Airworthiness Directives; Piaggio Aero Industries S.p.A. Model P-
180 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This document supersedes Airworthiness Directive (AD) 2003-03-
14, which applies to all PIAGGIO AERO INDUSTRIES S.p.A. (PIAGGIO) Model 
P-180 airplanes. AD 2003-03-14 currently requires you to inspect and 
determine whether any firewall shutoff or crossfeed valve with a serial 
number in a certain range is installed and requires you to replace or 
modify any valve that has a serial number within this range. The 
modification consisted of reworked valves that were re-identified with 
an ``A'' at the end of the serial number. AD 2003-03-14 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. Since AD 2003-03-14 became effective, the 
Federal Aviation Administration (FAA) has found that the valve 
manufacturer was not correctly incorporating the modification on 
reworked valves. Consequently, the installation of modified fuel valves 
installed per AD 2003-03-14 could allow the unsafe condition to remain 
on the affected airplanes. This AD would require you to replace any 
firewall shutoff or crossfeed valve with a serial number in a certain 
range even if it has been modified per AD 2003-03-14. The actions 
specified by this AD are intended to prevent a faulty firewall shutoff 
or crossfeed valve from developing cracks and leaking fuel. This could 
result in an engine fire.

DATES: This AD becomes effective on September 3, 2003.
    The Director of the Federal Register approved the incorporation by 
reference

of certain publications listed in the regulation as of September 3, 
2003.

SUPPLEMENTARY INFORMATION:

Discussion

    Has FAA taken any action to this point? A ground fire on the left-
hand engine nacelle caused by a cracked crossfeed valve that had leaked 
fuel on a PIAGGIO Model P-180 airplane caused FAA to issue AD 2003-03-
14, Amendment 39-13038 (68 FR 5815, February 5, 2003).
    AD 2003-03-14 currently requires you to inspect and determine 
whether any firewall shutoff or crossfeed valve with a serial number in 
a certain range is installed and requires you to replace or modify any 
valve that has a serial number within this range. The modification 
consisted of reworked valves that were re-identified with an ``A'' at 
the end of the serial number. 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.
    What has happened since AD 2003-03-14 to initiate this proposed 
action? The Ente Nazionale per l' Aviazione Civile (ENAC), which is the 
airworthiness authority for Italy, recently notified FAA of the need to 
change AD 2003-03-14. The ENAC reports that the valve manufacturer was 
not correctly incorporating the modification on reworked valves and 
that these modified valves need to be replaced.
    Is there service information that applies to this subject? PIAGGIO 
has issued Service Bulletin No. ASB80-0191, dated February 27, 2003. 
Included as part of this service bulletin is Electromech Technologies 
SB 484-3 AB, dated February 18, 2003.
    What are the provisions of this service information? The service 
information includes:
    --A list of those Electromech part number (P/N) fuel valves that 
are affected by the unsafe condition;
    --Procedures for determining whether one of the affected fuel 
valves is installed; and
    --Instructions for replacing or modifying any affected fuel valve.
    What action did the ENAC take? The ENAC classified this service 
bulletin as mandatory and issued Italian RAI-AD 2003-119, dated April 
3, 2003, in order to ensure the continued airworthiness of these 
airplanes in Italy.
    Was this in accordance with the bilateral airworthiness agreement? 
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 (14 CFR 21.29) and the 
applicable bilateral airworthiness agreement.
    Pursuant to this bilateral airworthiness agreement, the ENAC has 
kept FAA informed of the situation described above.

The FAA's Determination and an Explanation of the Provisions of This AD

    What has FAA decided? The FAA has examined the findings of the 
ENAC; reviewed all available information, including the service 
information referenced above; and determined that:
    --The unsafe condition referenced in this document exists or could 
develop on other PIAGGIO Model P-180 airplanes of the same type design 
that are on the U.S. registry;
    --The fuel valves modified per AD 2003-03-14 should also be 
replaced;
    --The actions specified in the previously-referenced service 
information should be accomplished on the affected airplanes; and
    --AD action should be taken in order to correct this unsafe 
condition.
    What does this AD require? This AD supersedes AD 2003-03-14 with a 
new AD that requires you to replace any firewall shutoff or crossfeed 
valve with a serial number in a certain range even if it has been 
modified per AD 2003-03-14.
    How does the revision to 14 CFR part 39 affect this AD? On July 10, 
2002, FAA published a new version of 14 CFR part 39 (67 FR 47997, July 
22, 2002), which governs FAA's AD system. This regulation now includes 
material that relates to special flight permits, alternative methods of 
compliance, and altered products. This material previously was included 
in each individual AD. Since this material is included in 14 CFR part 
39, we will not include it in future AD actions.
    Will I have the opportunity to comment prior to the issuance of the 
rule? Because the unsafe condition described in this document could 
result in an engine fire, we find that notice and opportunity for 
public prior comment are impracticable. Therefore, good cause exists 
for making this amendment effective in less than 30 days.

Comments Invited

    How do I comment on this AD? Although this action is in the form of 
a final rule and was not preceded by notice and opportunity for public 
comment, FAA invites your comments on the rule. You may submit whatever 
written data, views, or arguments you choose. You need to include the 
rule's docket number and submit your comments to the address specified 
under the caption ADDRESSES. We will consider all comments received on 
or before the closing date specified above. We may amend this rule in 
light of comments received. Factual information that supports your 
ideas and suggestions is extremely helpful in evaluating the 
effectiveness of this AD action and determining whether we need to take 
additional rulemaking action.
    Are there any specific portions of this AD I should pay attention 
to? We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. You may view all comments we receive 
before and after the closing date of the rule in the Rules Docket. We 
will file a report in the Rules Docket that summarizes each FAA contact 
with the public that concerns the substantive parts of this AD.

[[Page 50695]]

    How can I be sure FAA receives my comment? If you want us to 
acknowledge the receipt of your comments, you must include a self-
addressed, stamped postcard. On the postcard, write ``Comments to 
Docket No. 2003-CE-30-AD.'' We will date stamp and mail the postcard 
back to you.

Compliance Time of This AD

    Why is the compliance time presented in calendar time instead of 
hours time-in-service (TIS)? The compliance of this AD is presented in 
calendar time instead of hours TIS because the affected shutoff and 
crossfeed valves are unsafe as a result of a quality control problem. 
The problem has the same chance of existing on an airplane with 50 
hours TIS as it would for an airplane with 1,000 hours TIS. Therefore, 
FAA has determined that the compliance time of this AD should be 
presented in calendar time.

Regulatory Impact

    Does this AD impact various entities? These regulations 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. 
Therefore, FAA has determined that this final rule does not have 
federalism implications under Executive Order 13132.
    Does this AD involve a significant rule or regulatory action? We 
have determined that this regulation is an emergency regulation that 
must be issued immediately to correct an unsafe condition in aircraft, 
and is not a significant regulatory action under Executive Order 12866. 
It has been determined further that this action involves an emergency 
regulation under DOT Regulatory Policies and Procedures (44 FR 11034, 
February 26, 1979). If it is determined that this emergency regulation 
otherwise would be significant under DOT Regulatory Policies and 
Procedures, a final regulatory evaluation will be prepared and placed 
in the Rules Docket (otherwise, an evaluation is not required). A copy 
of it, if filed, may be obtained from the Rules Docket.
