What the agency says
The FAA is superseding Airworthiness Directive (AD) 2023-11- 01, which applied to certain Bombardier, Inc., Model BD-100-1A10 airplanes. AD 2023-11-01 required a records check and replacement of affected left-hand (LH) direct current power center (DCPC) units. AD 2023-11-01 also provided optional terminating action for the records check and replacement. This AD was prompted by multiple reports of erratic electrical system status on the push button annunciators (PBAs) and the engine instrument and crew alerting system (EICAS) while on- ground and during flight, and by the determination that certain DCPC units require additional modification or replacement. This AD requires checking maintenance records of certain airplanes, replacing certain DCPC units, and modifying certain DCPC units. This AD also expands the applicability of AD 2023-11-01 and prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
