What’s a check cycle ?
Schedule of maintenance checks designed to ensure the continuing airworthiness of the aircraft.
( short haul fights have many check cycles a day as they complete several flights a day, however a long haul aircraft only has a few cycles due to only flying once or twice a day. )

- everything in aircraft is dismantled.
Where does the modification come from ?
- TC ( Type certificate ) holder.
- organisation.
( must take place under part 21 )
What will happen if the aircraft’s modification request is denied ?
Certificate of Airworthiness becomes invalid
What’s the two types of modification ?
Minor - doesn’t effect the aircraft’s mass or structural strength etc
Major - opposite to minor
What does the civil modification record hold ?
Record of modifications carried out by the organisation.
What’s a airworthiness directive ( AD ) ?
Released by EASA when it’s decided that a particular maintenance action is required to ensure the continued airworthiness of a specific aircraft.
What’s an emergency airworthiness directive ( EAD ) ?
Same as AD but the message to the operators with the infected aircraft has to get the message urgent.
What’s a service bulletin (SB) ?
Sent to operators informing them of concerns relating to a system affecting the aircraft safety which requires an immediate modification.
