Propellers

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to MT-Propeller Entwicklung

GMBH Model MTV–3–B–C propellers.

This action requires initial and

repetitive dye penetrant or eddy current

inspections for cracks in the propeller

hub, and rework of the propeller hub or

replacement with a new model

propeller hub. This amendment is

prompted by reports of cracks in the

propeller flange area of the hub detected

during overhaul. The actions specified

in this AD are intended to prevent

propeller hub cracks, which could result

in propeller blade separation and

possible loss of control of the aircraft.

DATES: Effective October 22, 1997.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of October 22,

1997.

Comments for inclusion in the Rules

Docket must be received on or before

December 8, 1997.

SUPPLEMENTARY INFORMATION: The

Luftfahrt-Bundesamt (LBA), which is

the airworthiness authority for

Germany, recently notified the Federal

Aviation Administration (FAA) that an

unsafe condition may exist on MTPropeller Entwicklung GMBH Model

MTV–3–B–C/L250–21 propellers. The

LBA advises that they have received

reports of cracks in the propeller flange

area of the hub detected during

overhaul. The investigation revealed

that the cracks were created due to high

loads, such as those associated with

aerobatic maneuvers. This condition, if

not corrected, could result in propeller

hub cracks, which could result in

propeller blade separation and possible

loss of control of the aircraft.

MT-Propeller Entwicklung GMBH has

issued (SB) No. 12A, dated July 17,

1997, that specifies procedures for dye

penetrant or eddy current inspections

for cracks in the propeller hub, and, if

necessary, rework or replacement with

serviceable parts. The LBA classified

this SB as mandatory and issued AD 97–

006/2 in order to assure the

airworthiness of these propellers in

Germany.

This propeller model is manufactured

in Germany and is 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 LBA has kept the FAA informed of

the situation described above. The FAA

has examined the findings of the LBA,

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.

Since an unsafe condition has been

identified that is likely to exist or

develop on other propellers of the same

type design registered in the United

States, the AD will require initial and

repetitive dye penetrant or eddy current

inspections for cracks in the propeller

hub, and, if necessary, rework or

replacement with serviceable parts. The

actions would be required to be

accomplished in accordance with the

SB described previously.

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and

opportunity for prior public comment

hereon are impracticable, 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

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
52226 Federal Register / Vol. 62, No. 194 / Tuesday, October 7, 1997 / Rules and Regulations

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–36–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.
