annual check

every 100 hours of operation or 12 months.

• For the intervals between maintenance work, a tolerance of ±10 hr. is permissible, but

these tolerances must not be exceeded. This means that if a 100 hr. check is actually

carried out at 110 hr., the next check will be due at 200 hr. ±10 hr. and not at 210 hr. ±10

hr.

• If maintenance is performed before the prescribed interval, the next maintenance check

is to be done at the same interval (e.g. if first 100 hr. check is done after 87 hours of op-

eration, the next 100 hr. check must be carried out after 187 hours of operation).

• If engine has less than 100 hours of operation during one year a 100 hr. check must be

carried out. For the annual inspection a tolerance of ±2 months is given.
