Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding an existing 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 July 17, 2009.

On July 17, 2009, 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 March 30, 2009 (74 FR 14097), and proposed to supersede AD 2008-08-15, Amendment 39-15467 (73 FR 21220; April 21, 2008). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that:

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.

Corrosion damage can occur through insufficient surface protection. Consequently, the MCAI requires a detailed visual inspection of the inner structure of the rudder and elevator for signs of corrosion, de-bonded primer (yellow-green), and any deviation of surface protection. If the inspection results show corrosion beyond the acceptable level or areas with de-bonded primer, the inspection results have to be reported to RUAG Aerospace Services GmbH for further decisions. If necessary, repair the affected parts in accordance with the applicable repair instruction obtained from RUAG Aerospace Services GmbH.

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. Any such differences are highlighted in a note within the AD.

Costs of Compliance

We estimate that this AD will affect 17 products of U.S. registry. We also estimate that it will take about 3 work-hours per product to comply with the 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 $4,080, or $240 per product.

We have no way of determining the number of airplanes or the associated costs of any follow-on repairs or replacements that might be required by this AD.

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.

(1) Are certificated in any category; andStart Printed Page 27908

(2) have had the rudder and/or elevator replaced or repaired at Fairchild Dornier or RUAG between the year 2000 and 2005. The concerned rudder and elevator part numbers and serial numbers are listed on page 7 of RUAG Aerospace Defence Technology Dornier 228 Service Bulletin No. SB-228-270 (includes undated attachments 1 and 2 to SB-228-270 Rev. 1), Rev. No. 1, dated November 28, 2008.

Subject

(d) Air Transport Association of America (ATA) Code 51: Standard Practices/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.

Corrosion damage can occur through insufficient surface protection. Consequently, the MCAI requires a detailed visual inspection of the inner structure of the rudder and elevator for signs of corrosion, de-bonded primer (yellow-green), and any deviation of surface protection. If the inspection results show corrosion beyond the acceptable level or areas with de-bonded primer, the inspection results have to be reported to RUAG Aerospace Services GmbH for further decisions. If necessary, repair the affected parts in accordance with the applicable repair instruction obtained from RUAG Aerospace Services GmbH.

Actions and Compliance

(f) Unless already done, do the following actions:

(1) Within 2 months after July 17, 2009 (the effective date of this AD), do a detailed visual inspection on the inner structure of the rudder and elevator for signs of corrosion, de-bonded primer (yellow-green), and any other deviation of surface protection following RUAG Aerospace Defence Technology Dornier 228 Service Bulletin No. SB-228-270 (includes undated attachments 1 and 2 to SB-228-270 Rev. 1), Rev. No. 1, dated November 28, 2008.

(2) If you find corrosion or areas with de-bonded 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: +49 (0) 8153-30-2280; fax: +49 (0) 8153-30-3030 and request FAA-approved repair instructions following RUAG Aerospace Defence Technology Dornier 228 Service Bulletin No. SB-228-270 (includes undated attachments 1 and 2 to SB-228-270 Rev. 1), Rev. No. 1, dated November 28, 2008.

(ii) Repair corrosion following FAA-approved repair instructions obtained from RUAG Aerospace Services GmbH.
