Proposed rule; withdrawal.
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 Accordingly, the proposed rule is withdrawn.Start Further Info

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.)
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 Accordingly, the proposed rule is hereby withdrawn.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. Start Printed Page 37314
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).Start List of Subjects
