We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the
This emergency AD with the effective date 11 June 2012 is prompted by a report from EASA of finding a non conforming air filter fitted to an overseas aircraft during maintenance. Investigation revealed that air filters with P/N 57.34.00.010 supplied by CEAPR between June 2009 and April 2012 may not have the metallic mesh inside the filter. This AD mandates an inspection of air filters with P/N 57.34.00.010 to determine if a metallic mesh is fitted.
We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.
We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. We have determined that these minor changes:
• Are consistent with the intent that was proposed in the NPRM (77 FR 44511, July 30, 2012) for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 44511, July 30, 2012).
We estimate that this AD will affect 10 products of U.S. registry. We also estimate that it will take about .5 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of this AD on U.S. operators to be $425, or 42.50 per product.
In addition, we estimate that any necessary follow-on actions will take about .5 work-hour and require parts costing $100 for a cost of $142.50 per product. We have no way of determining the number of products that may need these actions.
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.
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
(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.

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
49 U.S.C. 106(g), 40113, 44701.
This airworthiness directive (AD) becomes effective November 9, 2012.
This AD applies to Alpha Aviation Concept Limited Model R2160 airplanes, all serial numbers, certificated in any category.
Air Transport Association of America (ATA) Code 71: Power Plant.
This AD was prompted by reports of possible installation of non-conforming air filter elements that are not fitted with metallic mesh and could internally collapse resulting in disruption of the powerplant operation. We are issuing this AD to inspect the air filter element and replace if applicable.
Unless already done, do the following actions following Alpha Aviation Service Bulletin AA-SB-71-006, dated May 2012:
(1) Within the next 30 days time-in-service (TIS) after November 9, 2012 (the effective date of this AD), inspect the air filter part number (P/N) 57.34.00.010 to determine if it has been fitted with a perforated metal liner.
(2) If, after the inspection required in paragraph (f)(1) of this AD, the air filter part number (P/N) 57.34.00.010 is found to include the perforated metal liner, no further action is required.
(3) If, after the inspection required in paragraph (f)(1) of this AD, the air filter is found to not contain the perforated metal liner, before further flight, replace the air filter with a new air filter P/N 57.34.00.010 that does contain the perforated metal liner.
(4) After November 9, 2012 (the effective date of this AD), do not install any air filter P/N 57.34.00.010 that does not have the perforated metal liner depicted in Alpha Aviation Service Bulletin AA-SB-71-006, dated May 2012.
The following provisions also apply to this AD:
