Operational Inspection
An operational inspection is a check intended to determine that a component or system is fulfilling its
intended purpose. The operational inspection does not require quantitative tolerance.
Functional Inspection
When called for by an inspection task, a functional inspection is a quantitative check to determine if
one or more functions of a component perform within specified limits. The functional inspection is a
comparative examination of a component or system against a specific standard.
2.2.
CONDITION INSPECTION TASKS
If the aircraft is registered in the United States or other country following the same or similar
regulation, ASTM F2483 requires that all LSA category airplanes must undergo a complete inspection at
least once every 12 calendar months. An authorized maintenance person, as described in ASTM F2483,
must perform this inspection.
A signed and dated record must be maintained as each inspection task is completed. When the last
task of the inspection has been completed, the Inspection Report is to be signed off in the log
book/maintenance record. The inspection items to be covered in the condition inspection are identical to the
100-hour Inspection items. The inspection interval to the next condition inspection may not exceed twelve
calendar months.
2.3.
PERIODIC INSPECTION TASKS
If the aircraft is operated commercially (for hire) in the United States or other country following the
same or similar regulation, it must also have an inspection every 100 flight hours. The 100-hour interval
between inspections should never be exceeded by more than 10 hours, and then only if additional time is
required to reach a place where the inspection can be satisfactorily accomplished. Additionally, the time the
interval was exceeded must be included as flight hours in the next 100-hour interval. Inspection tolerances
cannot be accumulated.
2.4.
