Airworthiness Directives; Boeing

Model 747 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment supersedes

an existing airworthiness directive (AD),

applicable to certain Boeing Model 747

series airplanes, that currently requires

disconnection of the electrical

connector to the scavenge pump of the

center wing tank. That AD also requires

a one-time inspection to identify the

part number of the electrical connector;

and replacement of the pump with a

new or serviceable pump, if necessary.

This amendment requires a one-time

inspection to identify the part number

of the scavenge pump motor-impeller

unit; and corrective action, if necessary.

This amendment is prompted by a

report of damage to the internal wiring

of a scavenge pump that had been

replaced in accordance with the existing

AD. The actions specified in this AD are

intended to prevent potential failures

within the electrical motor assembly of

the scavenge pump, which could result

in leakage of fuel from the electrical

connector into the main landing gear

wheel well, or electrical arcing within

the scavenge pump motor; these

conditions could result in a fuel fire in

the wheel well.

DATES: Effective July 23, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of July 23,

1998.

Comments for inclusion in the Rules

Docket must be received on or before

September 8, 1998.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), Transport

SUPPLEMENTARY INFORMATION: On

November 26, 1997, the FAA issued AD

97–25–06, amendment 39–10230 (62 FR

63622, December 1, 1997), applicable to

certain Boeing Model 747 series

airplanes. [A correction of the rule was

published in the Federal Register on

January 2, 1998 (63 FR 4).] That action

requires disconnection of the electrical

connector to the scavenge pump of the

center wing tank; a one-time inspection

to identify the part number of the

electrical connector; and replacement of

the pump with a new or serviceable

pump, if necessary. That action was

prompted by findings from a design

review and analysis of scavenge pumps

installed on certain Boeing Model 747

series airplanes that was undertaken as

part of an accident investigation. The

actions required by that AD are

intended to prevent potential failures

within the electrical motor assembly of

the scavenge pump, which could result

in leakage of fuel from the electrical

connector into the main landing gear

wheel well, or electrical arcing within

the scavenge pump motor; these

conditions could result in a fuel fire in

the wheel well.

Actions Since Issuance of Previous Rule

Since the issuance of that AD, the

FAA has received a report of damage to

the internal wiring of a scavenge pump;

the connector of that scavenge pump

had been replaced with a Lear Romecsupplied connector, in accordance with

the requirements of the existing AD. The

damage to the wiring has been

attributed to that replacement

connector’s longer backshell, which

provides insufficient clearance for the

attachment screw of the internal ground

wire of the scavenge pump motor, and

can cause interference between the

screw and the connector. Such wiring

damage, if not corrected, could cause

short circuiting and failures within the

electrical motor assembly; such failures

could result in leakage of fuel from the

electrical connector into the main

landing gear wheel well, or electrical

arcing within the scavenge pump motor,

and consequent fuel fire in the wheel

well.

Explanation of Relevant Service

Information

As a result of this recent finding,

Boeing has issued Alert Service Bulletin

747–28A2215, dated May 14, 1998,

which describes procedures for a onetime inspection to identify the part

number for the installed scavenge pump

motor-impeller unit; and corrective

action, if necessary. The alert service

bulletin provides operators a choice of

three corrective actions. First, operators

may replace the scavenge pump with a

different model scavenge pump.

Second, operators may replace the

scavenge pump with a scavenge pump

that has been modified in accordance

with Lear Romec Service Bulletin

RR24680 28–002, dated May 4, 1998.
Federal Register / Vol. 63, No. 130 /Wednesday, July 8, 1998 /Rules and Regulations 36837

(Lear Romec is the manufacturer of the

subject scavenge pump.) This

modification involves removal of the

connector ground jumper lead wire and

its attachment screw. Accomplishment

of the modification will provide

additional room for, and will prevent

short circuit damage to, the wires inside

the scavenge pump motor. Third,

operators may deactivate the scavenge

pump. The FAA has reviewed and

approved the Boeing and Lear Romec

service bulletins.

Explanation of Requirements of Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of this same

type design, this AD supersedes AD 97–

25–06 to require a one-time inspection

to identify the part number for the

installed scavenge pump motor-impeller

unit; and corrective action, if necessary.

Differences Between This AD and the

Relevant Service Information

This AD differs from Boeing Alert

Service Bulletin 747–28A2215, dated

May 14, 1998. The alert service bulletin

specifies that the scavenge pump may

be replaced with a scavenge pump

having ‘‘a different part number.’’

