Hi,
It's very hard to have that kind of data because most of companies dislike to reveal them. The technicals departments of the liners compute differents reliability ratio:
The main ratio is punctuality means quantity of scheduled flights minus the delayed flights due to an technical event (per day or week or month)
The second ratio is the reliability of the fleet means scheduled flights minus canceled flights due to a technical event.
These two main calculations are requested by the authorities.
However, depending of the policy of the company, you can have a calculation per type of aircraft, per ATA, per ATA & subATA, and the MTBF per flight hour, per cycle per check interval, depending what you are looking for.
I hope my explanations are clear enough for you and I apologize for my english skill.
