[Docket No. 99-CE-46-AD]
RIN 2120-AA64


Airworthiness Directives; Raytheon Aircraft Company 90, 99, 100, 
200, 300, 1900, and 2000 Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Proposed rule; withdrawal.

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

SUMMARY: This document withdraws a notice of proposed rulemaking (NPRM) 
that would have applied to all Raytheon Aircraft Company (Raytheon) 90, 
99, 100, 200, 300, 1900, and 2000 series 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 Raytheon 
airplanes) that occurred in icing conditions where the airframe 
pneumatic deicing boots were not activated. Raytheon has demonstrated 
that the design of the affected airplanes, including the language 
currently 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.

ADDRESSES: You may look at information related to this action at the 
Federal Aviation Administration (FAA), Central Region, Office of the 
Regional Counsel, Attention: Rules Docket No. 99-CE-46-AD, 901 Locust, 
Room 506, Kansas City, Missouri 64106, between 8 a.m. and 4 p.m., 
Monday through Friday, except holidays.

FOR FURTHER INFORMATION CONTACT: Mr. Larry E. Werth, Airworthiness 
Directive Coordinator, FAA, Small Airplane Directorate, 901 Locust, 
Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4147;

SUPPLEMENTARY INFORMATION:

Discussion

    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 Raytheon 90, 99, 100, 200, 300, 1900, and 
2000 series airplanes that are equipped with pneumatic deicing boots. 
The proposal was published in the Federal Register as an NPRM on 
October 12, 1999 (64 FR 55188). 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 a 
comment on the proposed AD from Raytheon. Our analysis and disposition 
of this comment follow:

Comment Disposition

    What is the commenter's concern? Raytheon provides data it believes 
demonstrates that the design of the affected airplanes, including the 
language currently in the AFM, is adequate to address the conditions 
identified in the proposed AD for these airplanes. Therefore, Raytheon 
requests that FAA withdraw the NPRM.
    What is FAA's response to the concern? After evaluating the data 
that Raytheon submitted, we have determined that the design of the 
affected airplanes, including the language currently in the AFM, is 
adequate to address the conditions identified in the proposed AD for 
these airplanes. We will withdraw the NPRM per the Raytheon 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-46-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.

Regulatory Impact

    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).
