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:

SUPPLEMENTARY INFORMATION:
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
[[Page 905]]
tests (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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
2009-21-08, Amendment 39-16047 74 FR 57561, November 9, 2009), and
adding the following new AD:
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

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

dated June 30, 2005, of PIAGGIO AERO PIAGGIO P.180 AVANTI II

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
