Proposed rule; Withdrawal.
This document withdraws a notice of proposed rulemaking (NPRM) that would have applied to all Pilatus Britten-Norman Limited (Britten-Norman) Models BN-2T and BN-2T-4R airplanes. The proposed AD would have required you to revise the Airplane Flight Manual (AFM) to include requirements for activation of the airframe pneumatic deicing boots. The proposed AD was the result of reports of in-flight incidents and an accident (on airplanes other than the referenced Britten-Norman airplanes) that occurred in icing conditions where the airframe pneumatic deicing boots were not activated. Britten-Norman has demonstrated that the language currently included in the AFM is adequate to address the conditions identified in the proposed AD for these airplanes. Therefore, AD action is not necessary to address the conditions on these airplanes and we are withdrawing the NPRM.

What action has FAA taken to date? We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to all Britten-Norman Models BN-2T and BN-2T-4R airplanes that are equipped with pneumatic deicing boots. The proposal was published in the Federal Register as an NPRM on October 8, 1999 (64 FR 54829). The NPRM proposed to require revising the Limitations Section of the AFM to include requirements for activation of pneumatic deicing boots at the first sign of ice accumulation on the airplane.
Was the public invited to comment? The FAA invited interested persons to participate in the making of this amendment. We received one comment on the proposed AD. Our analysis and disposition of this comment follow:
What is the commenter's concern? Britten-Norman believes that the present wording within the AFM has provided for safe operation of the affected airplanes for many years. Therefore, Britten-Norman states that FAA should withdraw the NPRM because the requirements would be redundant.
What is FAA's response to the concern? After reviewing the current wording in the Britten-Norman AFM, we agree that the actions included in the NPRM are not necessary. We will withdraw the NPRM per the Britten-Norman request.
The FAA's Determination
What is FAA's final determination on this issue? Based on the above information, we have determined that there is no need for the NPRM, Docket No. 99-CE-35-AD, and that we should withdraw it.
Withdrawal of this NPRM does not prevent us from issuing another notice in the future, nor will it commit us to any course of action in the future.
Does this AD involve a significant rule or regulatory action? Since this action only withdraws a proposed 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).Start List of Subjects
