2008-08-15	DORNIER LUFTFAHRT GMBH: Amendment 39-15467; Docket No. FAA-2008-0197; Directorate Identifier 2008-CE-005-AD.

EFFECTIVE DATE

(a) This airworthiness directive (AD) becomes effective May 27, 2008.

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

    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 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

PREAMBLE

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.

ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC 20590.

FOR FURTHER INFORMATION CONTACT: Karl Schletzbaum, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4146; fax: (816) 329-4090.

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:

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

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.
