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 describes the unsafe condition as:

Damaged lower skin of the fuselage aft tail cone was found during a preflight inspection of a P2006T aeroplane. This damage was caused by the lower lid of the emergency accumulator for the extension of the landing gear. The lid had detached from the emergency accumulator, violently hitting the lower skin of the fuselage aft tail cone and damaging the accumulator cylinder.

This condition, if not detected and corrected, could impair the aeroplane structural integrity and jeopardize the landing gear emergency extension in case of system failure in normal mode.

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 September 22, 2011.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No.: 2011-0063-E, dated April 6, 2011 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

Damaged lower skin of the fuselage aft tail cone was found during a preflight inspection of a P2006T aeroplane. This damage was caused by the lower lid of the emergency accumulator for the extension of the landing gear. The lid had detached from the emergency accumulator, violently hitting the lower skin of the fuselage aft tail cone and damaging the accumulator cylinder.

This condition, if not detected and corrected, could impair the aeroplane structural integrity and jeopardize the landing gear emergency extension in case of system failure in normal mode.

For the above described reasons, EASA AD 2011-0059-E required an inspection of the emergency accumulator cylinder for absence of crack, deformation or oil leakage, and the accomplishment of the applicable corrective actions.

This AD, which supersedes EASA AD 2011-0059-E partially retaining its requirements, reduces the compliance time for the required inspection, as other failures of the emergency accumulator have occurred since AD 2011-0059-E was issued.

This AD is considered to be an interim measure and, after approval of a modification already designed by the Type Certificate holder, further AD actions may follow.

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

Relevant Service Information

Costruzioni Aeronautiche Tecnam has issued Service Bulletin No. SB 047-CS, Revision 1, dated April 4, 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.Start Printed Page 48046

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 3 products of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $255, or $85 per product.

In addition, we estimate that any necessary follow-on actions would take about 1 work-hour and require parts costing $800, for a cost of $885 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.

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.

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

Start Part

PART 39—AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Start Authority

Authority: 49 U.S.C. 106(g), 40113, 44701.

End Authority
[Amended]

2. The FAA amends § 39.13 by adding the following new AD:

Costruzioni Aeronautiche Tecnam srl: Docket No. FAA-2011-0816; Directorate Identifier 2011-CE-022-AD.

Comments Due Date

(a) We must receive comments by September 22, 2011.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Costruzioni Aeronautiche Tecnam srl P2006T airplanes, serial number (S/N) 001/US through S/N 065/US, certificated in any category.

Subject

(d) Air Transport Association of America (ATA) Code 32: Landing Gear.

Reason

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

Damaged lower skin of the fuselage aft tail cone was found during a preflight inspection of a P2006T aeroplane. This damage was caused by the lower lid of the emergency accumulator for the extension of the landing gear. The lid had detached from the emergency accumulator, violently hitting the lower skin of the fuselage aft tail cone and damaging the accumulator cylinder.

This condition, if not detected and corrected, could impair the aeroplane structural integrity and jeopardize the landing gear emergency extension in case of system failure in normal mode.

For the above described reasons, EASA AD 2011-0059-E required an inspection of the emergency accumulator cylinder for absence of crack, deformation or oil leakage, and the accomplishment of the applicable corrective actions.

This AD, which supersedes EASA AD 2011-0059-E partially retaining its requirements, reduces the compliance time for the required inspection, as other failures of the emergency accumulator have occurred since AD 2011-0059-E was issued.

This AD is considered to be an interim measure and, after approval of a modification already designed by the Type Certificate holder, further AD actions may follow.

Actions and Compliance

(f) Unless already done, before further flight after the effective date of this AD, do the following actions following Costruzioni Aeronautiche Tecnam Service Bulletin No. SB 047-CS, Edition 1, Revision 1, dated April 4, 2011:

(1) Inspect the emergency accumulator part number (P/N) 22-9-610-000 for cracks, deformities, or oil leaks.

(2) If during the inspection required by paragraph (f)(1) of this AD any cracks, deformities, or oil leaks are found, before further flight, replace the emergency accumulator P/N 22-9-610-000 with a serviceable part, following the instructions in Costruzioni Aeronautiche Tecnam P2006T Maintenance Manual, 2nd Edition, Revision 1, dated April 27, 2011, Chapter 29-10, paragraph 5.
