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

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to all Piaggio Aero Industries S.p.A. (Piaggio) Model P-180 
airplanes. This AD 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 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. This AD is the result of mandatory continuing airworthiness 
information (MCAI) issued by the airworthiness authority for Italy. 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 March 8, 2003.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulations as of March 
8, 2003.

ADDRESSES: You may get the service information referenced in this AD 
from Piaggio Aero Industries S.p.A, Via Cibrario 4, 16154 Genoa, Italy;

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD? The Ente Nazionale per l' 
Aviazione Civile (ENAC), which is the airworthiness authority for 
Italy, recently notified FAA that an unsafe condition may exist on all 
Piaggio Model P-180 airplanes. The ENAC reports an incident of a ground 
fire on the left-hand engine nacelle of one of the affected airplanes. 
Investigation revealed that the fire was caused by a cracked crossfeed 
valve that had leaked fuel.
    Further analysis led the ENAC to determine that the part number (P/
N) EM484-3 valve was part of a manufacturing batch of nonconforming 
valves. This batch incorporates serial numbers 148 through 302 of these 
P/N EM484-3 valves. These valves can be utilized as either firewall 
shutoff or crossfeed valves.
    What is the potential impact if FAA took no action? If these valves 
are not removed from service, they could develop cracks and leak fuel. 
This could result in an engine fire.
    Has FAA taken any action to this point? We issued a proposal to 
amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to 
include an AD that would apply to all Piaggio Model P-180 airplanes. 
This proposal was published in the Federal Register as a notice of 
proposed rulemaking (NPRM) on November 13, 2002 (67 FR 68782). The NPRM 
proposed to require you to inspect and determine whether any firewall 
shutoff or crossfeed valve with a serial number in a certain range is 
installed and would require you to replace any valve that has a serial 
number within this range. The NPRM would allow the pilot to check the 
logbook and would not require the inspection and replacement 
requirements if the check showed that one of these valves was 
definitely not installed.
    Was the public invited to comment? The FAA encouraged interested 
persons

[[Page 5816]]

to participate in the making of this amendment. We did not receive any 
comments on the proposed rule or on our determination of the cost to 
the public.

FAA's Determination

    What is FAA's final determination on this issue? After careful 
review of all available information related to the subject presented 
above, we have determined that air safety and the public interest 
require the adoption of the rule as proposed except for minor editorial 
corrections. We have determined that these minor corrections:
    [sbull] Provide the intent that was proposed in the NPRM for 
correcting the unsafe condition; and
    [sbull] Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Cost Impact

    How many airplanes does this AD impact? We estimate that this AD 
affects 22 airplanes in the U.S. registry.
    What is the cost impact of this AD on owners/operators of the 
affected airplanes? We estimate the following costs to accomplish the 
inspection:

----------------------------------------------------------------------------------------------------------------
                                                                                 Total cost per   Total cost on
                  Labor cost                              Parts cost                airplane      U.S. operators
----------------------------------------------------------------------------------------------------------------
2 workhours x $60 per hour = $120............  Not applicable.................             $120          $2,640.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to accomplish the replacement/
modification:

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

                                    charge.
------------------------------------------------------------------------

Compliance Time of this AD

    What will be the compliance time of this AD? The inspection 
compliance time of this AD is ``within the next 30 days after the 
effective date of the 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, 
we believe that a compliance time of 30 days will:
    [sbull] Ensure that the unsafe condition does not go undetected for 
a long period of time on the affected airplanes; and
    [sbull] Not inadvertently ground any of the affected airplanes.

Regulatory Impact

    Does this AD impact various entities? The regulations adopted 
herein 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, it is determined that this final rule does not 
have federalism implications under Executive Order 13132.
    Does this AD involve a significant rule or regulatory action? For 
the reasons discussed above, I certify that this action (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. A copy 
of the final evaluation prepared for this action is contained in the 
Rules Docket. A copy of it may be obtained by contacting the Rules 
Docket at the location provided under the caption ADDRESSES.
