Plain English Summary

3/10 complexity

This instrument shortens the certified service life for the High-Pressure Turbine Stage 2 disk on GE CF6-50 and CF6-45 engines and makes compliance mandatory by requiring operators to follow FAA Airworthiness Directive 95-08-03 (with technical detail in GE SB 72-1069).

It affects operators, owners and maintenance organisations, forcing earlier inspections/overhauls or replacements and shifting direct maintenance costs, scheduling and record-keeping responsibilities onto them.
