AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) that is applicable to

certain Bombardier Model CL–600–

2B16 and CL–600–2B19 series airplanes.

This proposal would require a one-time

inspection of the spring bungee

assembly of the nose landing gear (NLG)

to ensure proper torque of the collar and

correct clearance between the collar and

the body of the bungee, and replacement

of the spring bungee assembly with a

serviceable unit, if necessary. This

proposal is prompted by reports of

failure of the NLG to extend when the

landing gear selector was placed in the

‘‘DOWN’’ position, and failure of the

NLG doors to open when the NLG door

switch was set in the ‘‘SAFETY/DOOR

OPEN’’ position; these conditions may

have been caused by a reduced stroke of

the spring bungee. The actions specified

by the proposed AD are intended to

prevent improper operation of the NLG

door and consequent inability to extend

the NLG due to a reduced stroke of the

spring bungee.

DATES: Comments must be received by

August 16, 1996.

Discussion

Transport Canada Aviation, which is

the airworthiness authority for Canada,

recently notified the FAA that an unsafe

condition may exist on certain

Bombardier Model CL–600–2B16 (CL–

601–3A and –3R), and CL–600–2B19

(Regional Jet Series 100) series

airplanes. Transport Canada Aviation

advises that it received reports

indicating that, during flight of a Model

CL–600–2B19 series airplane, the nose

landing gear (NLG) did not extend when

the landing gear selector was placed in

the ‘‘DOWN’’ position. The NLG did

extend following cycling of the selector

valve. Transport Canada Aviation also

advises that it received a report

indicating that, during a pre-flight check

of a Model CL–600–2B16 series

airplane, the NLG doors did not open

when the NLG door switch was set in

the ‘‘SAFETY/DOOR OPEN’’ position.

The cause of these occurrences has been

attributed to a defective spring bungee

assembly of the NLG door mechanism.

Investigation revealed that the spring
35692 Federal Register / Vol. 61, No. 131 / Monday, July 8, 1996 / Proposed Rules

bungee may have a reduced stroke due

to incorrect clearance between the collar

and the body of the spring bungee. This

incorrect clearance was the result of

incorrect assembly during manufacture.

This condition, if not corrected, could

result in improper operation of the NLG

door, which could result in inability to

extend the NLG.

Explanation of Relevant Service

Information

The manufacturer has issued Canadair

Regional Jet Alert Service Bulletin

A601R–32–037, Revision ‘‘A,’’ dated

December 2, 1994 (for Model CL–600–

2B19 series airplanes), and Canadair

Challenger Service Bulletin 601–0454,

dated May 15, 1995, as amended by

Service Bulletin Information Sheet 601–

0454, dated July 14, 1995 (for Model

CL–600–2B16 series airplanes). These

service bulletins describe procedures for

a one-time inspection of the spring

bungee assembly of the NLG to ensure

proper torque of the collar and correct

clearance between the collar and the

body of the bungee, and replacement of

the spring bungee assembly with a

serviceable (new or reworked) unit, if

necessary. Transport Canada Aviation

classified these service bulletins as

mandatory and issued Canadian

airworthiness directive CF–95–10, dated

June 27, 1995, in order to assure the

continued airworthiness of these

airplanes in Canada.

FAA’s Conclusions

These airplane models are

manufactured in Canada 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, Transport

Canada Aviation has kept the FAA

informed of the situation described

above. The FAA has examined the

findings of Transport Canada Aviation,

reviewed all available information, and

determined that AD action is necessary

for products of this type design that are

certificated for operation in the United

States.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design, the proposed AD would

require a one-time inspection of the

spring bungee assembly of the NLG to

ensure proper torque of the collar and

correct clearance between the collar and

the body of the bungee, and replacement

of the spring bungee assembly with a

serviceable (new or reworked) unit, if

necessary. The actions would be

required to be accomplished in

accordance with the service bulletins

described previously.

Explanation of Differences between

Service Bulletins and the Proposed

Rule

Operators should note that the

compliance time specified in this

proposed AD (within 90 days after the

effective date of the AD) differs from the

times recommended in the referenced

service bulletins. [The compliance time

recommended in Canadair Challenger

Service Bulletin 601–0454 for Model

CL–600–2B16 series airplanes is ‘‘at the

next 300-hour check.’’ Canadair

Regional Jet Alert Service Bulletin

A601R–32–037 (for Model CL–600–

2B19 series airplanes) recommends a

compliance time of no later than the

next ‘‘A’’ check or within the next three

months after receipt of the alert service

bulletin.] The FAA finds that the

compliance time should not differ for

each airplane model, since the spring

bungee installed on both models has the

same part number. In developing an

appropriate compliance time for this

AD, the FAA also considered not only

the degree of urgency associated with

addressing the subject unsafe condition,

but availability of replacement parts and

the maximum interval of time allowable

for all affected airplanes to continue to

operate without compromising safety.

The FAA finds 90 days to be an

appropriate compliance time for

accomplishing these actions.

Cost Impact

The FAA estimates that 101 airplanes

of U.S. registry would be affected by this

proposed AD, that it would take

approximately 4 work hours per

airplane to accomplish the proposed

actions, and that the average labor rate

is $60 per work hour. Based on these

figures, the cost impact of the proposed

AD on U.S. operators is estimated to be

$24,240, or $240 per airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the proposed requirements of this AD

action, and that no operator would

accomplish those actions in the future if

this AD were not adopted.

Regulatory Impact

The regulations proposed herein

would 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

proposal would not have sufficient

federalism implications to warrant the

preparation of a Federalism Assessment.

For the reasons discussed above, I

certify that 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); and (3) if

promulgated, 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 copy of the draft

regulatory evaluation prepared for this

action is contained in the Rules Docket.

A copy of it may be obtained by

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes to

adopt a new airworthiness directive

(AD) that would apply to Aerospace

Technologies of Australia Pty Ltd.

(ASTA) Models N22B, N24A, and N22S

airplanes that are not equipped with a

part number (P/N) 1E/N–12–57 fuselage

stub fin plate (MOD N759). The

proposed action would require

replacing the existing fuselage stub fin

plate with one of improved design, P/N

1E/N–12–57. Several reports of cracks

along the forward flange of the fuselage

stub fin plate in the area of Rib Water

Line (WL) 138.87 prompted the

proposed action. The actions specified

by the proposed AD are intended to

prevent structural failure of the fuselage

area caused by a cracked stub fin plate,

which, if not detected and corrected,

could result in loss of control of the

airplane.
