ACTION: Airworthiness directives:
DOCUMENT ACTION: Final rule; Removal.
Airworthiness Directives; Industrie Aeronautiche e Meccaniche Model Piaggio P-180 Airplanes
EFFECTIVE DATES: This removal is effective January 2, 2001.
This amendment removes Airworthiness Directive (AD) 2000-03- 19, which currently applies to all Industrie Aeronautiche e Meccaniche (I.A.M.) Model Piaggio P180 airplanes that are equipped with pneumatic deicing boots. AD 20000319 requires revising the Airplane Flight Manual (AFM) to include requirements for activating the airframe pneumatic deicing boots. Since FAA issued AD 20000319, I.A.M. has shown the language currently included in the AFM and the airplane configuration are satisfactory to address the conditions identified in AD 20000319. Therefore, this action removes AD 20000319.
Industrie Aeronautiche e Meccaniche,
Has FAA taken any action to this point? Reports of inflight incidents and an accident (on airplanes other than I.A.M. Piaggio Model P180 airplanes), that occurred in icing conditions where the airframe pneumatic deicing boots were not activated, caused FAA to issue AD 20000319, Amendment 3911578 (65 FR 7717, February 16, 2000). This AD currently requires revising the Airplane Flight Manual (AFM) to include requirements for activating the airframe pneumatic deicing boots on all I.A.M. Model Piaggio P180 airplanes that are equipped with pneumatic deicing boots.
The actions of AD 20000319 are intended to assure that flightcrews have the information necessary to activate the pneumatic wing and tail deicing boots at the first signs of ice buildup. Without this information, flightcrews could experience reduced control of the aircraft because of adverse aerodynamic effects of ice adhering to the airplane before the first deicing cycle.
After issuing AD 20000319, I.A.M. asserted that the wording within the AFM (without the revision) and the configuration of the airplane deice system provide for safe operation of the affected airplanes. Therefore, I.A.M. requests FAA remove the final rule because the AD requirements are redundant. The FAA has since evaluated all information related to the subject matter of AD 20000319 and has determined the actions included in AD 20000319 are redundant and not necessary.
We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to remove AD 20000319. This proposal was published in the Federal Register as a Notice of proposed rulemaking (NPRM); removal of final rule on October 19, 2000 (65 FR 62650).
Was the public invited to comment? Interested persons were afforded an opportunity to participate in the making of the action. No comments were received on the proposed rule.
What is FAA's Final Determination on this Issue? Based on the above information, FAA has determined there is no need for AD 20000319 and that it should be removed.
This action removes AD 20000319. Removal of AD 20000319 will not preclude FAA from issuing another action in the future, nor will it commit us to any course of action in the future.
Does this action involve a significant rule or regulatory action? Since this action only removes an AD, it is not an AD and, therefore, is not covered under Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).
