Narrative:

I approached ZZZ. I was held high and told to keep speed higher than I usually do. During the descent, I lowered the gear handle. The gear doors were opening and I continued my descent. Released to tower and descending, I lowered the flaps. Flaps take 27 seconds to reach the 20 degree setting. At this point, the gear horn should sound. The gear horn can also be activated by a reduction in power to flight idle. I was unable to reduce power to flight idle due to the negative torque sensing system activating. Even though the gear handle was down, the gear did not extend. I continued the approach to landing, not noticing the gear indicators were not showing the gear to be down. I heard the bottom of the airplane scrape the runway, pulled the yoke back and added power. During the climb and return for landing, I was able to get the gear down. I returned for a landing with no further problems and landed. Several factors contributed to this incident: above normal approach altitudes and speeds, failure of the gear to extend, and pilot not verifying gear was down. To prevent this from happening again, ATC could have provided a more stable approach which would have given me more time for proper procedures. I should have checked the gear indicators and followed procedures.

Title: 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.
