[Docket No. FAA-2005-22813; Directorate Identifier 2002-NM-117-AD]
RIN 2120-AA64

Airworthiness Directives; AvCraft Dornier Model 328-100 Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to revise an existing airworthiness directive 
(AD) that applies to all AvCraft Dornier Model 328-100 airplanes. The 
existing 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, 
modification of the flap actuators of the flight controls. This 
proposed AD would allow the removal of the AFM revisions after 
modifying the flap actuators of the flight controls. This proposed AD 
results from the determination that the AFM revisions are not necessary 
after modifying the flap actuators of the flight controls. We are 
proposing 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: We must receive comments on this proposed AD by December 1, 
2005.

Discussion

    On November 20, 2000, we issued AD 2000-24-03, amendment 39-12010 
(65 FR 75601, December 4, 2000), for all Dornier Model 328-100 series 
airplanes. That AD 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. That AD also requires, for certain airplanes, modification 
of the flap actuators of the flight controls. That AD resulted from the 
development of a hardware modification to install a locking collar and 
locking sleeve at the actuator cylinder. 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.

Actions Since Existing AD Was Issued

    Since we issued AD 2000-24-03, we determined that the AFM revisions 
are not necessary after modifying the flap actuators of the flight 
controls. The modification specified in paragraph (c) of that AD is 
currently written as an additional requirement for certain airplanes to 
the revisions specified in paragraphs (a) and (b) of the AD. The 
modification specified in paragraph (c) of that AD is intended to be a 
terminating action for the revisions specified in paragraphs (a) and 
(b) of the AD.

FAA's Determination and Requirements of the Proposed AD

    This airplane model is manufactured in Germany and is type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. We have determined 
that AD action is necessary for airplanes of this type design that are

[[Page 65865]]

certificated for operation in the United States.
    This proposed AD would revise AD 2000-24-03 and would retain the 
requirements of the existing AD. This proposed AD would also allow 
operators to remove the AFM revisions inserted according to paragraphs 
(a) and (b) of that AD after operators modified the flap actuators of 
the flight controls according to paragraph (c) of that AD.

Change to Existing AD

    This proposed AD would retain all requirements of AD 2000-24-03. 
Since AD 2000-24-03 was issued, the AD format has been revised, and 
certain paragraphs have been rearranged. As a result, the corresponding 
paragraph identifiers have changed in this proposed AD, as listed in 
the following table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
                                           Corresponding requirement in
      Requirement in  AD 2000-24-03              this proposed AD
------------------------------------------------------------------------
Paragraph (a)...........................  Paragraph (f).
Paragraph (b)...........................  Paragraph (g).
Paragraph (c)...........................  Paragraph (h).
------------------------------------------------------------------------

Explanation of Change to Applicability

    We have revised the applicability of the existing AD to identify 
model designations as published in the most recent type certificate 
data sheet for the affected models.

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Costs of Compliance

    We estimate that 52 airplanes of U.S. registry would be affected by 
this AD.
    The AFM revision that is currently required by AD 2000-24-03, and 
retained in this proposed 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 proposed 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 proposed 
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 proposed 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.
    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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    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 regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.
