Twenty-Third Meeting: RTCA Special Committee 225 (SC-225) Rechargeable Lithium Battery and Battery Systems
The FAA is issuing this notice to advise the public of the Twenty-Third RTCA Special Committee 225 meeting.
Airworthiness Directives; Dassault Aviation Airplanes
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 900 airplanes, FALCON 900EX airplanes, and FALCON 2000EX airplanes. This AD was prompted by a report that during a test flight, it was found that the yaw damper on the takeoff roll can increase the Minimum Control Speed on Ground (Vmcg). This AD requires revising the airplane flight manual (AFM) to incorporate procedures for the flightcrew to check that the yaw damper is set to ``off'' before takeoff. We are issuing this AD to ensure that the flightcrew has procedures to set the yaw damper to ``off'' before takeoff, which, if activated, could result in reduced control of the airplane if one engine were to fail during takeoff.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300B4-203 and A300B4-2C airplanes. This proposed AD was prompted by cracks found on pylon side panels (upper section) at rib 8. This proposed AD would require a detailed inspection for crack indications of the pylon side panels, a high frequency eddy current (HFEC) inspection to confirm any crack indications, modification of the pylon side panels, and repetitive inspections and repair if necessary. We are proposing this AD to detect and correct cracking of the pylon side panels. Such cracking could result in pylon structural failure and in-flight loss of an engine.
