Does anyone know the email address at FAA I can ask what constitutes a major modification (I think it is FAR 21.23) on my 10? Ie painting.
Whatever your FSDO says it is. Seriously.
Well, no, not really. What is acceptable to one FSDO may not be acceptable to another, which runs the risk of causing problems down the line and while trying to please the FAA or CAsA is always a good idea, education "sometimes" works too.Amen! based on experience
