## Discrepancy

WHILE TAXING THE AIRCRAFT AFTER LANDING THE FLIGHT CREW NOTICED THERE WAS A LOSS OF BRAKING ON THE LH SIDE.  FOUND LEAKING BRAKE FLUID OUT OF THE LH BRAKE LINE WHERE IT GOES TO THE CALIPER.  TIGHTENED THE BRAKE LINE GOING INTO THE LH OUTBOARD CALIPER.  BLED THE BRAKES AND LEAK CHECKED GOOD IN ACCORDANCE WITH THE BEECHCRAFT 99 MAINTENANCE MANUAL.  NO DEFECTS FOUND AT THIS TIME.  NO FURTHER ACTION IS REQUIRED.
