Section 4 - Pre-flight Inspection
A quick review of your logbook will make it obvious how long ago it was that you flew in a
Yak 18T. Whether you are the sole owner or a shareholder, you should always treat the
aircraft with critical and suspect eyes. Whether you were the last to fly just yesterday or not,
always perform an unrushed formal pre-flight inspection. The number of AAIB reports
indicating inadequate pre-flights is
unnecessary and avoidable. It takes 15-30minutes to do a
good pre-flight; the best advice is to know what to look for and
CHECK PROPERLY
.
The following suggested pre-flight inspection is targeted at the pilot who is travelling alone –
hence the structure of the checks and the engine starting procedures. The process of
conducting the pre-flight inspection for those with willing and able assistance will no doubt be
improved. In any case, it is recommended that you take full responsibility for all of the
checks, allocating only insignificant tasks to others until you are convinced of their
competence.
4.1. Preliminary Pre-Flight Actions

covers and protective caps i.e. pitot cover, propeller cover, oil cooler stop, cockpit cover,
aileron and rudder gust tabs are removed.
