Airworthiness Directives; Airbus

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for all 

Model A318, A319, A320, and A321 

series airplanes. This proposed AD was 

prompted by a determination that 

oxygen generators installed on a certain 

batch of passenger emergency oxygen 

container assemblies might become 

detached by extreme pulling of the mask 

tube at the end of oxygen supply 

causing a high temperature oxygen 

generator and mask to fall down. This 

proposed AD would require modifying 

the passenger emergency oxygen 

container assembly. We are proposing 

this AD to prevent a high temperature 

oxygen generator and mask from falling 

down and possibly resulting in an 

ignition source in the passenger 

compartment, injury to passengers, and 

reduced availability of supplemental 

oxygen. 

DATES: We must receive comments on 

this proposed AD by August 19, 2013. 

ADDRESSES: You may send comments by 

any of the following methods:

instructions for submitting comments.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2012–0055, 

dated April 3, 2012 (referred to after this 

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

condition for the specified products. 

The MCAI states: 

It has been determined that oxygen 

generators, installed on a specific batch of 

Type 1 (22 minute) passenger emergency 

oxygen container assemblies, may become 

detached by extreme pulling of the mask tube 

at the end of oxygen supply. Investigations 

revealed that such detachment can be caused 

by the increase in temperature towards the 

end of the generator operation, which may 

weaken the plastic housing in the attachment 

area of the bracket. 

This condition, if not corrected, could 

make the rivets slip through the plastic 

housing, causing a ‘hot’ oxygen generator and 

mask to fall down, possibly resulting in 

injury to passengers. 

For the reasons described above, this 

[EASA] AD requires modification of the 

affected oxygen container assemblies. This 

[EASA] AD also prohibits the installation of 

the affected (unmodified) containers on any 

aeroplane as replacement parts. 

The modification consists of adding a 

reinforcement plate at the rear outside 

of the container and adding two washers 

to the rivets at the inside of the 

container to prevent the generator from 

detaching. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Airbus has issued the following 

service bulletins. 

• Service Bulletin A320–35–1049, 

dated June 15, 2011. 

• Service Bulletin A320–35–1053, 

dated June 15, 2011. 

• Service Bulletin A320–35–1054, 

dated June 15, 2011. 

• Service Bulletin A320–35–1055, 

dated June 15, 2011. 

• Service Bulletin A320–35–1056, 

dated June 15, 2011. 

• Service Bulletin A320–35–1057, 

dated June 15, 2011. 

• Service Bulletin A320–35–1058, 

dated June 15, 2011. 

The actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 128 / Wednesday, July 3, 2013 / Proposed Rules 40075 

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 the same 

type design. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 4 products of U.S. registry. 

We also estimate that it would take 

about 2 work-hours per oxygen 

container assembly to comply with the 

basic requirements of this proposed AD. 

The average labor rate is $85 per workhour. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$680 per oxygen container assembly. 

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 

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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part

continues to read as follows: 

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

■ 2. The FAA amends § 39.13 by adding 

the following new AD:

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: This action proposes to 

establish Class E airspace extending 

upward from 700 feet above the surface 

at Metropolitan Oakland International 

Airport, Oakland, CA. Controlled 

airspace is necessary to accommodate 

aircraft using the Area Navigation 

(RNAV) Global Positioning System 

(GPS) standard instrument approach 

procedures at the airport. This action 

would also modify Class E surface 

airspace designated as an extension to 

Class C airspace by removing the 

navigation aids from the airspace 

designation. The FAA is proposing this 

action to enhance the safety and 

management of aircraft operations at the 

airport.
