Is P&W the only place that these inspections can be done?
The AD says this:
...
perators must conduct a thermal acoustic image (TAI) inspection of the large titanium fan blades located at the front of each engine. TAI technology can detect cracks on the interior surfaces of the hollow fan blades, or in areas that cannot be seen during a visual inspection.
I've been in UA hangers where they were performing similar tests on 737 fan blades (during a 2018 737-NG grounding IIRC) and I know that fan blade inspections can generally be done in MX hangars.
