F Flying Scotsman Well Known Member Jun 12, 2010 #1 Simple question: can lock washers (star type, internal) be reused and if so, how often (what criteria to use to judge when to replace them)?

Mel Legacy Member Mentor Jun 12, 2010 #3 "Star" type lock washers tend to get flattened. I recommend using them only once.
az_gila Well Known Member Jun 12, 2010 #4 In general... ...lock washers should not be used on primary structures (per AC 43.13) and I can't think of any on the RV. They are specified by Lycoming all over the engine, and Lycoming is very specific NOT to reuse any lock washers.
