AD.

Not Applicable.

(e) Can I comply with this AD in any other

way? You may use an alternative method of

compliance or adjust the compliance time if:

(1) Your alternative method of compliance

provides an equivalent level of safety; and

(2) The Manager, Wichita Aircraft

Certification Office (ACO), approves your

alternative. Submit your request through an

Note: This AD applies to each airplane

identified in paragraph (a) of this AD,

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 (e)

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 you have not

eliminated the unsafe condition, specific

actions you propose to address it.

Airworthiness Directives; McDonnell

Douglas Model MD–90–30 Series

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; correction.

SUMMARY: This document supersedes an

existing airworthiness directive (AD)

that applies to certain McDonnell

Douglas Model MD–90–30 series

airplanes. That AD currently requires

replacement of certain ground block

screws with new screws; and

retermination of the circuit ground

wires of the electrical power control

unit (EPCU) to separate grounding

points. The actions specified in that AD

are intended to prevent a loose electrical

ground block of the circuit ground wires

of the EPCU, which could result in

complete loss of the primary electrical

power of an airplane during flight. This

amendment is prompted by the Federal

Aviation Administration’s

determination that the existing AD must

be revised to ensure that the

requirements apply to the appropriate

airplane groups.

DATES: Effective November 13, 2000.

The incorporation by reference of

McDonnell Douglas Service Bulletin

MD90–24–062, dated February 3, 2000,

as listed in the regulations, is approved

by the Director of the Federal Register

as of November 13, 2000.

The incorporation by reference of

McDonnell Douglas Alert Service

Bulletin MD90–24A060, Revision 01,

dated September 2, 1999, as listed in the

regulations, was approved previously by

the Director of the Federal Register as of

September 19, 2000 (65 FR 49728,

August 15, 2000).

SUPPLEMENTARY INFORMATION: On August

3, 2000, the Federal Aviation

Administration (FAA) issued AD 2000–

16–01, amendment 39–11855 (65 FR

49728, August 15, 2000), which applies

to certain McDonnell Douglas Model

MD–90–30 series airplanes. That AD

requires replacement of certain ground

block screws with new screws; and

retermination of the circuit ground

wires of the electrical power control

unit (EPCU) to separate grounding

points. That AD was prompted by

reports of complete loss of the primary

electrical power on an airplane during

flight. The actions required by that AD

are intended to prevent a loose electrical

ground block of the circuit ground wires

of the EPCU, which could result in

complete loss of the primary electrical

power of an airplane during flight.

Need for the Correction

In the preamble of AD 2000–16–01,

the FAA indicated that a supplemental

notice of proposed rulemaking (NPRM)

was published in the Federal Register

on June 12, 2000 (65 FR 36799). After

careful review of the available data,

including the comments received from

the public, the FAA determined that air

safety and the public interest required

the adoption of the rule as proposed in

the supplemental NPRM. However, the

FAA inadvertently included the

requirements from the original NPRM

(64 FR 68302, December 7, 1999) in the

final rule, rather than the requirements

specified in paragraphs (a) and (b) of the

supplemental NPRM. The effect of this

error is that operators of certain

airplanes are not required to accomplish

actions that apply to those airplanes,

59708 Federal Register / Vol. 65, No. 195 / Friday, October 6, 2000 / Rules and Regulations

and that certain actions are to be

accomplished in accordance with a

method approved by the FAA, rather

than a specific service bulletin.

Therefore, consistent with the FAA’s

intent in the supplemental NPRM, this

correction is necessary to require

operators of specific airplanes to replace

certain ground block screws with new

screws and to reterminate the circuit

ground wires of the EPCU to separate

grounding points.

These actions shall be done in

accordance with McDonnell Douglas

Alert Service Bulletin MD90–24A060,

Revision 01, dated September 2, 1999;

and McDonnell Douglas Service

Bulletin MD90–24–062, dated February

3, 2000; as applicable. The FAA

inadventently omitted McDonnell

Douglas Service Bulletin MD90–24–062

from the incorporation by reference

paragraph and is incorporating by

reference that service bulletin in this

final rule.

Correction of Publication

Action is taken herein to correct these

inadvertent errors in AD 2000–16–01

and to correctly add this AD as an

amendment to section 39.13 of the

Federal Aviation Regulations (14 CFR

39.13). The AD is reprinted in its

entirety for the convenience of affected

operators.

Since this action only corrects current

requirements, it has no adverse

economic impact and imposes no

additional burden on any person.

Therefore, the FAA has determined that

notice and public procedures are

unnecessary.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation

safety, Incorporation by reference,

Safety.

Adoption of the Correction

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration amends part 39 of the

Federal Aviation Regulations (14 CFR

24–062, dated February 3, 2000; 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 (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 a loose electrical ground block

of the circuit ground wires of the electrical

power control unit (EPCU), accomplish the

following:

Replacement

(a) For airplanes listed in McDonnell

Douglas Alert Service Bulletin MD90–

24A060, Revision 01, dated September 2,

Note 2: Accomplishment of the

replacement of electrical ground block

screws prior to the effective date of this AD

in accordance with McDonnell Douglas Alert

2000.

Alternative Methods of Compliance

(c) 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, Los

Angeles Aircraft Certification Office (ACO),

FAA. Operators shall submit their requests

through an appropriate FAA Principal

Maintenance Inspector, who may add

comments and then send it to the Manager,
