AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to Auxiliary Power

International Corporation (APIC) Model

APS3200 Auxiliary Power Units (APUs).

This action requires replacement of the

existing Electronic Control Box (ECB),

incorporating its On Board Replaceable

Module (OBRM) programmed with

originally approved software version

2.0.2 or 3.2 with improved software

version 4.1, or replacement of the

existing OBRM of the ECB programmed

with version 2.0.2 or version 3.2 with a

new OBRM programmed with software

version 4.1. This amendment is

prompted by reports of continued fuel

flow to the APU after the APU was

commanded to shutdown, resulting in

internal APU fires. The actions specified

in this AD are intended to prevent

internal APU fires due to ECB

malfunction, which, if left unnoticed by

flight or ground crews, could result in

damage to the aircraft.

DATES: Effective March 6, 1997.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of March 6,

1997.

Comments for inclusion in the Rules

Docket must be received on or before

April 21, 1997.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), New England

Region, Office of the Assistant Chief

Counsel, Attention: Rules Docket No.

SUPPLEMENTARY INFORMATION: The

Federal Aviation Administration (FAA)

has received reports of four Auxiliary

Power Units (APU) internal fires after

shutdown of Auxiliary Power

International Corporation (APIC) Model

APS3200 APUs. The investigations

revealed two possible causes of these

fires: first, in three of the events, a

software deficiency in the Electronic

Control Box (ECB) allowed the APU fuel

shut-off valve to remain open; second,

in one unconfirmed event, possible fuel

system contamination could have kept

the valve from closing completely. This

AD addresses the ECB software

deficiency only. It does not address

valve malfunction caused by fuel system

contamination.

These ECB malfunctions may result in

an internal fire within the APU, in the

APU plenum, air intake, and possibly in

the tail of the aircraft. This condition, if

not corrected, could result in an internal

APU fire due to ECB malfunction,

which, if left unnoticed by flight or

ground crews, could result in damage to

the aircraft.

The FAA has reviewed and approved

the technical contents of APIC Service

Bulletin (SB) No. 4500001–49–52, dated

October 1, 1996, that describes

procedures for replacement of the

existing On Board Replaceable Module

(OBRM) of the ECB incorporating the

software versions 2.0.2 or 3.2 with a

new OBRM programmed with software

version 4.1. This software also

commands closing of the aircraft APU

firewall fuel shut-off valve in addition

to the APU fuel shut-off valve during

APU shutdowns.

Since an unsafe condition has been

identified that is likely to exist or

develop on other APUs of the same type

design, this AD is being issued to

prevent an APU fire due to ECB

malfunction, which could result in

damage to the aircraft. This AD requires

replacement of the existing APU ECB

(incorporating the originally approved

software versions 2.0.2 or 3.2) with

improved software version. 4.1, or

installation of an OBRM programmed

with software version 4.1 in the ECB

prior to 30 days after the effective date

of this AD. This calendar end-date is

based on parts availability. The actions

are required to be accomplished in

accordance with the SB described

previously.

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 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 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
7344 Federal Register / Vol. 62, No. 33 / Wednesday, February 19, 1997 / Rules and Regulations

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 notice

must submit a self-addressed, stamped

postcard on which the following

statement is made: ‘‘Comments to

Docket Number 96-ANE–42.’’ The

postcard will be date stamped and

returned to the commenter.

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 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.
