Aircraft general knowledge

For smaller aircraft, a new system has been established called CAO (Combined

Airworthiness Organization).

Aircraft that are not used commercially may be maintained under a CAO. The

rules here are less stringent than in a CAMO.

8.2.1.4 Faults and defects in components

There are component cards on most parts of the aircraft. These cards list
inspections that have been carried out.

If the manufacturer discovers faults that regularly occur in a component, a

Service Bulletin is issued, which states when and what must be done to ensure,

through inspection and repair, that a faulty part is replaced or serviced, so that

flight safety can continue to be met.

8.2.1.5 Daily inspection and maintenance

The pilot has daily responsibility for inspecting the aircraft. This also includes

functional tests of the engine, landing gear, rudder, flaps, etc.

It is also the pilot who must take the consequences of the condition of the

aircraft. Trust in the aircraft mechanic is good, but control is better!

If you discover a fault in the aircraft, you have to request a mechanic BEFORE

flying. Remember to write faults and comments in the aircraft logbook, both for
your own sake and that of any co-pilots.

For privately operated aircraft, it is possible for the owner to participate in the

maintenance himself. There are rules for how much repairs you are allowed to

make on your aircraft. Check with the current BLs (available at navair.dk and

trafikstyrelsen.dk).
