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 A330–200, –200 

Freighter, and –300 series airplanes; and 

all Airbus Model A340–200, –300, –500, 

and –600 series airplanes. This 

proposed AD was prompted by reports 

of premature aging of certain chemical 

oxygen generators in the passenger 

compartment that resulted in failure of 

the generators to activate. This proposed 

AD would require inspecting to 

determine if certain passenger chemical 

oxygen generators are installed, and 

replacement of affected generators. We 

are proposing this AD to prevent failure 

of the chemical oxygen generator to 

activate during an emergency situation, 

which could result in unavailability of 

oxygen and possible incapacitation of 

the occupants. 

DATES: We must receive comments on 

this proposed AD by October 15, 2015. 

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 Airworthiness 

Directive 2015–0119, dated June 24, 

2015 (referred to after this as the 

Mandatory Continuing Airworthiness 

Information, or ‘‘the MCAI’’), to correct 

an unsafe condition for all Airbus 

Model A330–200, –200 Freighter, and 

–300 series airplanes; and Model A340– 

200, –300, –500, and –600 series 

airplanes. The MCAI states: 

Reports have been received indicating 

premature ageing of certain passenger 

chemical oxygen generators, Part Number (P/ 

N) 1170242–XX, manufactured by B/E 

Aerospace. Some operators reported that 

when they tried to activate generators, some 

older units failed to activate. Given the 

number of failed units reported, all the 

generators manufactured in 1999, 2000, and 

2001 must be considered unreliable. 

This condition, if not corrected, could lead 

to failure of the generator to activate and 

consequently not deliver oxygen during an 

emergency, possibly resulting in injury to 

aeroplane occupants. 

To address this potential unsafe condition, 

Airbus issued Alert Operators Transmission 

(AOT) A35L007–14, making reference to B/ 

E Aerospace Service Information Letter (SIL) 

D1019–01 (currently at Revision 1) and B/E 

Aerospace Service Bulletin (SB) 117042–35– 

001. Consequently, EASA issued AD 2014– 

0277 to require identification and 

replacement of the affected oxygen 

generators. 

Since EASA AD 2014–0277 was issued, 

and following new investigation results, 

EASA has decided to introduce a life 

limitation concerning all P/N 117042–XX 

chemical oxygen generators, manufactured 

by B/E Aerospace. 

For the reason described above, this EASA 

AD retains the requirements of EASA AD 

2014–0277, which is superseded, expands 

the scope of the AD to include chemical 


rmajette on DSK7SPTVN1PROD with PROPOSALS

oxygen generators manufactured after 2001, 

and requires their removal from service 

before exceeding 10 years since date of 

manufacture.

Related Service Information Under 1 

CFR Part 51 

Airbus has issued Alert Operators 

Transmission (AOT) A35L007–14, 

Revision 01, June 17, 2015; including 

Appendix A. B/E Aerospace has issued 

Service Bulletin 117042–35–001, dated 

December 10, 2014. The service 

information describes procedures for 

inspecting to determine if certain 

passenger chemical oxygen generators 

are installed, and replacing affected 

generators. 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 91 airplanes of U.S. registry. 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Inspection .......................... 1 work-hour × $85 per 

hour = $85.

$0 ...................................... $85 .................................... $7,735. 

Replacement ..................... 1 work hour × $85 per 

hour = $85.

$1,000 per oxygen generator.$1,085 per oxygen generator.$98,735 for one oxygen 

generator. 

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.
