The Australian Transport Safety Bureau recommends that General
Electric Aero Engines:
a) Review the suitability of using Inconel 625 alloy consumables
during the weld repair of high-pressure turbine blades.
b) Review the life estimate and inspection intervals for
high-pressure turbine blades repaired under the procedures using
Inconel 625 alloy consumables.
c) Notify all operators using CFM56-2C, CFM56-2A/2B, CFM56-3 or
similar engines of the possibility of catastrophic engine failure
due to failure of high-pressure turbine blades repaired using
Inconel 625 alloy consumables.
