Rigging corrective actions
It is particularly important that any rigging problems are dealt with in the correct sequence.
Use the flowchart below to work your way through any rigging problems: it may be necessary
to step through the flowchart more than once, but the sequence is very important so work
through each line one at a time, making corrections as indicated and retesting each time until
the rigging is correct.
Retest the aircraft after each adjustment has been made and keep working through the
flowchart from line #1 all the way to line #4 until you reach the “Rigging is correct” box at
the bottom left of the chart.
The Flight Testing form
Sequence #2
should be printed out and used to record information
while in flight. Print one form per test flight and retain each as a permanent record.
