This work session was completed on June 5, 2021
This service bulletin is due to cracking of the F-01478 Aft Fuselage Forward Bottom Skin. The service bulletin was released after I ordered my kit, so I ordered the appropriate parts to comply with the bulletin. Here is the LINK to service bulletin on the Van’s website. My Uncle was in town to help install the Wings, so he also helped me out on completing/complying with the service bulletin.
A total of five individual parts were used and installed as instruction in the bulletin. Shown below are three of the parts and their final installed location in the airplane:
Part #1: F-14147-R Stiffener Clip (left circle)
Part #2: F-14148B Stiffener Doubler (middle circle)
Part #3: F-14147-L Stiffener Clip (right circle)
This is aft side of the picture above. The circles on the left and right are just showing the manufactured side of the AN470 rivets installed on the two Stiffener Clips.
Part #4: F-14148C (center circle)
Part #5: F-14148A Skin Doubler
The round end of the Skin Doubler is oriented forward and the blunt end is oriented aft.
