NUCLEAR REGULATORY

COMMISSION

10 CFR Part 50

Environmental Qualification of Electric

Equipment

AGENCY: Nuclear Regulatory

Commission.

ACTION: Request for comment.

SUMMARY: The Commission has

undertaken a major initiative to answer

questions related to the environmental

qualification (EQ) of electric equipment

in nuclear power plants, 10 CFR 50.49.

In November 1993, the Office of Nuclear

Regulatory Research held a public

workshop to obtain technical input for

the formulation of EQ research program.

One of the recommendations made at

this workshop was that the NRC staff

should review all previous work in the

EQ area and endeavor to have its

research program cost effective without

duplicating past efforts.

The participants at the workshop

stated that the focus of the NRC’s

attention should be on components such

as cables and electrical penetrations,

that are long lived and very burdensome

to replace. The NRC staff accepted these

recommendations and the current

research efforts are limited to EQ issues

pertaining to cables. In this context, the

staff plans to review approximately 300

EQ documents (test reports, technical

papers and reports, etc.). The listing of

these references is available in the NRC

Public Document Room. The staff is

seeking public input to determine the

completeness of this list of references.

DATES: Submit additional references by

June 16, 1995.

DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. 95–NM–04–AD]

Airworthiness Directives; Airbus Model

A300 and A300–600 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 all

Airbus Model A300 and A300–600

series airplanes. This proposal would

require repetitive eddy current

inspections to detect cracks at the aft

spar web of the wings, and repair, if

necessary. This proposal is prompted by

reports indicating that cracks have been

found in the rear spar web of the wings

between ribs 1 and 2 of an in-service

airplane and during testing on the

fatigue test wing; the cracking occurred

due to fatigue-related high shear stress.

The actions specified by the proposed

AD are intended to prevent such fatiguerelated cracking, which could result in

reduced structural integrity of the wing.

DATES: Comments must be received by

June 13, 1995.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, ANM–103,

Attention: Rules Docket No. 95–NM–

04–AD, 1601 Lind Avenue SW., Renton,

Washington 98055–4056. Comments

may be inspected at this location

between 9:00 a.m. and 3:00 p.m.,

Monday through Friday, except Federal

holidays.

The service information referenced in

the proposed rule may be obtained from

Airbus Industrie, 1 Rond Point Maurice

Bellonte, 31707 Blagnac Cedex, France.

This information may be examined at

the FAA, Transport Airplane

Directorate, 1601 Lind Avenue SW.,

SUPPLEMENTARY INFORMATION:

Comments Invited

Interested persons are invited to

participate in the making of the

proposed rule by submitting such

written data, views, or arguments as

they may desire. Communications shall

identify the Rules Docket number and

be submitted in triplicate to the address

specified above. All communications

received on or before the closing date

for comments, specified above, will be

considered before taking action on the

proposed rule. The proposals contained

in this notice may be changed in light

of the comments received.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the proposed 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

summarizing each FAA-public contact

concerned with the substance of this

proposal 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

Discussion

The Direction Ge ́ne ́rale de l’Aviation

Civile (DGAC), which is the

airworthiness authority for France,

recently notified the FAA that an unsafe

condition may exist on all Airbus Model

A300 and A300–600 series airplanes.

The DGAC advises that cracks have

been found in the rear spar web of the

wings between ribs 1 and 2 of an inservice airplane and during testing of

the fatigue test wing. In both cases, the

cracks spanned across the tip of the

build slot and to the nearest adjacent

fastener hole. Investigation revealed that

such cracking was caused by fatiguerelated high shear stress experienced

during the landing cycle. Further

investigation revealed that the earliest

damage to an in-service airplane was

found on a Model A300–B2 series

airplane that had accumulated 21,500

flight cycles. The crack in the fatigue

test wing was discovered at 50,000

simulated flight cycles, and,

subsequently, was monitored for an

additional 12,000 flight cycles with no

evidence of continued crack growth

from the hole. Such fatigue-related

cracking, if not detected and corrected

in a timely manner, could result in

reduced structural integrity of the wing.

Airbus has issued Service Bulletin

A300–57–0213, dated August 12, 1994,

which is applicable to Model A300

series airplanes. This service bulletin

describes procedures for repetitive high

frequency eddy current (HFEC)

inspections to detect cracks at the aft

spar web of the wings, and repair, if

necesaary. The DGAC classified this

service bulletin as manadatory and

issued French airworthiness directive

94–207–168(B), dated September 14,

1994, in order to assure the continued

airworthiness of these airplanes in

France.

Airbus also has issued Service

Bulletin A300–57–6059, dated August

12, 1994, which is applicable to Model

A300–600 series airplanes. This service

bulletin describes procedures for

repetitive high frequency eddy current

(HFEC) inspections to detect cracks at

the aft spar web of the wings, and

repair, if necesaary. The DGAC plans to

make this service bulletin mandatory

when the Model A300–600 series

airplane fleet leader approaches the

accumulation of 21,600 total flight

cycles, which is the recommended time

for accomplishment of the initial

inspection.

This airplane model is manufactured

in France 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 DGAC has kept the FAA informed

of the situation described above. The

FAA has examined the findings of the

DGAC, 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
