Airworthiness Directives; Dornier

Model 328–300 Series Airplanes

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 Dornier Model 328–300 series

airplanes. This proposal would require

replacement of the hydraulic line tube

assemblies with improved tube

assemblies and flexible hose assemblies.

This action is necessary to prevent

cracking of the hydraulic lines, which

could result in loss of hydraulic

pressure for certain braking systems on

the airplane. This action is intended to

address the identified unsafe condition.

DATES: Comments must be received by

July 17, 2000.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, ANM–114,

Attention: Rules Docket No. 2000–NM–

Comments may be inspected at this

location between 9:00 a.m. and 3:00

p.m., Monday through Friday, except

Federal holidays. Comments may also

be sent via the Internet using the

Discussion

The Luftfahrt-Bundesamt (LBA),

which is the airworthiness authority for

Germany, notified the FAA that an

unsafe condition may exist on certain

Dornier Model 328–300 series airplanes.

The LBA advises that pressure spikes

and vibration during manual activation

of the hydraulic changeover valve may

cause cracking of the hydraulic lines

that pressurize the braking systems of

these airplanes. The pressure spikes

create a high bending stress near the

sleeve at the changeover valve. Such

cracking of the hydraulic lines, if not

corrected, could result in loss of

hydraulic pressure for certain braking

systems on the airplane.

Explanation of Relevant Service

Information

Dornier has issued Alert Service

Bulletin ASB–328J–32–003 (including

Annex 1), dated December 17, 1999. The

alert service bulletin describes

procedures for replacement of the

hydraulic line tube assemblies with

improved tube assemblies and flexible

hose assemblies. 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 2000–050, dated

February 24, 2000, 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

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

Federal Register / Vol. 65, No. 116 / Thursday, June 15, 2000 / Proposed Rules 37501

accomplishment of the actions specified

in the service bulletin described

previously.

Cost Impact

The FAA estimates that 9 airplanes of

U.S. registry would be affected by this

proposed AD, that it would take

approximately 5 work hours per

airplane to accomplish the proposed

replacement, and that the average labor

rate is $60 per work hour. Required

parts would be provided free of charge

by the manufacturer. Based on these

figures, the cost impact of the proposed

AD on U.S. operators is estimated to be

$2,700, or $300 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 a substantial direct

effect 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,

it is determined that this proposal

would not have federalism implications

under Executive Order 13132.

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

The Proposed Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration proposes to amend part

39 of the Federal Aviation Regulations

(14 CFR part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

Dornier Luftfahrt GMBH: Docket 2000–NM–

07–AD.

Applicability: Model 328–300 series

airplanes, serial numbers 3108 through 3144

inclusive; certificated in any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

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 (b) 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 cracking of the hydraulic lines,

which could result in loss of hydraulic

pressure for certain braking systems on the

airplane, accomplish the following:

Replacement

(a) Within 30 days after the effective date

of this AD, replace the hydraulic line tube

assemblies with new, improved tube

assemblies and flexible hose assemblies; in

accordance with Dornier Alert Service

Bulletin ASB–328J–32–003 (including Annex

1), dated December 17, 1999.

Alternative Methods of Compliance

(b) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager,

International Branch, ANM–116, FAA,

Transport Airplane Directorate. Operators

shall submit their requests through an

appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, International Branch,

ANM–116.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the International Branch,

ANM–116.

Special Flight Permits

(c) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the airplane to

a location where the requirements of this AD

can be accomplished.

Note 3: The subject of this AD is addressed

in German airworthiness directive 2000–050,

dated February 24, 2000.

SUPPLEMENTARY INFORMATION:

Background

Section 2406(a) of the Miscellaneous

Trade and Technical Corrections Act of

1999 (the Act, Public Law 106–36, 113

Stat. 127) amended the Tariff Act of

1930 by the addition of a new section

484b (19 U.S.C. 1484b). Section 484b

provides that an otherwise dutiable

‘‘large yacht’’ (defined in the section as

‘‘a vessel that exceeds 79 feet in length,

is used primarily for recreation or

pleasure, and has been previously sold

by a manufacturer or dealer to a retail

consumer’’) may be imported without

the payment of duty if the yacht is
