I recently purchased a modified Bensen autogyro with Dragon Wing blades. The previous owner used AN 4-15A bolts ( with nylock nuts) in the rotor straps - six on each side. I question the practice. I have always used drilled bolts with castle bolts and safety pins and have always considered this “best practice”. Cost is not an object here. Any thoughts out there on the relative safety of each method in this circumstance?
