39–9157; AD 95–04–05]

Airworthiness Directives; Bombardier

(Formerly Canadair) Model CL–600–

2B19 (Regional Jet Series 100) Series

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Bombardier Model

CL–600–2B19 (Regional Jet Series 100)

series airplanes, that requires various

modifications of the passenger doors.

This amendment is prompted by reports

that some passenger doors froze shut

during flight and could not be opened

after landing the airplane. The actions

specified by this AD are intended to

prevent the passenger doors from

freezing shut, and consequently,

prohibiting the passengers from exiting

the airplane in the event of an

emergency.

DATES: Effective April 7, 1995.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of April 7,

1995.

ADDRESSES: The service information

referenced in this AD may be obtained

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to certain Bombardier

Model CL–600–2B19 (Regional Jet

Series 100) series airplanes was

published in the Federal Register on

October 28, 1994 (59 FR 54136). That

action proposed to require various

modifications of the passenger doors.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the proposal or the FAA’s

determination of the cost to the public.

The final rule has been revised to

reflect the manufacturer’s corporate

name change from Canadair to

‘‘Bombardier, Inc.’’

Additionally, as a result of recent

communications with the Air Transport

Association (ATA) of America, the FAA

has learned that, in general, some

operators may misunderstand the legal

effect of AD’s on airplanes that are

identified in the applicability provision

of the AD, but that have been altered or

repaired in the area addressed by the

AD. The FAA points out that all

airplanes identified in the applicability

provision of an AD are legally subject to

the AD. If an airplane has been altered

or repaired in the affected area in such

a way as to affect compliance with the

AD, the owner or operator is required to

obtain FAA approval for an alternative

method of compliance with the AD, in

accordance with the paragraph of each

AD that provides for such approvals. A

note has been added to this final rule to

clarify this long-standing requirement.

After careful review of the available

data the FAA has determined that air

safety and the public interest require the

adoption of the rule with the changes

previously described. The FAA has

determined that these changes will

neither increase the economic burden

on any operator nor increase the scope

of the AD.

The FAA estimates that 17 airplanes

of U.S. registry will be affected by this

AD, that it will take approximately 67

work hours per airplane to accomplish

the required actions, and that the

average labor rate is $60 per work hour.

Required parts will cost approximately

$10,945 per airplane. Based on these

figures, the total cost impact of the AD

on U.S. operators is estimated to be

$254,405, or $14,965 per airplane.

The total cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the requirements of this AD action, and

that no operator would accomplish

those actions in the future if this AD

were not adopted. The regulations adopted herein will

not have substantial direct effects 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. Therefore, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

For the reasons discussed above, I

certify that this action (1) is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a

‘‘significant rule’’ under 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. A final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

Adoption of the Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration amends part 39 of the

Federal Aviation Regulations (14 CFR

part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 U.S.C. App. 1354(a), 1421

and 1423; 49 U.S.C. 106(g); and 14 CFR

11.89.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

94–NM–97–AD.

Applicability: Model CL–600–2B19

serial numbers 7003 and subsequent,

certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been
Federal Register / Vol. 60, No. 45 / Wednesday, March 8, 1995 / Rules and Regulations 12667

modified, altered, or repaired in the area

subject to the requirements of this AD. For

airplanes that have been modified, altered, or

repaired so that the performance of the

requirements of this AD is affected, the

owner/operator must use the authority

provided in paragraph (h) to request approval

from the FAA. This approval may address

either no action, if the current configuration

eliminates the unsafe condition; or different

actions necessary to address the unsafe

condition described in this AD. Such a

request should include an assessment of the

effect of the changed configuration on the

unsafe condition addressed by this AD. In no

case does the presence of any modification,

alteration, or repair remove any airplane from

the applicability of this AD.

Compliance: Required as indicated, unless

accomplished previously.

To prevent the inability of passengers to

exit the airplane in the event of an

emergency, accomplish the following:
