7920 Federal Register / Vol. 60, No. 28 / Friday, February 10, 1995 / Proposed Rules

instrument air system in accordance

with the instructions provided with the

kits specified above.

The FAA estimates that 370 airplanes

in the U.S. registry would be affected by

the proposed AD, that it would take

approximately 30 workhours per

airplane to accomplish the proposed

action, and that the average labor rate is

approximately $60 an hour. The cost of

the applicable kit ranges from $505 to

$2,261 depending on the airplane

model. Based on these figures (using a

$2,261 part cost for all affected

airplanes), the total cost impact of the

proposed AD on U.S. operators is

estimated to be $1,502,570.

Beech will provide parts free of

charge until December 31, 1995. If all

owners/operators would incorporate

this modification by that date, then the

cost impact of the proposed AD upon

the public would be reduced by

$836,570 (370 airplanes × $2,261) from

$1,502,570 to $666,000.

In addition, Beech has informed the

FAA that it has distributed

approximately 18 kits. Assuming that

each of these distributed kits is

incorporated on one of the affected

airplanes and that each of the remaining

airplanes would have one of the kits

incorporated by December 31, 1995, the

cost of the proposed AD would be

further reduced by $32,400 (30

workhours × $60 × 18 airplanes) from

$666,000 to $633,600.

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 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) 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 has been placed in the Rules

Docket. A copy of it may be obtained by

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Supplemental notice of

proposed rulemaking (NPRM);

reopening of the comment period.

SUMMARY: This document proposes to

reopen the comment period of an earlier

proposed airworthiness directive (AD),

which would have proposed to require

modifying the shear fitting at the top of

each escape hatch on certain Jetstream

Aircraft Limited (JAL) Jetstream Models

3101 and 3201 airplanes. A report of

interference between the shear fitting on

an escape hatch and a ceiling panel

found while removing the escape hatch

on one of the affected airplanes

prompted the earlier proposal. Since

publication of that proposal, the Federal

Aviation Administration (FAA) has reexamined various service difficulty

reports on the affected airplanes, and
Federal Register / Vol. 60, No. 28 / Friday, February 10, 1995 / Proposed Rules 7921

determined that the proposed

modification is still a valid safety issue

(but not an urgent safety of flight issue).

Since sufficient time has passed (more

than 12 months) since the issuance of

the original proposal, the FAA is

allowing additional time for the public

to comment on this action. The

proposed actions are intended to

prevent the inability to utilize an escape

hatch during an emergency situation

because of interference.

DATES: Comments must be received on

or before April 14, 1995.

ADDRESSES: Submit comments in

triplicate to the FAA, Central Region,

Discussion

A proposal to amend part 39 of the

Federal Aviation Regulations (14 CFR

part 39) to include an AD that would

apply to certain JAL Jetstream Models

3101 and 3201 airplanes was published

in the Federal Register on March 30,

1992 (57 FR 10743). The action

proposed to require modifying the shear

fitting at the top of each escape hatch in

accordance with the

ACCOMPLISHMENT INSTRUCTIONS

section of Jetstream Service Bulletin 52–

JM 7752, dated December 17, 1991.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were received on the

proposed rule or the FAA’s

determination of the cost to the public.

Since publication of the proposal, the

FAA has re-examined various service

difficulty reports on the affected

airplanes, and determined that the

proposed modification is still a valid

safety issue, but is not considered an

urgent safety of flight issue. Since

sufficient time has passed (more than 12

months) since the issuance of the

original proposal, the FAA is reopening

the comment period to provide

additional time for public comment.

The FAA estimates that 120 airplanes

in the U.S. registry would be affected by

the proposed AD, that it would take

approximately 3 workhours per airplane

to accomplish the proposed action, and

that the average labor rate is

approximately $60 an hour. Rework of

existing parts would cost approximately

$165 per airplane. Based on these

figures, the total cost impact of the

proposed AD on U.S. operators is

estimated to be $41,400. This figure is

based on the assumption that no

affected owner/operator has

accomplished the proposed

modification. The FAA has no way of

determining how many airplanes have

incorporated this modification

(reworked the existing parts), but

anticipates that numerous operators

have already reworked the existing

parts. This would reduce the cost

impact of the proposed AD on U.S.

operators.

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 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) 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 has been placed in the Rules

Docket. A copy of it may be obtained by

7922 Federal Register / Vol. 60, No. 28 / Friday, February 10, 1995 / Proposed Rules

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding a new AD to read as follows:

Jetstream Aircraft Limited: Docket No. 92–

CE–13–AD.

Applicability: Jetstream Models 3101 and

3201 airplanes (serial numbers 757 through

912), certificated in any category.

Compliance: Required within the next 50

hours time-in-service after the effective date

of this AD, unless already accomplished.

To prevent occupant injury during an

emergency situation because of the inability

to remove an escape hatch, accomplish the

following:

(a) For both Models 3101 and 3201

airplanes, modify the shear fitting at the top

of the right-hand escape hatch in accordance

with PART A of the ACCOMPLISHMENT

INSTRUCTIONS section of Jetstream Service

Bulletin (SB) 52–JM 7752, dated December

17, 1991.

(b) For Model 3201 airplanes, modify the

shear fitting at the top of the left-hand escape

hatch in accordance with PART B of the

ACCOMPLISHMENT INSTRUCTIONS

section of Jetstream SB 52–JM 7752, dated

December 17, 1991.

(c) Special flight permits may be issued in

accordance with §§ 21.197 and 21.199 of the

Federal Aviation Regulations (14 CFR 21.197

reopening of the comment period.

SUMMARY: This document reopens the

comment period for an earlier proposed

airworthiness directive (AD) that

proposed to supersede AD 90–13–12,

which currently requires modifying the

airplane electrical system and revising

the emergency procedures section of the

Airplane Flight Manual (AFM) on

certain Jetstream Aircraft Limited (JAL)

Jetstream Models 3101 and 3201

airplanes. The proposal would have

retained the requirements of that AD for

those airplanes that have not installed

modified inverters and restored the

inverted transfer function. Since

publication of that proposal, the Federal

Aviation Administration (FAA) has reexamined various service difficulty

reports on the affected airplanes, and

determined that the proposed

modification is still a valid safety issue

(but not an urgent safety of flight issue).

Since sufficient time has passed (more

than 12 months) since the issuance of

the original proposal, the FAA is

allowing additional time for the public

to comment. The proposed actions are

intended to prevent alternating current

system failures, which, if not detected

and corrected, could result in damage to

the airplane navigational systems.

DATES: Comments must be received on

or before April 14, 1995.
