Procedure; Human Factors; Aircraft
Was landing after flying the second jump-load of the day. Jump run was to 14;500 MSL. There was active sailplane/glider ops taking place at the same time. Tow plane was landing and on left base for runway. I was number 2 to land. Due to the moderate right crosswind of 10-15 knots; I elected to use approach flap setting. I failed to extend the landing gear as part of my pre-landing checklist. Landed gear up. The aircraft had the landing gear warning breaker pulled; as well as the stall warning. This is common in the skydiving industry when utilizing a Kingair as a jump plane. Due to the climbs that are at Vyse (best rate of climb). Jump runs at 90-95 knots indicated airspeed; with power pulled back to 200 LBS of torque on each engine and a 1000 FPM descent established. Both alarms will incessantly go off while on climb and jump run; distracting the pilot.Fix to the problem. Mandate that all skydiving operations utilizing a Kingair or any retractable gear airplane; conduct all operations with the landing gear down and locked at all times.
King Air pilot reported a gear up landing following a skydiving operation that typically deactivated the landing gear warning to prevent unwanted warnings during jump runs.
