## Discrepancy

BRIEFLY BEFORE ENTERING CRUISE FLIGHT, BOTH ENGINE CAD DISPLAYS SHOWED ENG PA DIS.  ALSO ROTOR RPM DROPPED TO THE POINT OF WP LIGHT AND HORN.  PILOT LOWERD POWER AND ATTEMPTED TO BEEP UP RPM.  LOWERING POWER BROUGHT UP ROTOR RPM.  AFTER CONSULTING CHECKLIST FOR WARNINGS, PILOT DECIDED TO ATTEMPT RUNWAY LANDING IN CASE THERE WAS NOT ENOUGH POWER TP HOVER.  AT 5 FEET THERE THERE WAS SUFFICIENT POWER AND ROTOR RPM TO HOVER SO PILOT OPTED TO HOVER OVER TO HANGAR TO LAND.   ACFT WAS TAKEN OUT OF SERVICE AND MAINTENANCE CONTACTED.
