There are no regulations on the subject, just recommendations. If anything
bad were to happen, "careless and reckless" would be the relevant
regulation.

I've heard people say things like - it's illegal to start
your plane by propping it by hand unless there's a licensed
pilot at the controls. Others have said it's illegal to use
the armstrong starter unless it's tied down. Does anyone
know what the applicable regulations, FAR's and Advisory
Circulars are on the subject of starting by hand?
