AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. 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:
The manufacturer reported findings of missing primer on the internal of the elevator and rudder of aircraft S/N 8200. The aircraft S/N 8200 was with RUAG for maintenance purposes.
Investigation performed by RUAG showed that the paint removal procedure for the rudder and elevator was changed from a paint stripping with brush and scraper to a procedure where the parts were submerged in a tank filled with hot liquid stripper. The stripper is called TURCO 5669 from Henkel Surface Technologies. The stripping process is described in the Technical Process Bulletin No. 238799 dated 09/01/1999. This paint stripping process change was not communicated to and not approved by the TC-Holder.
We are issuing this AD to require actions to correct the unsafe condition on these products.
DATES: This AD becomes effective May 27, 2008.
On May 27, 2008, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION:
Discussion
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 Federal Register on February 25, 2008
(73 FR 9965). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:
The manufacturer reported findings of missing primer on the internal of the elevator and rudder of aircraft S/N 8200. The aircraft S/N 8200 was with RUAG for maintenance purposes.
Investigation performed by RUAG showed that the paint removal procedure for the rudder and elevator was changed from a paint stripping with brush and scraper to a procedure where the parts were submerged in a tank filled with hot liquid stripper. The stripper is called TURCO 5669 from Henkel Surface Technologies. The stripping process is described in the Technical Process Bulletin No. 238799 dated 09/01/1999. This paint stripping process change was not communicated to and not approved by the TC-Holder.
Comments
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.
Conclusion
We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.
Differences Between This 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 required different actions in this AD from those in the MCAI in order to follow FAA policies.
Page 21221
Any such differences are highlighted in a NOTE within the AD.
Costs of Compliance
Based on the service information, we estimate that this AD will affect 8 products of U.S. registry. We also estimate that it will take about 3 work-hours per product to comply with basic requirements of this AD. The average labor rate is $80 per work-hour.
Based on these figures, we estimate the cost of this AD to the U.S. operators to be $1,920 or $240 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 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 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 AD and placed it in the AD Docket.
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. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

Affected ADs
(b) None.
Applicability
(c) This AD applies to Models 228-100, 228-101, 228-200, 228- 201, 228-202, and 228-212 airplanes, serial numbers 8009, 8065, 8112, 8179, 8185, 8191, 8241, and 8244, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 51:
Structures.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
The manufacturer reported findings of missing primer on the internal of the elevator and rudder of aircraft S/N 8200. The aircraft S/N 8200 was with RUAG for maintenance purposes. Investigation performed by RUAG showed that the paint removal procedure for the rudder and elevator was changed from a paint stripping with brush and scraper to a procedure where the parts were submerged in a tank filled with hot liquid stripper. The stripper is called TURCO 5669 from Henkel
Surface Technologies. The stripping process is described in the
Technical Process Bulletin No. 238799 dated 09/01/1999. This paint stripping process change was not communicated to and not approved by the TC-Holder.
The MCAI requires you to do a visual inspection of the inner structure on rudder and elevator for signs of corrosion, de-bonded primer (yellow-green), and any other deviation of surface protection; report corrosion beyond the acceptable level or areas with de-bonded primer to the manufacturer; and, if necessary, repair the affected parts following the applicable FAA-approved manufacturer repair instruction.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within 2 months after the effective date of this AD, do a detailed visual inspection on the inner structure of the rudder and elevator for signs of corrosion, debonded primer (yellow-green), and any other deviation of surface protection following RUAG Aerospace
Defence Technology Dornier 228 Service Bulletin No. SB-228-270, dated October 30, 2007.
(2) If you find corrosion or areas with debonded primer as a result of the inspection required by paragraph (f)(1) of this AD, before further flight, do the following:
(i) Report the inspection results to RUAG Aerospace Services
GmbH, Dornier 228 Customer Support, P.O. Box 1253, 82231 Wessling,
Federal Republic of Germany, telephone: 011-49-8153-30-2280; fax: 011-49-8153-30-3030, and request FAA-approved repair instructions following RUAG Aerospace Defence Technology Dornier 228 Service
Bulletin No. SB-228-270, dated October 30, 2007.
(ii) Repair corrosion following FAA-approved repair instructions obtained from RUAG Aerospace Services GmbH.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information as follows: The MCAI includes provisions for reporting corrosion
``beyond the acceptable level.'' However, the service information does not include a definition of ``acceptable level.'' Therefore, to ensure the AD is clear for U.S. operators and is enforceable, this
AD does not include the qualifier ``beyond the acceptable level.''
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Karl Schletzbaum, Aerospace Engineer, FAA,
Small Airplane Directorate, 901 Locust, Room 301, Kansas City,
Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090.
Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District
Page 21222
Office (FSDO), or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned
OMB Control Number 2120-0056.
