Federal Aviation Administration (FAA), DOT.
The FAA adopts a new airworthiness directive (AD) for certain The New Piper Aircraft, Inc. (Piper) Models PA-28-160, PA-28-161, PA-28-180, and PA-28-181 airplanes that incorporate Petersen Aviation, Inc. Supplemental Type Certificate (STC) SA2660CE installed between April 20, 1998, and April 1, 2005, and incorporate Petersen Aviation, Inc. Service Bulletin SB98-1. This AD requires you to replace the AN894-6-4 bushing screw thread expanders on the gascolator and bushing attached to the inlet of the top fuel pump with NAS1564-6-4J reducers and AN818-6 nuts. This AD results from reports of fuel leaks during the post STC installation tests. We are issuing this AD to prevent fuel fittings used in STC SA2660CE from leaking fuel in the engine compartment, which could result in an engine fire. This condition could lead to loss of control of the airplane.Start Printed Page 55246
This AD becomes effective on November 4, 2005.
As of November 4, 2005, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation.

What events have caused this AD? We have received reports of fuel leaks found during post fuel pump checks on Piper Models PA-28-160, PA-28-161, PA-28-180, and PA-28-181 airplanes after STC SA2660CE was incorporated.
STC SA2660CE enables the referenced airplanes to run on leaded and unleaded automotive gasoline, 91 minimum antiknock index (RON+MON).
The STC replaces the Piper electric boost pump with two different electric boost pumps. Subsequently, Petersen Aviation, Inc. Service Bulletin 98-1 provides for installation of a fuel flow bypass that incorporates an o-ring seal fuel fitting (AN894-6-4 bushing screw thread expander) on the flared tube fitting (AN826-6 tee). The internal shape of the AN894-6-4 bushing screw thread expander is intended to use an o-ring seal, but there is no corresponding o-ring seal location on the AN826-6 tee.
The AN894-6-4 bushing screw thread expander has clearance machining cut for the mating screw threads but does not provide a seal against the cone surface of the AN826-6 tee.
What is the potential impact if FAA took no action? If not prevented, fuel fittings used in STC SA2660CE could leak fuel in the engine compartment. Failure of these fittings could result in an engine fire. This condition could lead to loss of control of the airplane.
Has FAA taken any action to this point? We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Piper Models PA-28-160, PA-28-161, PA-28-180, and PA-28-181 airplanes that incorporate Petersen Aviation, Inc. STC SA2660CE installed between April 20, 1998, and April 1, 2005, and incorporate Petersen Aviation, Inc. Service Bulletin SB98-1. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on June 2, 2005 (70 FR 32273). The NPRM proposed to require you to replace the two AN894-6-4 bushing screw thread expanders on the two AN826-6 tees with AN818-6 nuts and NAS1564-6-4J reducers.
Was the public invited to comment? We provided the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal and FAA's response to each comment:
Comment Issue No. 1: These Airplanes Should Not be Flying
What is the commenter's concern? The commenter states that it is their opinion that this kind of problem aircraft should not be flying.
What is FAA's response to the concern? We do not agree with the commenter. We identified an unsafe condition and the purpose of an AD is to address that unsafe condition and maintain the continued safe operation of an existing airplane model. The solution to the defined unsafe condition is to replace certain parts with improved design parts. We determined that the unsafe condition is addressed through the actions of this AD.
We are not changing the final rule AD based on this comment.
Comment Issue No. 2: AD Is Not Necessary
What is the commenter's concern? Peterson Aviation states that parts have been distributed to owners of the affected airplanes with reimbursement for installation; therefore, offering an incentive for the owners/operators of the affected airplanes to install the new parts.
The commenter also states that the only leaks that have been found were during recent post installation checks. Airplanes that had the modification done previously and have been using it for several years do not appear to have the fuel leaks.
The commenter requests us to issue a Special Alert Information Bulletin (SAIB) to address this condition rather than issue an AD.
What is FAA's response to the concern? We do not agree with the commenter. As mentioned above, we have identified an unsafe condition and an AD is the regulatory action that we use to ensure that the unsafe condition is addressed on all affected airplanes.
SAIBs are for information only and are not mandatory. Therefore, an SAIB would not ensure that the unsafe condition is addressed on all affected airplanes.
We are not changing the final rule AD based on this comment.
What is FAA's final determination on this issue? We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections:
—Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
—Do not add any additional burden upon the public than was already proposed in the NPRM.
Changes to 14 CFR Part 39—Effect on the AD
How does the revision to 14 CFR part 39 affect this AD? On July 10, 2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs the 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.
Costs of Compliance
How many airplanes does this AD impact? We estimate that this AD affects 50 airplanes in the U.S. registry.
What is the cost impact of this AD on owners/operators of the affected airplanes? We estimate the following costs to do the modification:Start Printed Page 55247
|Labor cost||Parts cost||Total cost per airplane||Total cost on U.S. operators|
|1 work hour × $65 per hour = $65||Petersen Aviation will provide parts at no cost||Petersen Aviation will cover the cost for labor||Petersen Aviation will cover the cost for parts and labor.|
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.
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.
