The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Costruzioni Aeronautiche Tecnam S.P.A. Model P2006T airplanes. The NPRM published in the Federal Register on August 25, 2021 (86 FR 47422). The NPRM was prompted by MCAI originated by the European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD 2019-0043, dated March 6, 2019 (referred to after this as “the MCAI”), to correct an unsafe condition for Costruzioni Aeronautiche Tecnam S.P.A. Model P2006T airplanes. The MCAI states:

Failures of NLG piston tubes P/N 26-8-1408-1 were reported during ground operations. Subsequent investigation determined a deficiency in NLG piston tube manufacturing process. It was also determined that only a specific batch is affected by this defect.

This condition, if not corrected, could lead to failure of the NLG, possibly resulting in loss of control on the ground, during or after landing, with consequent damage to the aeroplane and injury to occupants.

To address this potential unsafe condition, TECNAM issued the [service bulletin] SB to provide instructions for the replacement of each affected part with a part that was manufactured by an improved process.

For the reasons described above, this [EASA] AD requires removal from service of the affected parts.

You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-0700.

The FAA received no comments on the NPRM or on the determination of the costs.

This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA's bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM.

Costruzioni Aeronautiche Tecnam S.P.A. Service Bulletin No. SB 288-CS-Ed 1, Revision 1, dated December 22, 2017, is related to this AD and provides information about installing nose landing gear (NLG) piston tube kit number SB 288-1.

The FAA estimates that this AD affects 59 airplanes of U.S. registry. The FAA also estimates it will take about 4 work-hours per airplane to comply with the replacement required by this AD and required parts would cost about $1,200 per airplane. The average labor rate is $85 per work-hour.

Based on these figures, the FAA estimates the cost of this AD on U.S. operators to be $90,860 or $1,540 per airplane.

The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators.

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.

The FAA is 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.

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 that this AD:

(1) Is not a “significant regulatory action” under Executive Order 12866,

(2) Will not affect intrastate aviation in Alaska, 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.

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

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

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