The Federal Aviation Administration (FAA) has proposed a new airworthiness directive (AD) for specific Bombardier Model BD-100-1A10 airplanes due to DC motor pump (DCMP) failures that occurred during production flight tests. This proposed AD would require installing a redesigned DCMP electric motor assembly to prevent disconnection of electrical system generators caused by excessive voltage. Comments on this proposal are welcome until April 12, 2021, and the FAA aims to address the unsafe conditions in these airplanes with this directive.
Simple Explanation
The FAA wants some airplanes to get new parts to stop an important component from breaking. They're asking people to share their thoughts about this idea by April 12, 2021, so they can make sure airplanes stay safe.
