summary: The FAA is adopting a new airworthiness directive (AD) for certain Pilatus
  Aircraft Ltd. (Pilatus) Model PC-12/47E airplanes. This AD was prompted by a report
  that, during an engine start on the ground, the airplane battery voltage dropped
  to a value that resulted in an avionic system shutdown. This AD requires incorporating
  a temporary revision (TR) into the existing pilot's operating handbook (POH) for
  the affected airplanes to provide operators with instructions for an enhanced engine
  start procedure. The FAA is issuing this AD to address the unsafe condition on these
  products.
