SUPPLEMENTARY INFORMATION:

Discussion

    On August 12, 2003, we issued AD 2003-17-03, amendment 39-13277 (68 
FR 50693, August 22, 2003), for certain Piaggio Aero Industries S.p.A. 
Model P-180 airplanes. That AD requires inspection and determination of 
whether any firewall shutoff or crossfeed valve with a serial number in 
a certain range is installed and requires replacement or modifications 
of any valve that has a serial number within this range. This AD allows 
the pilot to check the logbook and does not require the inspection and 
replacement requirement if the check shows that one of these valves is 
definitely not installed.
    That AD resulted from a ground fire on the left-hand engine nacelle 
of one of the affected airplanes caused by a cracked firewall crossfeed 
valve that had leaked fuel. This airplane model is manufactured in 
Italy and is type certificated for operation in the United States under 
the provisions of section 21.29 of the Federal Aviation Regulations. 
The Ente Nazionale per l'Aviazione Civile (ENAC), which is the 
airworthiness authority for Italy, issued Italian RAI-AD 2003-119, 
dated April 3, 2003, in order to ensure the continued airworthiness of 
these airplanes in Italy.
    We issued that AD to prevent a faulty firewall shutoff or crossfeed 
valve from developing cracks and leaking fuel, which could result in an 
engine fire.

Actions Since AD Was Issued

    Since we issued AD 2003-17-03 (68 FR 50693, August 22, 2003), we 
learned that the way the applicability was written includes valves that 
should not be affected and are not included in PIAGGIO Aero Industries 
S.p.A. Service Bulletin No. ASB80-0191, dated February 27, 2003.

Relevant Service Information

    We reviewed PIAGGIO Aero Industries S.p.A. Service Bulletin (SB) 
No. ASB80-0191, dated February 27, 2003; and Electromech Technologies 
SB 484-3 AB, dated February 18, 2003. The service information describes 
procedures for replacing/modifying the firewall and crossfeed valves.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

AD Requirements

    This AD requires the same actions as AD 2003-17-03 (68 FR 50693, 
August 22, 2003), but only affects those firewall shutoff and crossfeed 
valves referenced in PIAGGIO Aero Industries S.p.A. SB No. ASB80-0191, 
dated February 27, 2003.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because the 
current AD includes firewall shutoff and crossfeed valves that should 
not be affected by the required actions. Therefore, we find that notice 
and opportunity for prior public comment are unnecessary and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
the docket number FAA-2012-1181 and directorate identifier 2003-CE-030-
AD at the beginning of your comments. We specifically invite comments 
on the overall regulatory, economic, environmental, and energy aspects 
of this AD. We will consider all comments received by the closing date 
and may amend this AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 102 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

[[Page 67766]]

                                       hour = $42.50.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements/
modifications that would be required based on the results of the 
determination. We have no way of determining the number of aircraft 
that might need these replacements:

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

    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),
    (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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends part 39 of the Federal Aviation 
Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

2. The FAA amends Sec.  39.13 by removing airworthiness directive (AD) 
2003-17-03, Amendment 39-13277 (68 FR 50693, August 22, 2003), and 
adding the following new AD:

2003-17-03 R1 PIAGGIO AERO INDUSTRIES S.p.A: Amendment 39-17249; 
Docket No. FAA-2012-1181; Directorate Identifier 2003-CE-030-AD.

(a) Effective Date

    This AD is effective November 14, 2012.

(b) Affected ADs

    This AD revises AD 2003-17-03, Amendment 39-13277 (68 FR 50693,

    (2) The only difference between the applicability of this AD and 
AD 2003-17-03 (68 FR 50693, August 22, 2003), is that AD 2003-17-03 
applied to firewall shutoff and crossfeed valves that should not 
have been included.
    (i) No further action is necessary if the actions of this AD 
were done in compliance with AD 2003-17-03, Amendment 39-13277 (68 
FR 50693, August 22, 2003).
    (ii) Any firewall shutoff or crossfeed valve that was modified 
per AD 2003-17-03 (68 FR 50693, August 22, 2003), and re-identified 
with an ``A'' at the end of the serial number and is not identified 
in the Effectivity table of PIAGGIO Aero Industries S.p.A. SB No. 
ASB80-0191, dated February 27, 2003, is an airworthy part and is not 
affected by this AD.

 (d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 28: Fuel.

(e) Unsafe Condition

    This AD was prompted by a report of a ground fire on the left-
