4.2. Preflight inspection
Even if the CTLS was operated within the last 24 hours, it is essential that the aircraft
be thoroughly inspected before the first flight of each day. This also means removing
the engine cowling.
Warning:
The inadvertent start-up of the engine is dangerous! Always ensure that
the ignition and master switch are off.
Inspection details are given in the Rotax engine operating handbook. This pilot’s
operating handbook can only deal with the more important points.
Oil quantity can only be checked after the propeller has been slowly cranked (always
crank in the rotation direction of the propeller, never against the direction of rotation)
until a gurgling noise is clearly heard. Only then has the measurable amount of oil
been transported into the oil reservoir. The amount of oil must lie between the two
limits on the oil dipstick - max. /min. - and should never be allowed to sink below the
minimum level. Before undertaking an extended trip, make sure that the oil level lies
at least midway between the two limits. Do not overfill the tank.
Warning:
If leakage of operating liquids is discovered, the engine may not be
started until the cause of the leakage has been rectified. This is
particularly important in the case of oil and fuel leaks as both constitute
a fire risk.
The various propellers which can be installed in the CTLS are made of light-weight
composite materials. In comparison to propellers from the General Aviation sector,
these propellers do not consist of a wooden core which has been covered with
composite material. Should such a full-composite propeller be damaged, then the
entire load-carrying structure is affected. The propeller can no longer be used and
must be inspected by a qualified technician. The same applies to the spinner. It is
subject to high loads which can cause the smallest damage to grow very quickly. If it
is damaged it too may no longer be used. If necessary, the aircraft may however be
flown to an aviation workshop without the spinner cap.
Should cracks appear in the finish, the cause should be sought immediately. Cracks
in composite structures are often indication of damage to the underlying structure. A
qualified technician often has the means to check the structure without first having to
remove the finish.
During the inspection of the cockpit and the baggage compartment, particular
attention should be paid to loose objects. Objects easily fall out of bags and/or
pockets when leaving the aircraft. These objects can then shift during flight and
interfere with the control surfaces.
When flying alone, the passenger seat safety harness should be pulled tight and
locked. No loose objects should be on the passenger side as they are not accessible
to the pilot during flight.
Warning:
The passenger seat is not intended for the transport of objects or bags.
However, should objects (e.g. bags) be placed on the passenger seat,
