Refurbishment

Repair of turbine components is now a procedure accepted by most operators. Few, however, have the resources to carry out the repairs themselves.

Refurbishment

The repair methods and limits for flying gas turbines are detailed by the engine manufacturer and are commercially available in manuals. This is not generally the case for heavy industrial gas turbines where each repair company has developed its own repairs.
