WebFor structural fasteners and joints, you must add a 'fitting factor' of 1.15 on top of the 1.5 factor of safety. For certain specific loads there are specific load factors. A common one for extra modifications is for items of mass in the flight cabin, for which you need to apply an 18G inertial load factor. WebFigure 12.2.2‑2: Mechanically Fastened Tension (out-of-plane) Loaded Joints Note: The strength of each joint is subjected to the 1.5 ultimate load factor used for all structural analysis per FAR 23.303/25.303. Joints at fittings are also subjected to an additional 1.15 fitting factor per FAR 23.625/25.625.
