AD if it is approved by the Boeing 

Commercial Airplanes Organization 

Designation Authorization (ODA) that has 

been authorized by the Manager, Seattle ACO 

Branch, FAA, to make those findings. To be 

approved, the repair method, modification 

deviation, or alteration deviation must meet 

the certification basis of the airplane, and the 

approval must specifically refer to this AD. 

(4) For service information that contains 

steps that are labeled as RC, the provisions 

of paragraphs (j)(4)(i) and (j)(4)(ii) of this AD 

apply. 

(i) The steps labeled as RC, including 

substeps under an RC step and any figures 

identified in an RC step, must be done to 

comply with the AD. If a step or substep is 

labeled ‘‘RC Exempt,’’ then the RC 

requirement is removed from that step or 

substep. An AMOC is required for any 

deviations to RC steps, including substeps 

and identified figures. 

(ii) Steps not labeled as RC may be 

deviated from using accepted methods in 

accordance with the operator’s maintenance 

or inspection program without obtaining 

approval of an AMOC, provided the RC steps, 

including substeps and identified figures, can 

still be done as specified, and the airplane 

can be put back in an airworthy condition.

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 A330–200, –200F, 

and –300 series airplanes. This 

proposed AD was prompted by a 

revision of the airworthiness limitations 

section (ALS), which provides new and 

more restrictive maintenance 

requirements and airworthiness 

limitations for airplane structures and 

systems. This proposed AD would 

require revising the maintenance or 

inspection program to incorporate new 

maintenance requirements and 

airworthiness limitations. We are 

proposing this AD to address the unsafe 

condition on these products. 

DATES: We must receive comments on 

this proposed AD by October 15, 2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2017–0228, 

dated November 21, 2017 (referred to 

after this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for all Airbus SAS Model A330 and 

A340 series airplanes. The MCAI states: 

The airworthiness limitations are currently 

defined and published in the Airbus A330 

and A340 Airworthiness Limitations Section 

(ALS) documents. The airworthiness 

limitations applicable to the System 

Equipment Maintenance Requirements, 

which are approved by EASA, are specified 

in Airbus A330 and A340 ALS Part 4. Failure 

to comply with these instructions could 

result in an unsafe condition. 

EASA issued AD 2016–0011 [which 

corresponds to FAA AD 2017–05–10, 

Amendment 39–18821 (82 FR 13379, March 

13, 2017) (‘‘AD 2017–05–10’’)] to require the 

actions as specified in Airbus A330 and A340 

ALS Part 4 at Revision 05 and Revision 04, 

respectively. 

Since this [EASA] AD was issued, Airbus 

published Revision 06 and Revision 05, 

respectively, of Airbus A330 and A340 ALS 

Part 4, which introduce new and more 

restrictive maintenance requirements and/or 

airworthiness limitations. 

For the reason described above, this 

[EASA] AD retains the requirements of EASA 

AD 2016–0011, which is superseded, and 

requires accomplishment of the actions 

specified in Airbus A330 ALS Part 4 Revision 

06, or A340 ALS Part 4 Revision 05, as 

applicable. 

The unsafe condition is reduced 

control of the airplane due to the failure 

of system components. 

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–2018– 

0788. 

Relationship Between Proposed AD and 

AD 2017–05–10 

This NPRM would not propose to 

supersede AD 2017–05–10. Rather, we 

have determined that a stand-alone AD 

would be more appropriate to address 

the changes in the MCAI. This NPRM 

would require revising the maintenance 

or inspection program to incorporate 

new maintenance requirements and 

airworthiness limitations. 

Accomplishment of the proposed 

actions would then terminate all of the 

requirements of AD 2017–05–10. 

Related Service Information Under 1 

CFR Part 51 

Airbus SAS has issued A330 

Airworthiness Limitations Section 

(ALS) Part 4, System Equipment 

Maintenance Requirements (SEMR), 

Revision 06, dated September 18, 2017. 

