Tow hook
After a wheel-up landing, the C.G. tow hook is to be cleaned. Check tow
hook and tow hook bulkheads carefully for any damage.
C.G. weighing:
After all work which may influence the C.G.
Propeller
In addition to the instructions given in the propeller manual you have to
check the torque of the propeller bolts if you operate your aircraft in
varying temperature and humidity conditions. Especially high ambient
temperature and low humidity are likely to cause shrinkage of the
wooden propeller and thus loss of torque (pre-tension) which may lead to
failure of the propeller bolts. To check see section 3.5.1 item 33 of this
manual.
