SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: 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 Sarjapur Nagarajan, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329– 4145; fax: (816) 329–4090.

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 Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] cprice-sewell on DSK8KYBLC1PROD with NOTICES 2. The FAA amends § 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. VerDate Nov<24>2008 15:23 Jan 06, 2010 Jkt 220001 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 PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 905 501 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.

ACTION: Final rule; request for comments. SUMMARY: The FAA is revising an existing airworthiness directive (AD), which applies to certain Model 747– VerDate Nov<24>2008 15:23 Jan 06, 2010 Jkt 220001 PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 Date 400, –400D, and –400F series airplanes. That AD currently requires revising the FAA-approved maintenance program by incorporating new airworthiness limitations (AWLs) for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. That AD also requires phasing in certain repetitive AWL inspections, and repair if necessary. This AD clarifies the intended effect of the AD on spare and on-airplane fuel tank system components. This AD results from a design review of the fuel tank systems. We are issuing this AD to prevent the potential for ignition sources inside fuel tanks caused by latent failures, alterations, repairs, or maintenance actions, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Model 
PIAGGIO P-180 Airplanes

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

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.

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,

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
