Received the SB kit for HS spar reinforcement and read through the instructions.
Also reviewed the Anti-Splat Aero video with an alternative stainless steel reinforcment part.
Will get the HS down from the storage shelf and review the steps. Final decision to install will be made then.
UPDATE: Just reviewed latest SB (14-02-05.pdf) and advice to not install as a preventative measure. In addition, will reivew installation details carefully to check elevator alignment, when the time comes.
