AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI references Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, which describes the unsafe condition as:

REAR AND FORWARD SUPPORTS OF BOTH HORIZONTAL STABILIZER MODIFICATION. It have been found on several of the affected airplanes some severe corrosion and cracks in both supports. The probable cause for those failures is the accumulation of steam or application products vapors.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

DATES:

We must receive comments on this proposed AD by March 16, 2007.

ADDRESSES:

You may send comments by any of the following methods:

  • DOT Docket Web Site: Go to http://dms.dot.gov and follow the instructions for sending your comments electronically.

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. This streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products.

This proposed AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The proposed AD contains text copied from the MCAI and for this reason might not follow our plain language principles.

Comments Invited

We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2007-27109; Directorate Identifier 2007-CE-005-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments.

We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD.

Discussion

The Dirección Nacional de Aeronavegabilidad (DNA), which is the aviation authority for Republica Argentina, has issued AD No. RA 2006-06-01, Rev. 1 LAVIA S.A., Amendment No. 39/03-041, dated November 17, 2006 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI references Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, which states:

REAR AND FORWARD SUPPORTS OF BOTH HORIZONTAL STABILIZER MODIFICATION. It have been found on several of the affected airplanes some severe corrosion and cracks in both supports. The probable cause for those failures is the accumulation of steam or application products vapors.

The MCAI requires:

Compliance with Service Bulletin No. 25/53/03 issued by Latinoamericana de Aviación S.A. is required in order to detect cracks, evidence of corrosion or any other anomalies on support tubes of the horizontal stabilizer.

You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Latinoamericana de Aviación S.A. has issued Service Bulletin No. 25/53/03, dated May 10, 2006. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the Proposed AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

Differences Between This Proposed AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information Start Printed Page 6983provided in the MCAI and related service information.

We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD.

Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 1,144 products of U.S. registry. We also estimate that it would take about 10 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $845 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $1,881,880, or $1,645 per product.

Authority for This Rulemaking

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 rulemaking action.

Regulatory Findings

We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD 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.

For the reasons discussed above, I certify this proposed regulation:

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 regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Comments Due Date

(a) We must receive comments by March 16, 2007.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Models PA-25, PA-25-235, and PA-25-260, all serial numbers up to LA-260-06008, certificated in any category.

Subject

(d) Air Transport Association of America (ATA) Code 55: Stabilizers.

Reason

(e) The mandatory continuing airworthiness information (MCAI) references Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, which states:

REAR AND FORWARD SUPPORTS OF BOTH HORIZONTAL STABILIZER MODIFICATION. It has been found on several of the affected airplanes some severe corrosion and cracks in both supports. The probable cause for those failures is the accumulation of steam or application products vapors.

Actions and Compliance

(f) Unless already done, do the following actions:

(1) Upon accumulating 1,500 hours time-in-service (TIS) or within the next 50 hours TIS after the effective date of this AD, whichever occurs later, do the operations as specified in the paragraph “ACTIONS,” subparagraph “INITIAL” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006. Repetitively inspect thereafter every 100 hours TIS or 12 months, whichever occurs first, until the modification specified in paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, is done.

(2) If any evidence of cracks, signs of corrosion, or any other discrepancy is detected during any inspection required in paragraph (f)(1) of this AD, before further flight, disassemble both horizontal stabilizers and conduct a detailed inspection on the surface of both supports and take corrective action. Use paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006.

(3) After incorporating the modification specified in paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, no further action is required.

(4) Upon accumulating 1,000 hours TIS after the effective date of this AD, modify both horizontal stabilizers as specified in paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, unless already done. Incorporating this modification terminates the repetitive inspection requirement in paragraph (f)(1) of this AD.

(5) As a terminating action to the inspection requirements of this AD, the modification to both horizontal stabilizers specified in paragraph “ACTIONS,” subparagraph “DEFINITIVE” of Latinoamericana de Aviación S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, may be incorporated at any time after the effective date of this AD and before the time required in paragraph (f)(4) of this AD.
