ACTION:
 
Final rule; request for comments.

SUMMARY:
 
We are revising an existing airworthiness directive (AD) for certain Piaggio Aero


Industries S.p.A. Model P-180 airplanes. That AD currently requires replacement of any firewall


shutoff or crossfeed valve with a serial number in a certain range even if it has been previously


modified. The way the applicability was written includes valves that should not be affected and are


not included in the referenced service information. This AD requires the same actions as the current


AD, but only affects those firewall shutoff valves referenced in the referenced service information.


We are issuing this AD to clarify the affected parts required to correct the unsafe condition on these


products.


DATES:
 
This AD is effective November 14, 2012.


The Director of the Federal Register approved the incorporation by reference of certain other


publications listed in this AD as of September 3, 2003 (68 FR 50693, August 22, 2003).


We must receive any comments on this AD by December 31, 2012.

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.
