Cartridges

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to certain Pacific Scientific

Company, HTL/Kin-Tech Division, fire

extinguisher bottle cartridges (squibs),

which may be installed on various

transport category airplanes. This action

requires a one-time inspection of the

electrical receptacle of these fire

extinguisher bottle cartridges and their

mating connectors to detect the

presence of aluminum foil in the area of

the pins of the cartridges and the

connectors, and removal of any

aluminum foil that is present. This

amendment is prompted by a report of

failure of a fire extinguisher bottle

cartridge to discharge as a result of the

presence of aluminum foil in the

cartridge, which caused electrical

shorting of the pins. The actions

specified in this AD are intended to

prevent such shorting, which could

result in failure of the fire extinguisher

bottle to discharge when commanded.

DATES: Effective March 7, 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), Transport

Airplane Directorate, ANM–103,

Attention: Rules Docket No. 97–NM–

27–AD, 1601 Lind Avenue, SW.,

SUPPLEMENTARY INFORMATION: The FAA

received a report indicating that a

Pacific Scientific Company, HTL/KinTech Division, fire extinguisher bottle

cartridge (squib) failed to discharge

when commanded. Investigation

revealed that aluminum foil was present

in the cartridge, which caused electrical

shorting of the pins. Aluminum foil is

used to shunt the electrical pins of the

cartridge for shipping purposes. The

aluminum foil had not been removed

properly prior to installation of the fire

extinguisher bottle cartridge. Further

investigation revealed that the electrical

shorting condition existed on six other

installed cartridges.

The affected cartridges are Pacific

Scientific Company, HTL/Kin-Tech

Division, fire extinguisher bottle

cartridges having part numbers 13083–

10 and 13083–25.

Electrical shorting of the pins in the

fire extinguisher bottle cartridges, if not

corrected, could result in failure of the

fire extinguisher bottle to discharge

when commanded.

FAA’s Determination

The FAA has determined that, in

order to ensure that the fire extinguisher

bottle will discharge when commanded,

Pacific Scientific Company, HTL/KinTech Division, fire extinguisher bottle

cartridges having part numbers 13083–

10 and 13083–25 must be inspected to

ensure that any aluminum foil is

removed from the fire extinguisher

bottle cartridges installed on the

affected airplanes.

Explanation of the Requirements of the

Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other components of the

same type design installed on transport

category airplanes, this AD is being

issued to prevent electrical shorting of

the pins of the fire extinguisher bottle

cartridge, which could result in failure

of the fire extinguisher bottle to

discharge when commanded. This AD

requires a one-time visual inspection of

the electrical receptacle of certain

Pacific Scientific Company, HTL/KinTech Division, fire extinguisher bottle

cartridges and their mating connectors

to detect the presence of aluminum foil

in the area of the pins of the cartridges

and the connectors, and removal of any

aluminum foil that is present.

Determination of Rule’s Effective Date

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and
7670 Federal Register / Vol. 62, No. 34 / Thursday, February 20, 1997 / Rules and Regulations

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 97–NM–27–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.
