Airworthiness Directives; Airbus

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Supplemental notice of 

proposed rulemaking (NPRM); 

reopening of comment period. 

SUMMARY: We are revising an earlier 

proposed airworthiness directive (AD) 

for certain Airbus Model A319 and 

A320 series airplanes. That NPRM 

proposed to require modification of the 

off-wing escape slide (OWS) enclosures 

on both sides. That NPRM was 

prompted by a report of a torn out 

aspirator due to the aspirator interfering 

with the extrusion lip of the OWS 

enclosure during the initial stage of the 

deployment sequence. This action 

revises that NPRM by adding an 

airplane model to the applicability. We 

are proposing this AD to prevent both 

off-wing exits from being inoperative, 

which, during an emergency, would 

impair the safe evacuation of occupants, 

possibly resulting in personal injuries. 

Since this action imposes an additional 

burden over that proposed in the NPRM, 

we are reopening the comment period to 

allow the public the chance to comment 

on these proposed changes. 

DATES: We must receive comments on 

this proposed AD by July 26, 2012.

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this proposed AD. 

Discussion 

We proposed to amend 14 CFR part 

39 with an earlier NPRM for the 

specified products, which was 

published in the Federal Register on 

November 2, 2011 (76 FR 67625). That 

earlier NPRM proposed to require 

actions intended to address the unsafe 

condition for certain Airbus Model 

A319 and A320 series airplanes. 

Comments 

We have considered the following 

comment received on the earlier NPRM 

(76 FR 67625, November 2, 2011). 

Request To Revise the Applicability of 

the NPRM (76 FR 67625, November 2, 

2011) 

Airbus requested we revise the 

applicability of the NPRM (76 FR 67625, 

November 2, 2011) to include Model 

A318 series airplanes, which would 

match the applicability specified in 

EASA Airworthiness Directive (AD) 

2010–0210, dated October 21, 2010 

(corrected October 27, 2010). Airbus 

stated that the applicability of the EASA 

AD identifies all airplane models that 

have been certified with the capability 

to be fitted with Air Cruisers/Aerazur 

part number (P/N) D31865–109, –110, 

–209, or –210 OWS, which are the only 

OWS affected by the identified unsafe 

condition. 

Airbus added that some airplanes that 

were delivered with Airbus 

Modification 30088 and are currently in 

service could be fitted with one of those 

four OWS by the time the FAA AD 

becomes effective, and this explains 

why Model A318 series airplanes were 

included in the applicability of the 

EASA AD despite the fact that no Model 

A318 series airplane was delivered with 

an affected OWS. Airbus noted that the 

reason Model A318 series airplanes 

were not included in the Airbus service 

information is because its effectivity is 

based on aircraft configuration at the 

time of production delivery. 

We concur with the commenter’s 

request. For the reasons provided by the 

commenter, we have revised paragraph 

(c) of this supplemental NPRM to 

include Model A318 series airplanes 

and to remove the reference to airplanes 

delivered with Airbus Modification 

30088. 

Request To Revise Paragraph (h) of the 

NPRM (76 FR 67625, November 2, 

2011) 

Airbus noted that paragraph (h) of the 

NPRM (76 FR 67625, November 2, 2011) 

is more restrictive than the equivalent 

paragraphs in the EASA AD. 

We agree. We find that paragraph (h) 

of the NPRM (76 FR 67625, November 

2, 2011) need not be more restrictive 

than that of the EASA AD with regard 

to the time for allowing spare parts to 

be installed. We have revised that 

paragraph to prohibit installation of 

spare parts ‘‘after accomplishing the 

modification required by paragraph (g) 

of this AD.’’ However, paragraph (4) of 

EASA AD 2010–0210, dated October 21, 

2010 (corrected October 27, 2010), does 

not apply to the airplanes identified in 

the applicability of this supplemental 

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 the same 

type design. 

Certain changes described above 

expand the scope of the earlier NPRM 

(76 FR 67625, November 2, 2011). As a 

result, we have determined that it is 

necessary to reopen the comment period 

to provide additional opportunity for 

the public to comment on this proposed 

AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 694 products of U.S. 

registry. We also estimate that it would 

take about 14 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $0 per product. 

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 $825,860, or $1,190 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 

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.

of the estimated costs to comply with
