Thanks, Scott. This makes sense and is similar to the stab spar bulletins we received a while ago for the RV-6/7/8: Inspect... If cracks found, perform the beef-up modification.
I wish this RV-12 Safety Bulletin had been more specific as to what satisfies the initial "inspection." We removed the empennage fairing today and borescoped/photographed the spar, finding no evidence of cracks on our RV-12 that had only 10 hours total airframe time. Then we flew the -12.
It would not have made sense to be required to remove and disassemble the stab and brackets for this initial inspection. The fact that the SB requires the modification to be performed at the next 100-hour/condition/annual inspection is more than cautious enough. There are probably a lot of RV-12 folks out there that might confuse the wording of the SB, thinking their airplanes are grounded until the stab is disassembled and inspected. That would strand a whole lot of airplanes!
Cudos to Van's for getting the engineering analysis completed and modification kit produced so quickly for this SB.
