Carefully
Not sure how you are equipped. If you have a searchlight mounted on the left side, make sure it is stowed horizontal on landing. (some of the searchlights that have the IR filters attached do not retract to the full horizontal so watch out for rocks) If able refrain from mounting FLIR's on the belly, put it up on the nose if able. Keep the struts fully serviced. The tires and low clearance are the weakness. Expect to go through main tires on a regular basis. They are gouged easily on sharp rocks. Dust landings are like any other ship. The 139 has a suprisingly high rotorwash though. so expect to get dirty. For the short nose 139 if you keep the wings level on the artificial horizen and pull t/o power it comes up in a good attitude for recovery. (experiment for yourself but that works good for me)
