Airworthiness Directives; Dornier Model 328-300 Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to all AvCraft Dornier Model 328-300 airplanes. 
That AD currently requires modifying the electrical wiring of the fuel 
pumps; installing insulation at the flow control and shut-off valves, 
and other components of the environmental control system; installing 
markings at fuel wiring harnesses; replacing the wiring harness of the 
auxiliary fuel system with a new wiring harness; and installing 
insulated couplings in the fuel system; as applicable. The existing AD 
also requires revising the Airworthiness Limitations section of the 
Instructions for Continued Airworthiness to incorporate new inspections 
of the fuel tank system. This new AD replaces the flight-hour-based 
threshold for conducting certain initial inspections, with a calendar-
based threshold. This AD results from fuel system reviews conducted by 
the manufacturer. We are issuing this AD to reduce the potential of 
ignition sources inside fuel tanks, which, in combination with 
flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.

DATES: This AD becomes effective April 3, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of April 3, 
2009.
    On September 6, 2005 (70 FR 44046, August 1, 2005), the Director of 
the Federal Register approved the incorporation by reference of certain 
other publications referenced in this AD.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2005-15-16, amendment 
39-14205 (70 FR 44046, August 1, 2005). The existing AD applies to all 
AvCraft Dornier Model 328-300 airplanes. That NPRM was published in the 
Federal Register on August 11, 2008 (73 FR 46569). That NPRM proposed 
to continue to require modifying the electrical wiring of the fuel 
pumps; installing insulation at the flow control and shut-off valves, 
and other components of the environmental control system; installing 
markings at fuel wiring harnesses; replacing the wiring harness of the 
auxiliary fuel system with a new wiring harness; and installing 
insulated couplings in the fuel system; as applicable. That NPRM also 
proposed to continue to require revising the Airworthiness Limitations 
section of the Instructions for Continued Airworthiness to incorporate 
new inspections of the fuel tank system. That NPRM also proposed to 
replace the flight-hour-based threshold for conducting certain initial 
inspections, with a calendar-based threshold.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received 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

    The following table provides the estimated costs for U.S. operators 
to comply with this AD. The average labor rate is $80 per work hour.

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 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.

ignition sources inside fuel tanks, which, in combination with 
flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

    Note 1: This AD requires revisions to certain operator 
maintenance documents to include inspections. Compliance with these 
inspections is required by 14 CFR 91.403(c). For airplanes that have 
been previously modified, altered, or repaired in the areas 
addressed by these inspections, the operator may not be able to 
accomplish the inspections described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (k) of this AD. The request should include a 
description of changes to the required inspections that will ensure 
the continued operational safety of the airplane.
