I am doing my 12th condition inspection and looked at the flap hinge and they look a bit dirty after collecting dust for the the 12 years. I typically squirt some LPS2 on them every year and that seems to be attracting dirt. I decided to pull the pins and clean and lubricate.
Questions for the group: How often should you pull the flap hinge pins and inspect, clean, lubricate? Should I be using something other than LPS2 that collects less grim?
This leads to more general question on pulling hinge bolts. I annually pull bolts that something rotates on, like the rudder attach cable bolts and airbox bypass door pull cable, every year to look for wear on the bolt. I do not for rod ends that are clamped up. I will squirt in some LPS2 but it is hard to really get the lubricant onto the rod end due to the clamp up with washers. How often should I pull those bolts to lubricate and look for bearing wear?
