Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

The FAA adopts an airworthiness directive (AD) to supersede AD 2003-11-14, which applies to certain The New Piper Aircraft, Inc. (Piper) Models PA-34-200T, PA-34-220T, PA-44-180, and PA-44-180T airplanes that have a model 91E92-1 or model 91E93-1 combustion heater fuel pump installed. AD 2003-11-14 currently requires you to do a one-time inspection of the combustion heater fuel pumps for fuel leakage. If leakage is found, repair or replace the fuel pump. This AD retains all the actions of AD 2003-11-14 and includes additional serial numbers for the Models PA-34-220T and PA-44-180 airplanes in the applicability section. This AD results from an investigation that concluded that after Start Printed Page 43030the issuance of AD 2003-11-14, additional fuel pumps that did not meet the quality control (inspection or design) requirements of the AD had been installed in Models PA-34-220T and PA-44-180 airplanes. We are issuing this AD to correct quality control problems with the heater fuel pump, which could result in failure of the heater fuel pump. Such failure could lead to fire or explosion in the cockpit.

DATES:

This AD becomes effective on August 26, 2005.

On June 20, 2003 (68 FR 33356, June 4, 2003), the Director of the Federal Register approved the incorporation by reference of The New Piper Aircraft, Inc. Service Bulletin No. 1127, dated February 26, 2003, and Kelly Aerospace Power Systems Service Information Letter Bulletin No. A-110A, dated March 6, 2003.

End Further Info End Preamble Start Supplemental Information

SUPPLEMENTARY INFORMATION:

What events have caused this AD? Several reports of fuel leakage (resulting from a quality control problem) from the combustion heater fuel pumps installed on Piper Models PA-34-200T, PA-34-220T, PA-44-180, and PA-44-180T airplanes caused us to issue AD 2003-11-14, Amendment 39-13173 (68 FR 33356, June 4, 2003). AD 2003-11-14 currently requires you to do a one-time (quality control) inspection of the combustion heater fuel pumps for fuel leakage. If leakage is found, repair or replace the fuel pump.

Since AD 2003-11-14 was issued, there has been an investigation of two reports of fuel leakage from the combustion heater fuel pumps in December 2004. These two reports of fuel leakage were similar to those that led to the issuance of AD 2003-11-14. Improper torque was applied to the mounting screws of the fuel pump filter cover and resulted in sealing surface abnormalities such as nicks, gouges, or warping. This condition is a result of a quality control problem.

The findings of the investigation concluded that after issuance of AD 2003-11-14 additional fuel pumps that did not meet the quality control (inspection or design) requirements of the AD have been installed in Piper Models PA-34-220T and PA-44-180 airplanes. Other fuel pumps that do not meet the quality control (inspection or design) requirements may be held as spares.

What is the potential impact if FAA took no action? Quality control problems with the heater fuel pump could result in failure of the heater fuel pump. Such failure could lead to fire or explosion in the cockpit.

Is there service information that applies to this subject? Piper has issued:

—Service Bulletin No. 1127, dated February 26, 2003. This Piper service bulletin includes Kelly Aerospace Service Information Letter Bulletin No. A-110A, dated March 6, 2003; and

—Service Bulletin No. 1127B, dated April 18, 2005. This Piper service bulletin includes Kelly Aerospace Service Information Letter Bulletin No. A-110B, dated December 20, 2004

What are the provisions of this service information? These service bulletins include procedures for:

—Inspecting the combustion heater fuel pump for leaks; and

—Inspecting the sealing surface of the fuel pump.

FAA's Determination and Requirements of the AD

What has FAA decided? We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design.

Since the unsafe condition described previously is likely to exist or develop on other Piper Models PA-34-200T, PA-34-220T, PA-44-180, and PA-44-180T airplanes of the same type design, we are issuing this AD to correct quality control problems with the heater fuel pump, which could result in failure of the heater fuel pump. Such failure could lead to fire or explosion in the cockpit.

What does this AD require? This AD requires you to incorporate the actions in the previously-referenced service bulletins.

In preparing this rule, we contacted type clubs and aircraft operators to get technical information and information on operational and economic impacts. We did not receive any information through these contacts. If received, we would have included a discussion of any information that may have influenced this action in the rulemaking docket.

How does the revision to 14 CFR part 39 affect this AD? On July 10, 2002, we 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 altered products, special flight permits, and alternative methods of compliance. 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.

Comments Invited

Will I have the opportunity to comment before you issue the rule? This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to submit any written relevant data, views, or arguments regarding this AD. Send your comments to an address listed under ADDRESSES. Include “Docket No. FAA-2005-21590; Directorate Identifier 2005-CE-33-AD” in the subject line of your comments. If you want us to acknowledge receipt of your mailed comments, send us a self-addressed, stamped postcard with the docket number written on it; we will date-stamp your postcard and mail it back to you. We specifically invite comments Start Printed Page 43031on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify it. If a person contacts us through a nonwritten communication, and that contact relates to a substantive part of this AD, we will summarize the contact and place the summary in the docket. We will consider all comments received by the closing date and may amend the AD in light of those comments.

Authority for This Rulemaking

What authority does FAA have for issuing this rulemaking action? Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency's authority.

We are issuing this rulemaking under the authority described in subtitle VII, part A, subpart III, section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this AD.

Regulatory Findings

Will this AD impact various entities? We have determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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.

Will this AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this AD:

1. Is not a “significant regulatory action” under Executive Order 12866;

2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

3. 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.

We prepared a summary of the costs to comply with this AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include “AD Docket FAA-2005-21590; Directorate Identifier 2005-CE-33-AD” in your request.
