## Discrepancy

(CAN) AIRCRAFT WAS TAXIING AWAY FROM DOCK WHEN FLIGHT CREW DEMANDED REVERSE POWER FROM NR 2 ENGINE.  IT FAILED TO RESPOND AND AIRCRAFT HIT THE DOCK WITH FRONT OF RT FLOAT.  FAILURE OF PROP TO RESPOND TO POWER LEVER INPUT IS ATTRIBUTED TO THE PROP OVERSPEED TEST SWITCH FAILING IN THE ON POSITION.
