ACTION: Final rule; correction.

-----------------------------------------------------------------------

[[Page 36981]]

SUMMARY: The FAA is correcting an airworthiness directive (AD) that 
published in the Federal Register. That AD applies to the products 
listed above. The AD number in the preamble on the first page of the AD 
is incorrect. This document corrects that error. In all other respects, 
the original document remains the same.

DATES: This final rule is effective June 24, 2011. The effective date 
for AD 2011-09-51 remains May 31, 2011.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the regulatory evaluation, 
any comments received, and other information. The address for the 
Docket Office (phone: 800-647-5527) is Document Management Facility, 
U.S. Department of Transportation, Docket Operations, M-30, West 
Building Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., 
Washington, DC 20590.

SUPPLEMENTARY INFORMATION: Airworthiness Directive 2011-09-51, 
Amendment 39-16697 (76 FR 27872, May 13, 2011), currently requires an 
inspection and functional test of the valves and drain holes in the 
fuselage and requires sending a report of the results to Piaggio. If 
the valves and drain holes are found to not drain properly and where no 
additional drain holes have been drilled, then there is a requirement 
to drill additional drain holes.
    As published, the AD number specified in the preamble section of 
the first page is incorrect.
    No other part of the preamble or regulatory information has been 
changed; therefore, only the changed portion of the final rule is being 
published in the Federal Register.
    The effective date of AD 2011-09-51 remains May 31, 2011.

Correction of Non-Regulatory Text

    In the Federal Register of May 13, 2011, AD 2011-09-51, Amendment 
39-16697, on page 27872, in the 3rd column, on line 3 of the agency 
identification number section of the preamble of AD 2011-09-51, the AD 
number is incorrectly referenced as AD 2011-10-16. This correction 
changes that AD number to AD 2011-09-51.

    Issued in Kansas City, Missouri, on June 20, 2011.

Packet generated 2026-08-18 08:59 UTC.

This packet is not an airworthiness determination and not legal or maintenance advice. AircraftDirectives reproduces official records and condenses their wording for easier reading. It does not decide, certify or imply whether any aircraft, engine, appliance or part is airworthy, compliant, affected by this directive, or eligible for return to service. No inspection, approval, or determination of any kind is performed or implied by this document.

Section 1 is a reading aid, not the rule. It is our own plain-language condensation, written to help a reader find the relevant directive quickly. It is NOT a substitute for the regulation, it may omit conditions, exceptions, compliance times, alternative methods of compliance (AMOCs) and applicability limits, and it has no legal force whatsoever. Only the official text governs. Where Section 1 and Section 2 differ in any respect, Section 2 - and the official source it was retrieved from - controls absolutely.

Responsibility remains with the owner/operator. Under 14 CFR §91.403 and §91.417 the owner or operator is responsible for maintaining airworthiness and for required records; under §39.7 no person may operate a product to which an airworthiness directive applies except in accordance with that directive. Determining applicability to a specific serial number and configuration, and performing or supervising any required action, is the responsibility of the owner/operator and appropriately certificated personnel.

Accuracy and currency. Section 2 was retrieved at the time stamped above and is reproduced without edit; Federal Register material is a work of the United States Government. Directives are amended, corrected and superseded over time, and this sheet is a snapshot, not a live record - it does not update after printing. Re-check the official sources before acting on it. This packet is provided without warranty of any kind, express or implied, including fitness for a particular purpose. We do not sell parts and have no commercial interest in any action a directive may require.

AircraftDirectives · AD 2011-09-51 · Section 1 is our plain-language reading aid; Section 2 is the official Federal Register text and controls where the two differ. Not an airworthiness determination — 14 CFR §91.403 / §91.417 responsibility remains with the owner/operator. Retrieved 2026-08-18 08:59 UTC.
