DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. 99-CE-53-AD]
RIN 2120-AA64


Airworthiness Directives; The Cessna Aircraft Company Models 425 
and 441 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 Cessna Aircraft Company (Cessna) Models 
425 and 441 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 Cessna airplanes) that occurred in 
icing conditions where the airframe pneumatic deicing boots were not 
activated. Cessna 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-53-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 
Cessna Models 425 and 441 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 55184). 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 Cessna. 
Our analysis and disposition of this comment follow:

Comment Disposition

What Is the Commenter's Concern?

    Cessna provides information 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, Cessna requests that FAA 
withdraw the NPRM.

What Is FAA's Response to the Concern?

     After evaluating the information that Cessna 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 Cessna 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-53-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).

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Safety.

The Withdrawal

    Accordingly, FAA withdraws the notice of proposed rulemaking, 
Docket No. 99-CE-53-AD, published in the Federal Register on October 
12, 1999 (64 FR 55184).

    Issued in Kansas City, Missouri, on August 23, 2000.
