SCHEDULED MAINTANANCE CHECKS
1. General
The following Table shows the maintenance tasks performed at defined intervals to retain an item in a
serviceable condition by systematic inspection, detection, replacement of wear out items, adjustment,
calibration, cleaning, etc. as applicable.
Where an interval is given in both flight hours and calendar years, the limit which is reached first must be
applied.
2. Inspection Program
A. The inspections are grouped as follows:
Table 1 - Flight Hours Inspection Group
A B (*) C (*) D (**) E
Flight Hours 50 FH 150 FH 550 FH 1000 FH 2000 FH
Calendar
Schedule
- 1 Year 3 Years 5 Years -
(*)The inspection tasks reported in this interval must be applied each 100FH/1 year for compliance to 14 CFR 43 -
Appendix D unless an alternative program has been FAA approved
(**) Where marked with **, the inspection tasks reported in this interval must be applied each 100FH/1 year for
compliance to 14 CFR 43 - Appendix D unless an alternative program has been FAA approved
NOTE: REFER TO TABLE FOR OTHER FLIGHT HOUR INTERVAL OF MAINTANANCE TASKS.
(1) For the interval of flight hours or calendar schedule inspection (WOF) refer to airplane, engines
and propellers log books.
(2) The airframe inspection time limits must not exceed by one (1) month or +10% FH, with a
maximum of 60 FH.
(3) Limit excess cannot be accumulated. If, for example, the initial 100 FH hour inspection is
performed at 110 FH, the 550 hours inspection is still due at 550 FH and the next 100 FH
inspection shall be accomplished after 90 FH.
(4) All the tasks are grouped in function of ATA-100 code.
(5) The first column shows the ATA code which the item belongs to, the second column shows the
system name, the third column shows the maintenance task and the last columns shows the task
frequency required, namely:
- Column A : if a “X” is indicated in this column, the task must be performed at each “A”
inspection
- Column B : if a “X” is indicated in this column, the task must be performed at each “B”
inspection
- Column C : if a “X” is indicated in this column, the task must be performed at each “C”
inspection
