NUCLEAR REGULATORY

COMMISSION

10 CFR Part 50

Public Workshop on PerformanceBased Approach—Voluntary Option

AGENCY: Nuclear Regulatory

Commission.

ACTION: Notice of workshop.

SUMMARY: The Nuclear Regulatory

Commission (NRC) will host a public

workshop to solicit feedback on the

implementation of the direct final rule

for 10 CFR 50.54(a) and to gather

information to determine the need for

the development of the voluntary

alternative rulemaking based on Nuclear

Energy Institute petition PRM–50–62.

On February 23, 1999, the NRC

published a direct final rule in the

Federal Register (64 FR 9029), that

amended its regulations to permit power

reactor licensees to implement certain

quality assurance (QA) program changes

without obtaining prior NRC approval of

these changes. The direct final rule

became effective on April 26, 1999.

Based on the workshop outcome, the

staff will determine whether additional

rulemaking is warranted. The NRC

invites comments from interested

parties who are unable to attend the

workshop.

DATES: The workshop will be held on

Wednesday, June 7, 2000, from 9 a.m. to

12 p.m.

Commission, One White Flint North

[Docket No. 99–NM–163–AD]

RIN 2120–AA64

Airworthiness Directives; Boeing

Model 777 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

supersedure of an existing airworthiness

directive (AD), applicable to all Boeing

Model 777 series airplanes, that

currently requires repetitive testing of

the engine fire shutoff switch (EFSS) to

determine if the override mechanism

and the switch handle are operational,

and replacement of the EFSS, if

necessary. That AD also requires, for

certain airplanes, installation of a collar

on a specific circuit breaker of the

standby power management panel, and

installation of placards to advise the

flightcrew that the override mechanism

must be pushed in order to pull the fire

switch. That AD was prompted by a

report indicating that a solenoid and an

override mechanism of the EFSS were

not operational due to overheating of

the solenoid. The actions specified by

the proposed AD are intended to

prevent damage to the EFSS solenoid

and to the override mechanism, and

consequent failure of the EFSS due to

overheating of the solenoid; such failure

could result in the inability of the

flightcrew to discharge the fire

extinguishing agent in the event of an

engine fire. This action would add

various actions that would terminate the

repetitive testing requirements.

DATES: Comments must be received by

July 3, 2000.
