Start Preamble

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 Dassault Model Falcon 2000 series airplanes. That action would have required performing an inspection to determine the serial number on the identification plate on each of the three hydraulic shut-off valve (HSOV) actuators on the left-hand and right-hand hydraulic reservoirs, and replacing an HSOV actuator with a new HSOV actuator, if necessary. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data indicating that the identified unsafe condition specified in the NPRM does not exist on the affected Start Printed Page 40824airplanes. Accordingly, the proposed rule is withdrawn.

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 Dassault Model Falcon 2000 series airplanes, was published in the Federal Register as a Notice of Proposed Rulemaking (NPRM) on August 23, 2002 (67 FR 54596). The proposed rule would have required performing an inspection to determine the serial number on the identification plate on each of the three hydraulic shut-off valve (HSOV) actuators on the left-hand and right-hand hydraulic reservoirs, and replacing an HSOV actuator with a new HSOV actuator, if necessary. The proposed actions were intended to ensure that proper HSOV actuators are installed on the hydraulic fluid reservoirs. In the event of an engine fire, a faulty HSOV, if not corrected, could allow the flow of flammable fluid to the engine nacelle, which could result in an engine nacelle fire that could not be readily extinguished.

Actions That Occurred Since the NPRM Was Issued

Since the issuance of that NPRM, the manufacturer has provided the FAA with confirmation that the faulty HSOV actuators on all affected Model Falcon 2000 series airplanes have been replaced with new actuators, and that all the faulty actuators have been returned to the airplane manufacturer.

FAA's Conclusions

Upon further consideration, the FAA has determined that the identified unsafe condition no longer exists on the affected airplanes. Accordingly, the proposed rule is hereby withdrawn.

Withdrawal of this NPRM constitutes only such action, and does not preclude the agency from issuing another action 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).
