2016-25-02: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This AD was prompted by reports of the accumulation of very fine particle deposits in the power control unit (PCU) electro-hydraulic servo valves (EHSVs) used in the flight control system; this accumulation caused degraded performance due to reduced EHSV internal hydraulic supply pressures, resulting in the display of PCU fault status messages from the engine indication and crew alerting system (EICAS). This AD requires installing markers to limit the hydraulic system fluid used to a specific brand, doing hydraulic fluid tests of the hydraulic systems, replacing hydraulic system fluid if necessary, and doing all applicable related investigative and corrective actions. We are issuing this AD to address the unsafe condition on these products.

96-23-13: This amendment adopts a new airworthiness directive (AD), applicable to certain Canadair Model CL-215-1A10 series airplanes. This action requires a one-time inspection of the three DC generators to ensure that the extra unconnected bare copper wire is properly stowed. This amendment is prompted by reports indicating that unconnected bare copper wire, which was fitted inside of some DC generators installed on these airplanes, could cause a short circuit. The actions specified in this AD are intended to prevent a fire hazard that would be posed if a short circuit were to occur at this area in the presence of a combustible fuel-air mixture.

97-01-09: This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A321 series airplanes. This action requires repetitive inspections to detect cracking and delamination of the doors that contain the left and right emergency evacuation slides located at certain emergency exits; and repair or replacement, if necessary. This action also requires the accomplishment of a modification that serves as terminating action for the repetitive inspections. This amendment is prompted by a report indicating that a slide aboard an airplane deployed during flight and consequently separated from the airplane. The actions specified in this AD are intended to prevent the loss of these slides during flight, which could make certain exits unusable in the event of an emergency, and also damage the empennage.

2016-25-26: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model MD-90-30 airplanes. This AD was prompted by reports of stick shaker activation at airspeeds that were above the stall protection system's stick shaker schedule. This AD requires installing angle-of-attack (AOA) sensor external case heaters on the existing AOA sensors, installing additional wires, and doing a functional test and applicable corrective actions. We are issuing this AD to address the unsafe condition on these products.
