Interval

Hi,
intervals vary from airline to airline. As LeandroSecundo already stated for what is called simplified C-Check the interval is +/ - 18 month.

see below extract from a A330 maintenance requirement
Code:
CHECK       MAX. INTERVAL
MPC
PFC         Before each departure 
W           14 calendar days
A           800 FH since
C           1C = 18 months 
           2C = 36 months 
           4C = 72 months 
           8C = 144 months 
IV          1IV = 6Y = 72 month 
D           1D =12Y =120month
