Airworthiness Directives; MD Helicopters, Inc. Model MD900 (including the MD902 Configuration) Helicopters
This document proposes adopting a new airworthiness directive (AD) for the specified MD Helicopters, Inc. (MDHI) model helicopters that would require, within 30 days, reducing the current gross weight limit to a maximum gross weight limit of 5,400 pounds and inserting a copy of this AD into the Limitations section of the Rotorcraft Flight Manual (RFM) or making certain optional modifications that constitute terminating actions. This proposal is prompted by flight tests that show that the information currently listed in the Limitations section of the RFM is inconsistent with the actual performance of the helicopter. The actions specified by the proposed AD are intended to prevent loss of directional control of the helicopter.
Airworthiness Directives; Bell Helicopter Textron Canada Model 222, 222B, 222U, 230, and 430 Helicopters
This document proposes superseding an existing airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) helicopters. That AD currently requires certain checks and inspections of the tail rotor blades. If a crack is found, the existing AD requires replacing the tail rotor blade (blade) with an airworthy blade before further flight. This action would require the same checks and inspections until they are required to be replaced and would remove certain serial numbered and specifically coded tail rotor blades from the applicability of the AD. This proposal is prompted by the approved rework of certain tail rotor blades and two newly redesigned tail rotor blades, which, if installed, constitutes terminating action for the inspection requirements. The actions specified by the proposed AD are intended to detect a crack in a blade, and to prevent loss of a blade and subsequent loss of control of the helicopter.
Consensus Standards, Light-Sport Aircraft
This notice announces the availability of three new consensus standards and a revision to a previously accepted consensus standard relating to the provisions of the Sport Pilot and Light-Sport Aircraft rule issued July 16, 2004, and effective September 1, 2004. ASTM International Committee F37 on Light Sport Aircraft developed the new and revised standards with Federal Aviation Administration (FAA) participation. By this notice, the FAA finds the new and revised standards acceptable for certification of the specified aircraft under the provisions of the Sport Pilot and Light-Sport Aircraft rule.
Airworthiness Directives; McDonnell Douglas Model DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, DC-10-40F, MD-10-10F, MD-10-30F, MD-11, and MD-11F Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain McDonnell Douglas transport category airplanes. The existing AD currently requires modification of the installation wiring for the electric motor-operated auxiliary hydraulic pumps in the right wheel well area of the main landing gear; repetitive inspections of the numbers 1 and 2 electric motors of the auxiliary hydraulic pumps for electrical resistance, continuity, mechanical rotation, and associated airplane wiring resistance/voltage; and corrective actions if necessary. This proposed AD would, for certain airplanes, also require modifying and rerouting, as applicable, certain components of the wiring of the electric motor for the auxiliary hydraulic pump located in the right wheel well. This proposed AD results from reports of failure of the electric motor for the auxiliary hydraulic pump. We are proposing this AD to prevent failure of the electric motors of the hydraulic pump and associated wiring, which could result in fire at the auxiliary hydraulic pump and consequent damage to the adjacent electrical equipment and/or structure.
