Schedule of Overhauls and Service Work
Chapter 5
A yearly overhaul must be performed after 12 months (±1 month) after the last yearly
overhaul or from the start of utilization.
Admissible time tolerances for performing an overhaul do not add up. For example, (in case
of a constant specification of deadlines for overhauls as per the calendar) the fourth yearly
overhaul should be performed after 48±1 months rather than after 48±4 months. Performing an
overhaul earlier than the admissible tolerance requires the commencement of calculating
successive overhauls anew, from the date of a performed overhaul.