However, this AD specifically requires

that the replacement scavenge pump be

either a scavenge pump having part

number 60B92403–12, –13, or –18

(Intertechnique); or a scavenge pump

that has been modified in accordance

with Lear Romec Service Bulletin

RR24680 28–002, dated May 4, 1998.

Also, the Boeing alert service bulletin

specifies that a modified pump may be

reidentified as having one of two given

part numbers. However, this AD

requires that the pump modified in

accordance with Lear Romec Service

Bulletin RR24680 28–002 be

reidentified as Boeing P/N 60B92403–

51.

Determination of Rule’s Effective Date

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and

opportunity for prior public comment

hereon are impracticable, and that good

cause exists for making this amendment

effective in less than 30 days.

Comments Invited

Although this action is in the form of

a final rule that involves requirements

affecting flight safety and, thus, was not

preceded by notice and an opportunity

for public comment, comments are

invited on this rule. Interested persons

are invited to comment on this 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

under the caption ADDRESSES. All

communications received on or before

the closing date for comments will be

considered, and this rule may be

amended in light of the comments

received. Factual information that

supports the commenter’s ideas and

suggestions is extremely helpful in

evaluating the effectiveness of the AD

action and determining whether

additional rulemaking action would be

needed.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the 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 that

summarizes each FAA-public contact

concerned with the substance of this AD

will be filed in the Rules Docket.

Commenters wishing the FAA to

acknowledge receipt of their comments

submitted in response to this rule must

submit a self-addressed, stamped

postcard on which the following

statement is made: ‘‘Comments to

Docket Number 98–NM–145–AD.’’ The

postcard will be date stamped and

returned to the commenter.

Regulatory Impact

The regulations adopted herein will

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 final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

The FAA has determined that this

regulation is an emergency regulation

that must be issued immediately to

correct an unsafe condition in aircraft,

and that it is not a ‘‘significant

regulatory action’’ under Executive

Order 12866. It has been determined

further that this action involves an

emergency regulation under DOT

Regulatory Policies and Procedures (44

FR 11034, February 26, 1979). If it is

determined that this emergency

regulation otherwise would be

significant under DOT Regulatory

Policies and Procedures, a final

regulatory evaluation will be prepared

and placed in the Rules Docket. A copy

of it, if filed, may be obtained from the

Rules Docket at the location provided

under the caption ADDRESSES.

SUPPLEMENTARY INFORMATION: This

amendment to 14 CFR part 71 revises

the Class D airspace at San Antonio,

Kelly AFB, TX. The closure of Standard

Airport, San Antonio, TX, and the

relocation of the Kelly AFB TACAN

have made this rule necessary. The

intended effect of this action is to

provide adequate controlled airspace for

which is incorporated by reference in 14

CFR § 71.1. The Class D airspace

designation listed in this document will

be published subsequently in the order.

The Direct Final Rule Procedure

The FAA anticipates that this

regulation will not result in any adverse

or negative comment and therefore is

issuing it as a direct final rule. A

substantial number of previous

opportunities provided to the public to

comment on substantially identical

actions have resulted in negligible

adverse comments or objections. Unless

a written adverse or negative comment,

or a written notice of intent to submit

an adverse or negative comment, is

received within the comment period,

the regulation will become effective on

the date specified above. After the close

of the comment period, the FAA will

publish a document in the Federal

Register indicating that no adverse or

negative comments were received and

confirming the date on which the final

rule will become effective. If the FAA

does receive, within the comment

period, an adverse or negative comment

or written notice of intent to submit

such a comment, a document

withdrawing the direct final rule will be

published in the Federal Register, and

a notice of proposed rulemaking may be

published with a new comment period.

Comments Invited

Although this action is in the form of

a final rule and was not preceded by a

notice of proposed rulemaking,

comments are invited on this rule.

Interested persons are invited to

comment on this rule by submitting

such written data, views, or arguments

as they may desire. Communications

should identify the Rules Docket

number and be submitted in triplicate to

the address specified under the caption

ADDRESSES. All communications

received on or before the closing date

for comments will be considered, and

this rule may be amended or withdrawn

in light of the comments received.

Factual information that supports the

commenter’s ideas and suggestions is

extremely helpful in evaluating the

effectiveness of this action and

determining whether additional

rulemaking action is needed.

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the 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 that
