Airworthiness Directives; Airbus

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Airbus Model A318, A319, A320, and 

A321 series airplanes. This 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 the oxygen supply 

causing a high temperature oxygen 

generator and mask to fall down. This 

AD requires modifying the passenger 

emergency oxygen container assembly. 

We are issuing 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: This AD becomes effective 

December 2, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of December 2, 2013. 

ADDRESSES: You may examine the AD

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. The 

NPRM published in the Federal 

Register on July 3, 2013 (78 FR 40074). 

The NPRM proposed to correct an 

unsafe condition for the specified 

products. 

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 Mandatory Continuing 

Airworthiness Information, or ‘‘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 examine the MCAI 

in the AD docket on the Internet at 

http://www.regulations.gov/

#!documentDetail;D=FAA-2013-0465- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 40074, July 3, 2013) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed–except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (78 FR 

40074, July 3, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 40074, 

July 3, 2013). 

Costs of Compliance 

We estimate that this AD affects 4 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Modification ..................................................... 2 work-hours × $85 per hour = $170 ............. $0 $170 $680 


wreier-aviles on DSK5TPTVN1PROD with RULES
Federal Register / Vol. 78, No. 208 / Monday, October 28, 2013 / Rules and Regulations 64163 

According to the manufacturer, some 

of the costs of this 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 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. 

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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the MCAI in the 

AD docket on the Internet at http://

www.regulations.gov/

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows:

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: 

2013–20–11 Airbus: Amendment 39–17617. 

Docket No. FAA–2013–0465; Directorate 

Identifier 2012–NM–085–AD.

–132, and –133 airplanes; Model A320–111, 

–211, –212, –214, –231, –232, and –233

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

the Boeing Company Model 747–400 

and –400F series airplanes. This AD was 

prompted by a report of cracks on 

airplanes prior to line number 1308 in 

the forward and aft inner chords of the 

station (STA) 2598 bulkhead, and the 

bulkhead upper and lower webs. This 

AD requires, as applicable, repetitive 

high frequency eddy current (HFEC) and 

low frequency eddy current (LFEC) 

inspections for cracks in the splice 

fitting, support frame, forward and aft 

inner chords, floor support, bulkhead 

upper web on the upper left and right 

side of the bulkhead, and the bulkhead 

lower web on the lower left side of the 

bulkhead and repair if necessary; and 

repetitive post-repair inspections and 

repair if necessary. We are issuing this 

AD to detect and correct cracks in the 

splice fitting, support frame, floor 

support, forward and aft inner chords, 

and the bulkhead upper and lower webs 

of the STA 2598 bulkhead, which could 

adversely affect the structural integrity 

of the airplane. 

DATES:DATES: This AD is effective 

December 2, 2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of December 2, 2013.
