Discussion

The Luftfahrt-Bundesamt (LBA),

which is the airworthiness authority for

Germany, notified the FAA that an

unsafe condition may exist on certain

Dornier 328–100 series airplanes. The

LBA advises that, during a failed startup

of an engine, the flight crew detected a

smell of burned cables. This failure was

attributed to loose electrical connections

in the passenger cabin, which caused an

increase in the electrical resistance. This

condition, if not corrected, could result

in overheating at the electrical terminals

and consequent smoke/fire in the

airplane passenger cabin.

Explanation of Relevant Service

Information

Dornier has issued Service Bulletin

SB–328–24–188, dated September 11,

1996, which describes procedures for

replacement of certain electrical

terminals in the passenger cabin with

new electrical terminals.

Accomplishment of the actions

specified in the service bulletin is

intended to adequately address the

identified unsafe condition. The LBA

classified this service bulletin as

mandatory and issued German

airworthiness directive 96–291, dated

November 7, 1996, in order to assure the

continued airworthiness of these

airplanes in Germany.

FAA’s Conclusions

This airplane 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
Federal Register / Vol. 62, No. 216 / Friday, November 7, 1997 / Proposed Rules 60189

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.

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 registered in the United

States, the proposed AD would require

accomplishment of the actions specified

in the service bulletin described

previously.

Cost Impact

The FAA estimates that 7 Dornier

Model 328–100 series airplanes of U.S.

registry would be affected by this

proposed AD, that it would take

approximately 2 work hours per

airplane to accomplish the proposed

actions, and that the average labor rate

is $60 per work hour. Required parts

would be provided by the manufacturer

at no cost to operators. Based on these

figures, the cost impact of the proposed

AD on U.S. operators is estimated to be

$840, or $120 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

contacting the Rules Docket at the

location provided under the caption

provision, regardless of whether it has been

otherwise 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 request approval for an

alternative method of compliance in

accordance with paragraph (c) of this AD.

The request should include an assessment of

the effect of the modification, alteration, or

repair on the unsafe condition addressed by

this AD; and, if the unsafe condition has not

been eliminated, the request should include

specific proposed actions to address it.

Compliance: Required as indicated, unless

accomplished previously.

To prevent loose electrical connections

from causing an increase in electrical

resistance, which could result in overheating

at the electrical terminals and consequent

smoke/fire in the airplane passenger cabin,

accomplish the following:

(a) Within 100 flight hours after the

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes to

adopt a new airworthiness directive

(AD) that would apply to certain

SOCATA—Groupe AEROSPATIALE

(Socata) Models TB9, TB10, TB20,

TB21, and TB200 airplanes. The

proposed AD would require inspecting

the bolts and spacers of the upper

attachments of the front belts for cracks,

dents, etc. (damage); replacing any

damaged bolts or spacers; incorporating

a front belts upper attachment

reinforcement kit; and reconditioning

the belts. The proposed AD is the result

of mandatory continuing airworthiness

information (MCAI) issued by the

airworthiness authority for France. The

actions specified by the proposed AD

are intended to prevent failure of the

upper seat belt attachment caused by

excessive loads on the upper attachment

of the belt, which could result in bodily

injury to the occupants during landing.

DATES: Comments must be received on

or before December 15, 1997.
