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:

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 


cprice-sewell on DSK8KYBLC1PROD with NOTICES
Federal Register / Vol. 75, No. 4 / Thursday, January 7, 2010 / Rules and Regulations 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 

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] 

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. 

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

AGENCY: Federal Aviation

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is revising an 

existing airworthiness directive (AD), 

which applies to certain Model 747– 

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.
