14 CFR Part 39

[Docket No. FAA-2005-22813; Directorate Identifier 2002-NM-117-AD; 
Amendment 39-14493; AD 2000-24-03 R1]

Airworthiness Directives; AvCraft Dornier Model 328-100 Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is revising an existing airworthiness directive (AD) 
that applies to all AvCraft Dornier Model 328-100 airplanes. That AD 
currently requires revising the airplane flight manual (AFM) to provide 
the flightcrew with additional information regarding procedures to 
ensure complete pressurization of the hydraulic lines for the flaps. 
The existing AD also requires, for certain airplanes, modifying of the 
flap actuators of the flight controls. We issued that AD to prevent an 
uncommanded retraction of the flaps during takeoff, which could result 
in an aborted takeoff and consequent potential for runway overrun. This 
new AD allows the removal of the AFM revisions after modifying the flap 
actuators of the flight controls. This AD results from the 
determination that the AFM revisions are not necessary after modifying 
the flap actuators of the flight controls. We are issuing this AD to 
prevent an uncommanded retraction of the flaps during takeoff, which 
could result in an aborted takeoff and consequent potential for runway 
overrun.

DATES: The effective date of this AD is January 8, 2001.
    On January 8, 2001 (65 FR 75601, December 4, 2000), the Director of 
the Federal Register approved the incorporation by reference of Dornier 
328 All Operators Telefax AOT-328-27-016, Revision 1, dated October 28, 
1998; and Dornier 328 Service Bulletin SB-328-27-293, dated November 
10, 1999.
    On November 12, 1998 (63 FR 57244, October 27, 1998), the Director 
of the Federal Register approved the incorporation by reference of 
Dornier 328 All Operators Telefax AOT-328-27-016, dated July 31, 1998.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the AD docket on the Internet at http://dms.dot.gov 
or in person at the Docket Management Facility office between 9 a.m. 
and 5 p.m., Monday through Friday, except Federal holidays. The Docket 
Management Facility office (telephone (800) 647-5227) is located on the 
plaza level of the Nassif Building at the street address stated in the 
ADDRESSES section.

Discussion

    The FAA proposed to amend part 39 of the Federal Aviation 
Regulations (14 CFR part 39) with an airworthiness directive (AD) to 
revise AD 2000-24-03, amendment 39-12010 (65 FR 75601, December 4, 
2000). The existing AD applies to all Dornier Model 328-100 series 
airplanes. The proposed AD was published in the Federal Register on 
November 1, 2005 (70 FR 65864) to continue to require revising the 
airplane flight manual (AFM) to provide the flightcrew with additional 
information regarding procedures to ensure complete pressurization of 
the hydraulic lines for the flaps, and for certain airplanes, modifying 
the flap actuators of the flight controls. The proposed AD also 
proposed to allow the removal of the AFM revisions after modifying the 
flap actuators of the flight controls.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the NPRM 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.

Costs of Compliance

    We estimate that 52 airplanes of U.S. registry will be affected by 
this AD.
    The AFM revision that is currently required by AD 2000-24-03, and 
retained in this AD, takes approximately 1 work hour per airplane to 
accomplish, at an average labor rate of $65 per work hour. Based on 
these figures, the cost impact of the currently required AFM revision 
on U.S. operators is approximately $3,380, or $65 per airplane.
    The modification that is currently required by AD 2000-24-03, and 
retained in this AD, takes approximately 4 work hours per airplane to 
accomplish, at an average labor rate of $65 per work hour. Required 
parts will be provided by the manufacturer at no cost to the operators. 
Based on these figures, the cost impact of the currently required 
modification on U.S. operators is estimated to be $260 per airplane.
    The removal of the AFM revisions that is specified in this AD, if 
done, takes approximately 1 work hour per airplane to accomplish, at an 
average labor rate of $65 per work hour. Based on these figures, the 
cost impact of the removal of AFM revisions on U.S. operators is 
approximately $65 per airplane.

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.

[[Page 9256]]

    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 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 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

AD. Concurrently with this AFM revision, remove the AFM revisions 
required by paragraph (f) of this AD from the AFM.
    (1) Revise the Normal Procedures section to include the 
information specified in pages 4, 5, and 6 of Dornier 328 AOT-328-
27-016, Revision 1, dated October 28, 1998. This may be accomplished

AFM.

    Note 1: The Dornier service bulletin references Liebherr 
Aerospace Service Bulletin 1048A-27-02, dated November 9, 1999, as 
an additional source of service information for accomplishing the 
modification of the flap actuators of the flight controls.

Alternative Methods of Compliance (AMOCs)

    (i)(1) The Manager, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, has the authority to approve AMOCs for 
this AD, if requested in accordance with the procedures found in 14
