Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Airplanes

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.

SUPPLEMENTARY INFORMATION: Back to Top

Discussion Back to Top

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 Back to Top

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 Back to Top

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 Back to Top

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 Back to Top

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 Back to Top

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 Back to Top

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 Back to Top

We estimate that this AD affects 102 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs Back to Top
Action Labor cost Parts cost Cost per product Cost on U.S. operators
Determination/Inspection .5 work-hours × $85 per hour = $42.50 N/A $42.50 $4,335

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:

On-Condition Costs Back to Top
Action Labor cost Parts cost Cost per product
Replacement of affected firewall shutoff and crossfeed valves 29 work-hours × $85 per hour = $2,465 $4,482 $6,947

Authority for This Rulemaking Back to Top

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 Back to Top

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.

List of Subjects in 14 CFR Part 39 Back to Top

Adoption of the Amendment Back to Top

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:

begin regulatory text

PART 39—AIRWORTHINESS DIRECTIVES Back to Top

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

Authority:

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

§ 39.13 [Amended]

2.The FAA amends § 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 R1PIAGGIO AERO INDUSTRIES S.p.A: Amendment 39-17249; Docket No. FAA-2012-1181; Directorate Identifier 2003-CE-030-AD.

(a) Effective Date Back to Top

This AD is effective November 14, 2012.

(b) Affected ADs Back to Top

This AD revises AD 2003-17-03, Amendment 39-13277 (68 FR 50693, August 22, 2003).

(c) Applicability Back to Top

(1) This AD applies to PIAGGIO AERO INDUSTRIES S.p.A Model P-180 airplanes, all serial numbers, that are:

(i) certificated in any category; and

(ii) equipped with a firewall shutoff or crossfeed valve that is identified in the Effectivity table of PIAGGIO Aero Industries S.p.A. Service Bulletin (SB) No. ASB80-0191, dated February 27, 2003.

(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 Back to Top

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

(e) Unsafe Condition Back to Top

This AD was prompted by a report of 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. We are issuing this AD to clarify the affected parts required to correct the unsafe condition on these products.

(f) Compliance Back to Top

Comply with this AD within the compliance times specified, unless already done.

(g) Records Check Back to Top

(1) Within 5 days after September 3, 2003 (the effective date of AD 2003-17-03 (68 FR 50693, August 22, 2003)), check the maintenance records to determine whether a firewall shutoff or crossfeed valve that is affected by this AD is installed. The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may perform this check.

(2) If, by checking the maintenance records, the owner/operator can definitely show that no affected firewall shutoff or crossfeed valve is installed, then the inspection requirement of paragraph (h) of this AD and the replacement requirement of paragraph (i) of this AD do not apply. You must make an entry into the aircraft records that shows compliance with these portions of the AD in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).

(h) Inspection Back to Top

Within 5 days after September 3, 2003 (the effective date of AD 2003-17-03 (68 FR 50693, August 22, 2003)), inspect the three firewall shutoff and crossfeed valves to determine whether they incorporate a serial number as referenced in the Effectivity table of PIAGGIO Aero Industries S.p.A. SB No. ASB80-0191, dated February 27, 2003.

(i) Replacement/Modification Back to Top

If any of the firewall shutoff or crossfeed valves that are referenced in the Effectivity table of PIAGGIO Aero Industries S.p.A.
