1. Inspect surface for damage and cracks, look out for signs of hidden structural
damage, check lower surface for damage caused by stone strike, check
registration marks and renew if necessary, check drain outlets.

2. Check static pressure ports and flexible hoses from the tail boom via the
central fuselage to the cockpit
X X X
3. Inspect bellcrank lever of the elevator control system in the base of the fin by
means of an endoscope introduced through the two inspection holes for tight fit
of all bolt connections, proper condition of the bearings, and for cracks,
deformation and other damages.

4. Examine push pull rods in the terminal swaging area for embrittlement or crack
initiation (axial and peripherical direction), check fork terminals for cracks,
particulary the fork terminals where the root turns into the webs.
