(Military) Turboshaft Engines

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment revises an

existing airworthiness directive (AD),

applicable to AlliedSignal Inc. (formerly

Textron Lycoming) Model T5313B,

T5317A, and T53 series military

turboshaft engines approved for

installation on aircraft certified in

accordance with Section 21.25 of the

Federal Aviation Regulations (FAR),

that currently requires a one-time visual

inspection of accessory drive carrier

assemblies for affected serial numbers

(S/Ns) designating a defective assembly,

and if the S/N is applicable,

replacement with a serviceable

assembly. This amendment adds

military helicopter models and removes

one civilian helicopter model to the

sentence in the Applicability paragraph

of the AD that provides guidance as to

the helicopter models with the affected

engines. This amendment is prompted

by the need to revise the Applicability

paragraph. The actions specified by this

AD are intended to prevent accessory

drive carrier assembly failure, which

could result in an N2 overspeed and an

uncontained engine failure.

DATES: Effective July 6, 1998.

SUPPLEMENTARY INFORMATION: On

October 8, 1997, the Federal Aviation

Administration (FAA) issued AD 97–

21–07, Amendment 39–10160 (62 FR

53935, October 17, 1997), applicable to

AlliedSignal Inc. (formerly Textron

Lycoming) Model T5313B, T5317A, and

T53 series military turboshaft engines

approved for installation on aircraft

certified in accordance with Section

21.25 of the Federal Aviation

Regulations (FAR), to require a one-time

visual inspection of accessory drive

carrier assemblies for affected serial

numbers (S/Ns) designating a

potentially defective assembly, and if

the S/N is applicable, replacement with

a serviceable assembly. That action was

prompted by a report of an N2

overspeed condition on an AlliedSignal

Inc. Model T5317A–1 turboshaft engine.

That condition, if not corrected, could

result in accessory drive carrier

assembly failure, which could result in

an N2 overspeed and an uncontained

engine failure.

Since the issuance of that AD, the

FAA has been informed that the military

helicopter models that incorporate this

engine installation had been omitted

from the sentence in the Applicability

paragraph of the AD that provides

guidance as to the helicopter models

with the affected engines, and that a

civilian helicopter model, the Kaman

Aircraft Corp. K–1200 series helicopter,

should be removed from the list. The

military helicopter models, certified in

accordance with Section 21.25 of the

FAR, are: the UH–1A through E; UH–

1G, H, L, M; AH–1F, Q, G, S; HH–1H,

K; TH–1L; OV–1C, D; and HH–43. This

revised AD makes these changes to the

Applicability paragraph. All mandatory

actions required by the AD remain the

same.

The FAA has reviewed and approved

the technical contents of AlliedSignal

Inc. Alert Service Bulletin (ASB) No.

T5313B/17A–A0092, Revision 1, dated

July 1, 1997; ASB No. T53–L–13B–

A0092, dated June 4, 1997; and ASB No.

T53–L–703–A0092, dated June 4, 1997.

These ASBs describe procedures for

performing a one-time visual inspection

of accessory drive carrier assemblies for

affected S/Ns designating a defective

assembly, and if the S/N is applicable,

replacement with a serviceable

assembly.

Since an unsafe condition has been

identified that is likely to exist or

develop on other engines of this same

type design, this AD revises AD 97–21–

07 to add military helicopter models

and remove one civilian helicopter

model from the sentence in the

Applicability paragraph of the AD that

provides guidance as to the helicopter

models with the affected engines. The

actions are required to be accomplished

in accordance with the ASBs described

previously.

Since a situation exists that allows the

immediate adoption of this regulation, it

is found that notice and opportunity for

prior public comment hereon are

unnecessary, and that good cause exists

for making this amendment effective in

less than 30 days.

Comments Invited

Although this action is in the form of

a final rule that involves requirements

affecting flight safety and, thus, was not

preceded by notice and an opportunity
33540 Federal Register / Vol. 63, No. 118 / Friday, June 19, 1998 /Rules and Regulations

for public comment, comments are

invited on this rule. Interested persons

are invited to comment on this rule by

submitting such written data, views, or

arguments as they may desire.

Communications should identify the

Rules Docket number and be submitted

in triplicate to the address specified

under the caption ADDRESSES. All

communications received on or before

the closing date for comments will be

considered, and this rule may be

amended in light of the comments

received. Factual information that

supports the commenter’s ideas and

suggestions is extremely helpful in

evaluating the effectiveness of the AD

action and determining whether

additional rulemaking action would be

needed.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the rule. All comments

submitted will be available, both before

and after the closing date for comments,

in the Rules Docket for examination by

interested persons. A report that

summarizes each FAA-public contact

concerned with the substance of this AD

will be filed in the Rules Docket.

Commenters wishing the FAA to

acknowledge receipt of their comments

submitted in response to this notice

must submit a self-addressed, stamped

postcard on which the following

statement is made: ‘‘Comments to

Docket Number 97–ANE–38–AD.’’ The

postcard will be date stamped and

returned to the commenter.

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.

The FAA has determined that this

regulation is an emergency regulation

that must be issued immediately to

correct an unsafe condition in aircraft,

and is not a ‘‘significant regulatory

action’’ under Executive Order 12866. It

has been determined further that this

action involves an emergency regulation

under DOT Regulatory Policies and

Procedures (44 FR 11034, February 26,

1979). If it is determined that this

emergency regulation otherwise would

be significant under DOT Regulatory

Policies and Procedures, a final

regulatory evaluation will be prepared

and placed in the Rules Docket. A copy

of it, if filed, may be obtained from the

Rules Docket at the location provided

under the caption ADDRESSES.

AGENCY: Federal Aviation

Administration (FAA), DOT.

ACTION: Final rule.

SUMMARY: This amendment modifies

Class D airspace at MacDill AFB, FL.

The control tower at MacDill AFB is

now open 24 hours a day. Therefore, the

Class D airspace is amended from part

time to continuous.

EFFECTIVE DATE: 0901 UTC, August 13,

SUPPLEMENTARY INFORMATION:

History

On April 10, 1998, the FAA proposed

to amend part 71 of the Federal Aviation

Regulations (14 CFR part 71) by

amending Class D airspace at MacDill

AFB, FL (63 FR 17741). The control

tower at MacDill AFB is now open 24

hours a day. Therefore, the Class D

airspace was proposed to be amended

from part time to continuous. Class D

airspace designations are published in

Paragraph 5000 of FAA Order 7400.9E

dated September 10, 1997, and effective

September 16, 1997, which is

incorporated by reference in 14 CFR

part 71.1. The Class D airspace

designation listed in this document will

be published subsequently in the Order.

Interested parties were invited to

participate in this rulemaking

proceeding by submitting written

comments on the proposal to the FAA.

No comments objecting to the proposal

were received.

The Rule

This amendment to part 71 of the

Federal Aviation Regulations (14 CFR

part 71) modifies Class D airspace at

MacDill AFB, FL. The MacDill AFB

control tower is now open 24 hours a

day. Therefore, the Class D airspace is

amended from part time to continuous.

The FAA has determined that this

regulation only involves an established

body of technical regulations for which

frequent and routine amendments are

necessary to keep them operationally

current. It, therefore, (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)

does not warrant preparation of a

Regulatory Evaluation, as the

anticipated impact is so minimal. Since

this is a routine matter that will only

affect air traffic procedures and air

navigation, it is certified that this rule

will not have a significant economic

impact on a substantial number of small

entities under the criteria of the

Regulatory Flexibility Act.
