of operation.

in accordance with Chapter 05-20-00 section Maintenance Schedule.
This means for example that. every 100 hr of operation a 100 hr. check must be carried
out. Every 200 hr. of operation a 100 hr. and the additional checks for 200 hr. must be car-
ried out.

annual check
• In order to demonstrate continued airworthiness, an engine must be inspected after
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.
Special hr. check
NOTE
This maintenance schedule contains a column for a 50 hr. check. This check is
recommended by the manufacturer but not essential, with the exception of oil
change when operating with leaded AVGAS.
25-hr. check • In order to demonstrate continued airworthiness, an engine must be inspected after the
first 25 hours of operation.
• The checks performed at the 25 hr. inspection are the same as for the 100 hr. inspec-
tion. This applies both to newly delivered engines and to overhauled engines.
