Brief Description: Drill the inspection hole doublers
There are eight inspection holes on the lower wing skins which provide access for inspection of the flight controls. We drilled the rivet holes in the doublers before we have lots of wires and tubing in the way. We numbered and engraved each doubler and plate so when it comes time for installtion and services the same plate will be fitted. Utilizing cleco's we drilled through the doubler and plates. All doublers and plates were given corrosion proof.
