Airworthiness Directives; Piaggio Aero Industries S.p.A. 
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 
certain Piaggio Aero Industries S.p.A. Model P-180 airplanes. 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 event of in-flight baggage door opening occurred on an in-
service aeroplane due to a defective locking mechanism or 
installation thereof; the BAG DOOR warning light went on properly 
before the event, but was ignored by the pilot, who misinterpreted 
it as a false warning.
    NOTE: False in-service BAG DOOR warnings had occurred on other 
P.180 aeroplanes, and Piaggio Aero Industries (PAI) had issued 
Service Bulletin (SB) No. 80-0223 revision 1 to improve the 
installation of the baggage door warning microswitch and to modify 
the locking mechanism if necessary.
    This condition, if not detected and corrected, could lead to in-
flight detachment of the door, which could hit and damage the left 
propeller and/or the vertical or horizontal stabilizer, possibly 
resulting in loss of control of the aeroplane, or in injuries to 
persons or damage to property on the ground.

Instances of the baggage door open light illuminating have occurred 
when the baggage door was not open. This condition, if not corrected, 
could result in the pilot disregarding a valid warning. 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 November 14, 
2011.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No.: 2011-0132, dated July 12, 2011 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    One event of in-flight baggage door opening occurred on an in-
service aeroplane due to a defective locking mechanism or 
installation thereof; the BAG DOOR warning light went on properly 
before the event, but was ignored by the pilot, who misinterpreted 
it as a false warning.
    NOTE: false in-service BAG DOOR warnings had occurred on other 
P.180 aeroplanes, and Piaggio Aero Industries (PAI) had issued 
Service Bulletin (SB) No. 80-0223 revision 1 to improve the 
installation of the baggage door warning microswitch and to modify 
the locking mechanism if necessary.
    This condition, if not detected and corrected, could lead to in-
flight detachment of the door, which could hit and damage the left 
propeller and/or the vertical or horizontal stabilizer, possibly 
resulting in loss of control of the aeroplane, or in injuries to 
persons or damage to property on the ground.
    This AD requires an inspection of the locking mechanism of the 
baggage door and its proper adjustment, in accordance with PAI SB 
No. 80-0289 revision 1; if baggage door lockpins do not reach the 
correct engagement, or false BAG DOOR warnings were reported by 
flight crew, this AD requires also a modification of the door 
mechanism in accordance with PAI SB No. 80-0223 revision 1.

Instances of the baggage door open light illuminating have occurred 
when the baggage door was not open. This condition, if not corrected, 
could result in the pilot disregarding a valid warning. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Piaggio Aero Industries S.p.A. has issued Service Bulletin No. 80-
0223,

[[Page 60397]]

Revision 1, dated July 31, 2009; and Mandatory Service Bulletin No. 80-
0289, Revision 1, dated January 11, 2011. 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 102 products of U.S. 
registry. We also estimate that it would take about 29 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $4,482 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $708,594, or $6,947 per product.

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.


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-2011-1040; 
Directorate Identifier 2011-CE-029-AD.

Comments Due Date

    (a) We must receive comments by November 14, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Piaggio Aero Industries S.p.A. P-180 
Airplane Model P-180 airplanes, serial numbers affected 1002 and 
1004 through 1189, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 52: Doors.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    One event of in-flight baggage door opening occurred on an in-
service aeroplane due to a defective locking mechanism or 
installation thereof; the BAG DOOR warning light went on properly 
before the event, but was ignored by the pilot, who misinterpreted 
it as a false warning.
    NOTE: false in-service BAG DOOR warnings had occurred on other 
P.180 aeroplanes, and Piaggio Aero Industries (PAI) had issued 
Service Bulletin (SB) No. 80-0223 revision 1 to improve the 
installation of the baggage door warning microswitch and to modify 
the locking mechanism if necessary.
    This condition, if not detected and corrected, could lead to in-
flight detachment of the door, which could hit and damage the left 
propeller and/or the vertical or horizontal stabilizer, possibly 
resulting in loss of control of the aeroplane, or in injuries to 
persons or damage to property on the ground.
    This AD requires an inspection of the locking mechanism of the 
baggage door and its proper adjustment, in accordance with PAI SB 
No. 80-0289 revision 1; if baggage door lockpins do not reach the 
correct engagement, or false BAG DOOR warnings were reported by 
flight crew, this AD requires also a modification of the door 
mechanism in accordance with PAI SB No. 80-0223 revision 1.

Instances of the baggage door open light illuminating have occurred 
when the baggage door was not open. This condition, if not 
corrected, could result in the pilot disregarding a valid warning.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) If false in-flight BAG DOOR indications have occurred, 
within 165 hours time-in-service (TIS) after the effective date of 
this AD or within the next 60 days after the effective date of this 
AD, whichever occurs first, do the following actions:
