Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are clarifying information contained in Airworthiness Directive (AD) 2009-21-08, which applies to PIAGGIO AERO INDUSTRIES S.p.A. (Piaggio) Model PIAGGIO P-180 airplanes. AD 2009-21-08 currently requires repetitive functional tests of the manifold system and replacement of any system that does not pass the functional tests (i.e., movement of the steering system). The language in AD 2009-21-08 incorrectly references not passing the functional tests as “movement of the manifold,” and it should read “movement of the steering system” as specified in the service bulletin. The notice of proposed rulemaking (NPRM) referenced it as specified in the service bulletin. This document incorporates the intent of the action as already proposed in the NPRM. We are issuing this AD to prevent a potentially dangerous veer along the runway. The steering system must be in the `off' position during landing and takeoff (in this case when airspeed is higher than 60 knots) according to the aircraft flight manual limitations.

DATES:

The effective date of this AD is December 14, 2009, which is the same as AD 2009-21-08.

As of December 14, 2009 (74 FR 57561, November 9, 2009), the Director of the Federal Register approved the incorporation by reference of the following documents listed in this AD:

Discussion

On October 7, 2009, we issued AD 2009-21-08, Amendment 39-16047 (74 FR 57561, November 9, 2009), to require repetitive functional tests of the manifold system and replacement of any system that does not pass the functional Start Printed Page 905tests (i.e., movement of the steering system) on Piaggio Model PIAGGIO P-180 airplanes.

The language in AD 2009-21-08 incorrectly references not passing the functional tests as “movement of the manifold,” and it should read “movement of the steering system” as specified in the service bulletin. The NPRM referenced it as specified in the service bulletin. This document incorporates the intent of the action as already proposed in the NPRM.

Consequently, the FAA sees a need to clarify AD 2009-21-08 to assure that the proper criteria are utilized for the required functional test and is revising the AD to incorporate the language discussed above and to add the amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13).

Since this action only clarifies the intent of what was originally proposed in the NPRM, it has no adverse economic impact and imposes no additional burden on any person than was already proposed. Therefore, the FAA has determined that prior notice and opportunity for public comment are unnecessary.

2009-21-08 R1 PIAGGIO AERO INDUSTRIES S.p.A.: Amendment 39-16169; Docket No. FAA-2009-0699; Directorate Identifier 2009-CE-042-AD.

Effective Date

(a) The effective date of this AD is December 14, 2009, which is the same as AD 2009-21-08.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Model PIAGGIO P-180 airplanes, all serial numbers (S/N), certificated in any category.

Subject

(d) Air Transport Association of America (ATA) Code 32: Landing Gear.

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

Some cases of uncommanded steering action were observed, while the steering system was switched off.

A leakage in the Steering Select/Bypass Valve, installed in the Steering Manifold, when closed, is suspected to have caused the uncommanded steering.

If left uncorrected, this condition could lead to a potentially dangerous veer along the runway; in fact, according to the Aircraft Flight Manual limitations, the steering system must be in `off' position during landing and takeoff (in this case when airspeed is higher than 60 knots). For the reasons stated above, this new AD mandates repetitive inspections for leakage of the Nose Landing Gear steering manifold.

The MCAI requires, if any inspection finds internal leakage of the steering manifold, the replacement of the steering manifold.

Actions and Compliance

(f) Unless already done, do the following actions:

(1) Within the next 6 months after December 14, 2009 (the effective date of this AD and AD 2009-21-08) or within the next 100 hours time-in-service (TIS) after December 14, 2009 (the effective date of this AD and AD 2009-21-08), whichever occurs first, and repetitively thereafter at intervals not to exceed every 165 hours TIS, do a functional test of the nose landing gear (NLG) steering manifold. Follow the accomplishment instructions of PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N. 80-0249 (includes CONFIRMATION SLIP), Rev. 1, dated May 27, 2009.

(2) Upon installation of a NLG steering manifold on any airplane, do a functional test of the NLG steering manifold. Repetitively thereafter at intervals not to exceed every 165 hours TIS, do a functional test of the NLG steering manifold. Follow the accomplishment instructions of PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N. 80-0249 (includes CONFIRMATION SLIP), Rev. 1, dated May 27, 2009.

(3) If during any inspection required in paragraphs (f)(1) and (f)(2) of this AD, any manifold system does not pass the functional tests (i.e., movement of the steering system), using the compliance times in the accomplishment instructions of PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N. 80-0249 (includes CONFIRMATION SLIP), Rev. 1, dated May 27, 2009, replace the NLG steering manifold following (for S/N 1004 through 1104) pages 1 through 8 dated March 1, 2006; 201, 202, 204, and 206 through 216, dated June 16, 2008; 203 and 205, dated March 1, 2006; and 501 through 506, dated March 1, 2006, of PIAGGIO AERO PIAGGIO P.180 AVANTI Maintenance Manual, Report No. 9066, 32-50-00, Revision No. D2, revised June 16, 2008; or (for S/N 1105 and greater) pages 1 through 8, dated June 30, 2005; 201, 202, and 207 through 209, dated December 19, 2008; 203 and 205, dated June 30, 2005; 204, 206, and 210 through 216, dated September 14, 2007; and 501 through 506, dated June 30, 2005, of PIAGGIO AERO PIAGGIO P.180 AVANTI II Maintenance Manual, Report No. 180-MAN-0200-01105, 32-50-00, Revision No. A3, revised December 19, 2008.

FAA AD Differences

This AD differs from the MCAI and/or service information as follows: No differences.

Other FAA AD Provisions

(g) The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Sarjapur Nagarajan, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4145; fax: (816) 329-4090.
