A PART 135 CARGO PLT LANDS WITH GEAR NOT EXTENDED AND MANAGES TO PERFORM A GAR WHEN A SCRAPING SOUND WAS HEARD AT ZZZ.

Narrative

I APCHED ZZZ. I WAS HELD HIGH AND TOLD TO KEEP SPD HIGHER THAN I USUALLY DO. DURING THE DSCNT; I LOWERED THE GEAR HANDLE. THE GEAR DOORS WERE OPENING AND I CONTINUED MY DSCNT. RELEASED TO TWR AND DSNDING; I LOWERED THE FLAPS. FLAPS TAKE 27 SECONDS TO REACH THE 20 DEG SETTING. AT THIS POINT; THE GEAR HORN SHOULD SOUND. THE GEAR HORN CAN ALSO BE ACTIVATED BY A REDUCTION IN PWR TO FLT IDLE. I WAS UNABLE TO REDUCE PWR TO FLT IDLE DUE TO THE NEGATIVE TORQUE SENSING SYS ACTIVATING. EVEN THOUGH THE GEAR HANDLE WAS DOWN; THE GEAR DID NOT EXTEND. I CONTINUED THE APCH TO LNDG; NOT NOTICING THE GEAR INDICATORS WERE NOT SHOWING THE GEAR TO BE DOWN. I HEARD THE BOTTOM OF THE AIRPLANE SCRAPE THE RWY; PULLED THE YOKE BACK AND ADDED PWR. DURING THE CLB AND RETURN FOR LNDG; I WAS ABLE TO GET THE GEAR DOWN. I RETURNED FOR A LNDG WITH NO FURTHER PROBS AND LANDED. SEVERAL FACTORS CONTRIBUTED TO THIS INCIDENT: ABOVE NORMAL APCH ALTS AND SPDS; FAILURE OF THE GEAR TO EXTEND; AND PLT NOT VERIFYING GEAR WAS DOWN. TO PREVENT THIS FROM HAPPENING AGAIN; ATC COULD HAVE PROVIDED A MORE STABLE APCH WHICH WOULD HAVE GIVEN ME MORE TIME FOR PROPER PROCS. I SHOULD HAVE CHKED THE GEAR INDICATORS AND FOLLOWED PROCS.
