Start Preamble

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 Start Printed Page 56749an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

The manufacturer has advised that the combination of a redesigned tail spring support with a stiffer tail spring and rough field operations has led to cracks in the tail spring support mounting base. Cracks have also been reported on aeroplanes already compliant with Part II of Extra Service Bulletin No. SB-300-2-97 issue A, as mandated by the LBA AD D-1998-001, dated 15 January 1998.

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 December 18, 2009.

Discussion

The European Aviation Safety Agency, which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2009-0160, July 21, 2009 (corrected on July 28, 2009) (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

The manufacturer has advised that the combination of a redesigned tail spring support with a stiffer tail spring and rough field operations has led to cracks in the tail spring support mounting base. Cracks have also been reported on aeroplanes already compliant with Part II of Extra Service Bulletin No. SB-300-2-97 issue A, as mandated by the LBA AD D-1998-001, dated 15 January 1998.

For the reasons stated above, this new AD mandates instructions for recurring inspections and modification in the area of the tail spring support in order to prevent separation of the tail landing gear which could result in serious damage to the airplane during landing.

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

Relevant Service Information

Extra Flugzeugproduktions- und Vertriebs-GmbH has issued EXTRA Service Bulletin No. SB-300-2-97, Issue: C, dated September 24, 2009. 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 provided 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

We estimate that this proposed AD will affect 184 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $29,440, or $160 per product.

In addition, we estimate that any necessary follow-on actions would take about 20 work-hours and require parts costing $460, for a cost of $2,060 per product. We have no way of determining the number of products that may need these actions.

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.Start Printed Page 56750

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 December 18, 2009.

Affected ADs

(b) None.

Applicability

(c) This AD applies to the following model and serial number airplanes, certificated in any category:

(1) Model EA-300/200 airplanes, serial numbers (S/N) 01 through 31, and 1032 through 1043; and

(2) Model EA-300/L airplanes, S/N 01 through 170, 172, 173, 1171, and 1174 through 1299.

Subject

(d) Air Transport Association of America (ATA) Code 53: Fuselage.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

“The manufacturer has advised that the combination of a redesigned tail spring support with a stiffer tail spring and rough field operations has led to cracks in the tail spring support mounting base. Cracks have also been reported on aeroplanes already compliant with Part II of Extra Service Bulletin No. SB-300-2-97 issue A, as mandated by the LBA AD D-1998-001, dated 15 January 1998.

“For the reasons stated above, this new AD mandates instructions for recurring inspections and modification in the area of the tail spring support in order to prevent separation of the tail landing gear which could result in serious damage to the airplane during landing.”

Actions and Compliance

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

(1) Before further flight after the effective date of this AD and repetitively thereafter at intervals not to exceed 50 hours time-in-service, inspect the tail spring support for cracks in accordance with PART I of Extra Flugzeugproduktions- und Vertriebs-GmbH EXTRA Service Bulletin No. SB-300-2-97, Issue: C, dated September 24, 2009.

(2) If any crack is found as a result of the inspections required by paragraph (f)(1) of this AD, before further flight, modify the tail spring support structure as instructed in PART II of Extra Flugzeugproduktions- und Vertriebs-GmbH EXTRA Service Bulletin No. SB-300-2-97, Issue: C, dated September 24, 2009. Modification of the tail spring support structure terminates the repetitive inspections required in paragraph (f)(1) of this AD.

(3) You may at any time modify the tail spring support structure as instructed in PART II of Extra Flugzeugproduktions- und Vertriebs-GmbH EXTRA Service Bulletin No. SB-300-2-97, Issue: C, dated September 24, 2009, to terminate the repetitive inspections required in paragraph (f)(1) of this AD.
