4.2. AIRCRAFT WALK-AROUND
To perform the aircraft walk-around, carry out the checklists according to the pattern
shown in Figure 4-1.
Visual inspection is defined as follows: check for defects, cracks,
detachments, excessive play, unsafe or improper installation as
well as for general condition. For control surfaces, visual in-
spection also involves additional check for freedom of movement
and security. Red lubber lines on bolts and nuts shall be intact.
Fuel level indicated by the fuel quantity indicators must be veri-
fied by visual check of actual fuel quantity embarked in the tanks:
graduated dipstick must be used.
If ignitions key is in L/R/BOTH position, a propeller movement
can cause the engine starting with consequent hazard for people
nearby.
Fuel drainage operation must be carried out with the aircraft
parked on a level surface. Set Cockpit Fuel Selector Valve to
OFF prior to drain fuel.
