Staggering into Annual Inspection

One of the unique things about the Yanks Air Museum is that several of their historic aircraft are still flying on a regular basis. This of course means that they must be regularly inspected and certified as safe to fly. During my recent tour I came across a few aircraft that were currently undergoing their annual inspections. This takes the form of a mandatory, comprehensive maintenance check performed every 12 months. It's designed to ensure the aircraft remains safe and deemed airworthy for continued operation.

This Beechcraft Model 17 Staggerwing was one such aircraft. Seeing it with its engine cowl removed and all of its cylinders on display was a rare opportunity to sort of pull the curtain back and get a peek behind the scenes so to speak. To my uneducated eye, all tools needed for the inspection were all spread out in front of it and since the inspector had wandered off, I took the opportunity to take a few images.
