I just pulled the FMEA for the Command Sensor Unit (CSU) and it consists of 234 A size pages not including the cover sheet. If I remember correctly the FMEA for the Power Control Unit (PCU) was twice that of the CSU FMEA.
By contrast the FMEA for the Flap Slat Computer was ten pages or somewhere near that amount.
The Flap Slat Computer is a thousand times more complex than the CSU and they crammed the FMEA into ten or so pages. That Flap Slat Computer is riding on every A-310.
