MEL Intermittent faults

[T120Bobber]

With a repetitive intermittent MEL defect, lets say a "ENG 1 FIRE LOOP A" message, you'd get ten days, (CAT C), from original date of deferal to fix it.

After carrying out rectification maintenance and replacing a part you could test it and if the test is good release the aircraft and clear the DD. I'm talking about the type of defect that only appears intermittently in flight here.

If however the defect returned again within say, three days or cycles, the defect would be considered still present and the DD would again be raised but with the ORIGINAL defect deferal date.

Does anyone know or think any different? Does anyone know if the FAA/EASA rules have changed?

Thanks for any input.
