Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0169, dated August 17, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain 328 Support 
Services GmbH Model 328-100 and Model 328-300 airplanes. The MCAI 
states:

    Occurrences of broken bonding wires of the fuel line clamps have 
been reported on Dornier 328-100 and Dornier 328-300 aeroplanes 
equipped with fuel line clamps Part Number (P/N) 14C02-10A, or P/N 
14C02-12A, or P/N 14C02-16A. The affected fuel line clamps have been 
installed in accordance with the instructions of SB-328-28-490 or 
SB-328J-28-241 to reduce occurrences of fuel line chafing.
    The results of the investigation did not identify design 
deficiency or production failure of the fuel line clamps. It is 
assumed that the chafing and breaking of the bonding wires are 
caused either by excessive vibration, misalignment, excessive 
installation tolerances or mistakes on installation or a combination 
* * * thereof.
    This condition, if not detected and corrected, could lead to the 
loss of bonding function and, in combination with a lightning 
strike, create a source of ignition in a fuel tank, possibly 
resulting in a fire or explosion and consequent loss of the 
aeroplane.
    To address this unsafe condition, 328 Support Services issued 
Alert Service Bulletin ASB-328-28-041 for Dornier 328-100 aeroplanes 
and ASB-328J-28-018 for Dornier 328-300 aeroplanes respectively 
(hereafter referred to collectively as `the applicable ASB' in this 
[EASA] AD) providing inspection instructions.
    For the reason stated above, this [EASA] AD requires a one-time 
inspection of the fuel line clamps [for discrepancies including 
damaged, worn, or missing bonding wires, and chafing or incorrect 
alignment of jet pumps, connection parts, and fuel lines] and, 
depending on findings, replacement. This [EASA] AD also requires the 
reporting of all inspection results to the design approval holder.
    This [EASA] AD is considered an interim action and further 
[EASA] AD action may follow.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9568.

Related Service Information Under 1 CFR Part 51

    328 Support Services GmbH issued Alert Service Bulletin ASB-328J-
28-018, Revision 1, dated October 13, 2016; and Alert Service Bulletin 
ASB-328-28-041, Revision 1, dated October 13, 2016. The service 
information describes a one-time inspection of the fuel line clamps, 
and replacement of any clamps with worn or missing bonding wires. These 
documents are distinct since they apply to different airplane models.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of

[[Page 3218]]

Design Authority, we have been notified of the unsafe condition 
described in the MCAI and service information referenced above. We are 
proposing this AD because we evaluated all pertinent information and 
determined an unsafe condition exists and is likely to exist or develop 
on other products of these same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 35 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection............................  8 work-hours x $85 per                $0            $680         $23,800
                                         hour = $680.
Reporting.............................  1 work-hour x $85 per                  0              85           2,975
                                         hour = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of airplanes that might need 
these replacements.

                                               On-Condition Costs

----------------------------------------------------------------------------------------------------------------
Replacement of discrepant clamps    Up to 1 work-hour x    Up to $560................  Up to $645.
 on Model 328-100 airplanes.         $85 per hour = $85.
Replacement of discrepant clamps    Up to 1 work-hour x    Up to $588................  Up to $673.
 on Model 328-300 airplanes.         $85 per hour = $85.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this proposed AD 
is 2120-0056. The paperwork cost associated with this proposed AD has 
been detailed in the Costs of Compliance section of this document and 
includes time for reviewing instructions, as well as completing and 
reviewing the collection of information. Therefore, all reporting 
associated with this proposed AD is mandatory. Comments concerning the 
accuracy of this burden and suggestions for reducing the burden should 
be directed to the FAA at 800 Independence Ave. SW., Washington, DC 
20591, ATTN: Information Collection Clearance Officer, AES-200.

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 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 this 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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
