Static load equal and JAR 29.865
As known the JAR 29.865 describes external loads specification and design. I'm now in discussions how to interprete the static load in case of human external loads. A 3,5 load factor to the maximimum external load for which authorisation is requested. OK, but our CAA means that on a 1000kg approved and certified load hook, load attachment point or connection part produced by an external manufacturer our load is to cut to 285kg. Thats not my opinion because i think the external manufacturer was controlled to design and test the 1000kg hook or part to a load factor of at least 2,5 means 2500kg. Therefore our (human)load is right up to 714kg.
Additionally the new CAA inspector would love to add a 1,5 "general safety" factor. Means 3,5 + 1,5 = 5,0 and a limited human load from max. 200kg on a 1000kg certified part. The whole system is redundant of course and consists of two hooks and 2 lines. But the discussions turning around the max permitted human load to one system (in case of other system failure).
Any advices?
