Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, Model 757 airplanes, Model 767 airplanes, and Model 777 airplanes. This proposed AD results from fuel system reviews conducted by the manufacturer. This proposed AD would require an inspection to determine if certain spar-mounted motor-operated valve actuators for the spar-mounted fuel valves are installed, and replacement of any affected actuators. We are proposing this AD to prevent electrical energy from lightning, hot shorts, or fault current from entering the fuel tank through the actuator shaft, which could result in fuel tank explosions and consequent loss of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are superseding Airworthiness Directive (AD) 2013-16-08 for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, and Model CL-600-2D24 (Regional Jet Series 900) airplanes. AD 2013-16-08 required inspection of the main landing gear (MLG) retraction actuator components; corrective actions if necessary; and, for certain retraction actuators, installation of a new jam nut. This new AD continues to require those actions. This AD was prompted by a determination that a certain part was incorrectly identified in a certain section of AD 2013-16-08. We are issuing this AD to prevent disconnection of the MLG retraction actuator, which could result in extension of the MLG without damping, and consequent structural damage and collapse of the MLG during landing.
Policy and Procedures Concerning the Use of Airport Revenue; Proceeds From Taxes on Aviation Fuel
This action adopts an amendment to the FAA Policy and Procedures Concerning the Use of Airport Revenue published in the Federal Register at 64 FR 7696 on February 16, 1999 (``Revenue Use Policy''). This action confirms FAA's long-standing policy on Federal requirements for the use of proceeds from taxes on aviation fuel. Under Federal law, airport operators that have accepted Federal assistance generally may use airport revenues only for airport-related purposes. Local taxes on aviation fuel are subject to airport revenue use requirements. State taxes on aviation fuel (imposed by either an airport sponsor or a non-sponsor) are subject to use either for a State aviation program or for airport- related purposes. The statutory revenue use requirements apply to certain State and local government taxes on aviation fuel, as well as to revenues received directly by an airport operator. This document formally adopts, through an amendment to the Revenue Use Policy, FAA's interpretation of the Federal requirements for use of revenue derived from taxes on aviation fuel.
