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 Model A318, A319, A320, and 

A321 series airplanes. This proposed 

AD was prompted by the discovery of 

corroded circlips in fuel vent protectors 

(FVP) having a certain part number. 

This proposed AD would require an 

inspection to determine the part number 

and serial number of the FVP, and 

replacement if necessary. We are 

proposing this AD to detect and correct 

corroded circlips. Corroded circlips 

could lead to failure of the circlips and 

consequent movement of the FVP, 

resulting in a reduction of the flame 

protector capability of the FVP 

cartridge, which could result in damage 

to the airplane in case of lightning 

impact or fire on the ground. 

DATES: We must receive comments on 

this proposed AD by February 8, 2016.

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 2014–0234R1, dated December 

11, 2014 (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: 

On each aeroplane wing, a NACA [National 

Advisory committee for Aeronautics] duct 

assembly is installed, including a Fuel Vent 

Protector (FVP) which is used as flame 

arrestor. This FVP is maintained in its NACA 

duct assembly by a circlip (also known as Cclip). Following a wing water pressure test, 

the FVP is removed and dried with heat. 

During an inspection after this test, several 

circlips were reported to be discoloured. 

Investigation revealed that a batch of circlips 

fitted on some FVP Part Number (P/N) 

786073–1–0 have an increased risk of 

corrosion due to a manufacturing quality 

issue. 

This condition, if not detected and 

corrected, could lead to circlip failure and 

consequent FVP movement, reducing the 

flame protector capability of the FVP 

cartridge, possibly resulting in damage to the 

aeroplane in case of lightning impact or fire 

on ground. 

For the reason described above, EASA 

issued AD 2014-0234 to require identification 

by serial number (s/n) of the affected FVP P/ 

N 786073–1–0 and removal from service [and 

replacement with a serviceable part]. 

This [EASA] AD is revised to clarify that 

only maintenance records since August 2012 

should be consulted to demonstrate, as 

required by paragraph (2), that not 

replacement FVP has been installed. 

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–2015– 

7526. 

Related Service Information Under 1 

CFR Part 51 

Airbus has issued Service Bulletin 

A320–28–1221, dated July 21, 2014. The 

service information describes 

procedures for inspecting the FVP to 

determine the part number, and 

replacing the FVP if necessary. 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 of 

this NPRM. 

FAA’s Determination and Requirements 

of This Proposed 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 proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of these same 

type designs. 

Costs of Compliance 

We estimate that this proposed AD 

affects 7 airplanes of U.S. registry. 

We also estimate that it would take 

about 5 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Parts would 

cost $25,640. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be up to $182,455, or 

$26,065 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. 

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 


asabaliauskas on DSK5VPTVN1PROD with PROPOSALS
79744 Federal Register / Vol. 80, No. 246 / Wednesday, December 23, 2015 / Proposed Rules 

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

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: Docket No. FAA–2015–7526; 

Directorate Identifier 2014–NM–217–AD. 

(a) Comments Due Date 

We must receive comments by February 8, 

2016. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to the airplanes specified 

in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) 

of this AD, certificated in any category, all 

manufacturer serial numbers. 

(1) Airbus Model A318–111, –112, –121, 

and –122 airplanes. 

(2) Airbus Model A319–111, –112, –113, 

–114, –115,–131, –132, and –133 airplanes. 

(3) Airbus Model A320–211, –212, –214, 

–231, –232, and –233 airplanes. 

(4) Airbus Model A321–111, –112, –131, 

–211, –212, –213, –231, and –232 airplanes. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 28, Fuel. 

(e) Reason 

This AD was prompted by the discovery of 

corroded circlips in fuel vent protectors 

(FVP) having a certain part number. We are 

issuing this AD to detect and correct 

corroded circlips. Corroded circlips could 

lead to failure of the circlips and consequent 

movement of the FVP, resulting in a 

reduction of the flame protector capability of 

the FVP cartridge, which could result in 

damage to the airplane in case of lightning 

impact or fire on the ground. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Inspection of FVP and Corrective Action 

For airplanes having a manufacturer serial 

number specified in figure 1 to paragraphs (g) 

and (i) of this AD: At the earliest of the times 

specified in paragraphs (h)(1), (h)(2), and 

(h)(3) of this AD, do an inspection to 

determine the part number and serial number 

of the FVP. If the FVP has part number (P/ 

N) 786073–1–0 with a serial number that is 

specified in figure 2 to paragraphs (g) and (i) 

of this AD, and the FVP is not marked ‘‘Amdt 

B,’’ replace the FVP with a serviceable part, 

at the earliest of the times specified in 

paragraphs (h)(1), (h)(2), and (h)(3) of this 

AD, in accordance with the Accomplishment 

Instructions of Airbus Service Bulletin A320– 

28–1221, dated July 21, 2014. A review of 

airplane maintenance records is acceptable in 

lieu of this inspection if the part number and 

serial number of the FVP can be conclusively 

determined from that review.

Airworthiness Directives; Airbus 

Airplanes 

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 Model A300 B4–600, B4–600R, 

and F4–600R series airplanes, and 

Model A300 C4–605R Variant F 

airplanes (collectively called Model 

A300–600 series airplanes); and Model 

A310 series airplanes. This proposed 

AD was prompted by reports of 

premature aging of certain passenger 

chemical oxygen generators that 

resulted in the generators failing to 

activate. This proposed AD would 

require an inspection to determine if 

certain passenger chemical oxygen 

generators are installed and replacement 

of affected passenger chemical oxygen 

generators. We are proposing this AD to 

prevent failure of the passenger 

chemical oxygen generator to activate 

and consequently not deliver oxygen 

during an emergency, possibly resulting 

in injury to airplane occupants. 

DATES: We must receive comments on 

this proposed AD by February 8, 2016. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Fax: 202–493–2251.
