AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

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). 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by September 21, 

2009. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued AD 2009–0129, 

dated June 19, 2009 (referred to after 

this as ‘‘the MCAI’’), to correct an unsafe 

condition for the specified products. 

The 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 leakage of the steering manifold, 

the replacement of the steering 

manifold. 

Relevant Service Information 

Piaggio Aero Industries S.p.A. has 

issued: 

• Service Bulletin (Mandatory) N. 80– 

0249, rev. 1, dated May 27, 2009; 

• (for S/N 1004 through 1104) Piaggio 

Aero Piaggio P.180 Avanti Maintenance 

Manual, Report No. 9066, 32–50–00, 

revised June 16, 2008; and 

• (for S/N 1105 and greater) Piaggio 

Aero Piaggio P.180 Avanti II 

Maintenance Manual, Report No. 180– 

MAN–0200–01105, 32–50–00, revised 

December 19, 2008. 

The actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of the Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with this State of 

Design Authority, they have notified us 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences between this Proposed AD 

and the MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

We estimate that this proposed AD 

will affect 63 products of U.S. registry. 

We also estimate that it would take 

about 8 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $80 per work-hour. 

Based on these figures, we estimate 

the cost of the proposed AD on U.S. 

operators to be $40,320, or $640 per 

product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 16 work-hours and require parts 

costing $0, for a cost of $1,280 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

Authority for this Rulemaking 

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 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would 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 this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 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 adding 

the following new AD: 

Piaggio Aero Industries S.p.A.: Docket No. 

FAA–2009–0699; Directorate Identifier 

2009–CE–042–AD. 

Comments Due Date 

(a) We must receive comments by 

September 21, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Model 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 

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 the 

effective date of this AD or within the next 

100 hours time-in-service (TIS) after the 

effective date of this AD, whichever occurs 

first, and repetitively thereafter at intervals 

not to exceed every 165 hours TIS, do a

27, 2009. 

(3) If during any inspection required in 

paragraphs (f)(1) and (f)(2) of this AD a NLG 

steering manifold does not pass the 

functional tests, using the compliance times 

in the accomplishment instructions of

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: There have been four 

reports of loose or detached main 

landing gear torque link apex pin 

locking plate and the locking plate 

retainer bolt. This condition could 

result in torque link apex pin 

disengagement, heavy vibration during 

landing, damage to main landing gear 

components and subsequent main 

landing gear collapse. 

The proposed AD would require 

actions that are intended to address the 

unsafe condition described in the MCAI.
