AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Airbus SAS Model A350–941 airplanes. 

This proposed AD was prompted by a 

review of the Airbus A350 structure 

design principles database for type 

definition that revealed that the 

balancer fitting part, installed on the tail 

cone, on a certain frame (FR) has several 

corrosion-resistant stainless steel nuts 

that do not meet the requirements for 

protection against corrosion. This 

proposed AD would require application 

of a new additional overcoat sealant and 

elastic varnish on the affected nuts and 

fasteners. We are proposing this AD to 

address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by October 1, 2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR

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 2018–0123, dated June 4, 2018 

(referred to after this as the Mandatory 

Continuing Airworthiness Information, 

or ‘‘the MCAI’’), to correct an unsafe 

condition for certain Airbus SAS Model 

A350–941 airplanes. The MCAI states: 

Following a complete review of the Airbus 

A350 structure design principles database for 

type definition, it was revealed that the 

balancer fitting part, installed on the tail 

cone, lower section of Frame (FR) 103, has 

several corrosion resistant stainless steel nuts 

installed on elementary aluminium parts, 

which does not meet the requirements for 

protection against corrosion. 

This condition, if not corrected, could 

reduce the structural integrity of the 

aeroplane. 

To address this unsafe condition, Airbus 

developed production mod 110319 to 

improve protection against corrosion, and 

issued the SB [Airbus Service Bulletin A350– 

53–P024] to provide modification 

instructions for in-service pre-mod 

aeroplanes. At the same time the production 

mod 110348 is equivalent to in-service 

solution. 

For the reasons described above, this 

[EASA] AD requires a modification, adding 

new additional overcoat sealant and elastic 

varnish on the affected nuts and fastener 

heads.

Related Service Information Under 1 

CFR Part 51 

Airbus SAS has issued Service 

Bulletin A350–53–P024, dated April 3, 

2018. This service information describes 

procedures for the application of a new 

additional overcoat sealant and elastic 

varnish on the affected nuts and 

fasteners. 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 

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 proposing this 

AD because we evaluated all the 

relevant information and determined 

the unsafe condition described 

previously is likely to exist or develop 

on other products of the same type 

design. 

Proposed Requirements of This NPRM 

This proposed AD would require 

accomplishing the actions specified in 

the service information described 

previously. 

Costs of Compliance 

We estimate that this proposed AD 

affects 7 airplanes of U.S. registry. We 

estimate the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

2 work-hours × $85 per hour = $170 .......................................................................................... $500 $670 $4,690 

According to the manufacturer, some 

or all of the costs of this proposed AD 

may be covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage for affected individuals. As a 

result, we have included all known 

costs in our cost estimate. 

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 proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference,

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 adding 

the following new airworthiness 

directive (AD): 

Airbus SAS: Docket No. FAA–2018–0758; 

Product Identifier 2018–NM–093–AD. 

(a) Comments Due Date 

We must receive comments by October 1, 

2018. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Airbus SAS Model 

A350–941 airplanes, certificated in any 

category, except those on which Airbus 

modification 110319 or Airbus modification 

110348 has been embodied in production. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 53, Fuselage. 

(e) Reason 

This AD was prompted by a review of the 

Airbus A350 structure design principles 

database for type definition that revealed that 

the balancer fitting part, installed on the tail 

cone, lower section of frame (FR) 103, has 

several corrosion-resistant stainless steel nuts 

installed on elementary aluminum parts, and 

this configuration does not meet the 

requirements for protection against corrosion. 

We are issuing this AD to address this 

condition, which if not corrected, could 

reduce the structural integrity of the airplane.

SUMMARY: We propose to adopt an 

airworthiness directive (AD) for all The 

Boeing Company Model 757–200 series 

airplanes. This proposed AD was 

prompted by reports of uncommanded 

movement of the captain’s and first 

officer’s seats. This proposed AD would 

require, for the captain’s and first 

officer’s seats, repetitive horizontal 

actuator identifications, repetitive 

checks of the horizontal movement 

system (HMS), a detailed inspection of 

the HMS, as applicable, and applicable 

on-condition actions. This proposed AD 

would also require a general visual 

inspection to determine seat part 

numbers of the captain’s and first 

officer’s seats, a cable adjustment check 

on seats with certain seat part numbers, 

and applicable on-condition actions. We 

are proposing this AD to address the 

unsafe condition on these products.
