In 2014 Van’s Aircraft put out a service bulletin for potential cracking in the horizontal stabilizers of the RV-6, RV-7 and RV-8 series of aircraft. While the service bulletin calls for annual inspections in this area, I recommend more frequent checks for those aircraft that are regularly performing aerobatics. The crack shown in the photo was discovered two months after a condition inspection.
