SIL 0187 and TT Strap Installation
Just a heads up for those of you who may be installing the TT straps for the first time in your Enstrom. Be sure to check out Service Information Letter 0187 when you install the system. There is potential for interference between the retention pin and the U-Block. I wish this had been mentioned in the STC installation paperwork. We ran into all sorts of problems balancing the blades after the STC until we found this out.