This service information describes 

preventative maintenance requirements 

and associated airworthiness limitations 

applicable to aircraft systems 

susceptible to aging effects. 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 

revising the maintenance or inspection 

program to incorporate new 

maintenance requirements and 

airworthiness limitations. 

Differences Between This Proposed AD 

and the MCAI or Service Information 

EASA AD 2017–0228, dated 

November 21, 2017, specifies that if 

there are findings from the ALS 

inspection tasks, corrective actions must 

be accomplished in accordance with 

Airbus SAS maintenance 

documentation. However, this proposed 

AD does not include that requirement. 

Operators of U.S.-registered airplanes 

are required by general airworthiness 

and operational regulations to perform 

maintenance using methods that are 

acceptable to the FAA. We consider 

those methods to be adequate to address 

any corrective actions necessitated by 

the findings of ALS inspections required 

by this proposed AD. 

This proposed AD does not include 

Model A340 series airplanes in the 

Applicability. AD 2014–23–17, 

Amendment 39–18033 (79 FR 71304, 

December 2, 2014), currently addresses 

the identified unsafe condition for 

Model A340 series airplanes. We have 

also added EASA AD 2017–0228, dated 

November 21, 2017, to the required 

airworthiness action list (RAAL) for 

Model A340 series airplanes. 

Airworthiness Limitations Based on 

Type Design 

The FAA recently became aware of an 

issue related to the applicability of ADs 

that require incorporation of an ALS 


daltland on DSKBBV9HB2PROD with PROPOSALS
44512 Federal Register / Vol. 83, No. 170 / Friday, August 31, 2018 / Proposed Rules 

revision into an operator’s maintenance 

or inspection program. 

Typically, when these types of ADs 

are issued by civil aviation authorities 

of other countries, they apply to all 

airplanes covered under an identified 

type certificate (TC). The corresponding 

FAA AD typically retains applicability 

to all of those airplanes. 

In addition, U.S. operators must 

operate their airplanes in an airworthy 

condition, in accordance with 14 CFR 

91.7(a). Included in this obligation is the 

requirement to perform any 

maintenance or inspections specified in 

the ALS, and in accordance with the 

ALS as specified in 14 CFR 43.16 and 

91.403(c), unless an alternative has been 

approved by the FAA. 

When a TC is issued for a type design, 

the specific ALS, including revisions, is 

a part of that type design, as specified 

in 14 CFR 21.31(c). 

The sum effect of these operational 

and maintenance requirements is an 

obligation to comply with the ALS 

defined in the type design referenced in 

the manufacturer’s conformity 

statement. This obligation may 

introduce a conflict with an AD that 

requires a specific ALS revision if new 

airplanes are delivered with a later 

revision as part of their type design. 

To address this conflict, the FAA has 

approved alternative methods of 

compliance (AMOCs) that allow 

operators to incorporate the most recent 

ALS revision into their maintenance/ 

inspection programs, in lieu of the ALS 

revision required by the AD. This 

eliminates the conflict and enables the 

operator to comply with both the AD 

and the type design. 

However, compliance with AMOCs is 

normally optional, and we recently 

became aware that some operators 

choose to retain the AD-mandated ALS 

revision in their fleet-wide 

maintenance/inspection programs, 

including those for new airplanes 

delivered with later ALS revisions, to 

help standardize the maintenance of the 

fleet. To ensure that operators comply 

with the applicable ALS revision for 

newly delivered airplanes containing a 

later revision than that specified in an 

AD, we plan to limit the applicability of 

ADs that mandate ALS revisions to 

those airplanes that are subject to an 

earlier revision of the ALS, either as part 

of the type design or as mandated by an 

earlier AD. 

This proposed AD therefore would 

apply to Airbus SAS airplanes 

identified in paragraph (c) of this 

proposed AD with an original certificate 

of airworthiness or original export 

certificate of airworthiness that was 

issued on or before the date of the ALS 

revision identified in this proposed AD. 

