The T/R Gearbox was disassembled, cleaned, paint stripped, and inspected which includes checking the dimensional measurements are within correct tolerance. The T/R Gearbox components and cases were then sent for NDT (crack detection). After returning from NDT, various components were re-protected in accordance with the appropriate manuals. 

The T/R Gearbox was then reassembled and sprayed with epoxy primer, followed by two coats of polyethylene paint in the appropriate colour.
