Bombardier would like to inform Learjet operators that Stafoam Semkit, P/N 12135-067-001, has been discontinued by the vendor.   

This Semkit is used in multiple areas, most notably in Service Bulletin 35/36-51-4, Repair of Forward Engine Beam Shear Web.  P/N 12135-103-032 foam kits now replace the Semkit, which includes Stafoam P/N AA 1802M, Component R and Component T, as well as mixing instructions.   

New 12135-103-032 foam kits can be ordered through Bombardier Part Services and the material is drop-shipped directly from the supplier, Expanded Rubber and Plastics.
