Pre-flighting a J-3 Piper Cub

Since there's no Pilot Operating Handbook for the early Cubs, it follows that there's no standard pre-flight check list. If you run into an FAA examiner, you may be challenged to do your pre-flight from a written checklist, and if the FOB's checklist is as daunting as mine was, you may prefer to create your own. Here's the one I use, printed on the front and back of a 3x5-inch file card:

Runup: CIGARS


The "CIGARS" is there in case the inspector wants to see a written pre-takeoff checklist. If you don't know the acronym, here it is:

C for Controls free and correct (the customary H)
I for Instruments correct (I read them aloud from port to starboard)
G for Gas correct (I go from starboard back to port)
A for Attitude correct (trim neutral for takeoff)
R for Runup
S for Safety check
