## Discrepancy

TAIL ROTOR PEDALS JAMMED DURING FLARE TO A HOVER. AIRCRAFT LANDED WITHOUT INCIDENT. UPON INSPECTION IT WAS FOUND THAT THE TAIL ROTOR PEDAL BLOCK SUPPORT BRACKET ON THE RT SIDE HAD CRACKED AT THE AFT PEDAL BLOCK ATTACH POINT ALLOWING THE PEDAL BLOCK TO PIVOT DOWN AND JAM THE PEDALS. REPLACED BRACKET WITH NEW.
