead to partial or 

total loss of some avionics systems or 

functions. Therefore, we determined 

that notice and opportunity for public 

comment before issuing this AD are 

impracticable and that good cause exists 

for making this amendment effective in 

fewer than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not precede it by notice and 

opportunity for public comment. We 

invite you to send any written relevant 

data, views, or arguments about this AD. 

Send your comments to an address 

listed under the ADDRESSES section. 

Include ‘‘Docket No. FAA–2017–0808; 

Product Identifier 2017–NM–102–AD’’ 

at the beginning of your comments. We 

specifically invite comments on the 

overall regulatory, economic, 

environmental, and energy aspects of 

this AD. We will consider all comments 

received by the closing date and may 

amend this AD based on those 

comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this AD. 

Costs of Compliance 

We estimate that this AD affects 2 

airplanes of U.S. registry. 

We also estimate that it will 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 $170, 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 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.

set outside acceptable limits for a mistrimmed takeoff condition. This AD 

requires, depending on airplane 

configuration, replacing certain pitch 

trim light plates, relocating certain 

position warning horn switches, 

revising certain software, removing a 

certain placard, and doing related 

investigative and corrective actions if 

necessary. We are issuing this AD to 

address the unsafe condition on these 

products.

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 The Boeing Company 

Model 737–700 and –700C series 

airplanes. The NPRM published in the 

Federal Register on June 28, 2016 (81 

FR 41894). The NPRM was prompted by 

a report that, for airplanes with blended 

winglets, the nose-up pitch trim limit 

and associated warning for the 

horizontal stabilizer control system will 

allow the stabilizer position to be set 

outside acceptable limits for a mistrimmed takeoff condition. The NPRM 

proposed to require, depending on 

airplane configuration, replacing the 

pitch trim light plates on the flight deck 

control stand, relocating the position 

warning horn switches of the horizontal 

stabilizer, revising the software, 

removing the placard, and doing related 

investigative and corrective actions if 

necessary. We are issuing this AD to 

prevent a stabilizer position set outside 

acceptable limits for a mis-trimmed 

takeoff condition. Settings outside of the 

appropriate pitch trim limits could 

result in loss of controllability of the 

airplane during takeoff. 

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.
