AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Kidde Aerospace P/N 898052 hand-held halon fire extinguishers that are utilized on aircraft. This proposed AD would require you to remove the affected fire extinguishers from service and would prevent you from using them in the future. This proposed AD is the result of information that shows that the discharge time of the affected fire extinguishers exceeds the maximum allowable discharge time. The problem is due to incomplete crimping of the siphon tube. The actions specified by this proposed AD are intended to remove from service fire extinguishers that had this incomplete crimping of the siphon tube. If not removed from service, these fire extinguishers could function at diminished levels and compromise the level of safety in an emergency situation.

DATES:

The Federal Aviation Administration (FAA) must receive any comments on this proposed rule on or before July 14, 2003.

ADDRESSES:

Submit comments to FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2003-CE-19-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. You may view any comments at this location between 8 a.m. and 4 p.m., Monday through Friday, except Federal holidays. You may also send comments electronically to the following address: 9-ACE-7-Docket@faa.gov. Comments sent electronically must contain “Docket No. 2003-CE-19-AD” in the subject line. If you send comments electronically as attached electronic files, the files must be formatted in Microsoft Word 97 for Windows or ASCII text.

You may get service information that applies to this proposed AD from Kidde Aerospace, Kidde Technologies, Inc., 4200 Airport Drive, NW., Wilson, North Carolina 27896; telephone: (252) 237-7004. You may also view this information at the Rules Docket at the address above.

Discussion

What Events Have Caused This Proposed AD?

The FAA has received information of problems with certain Kidde Aerospace P/N 898052 hand-held halon fire extinguishers that are utilized on aircraft. This information shows that the discharge time of the affected fire extinguishers exceeds the maximum allowable discharge time.

The problem is due to incomplete crimping of the siphon tube. Specifically, worn crimping tools were used to crimp the siphon tube. This is causing leakage between the siphon tube and the valve.

The fire extinguishers in question were manufactured from 1995 through 2002 and have a serial number of W-389653 or lower.

What Are the Consequences If the Condition Is Not Corrected?

If these fire extinguishers that had this incomplete crimping of the siphon tube are not removed from service, then the fire extinguishers could function at diminished levels and compromise the level of safety in an emergency situation.

Is There Service Information That Applies To This Subject?

Kidde Aerospace has issued Service Bulletin 898052-26-449, dated October 7, 2002.

What Are the Provisions of This Service Information?

The service bulletin describes the problem discussed in this proposed AD and includes procedures for identifying and returning the affected hand-held halon fire extinguishers.

The FAA's Determination and an Explanation of the Provisions of This Proposed AD

What Has FAA Decided?

After examining the circumstances and reviewing all available information Start Printed Page 25544related to the incidents described above, we have determined that:

—The unsafe condition referenced in this document exists or could develop on type design aircraft that utilize Kidde Aerospace P/N 898052 hand-held halon fire extinguishers that were manufactured from 1995 through 2002 and have a serial number of W-389653 or lower;

—The problem fire extinguishers should be removed from service; and

—AD action should be taken in order to correct this unsafe condition.

What Would This Proposed AD Require?

This proposed AD would require you to remove the affected fire extinguishers from service and would prevent you from using any affected fire extinguisher in the future.

How Does the Revision To 14 CFR Part 39 Affect This Proposed AD?

On July 10, 2002, FAA published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs FAA's AD system. This regulation now includes material that relates to special flight permits, alternative methods of compliance, and altered products. This material previously was included in each individual AD. Since this material is included in 14 CFR part 39, we will not include it in future AD actions.

Cost Impact

How Many Fire Extinguishers Would This Proposed AD Impact?

We estimate that this proposed AD could affect 38,695 fire extinguishers.

What Would Be the Cost Impact of This Proposed AD On Owners/Operators of the Affected Airplanes?

We estimate the following costs to remove the affected fire extinguishers from service (including replacing with another unit):

Labor costParts costTotal cost per airplane
2 workhours × $60 per hour = $120No cost for parts. Allow 5 days or more to ship the defective fire extinguishers to Kidde Aerospace$120.

Compliance Time of This Proposed AD

What Would Be the Compliance Time of This Proposed AD?

The compliance time of this proposed AD would be “within the next 6 months after the effective date of this AD.”

Why Is This Proposed Compliance Time Presented in Calendar Time Instead of Hours Time-in-Service (TIS)?

Although the slow discharge of the fire extinguishers is only a problem during flight, the unsafe condition is not a result of aircraft operation. Therefore, FAA has determined that a compliance based on calendar time should be utilized in this AD in order to ensure that the unsafe condition is addressed on all aircraft in a reasonable time period.

Regulatory Impact

Would This Proposed AD Impact Various Entities?

The regulations proposed herein would not have a substantial direct effect 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, it is determined that this proposed rule would not have federalism implications under Executive Order 13132.

Would This Proposed AD Involve a Significant Rule or Regulatory Action?

For the reasons discussed above, I certify that this proposed action (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. A copy of the draft regulatory evaluation prepared for this action has been placed in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
