## Discrepancy

LANDING GEAR HYD. ACCUMULATOR MOTOR CYCLED IN FLIGHT CAUSING CAUTION TO COME ON. AIRCRAFT WAS JACK AND TROUBLESHOT, FOUND SERVICE SELECTOR VALVE TO BE LEAKING INTERNALLY. THIS IS THE SECOND TIME THIS HAS OCCURED IN TWO YEARS. REMOVED AND REPLACED WITH NEW VALVE. PROBLEM WAS CORRECTED.
