AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

The FAA is adopting a new airworthiness directive (AD) for certain Polskie Zaklady Lotnicze Spolka zo.o. Model PZL M26 01 airplanes. This AD requires you to repetitively inspect fuselage frame No. XI for cracks and to replace fuselage frame No. XI and install reinforcement modifications if any cracks are found. The installation of reinforcement modifications is terminating action for the repetitive inspection requirement. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the European Union. We are issuing this AD to detect and correct cracks in fuselage frame No. XI, which could result in failure of this frame. This failure could lead to failure of the tail section of the airplane.

DATES:

This AD becomes effective on February 24, 2006.

As of February 24, 2006, the Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation.

We must receive any comments on this AD by March 13, 2006.

SUPPLEMENTARY INFORMATION:

Discussion

What events have caused this AD? The European Aviation Safety Agency (EASA), which is the airworthiness authority for the European Union, recently notified FAA that an unsafe condition may exist on certain Polskie Zaklady Lotnicze Spolka zo.o. Model PZL M26 01airplanes. The EASA reports that during the inspection of a Polskie Zaklady Lotnicze Spolka zo.o. Model PZL M26 01 airplane, cracks were found in frame no. XI at the rear of the fuselage.

The EASA further reports that the type certificate holder, Polskie Zaklady Lotnicze Spolka zo.o., believes that these cracks in the fuselage are due to excessive stresses generated by vertical tail loads when operating the airplane in the aerobatic category.

What is the potential impact if FAA took no action? Cracks in fuselage frame No. XI could result in failure of this frame and the tail section of the airplane.

Is there service information that applies to this subject? Polskie Zaklady Lotnicze Spolka zo.o. has issued Bulletin No. E/62.018/2005, dated November 30, 2005.

What are the provisions of this service information? The service bulletin includes procedures for:

—Inspecting for cracks in fuselage frame No. XI;

—Replacing fuselage frame No. XI; and

—Installing reinforcement modifications for fuselage frame No. XI.

What action did the EASA take? The EASA classified this service bulletin as mandatory and issued EASA AD Number 2006-0011-E, dated January 12, 2006, to ensure the continued airworthiness of these airplanes in the European Union.

Did the EASA inform the United States under the bilateral airworthiness agreement? These Polskie Zaklady Lotnicze Spolka zo.o. Model PZL M26 01 airplanes are manufactured in Poland (a member state of the European Union and EASA) and are type-certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement.

Under this bilateral airworthiness agreement, the EASA has kept us informed of the situation described above.

FAA's Determination and Requirements of This AD

What has FAA decided? We have examined the EASA's findings, reviewed all available information, and determined that we need to issue an AD for products of this type design that are certificated for operation in the United States.

Since the unsafe condition described previously is likely to exist or develop on other Polskie Zaklady Lotnicze Spolka zo.o. Model PZL M26 01 airplanes of the same type design that are registered in the United States, we are issuing this AD to detect and correct cracks in fuselage frame No. XI, which could result in failure of this frame and the tail section of the airplane.

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

In preparing this rule, we contacted type clubs and aircraft operators to get Start Printed Page 6974technical 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.

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 “Docket No. FAA-2006-23733; Directorate Identifier 2006-CE-09-AD” in your request.
