Airworthiness Directives; DORNIER LUFTFAHRT GmbH Models 228-100, 
228-101, 228-200, 228-201, 228-202, and 228-212 Airplanes

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

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
DORNIER LUFTFAHRT GmbH Models 228-100, 228-101, 228-200, 228-201, 228-
202, and 228-212 airplanes. This AD requires you to repetitively 
inspect the wiring in the flight deck overhead panels (locations 5VE 
and 6VE) for chafing and damage and repair any chafed or damaged wires. 
Regardless of the results of each inspection, this AD requires you to 
assure correct installation of the wiring in the flight deck overhead 
panels by reattaching or replacing the wire tie attachment holders and 
securing any loose wires to the wire tie attachment holders with 
plastic wire ties. This AD results from mandatory continuing 
airworthiness information (MCAI) issued by the airworthiness authority 
for Germany. We are issuing this AD to detect, correct, and prevent 
chafed or damaged wires in the flight deck overhead panels, which could 
result in short-circuiting of related wiring. This condition could lead 
to electrical failure of affected systems and potential fire in the 
flight deck.

DATES: This AD becomes effective on July 14, 2006.
    As of July 14, 2006, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in the 
regulation.

SUPPLEMENTARY INFORMATION:

Discussion

    On March 22, 2006, we issued a proposal to amend part 39 of the 
Federal Aviation Regulations (14 CFR part 39) to include an AD that 
would apply to DORNIER LUFTFAHRT GmbH (DORNIER) Models 228-100, 228-
101, 228-200, 228-201, 228-202, and 228-212 airplanes. This proposal 
was published in the Federal Register as a notice of proposed 
rulemaking (NPRM) on March 29, 2006 (71 FR 15647). The NPRM proposed to 
require you to repetitively inspect the wiring in the flight deck 
overhead panels (locations 5VE and 6VE) for chafing and damage and 
repair any chafed or damaged wires. Regardless of the results of each 
inspection, the NPRM would require you to assure correct installation 
of the wiring in the flight deck overhead panels by reattaching or 
replacing the wire tie attachment holders and securing any loose wires 
to the wire tie attachment holders with plastic wire ties.

Comments

    We provided the public the opportunity to participate in developing 
this AD. We received no comments on the proposal or on the 
determination of the cost to the public.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD as proposed 
except for minor editorial corrections. We have determined that these 
minor corrections:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

    We estimate that this AD affects 14 airplanes in the U.S. registry.
    We estimate the following costs to do the inspection:

[[Page 32269]]



----------------------------------------------------------------------------------------------------------------
                                                         Total cost  per
           Labor costs                 Parts costs           airplane          Total cost  on U.S. operators
----------------------------------------------------------------------------------------------------------------
2 workhours x $80 per hour = $160  Not applicable.....               $160  $160 x 14 = $2,240.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
will be required based on the results of the inspection. We have no way 
of determining the number of airplanes that may need this repair:

----------------------------------------------------------------------------------------------------------------
                     Labor cost                        Parts cost              Total cost  per airplane
----------------------------------------------------------------------------------------------------------------
3 workhours x $80 per hour = $240..................            $100  $240 + $100 = $340.
----------------------------------------------------------------------------------------------------------------


    Note: The cure time for the adhesive that is recommended in the 
service information is 48 hours at 25 degrees Celsius (77 degrees 
Fahrenheit) or 2 hours at 65 degrees Celsius (149 degrees 
Fahrenheit).

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 AD.

Regulatory Findings

    We have 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 that 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 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 summary of the costs to comply with this AD (and 
other information as included in the Regulatory Evaluation) and placed 
it in the AD Docket. You may get a copy of this summary by sending a 
request to us at the address listed under ADDRESSES. Include ``Docket 
No. FAA-2006-24095; Directorate Identifier 2006-CE-21-AD'' in your 
request.
