**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 cracking, bulging, deformation, or oil leakage in the lower lid of the landing gear emergency accumulator, which could result in decreasing the airplane’s structural integrity and jeopardizing the landing gear emergency extension in case of system failure in normal mode. We are issuing this AD to require actions to address the unsafe condition on these products.

**SUPPLEMENTARY INFORMATION**

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That SNPRM was published in the Federal Register on June 13, 2012 (77 FR 35304). That SNPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

During a pre-flight inspection of a P2006T aeroplane, the lower skin of the fuselage aft tail cone was found damaged. This damage was caused by the lower lid of the LG emergency accumulator, which had detached from the LG 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 LG emergency extension in case of system failure in normal mode.

For the reasons described above, EASA issued Emergency AD 2011–0063–E to require a one-time inspection of the LG emergency accumulator cylinder for cracks, deformation or oil leakage and, depending on findings, the accomplishment of the applicable corrective actions.

After that AD was issued, Costruzioni Aeronautiche TECNAM developed a modification (MOD 2006–108) and published Service Bulletin (SB) SB–048–CS Revision 1, dated 06 July 2011, that contained the instructions for that modification. Prompted by this development, EASA issued PAD 11– 070 for consultation until 16 August 2011, proposing to require incorporation of this modification on all affected aeroplanes, and to require certain post-modification repetitive inspections.

During the consultation period of PAD 11– 070, an operator who had applied Costruzioni Aeronautiche TECNAM SB–048– CS on his aeroplane, reported finding abnormal deformation of the emergency accumulator, to such an extent that it would jeopardize the LG emergency extension in case of system failure in normal mode. To address this additional safety concern, Costruzioni Aeronautiche TECNAM issued SB–068–CS which contains instructions to inspect post-modification aeroplanes.

For the reasons described above, EASA AD 2011–0153–E retained the requirements of EASA AD 2011–0063–E, which was superseded, and required modification of the landing gear emergency accumulator by installation of safety rings and repetitive inspections after modification. In addition,


## 56992 Federal Register / Vol. 77, No. 180 / Monday, September 17, 2012 / Rules and Regulations

prompted by the recent post-modification findings, EASA AD 2011–0153–E reduced the compliance time for the modification as originally proposed and required additional first-flight-of-the-day repetitive inspections for the LG emergency accumulator cylinder and replacement of the LG emergency accumulator if cracks, deformation, or oil leakage is detected.

AD Revision 2011–0153R1 was issued in order to allow Pilot-Owners to accomplish the daily pre-flight inspection of the modified LG emergency accumulator.

After that AD Revision, Costruzioni Aeronautiche TECNAM designed a new LG emergency accumulator part number 26–9– 9500–000, identified as modification MOD 2006–121, and published SB–080–CS dated 02 January 2012, which contains instructions for replacement and installation of the newly designed LG emergency accumulator.

This AD, which supersedes EASA AD 2011–0153R1, requires the installation of the new landing gear emergency accumulator part number 26–9–9500–000, as well as to inspect after the installation the LG emergency accumulator and the LG retraction/extension system.



### Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the SNPRM (77 FR 35304, June 13, 2012) for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the SNPRM (77 FR 35304, June 13, 2012). Costs of Compliance

We estimate that this proposed AD will affect 7 products of U.S. registry. We also estimate that it would take about 7 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $1,300 per product.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $13,265, or $1,895 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 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.

For the reasons discussed above, I certify 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),

(3) Will not affect intrastate aviation in Alaska, and

(4) 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. Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.