Operators of airplanes with an original 

certificate of airworthiness or original 

export certificate of airworthiness 

issued after that date must comply with 

the airworthiness limitations specified 

as part of the approved type design and 

referenced on the TC data sheet. 

Costs of Compliance 

We estimate that this proposed AD 

affects 104 airplanes of U.S. registry. 

We have determined that revising the 

maintenance or inspection program 

takes an average of 90 work-hours per 

operator, although we recognize that 

this number may vary from operator to 

operator. In the past, we have estimated 

that this action takes 1 work-hour per 

airplane. Since operators incorporate 

maintenance or inspection program 

changes for their affected fleet(s), we 

have determined that a per-operator 

estimate is more accurate than a perairplane estimate. Therefore, we 

estimate the total cost per operator to be 

$7,650 (90 work-hours × $85 per workhour). 

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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Airbus SAS Model A330–200 Freighter 

series airplanes, Model A330–200 and 

–300 series airplanes, and Model A340– 

200 and –300 series airplanes. This 

proposed AD was prompted by defects 

found during production tests of ram air 

turbine (RAT) units; investigation 

revealed that the defects were due to 

certain RAT hydraulic pumps having an 

alternative manufacturing process of the 

pump pistons. This proposed AD would 

require replacing any defective RAT 

hydraulic pump with a serviceable part 

and re-identifying the RAT module part 

number. We are proposing this AD to 

address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by October 15, 2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2018–0062, 

dated March 20, 2018 (referred to after 

this as the Mandatory Continuing 

Airworthiness Information, or ‘‘the 

MCAI’’), to correct an unsafe condition 

for all Airbus SAS Model A330–200 

Freighter series airplanes, Model A330– 

200 and –300 series airplanes, and 

Model A340–200 and –300 series 

airplanes. The MCAI states: 

Four A330 RAT units were returned to the 

supplier due to low discharge pressure. 

These defects were detected during Airbus 

production tests. Subsequent investigations 

by the RAT manufacturer UTAS (formerly 

Hamilton Sundstrand) revealed that some 

RAT hydraulic pumps, [part number] P/N 

5916430, were involved in an alternative 

manufacturing process of the pump pistons. 

This resulted in form deviations (rough 

surface finish and sharp edges), which 

caused excessive wear and damage to the 

bore where the pistons moved. 

This condition, if not corrected, could lead 

to low performance of the pump, possibly 

resulting in reduced control of the aeroplane, 

particularly if occurring following a total 

engine flame out, or during a total loss of 

normal electrical power generation. 

To address this potential unsafe condition, 

Airbus published [service bulletin] SB A330– 

29–3130 and SB A340–29–4098, providing 

instructions for identification and 

replacement of the affected parts. 

For the reasons described above, this 

[EASA] AD requires replacement of the 

affected parts. This [EASA] AD also requires 

re-identification of the RAT module. 

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–2018– 

0764. 

Other Related Rulemaking 

The FAA issued AD 2016–14–01, 

Amendment 39–18582 (81 FR 44983, 

July 12, 2016); corrected (81 FR 51097, 

August 3, 2016) (‘‘AD 2016–14–01’’). AD 

2016–14–01 applies to certain Airbus 

SAS Model A330–200 Freighter series 

airplanes; Model A330–200 and A330– 

300 series airplanes; Model A340–200 

and A340–300 series airplanes; Model 

A340–500 series airplanes; and Model 

A340–600 series airplanes. AD 2016– 

14–01 requires identification of the 

manufacturer, part number, and serial 

number of the RAT, and reidentification and modification of the 

RAT if necessary. AD 2016–14–01 was 

prompted by a report indicating that, 

during an operational test of a RAT, the 

RAT did not deploy in automatic mode. 

AD 2016–14–01 was issued to prevent 

non-deployment of the RAT, which, 

following a total engine flame-out, or 

during a total loss of normal electrical 

power generation, could result in 

reduced control of the airplane.
