ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Airbus transport category 

airplanes. This proposed AD would 

require replacing the existing cabin 

altitude indicator in the cabin pressure 

control panel with a new, improved 

cabin altitude indicator. This proposed 

AD is prompted by a report of injuries 

occurring on in-service airplanes when 

crewmembers forcibly initiated opening 

of passenger/crew doors against residual 

pressure causing the doors to rapidly 

open. We are proposing this AD to 

prevent injury to crewmembers, and 

subsequent damage to the airplane 

caused by rapid opening of the door. 

DATES: We must receive comments on 

this proposed AD by October 14, 2005. 

ADDRESSES: Use one of the following 

addresses to submit comments on this 

proposed AD.

Discussion 

The DGAC, which is the 

airworthiness authority for France, 

notified us that an unsafe condition may 

exist on certain Airbus Model A300 B2 

series airplanes and A300 B4 series 

airplanes; Model A300 B4–600, B4–

600R, and F4–600R series airplanes, and 

Model C4 605R Variant F airplanes 

(collectively called A300–600); and 

Model A310 series airplanes. The DGAC 

advises that the existing cabin altitude 

pressure indicator can give a false 

indication of the cabin altitude 

especially when the pressurization 

system is operated in manual mode. 

Accidents have occurred on in-service 

airplanes when crewmembers forcibly 

initiated opening of passenger/crew 

doors against residual pressure (a 

positive pressure difference between 

inside the cabin and outside the cabin) 

causing the doors to rapidly open. In 

these accidents, the existing 

pressurization system did not indicate 

the presence of residual pressure in the 

cabin. 

Relevant Service Information 

Airbus has issued Service Bulletins 

A300–21–0131, Revision 01, dated 

January 6, 2005; A300–21–6050, 

Revision 01, dated December 17, 2004; 

and A310–21–2063, Revision 01, dated 

January 6, 2005. The service bulletins 

describe procedures for replacing the 

existing cabin altitude indicator in the 

cabin pressure control panel with a new 

improved cabin altitude indicator. The 

new cabin altitude indicator introduces 

a stop in the needle driving mechanism 

to limit the needle position near 5,000 

feet in case of extreme low altitude. (A 

stop already exists for the ‘‘overhigh’’

altitude.) The new cabin altitude 

indicator is designed to prevent false 

interpretation of the needle position 

when altitude goes out of the normal 

range. Accomplishing the actions 

specified in the service information is 

intended to adequately address the 

unsafe condition. The DGAC mandated 

the service information and issued 

French airworthiness directive F–2005–

027, dated February 16, 2005, to ensure 

the continued airworthiness of these 

airplanes in France. 

All three service bulletins described 

above reference Thales Service Bulletin 

37000–3–21–001, dated October 8, 2004, 

as an additional source of service 

information for replacing the cabin 

altitude indicator. 

FAA’s Determination and Requirements 

of the Proposed AD 

These airplane models are 

manufactured in France and are type 

certificated for operation in the United 

States under the provisions of section 

21.29 of the Federal Aviation 

Regulations (14 CFR 21.29) and the 

applicable bilateral airworthiness 

agreement. Pursuant to this bilateral 

airworthiness agreement, the DGAC has 

kept the FAA informed of the situation 

described above. We have examined the 

DGAC’s findings, evaluated all pertinent 

information, and determined that we 

need to issue an AD for products of this 

type design that are certificated for 

operation in the United States. 

Therefore, we are proposing this AD, 

which would require accomplishing the 

actions specified in the service 

information described previously. 

Costs of Compliance 

This proposed AD would affect about 

194 airplanes of U.S. registry. The 

proposed actions would take about 7 

work hours per airplane, at an average 

labor rate of $65 per work hour. 

Required parts would cost about $1,246 

per airplane. Based on these figures, the 

estimated cost of the proposed AD for 

U.S. operators is $329,994, or $1,701 per 

airplane. 

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 have 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 

Federal Register / Vol. 70, No. 177 / Wednesday, September 14, 2005 / Proposed Rules 54323 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that the 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); and 

3. 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. See the ADDRESSES

section for a location to examine the 

regulatory evaluation.

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–2005–22411; 

Directorate Identifier 2005–NM–074–AD. 

Comments Due Date 

(a) The Federal Aviation Administration 

must receive comments on this AD action by 

October 14, 2005. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Airbus Model A300

Unsafe Condition 

(d) This AD was prompted by a report of 

injuries occurring on in-service airplanes 

when crewmembers forcibly initiated 

opening of passenger/crew doors against 

residual pressure causing the doors to rapidly 

open. We are issuing this AD to prevent 

injury to crewmembers, and subsequent 

damage to the airplane caused by the rapid 

opening of the door. 

Compliance

date of this AD, replace the cabin altitude 

indicator (Part Number (P/N) 37000–3) in the 

cabin pressure control panel with a new 

improved cabin altitude indicator (P/N 

37000–3–01), in accordance with the service 

bulletins specified in Table 1 of this AD, as 

applicable.
