tank

6.3 PERIODIC INSPECTION
The safe operation and the airworthiness of the aircraft are directly dependent on thorough
and complete maintenance and repair of all aircraft parts. The aircraft is highly at risk of
losing its airworthiness if it is not maintained and serviced according to this manual and to the
Flight Manual. The inspections and maintenance intervals do not depend on the terms stated
below, but on the operational conditions and on the overall shape of the aircraft.
Nevertheless, minimum number of periodic inspections are:
•
Before each flight.
•
After the first 25 hours of flying.
•
After every 100 hours of flying, or once a year (whichever comes first).
6.3.1 Pre-flight Check
Perform pre-flight inspection prior to each flight, or after rigging the aircraft. The
recommended procedure for the pre-flight check is described above in paragraph 4.5.
6.3.2 Inspection after first 25 hours and 100 hours of flight
Dismount the covers and decking in the cockpit. Clean both the surface and internals of the
aircraft. Look for ruptures, damages, wear, excessive clearances and malfunctions. Lubricate
the movable parts with a suitable lubricant.
