Cessna 208B - Bulb Replacement During Flight

CESSNA SECTION 8
MODEL 208B (675 SHP)HANDLING SERVICE, AND MAINTENANCE
PROLONGED OUT-OF-SERVICE CARE (Continued)
C. 29 to 90 Days
- An engine inactive for a period exceeding 28
days, but less than 91 days, need only have the fuel system
preserved, engine openings covered, and desiccant bags and
humidity indicators installed.
D. 91 Days and Over - An engine inactive over 90 days in the
airframe or removed for long term storage in a container, must,
in addition to the 29 to 90 day procedure, have the engine oil
drained and unused accessory drive pads sprayed.
2. Place a cover over the
pitot tube, and install the two engine inlet
covers. To prevent the propeller from windmilling, install the
propeller anchor over a blade of the propeller and secure the
strap around the nose gear or to the bracket located on the lower
right hand cowl. Cover all other openings to prevent entry of
foreign objects.
3. Keep the fuel tanks full to minimize condensation in the tanks.
4. If the airplane will be out of service for 5 days or more, disconnect
the battery. If the battery is
left in the airplane, it should be
removed and serviced regularly to prevent discharge. If the
battery is removed from the airplane, check it regularly for state of
charge.
5. If the airplane is stored outside, tie-down the airplane in
accordance with the procedure in this section. Chock the nose
and main wheels; do not set the parking brake if a long period of
inactivity is anticipated as brake seizing can result.
6. Every two weeks, move the airplane to prevent flat areas on the
tires. Mark the tires with tape to ensure the tires are placed
approximately 90" from their previous position.
7. Drain all fuel drain points every 30 days and check for water
accumulation. Prolonged storage of the airplane will result in a
water buildup in the fuel which "leaches out" the fuel additive. An
indication of this is when an excessive amount of water
accumulates at the fuel drain points. Refer to Fuel Additive in this
section for minimum allowable additive concentrations.
BULB REPLACEMENT DURING FLIGHT

I
Figure 8-6 provides instructions to aid the pilot to replace annunciator
-,
panel light bulbs without tools during flight. It is suggested that spare
bulbs be stored in the map compartment. However, if a spare bulb is
=)
not available, an identical bulb which is found to be available from other
lights listed herein can be substituted for the defective bulb. For a listing
=,
of other bulb requirements and specific tools needed, refer to the
Maintenance Manual for this airplane.
