End Further Info End Preamble Start Supplemental 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.
