Airworthiness Directives; Piaggio Aero Industries S.p.A. P-180 
Airplanes

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:

    One P-180 aircraft experienced a jamming of its longitudinal 
flight control cables. Investigations revealed that its fuselage 
drain holes were plugged, and water was trapped in the lower 
fuselage.
    As a consequence of plugged drain holes, water can accumulate 
and freeze when the aircraft reaches and holds altitudes where 
temperature is below the freezing point. If not corrected this may 
cause the loss of control of the airplane.

    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 May 11, 2007.

ADDRESSES: You may send comments by any of the following methods:
    <bullet> DOT Docket Web Site: Go to http://dms.dot.gov and follow

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. This streamlined process will allow us to adopt 
MCAI

[[Page 18156]]

safety requirements in a more efficient manner and will reduce safety 
risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This proposed AD references the MCAI and related service 
information that we considered in forming the engineering basis to 
correct the unsafe condition. The proposed AD contains text copied from 
the MCAI and for this reason might not follow our plain language 
principles.

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2007-
27532; Directorate Identifier 2007-CE-021-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because of those comments.
    We will post all comments we receive, without change, to http://dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact we 
receive about this proposed AD.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2007-0031, dated February 9, 2007 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products.

    One P-180 aircraft experienced a jamming of its longitudinal 
flight control cables. Investigations revealed that its fuselage 
drain holes were plugged, and water was trapped in the lower 
fuselage.
    As a consequence of plugged drain holes, water can accumulate 
and freeze when the aircraft reaches and holds altitudes where 
temperature is below the freezing point. If not corrected this may 
cause the loss of control of the airplane.

    The MCAI requires:

    * * * Check for proper operation, fuselage drain holes and the 
passenger evaporator drain line and to introduce a temporary 
revision of the Aircraft Maintenance Manual.

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

Piaggio Aero Industries S.p.A. has issued Mandatory Service Bulletin 
SB-80-0220, dated August 8, 2006. 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

    Based on the service information, we estimate that this proposed AD 
would affect about 60 products of U.S. registry. We also estimate that 
it would take about 5 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 $24,000, or $400 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 13 work-hours and require parts costing $125 for a cost of 
$1,165 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

[[Page 18157]]

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.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Piaggio Aero Industries S.P.A.: Docket No. FAA-2007-27532; 
Directorate Identifier 2007-CE-021-AD.

Comments Due Date

    (a) We must receive comments by May 11, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to P-180 airplanes, serial numbers 1004 
through 1112, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 53: 
Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    One P 180 aircraft experienced a jamming of its longitudinal 
flight control cables. Investigations revealed that its fuselage 
drain holes were plugged, and water was trapped in the lower 
fuselage.
    As a consequence of plugged drain holes, water can accumulate 
and freeze when the aircraft reaches and holds altitudes where 
temperature is below the freezing point. If not corrected this may 
cause the loss of control of the airplane.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) At the next scheduled maintenance inspection or 1 month 
after the effective date of the AD, whichever occurs later, and 
repetitively thereafter at intervals not to exceed every 12 months, 
inspect fuselage drain holes and the passenger evaporator drain line 
for proper operation and do all the necessary corrective actions, 
following the accomplishment instructions of the Piaggio Aero 
Industries S.p.A. Mandatory SB-80-0220, dated August 8, 2006.

    Note 1: We have established the repetitive inspection times of 
this AD so that they may coincide with annual inspections.


    Note 2: We encourage you to update your maintenance program by 
inserting the Temporary Revision of the Piaggio P 180 Avanti 
Maintenance Manual (AMM) attached to the Piaggio Aero Industries 
S.p.A. Mandatory SB-80-0220, dated August 8, 2006.

FAA AD Differences

    Note 3: This AD differs from the MCAI and/or service information 
as follows: We have added repetitive inspection requirements in the 
AD to coincide with the Piaggio P 180 Avanti Maintenance Manual 
temporary revision referenced in the Piaggio Aero Industries S.p.A. 
Mandatory Service Bulletin SB-80-0220, dated August 8, 2006.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Staff, FAA, 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, has 
the authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. Before using any approved AMOC on 
any airplane to which the AMOC applies, notify your appropriate 
principal inspector (PI) in the FAA Flight Standards District Office 
(FSDO), or lacking a PI, your local FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, under the provisions of the Paperwork Reduction Act (44 
U.S.C. 3501 et.seq.), the Office of Management and Budget (OMB) has 
approved the information collection requirements and has assigned 
OMB Control Number 2120-0056.
