[Docket No. 92-NM-206-AD]
RIN 2120-AA64


Airworthiness Directives; Gulfstream Model G-IV Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Proposed rule; withdrawal.

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

SUMMARY: This action withdraws a notice of proposed rulemaking (NPRM) 
that proposed a new airworthiness directive (AD), applicable to certain 
Gulfstream Model G-IV series airplanes. That action would have required 
inspection of the data plate on the bottom of the hydraulic brake 
control module (HBCM) to verify the part and serial numbers, and 
replacement of the HBCM, if necessary. Since the issuance of the NPRM, 
the Federal Aviation Administration (FAA) has received new data 
indicating that the proposed actions have been accomplished on all 
affected airplanes; therefore, the previously identified unsafe 
condition no longer exists. Accordingly, the proposed rule is 
withdrawn.

FOR FURTHER INFORMATION CONTACT: Neil Barryman, Aerospace Engineer, 
Systems and Flight Test Branch, ACE-116A, FAA, Small Airplane 
Directorate, Atlanta Aircraft Certification Office, One Crown Center,

(770) 703-6098; fax (770) 703-6097.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to add a new airworthiness 
directive (AD), applicable to certain Gulfstream Model G-IV series 
airplanes, was published in the Federal Register as a Notice of 
Proposed Rulemaking (NPRM) on April 9, 1993 (58 FR 18347). The proposed 
rule would have required inspection of the data plate on the bottom of 
the hydraulic brake control module (HBCM) to verify the part and serial 
numbers, and replacement of the HBCM, if necessary. That action was 
prompted by a landing incident that involved a malfunction of the 
braking system. The proposed actions were intended to prevent a 
malfunction of the braking system, which could lead to reduced 
controllability of the airplane on the ground.

Actions that Occurred Since the NPRM Was Issued

    Since the issuance of that NPRM, Gulfstream has provided evidence 
to the FAA that the actions proposed in the NPRM have been accomplished 
on all affected airplanes (Evidence was provided to the FAA in 
Gulfstream's letter of May 30, 2000, which is filed in the Rules 
Docket.)

FAA's Conclusions

    Upon further consideration, the FAA has determined that, based on 
this evidence, the previously identified unsafe condition no longer 
exists with regard to the Gulfstream Model G-IV series airplanes. 
Accordingly, the proposed rule is hereby withdrawn.
    Withdrawal of this notice of proposed rulemaking constitutes only 
such action, and does not preclude the agency from issuing another 
notice in the future, nor does it commit the agency to any course of 
action in the future.

Regulatory Impact

    Since this action only withdraws a notice of proposed rulemaking, 
it is neither a proposed nor a final rule 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, the notice of proposed rulemaking, Docket 92-NM-206-
AD, published in the Federal Register on April 9, 1993 (58 FR 18347), 
is withdrawn.

    Issued in Renton, Washington, on June 7, 2000.

Acting Manager, Transport Airplane Directorate, Aircraft Certification 
Service.
