CAT certification — how much does shop experience actually help on the exam?
I've got 4 years on commercial aircraft avionics and I'm preparing for the Certified Aerospace Technician exam. My employer's covering the registration but I'm handling my own prep. The content breakdown includes airworthiness regulations, technical documentation, maintenance procedures, and safety systems. My daily work covers most of that but regulations have never been my strong suit — I follow them, I don't study them.
Currently 10 weeks out at 1.5 hours a day. Practice scores sitting at 74-77% against a 70% passing threshold. I've got buffer but I want more. FAA regulations and documentation standards are where I keep dropping points.
Does the CAT exam expect you to know specific FAR numbers and section references, or is it more conceptual — like “this situation falls under what category”? Also wondering if maintenance planning content is heavier than the breakdown suggests. Someone told me it's 30% of questions but that seems high.
Shop experience helps a lot on practical scenario questions but almost nothing on the regulatory section. I've seen guys with 15 years on the floor fail because they couldn't name specific regulation categories.
It's conceptual, not specific FAR numbers — you need to know which category applies. That should save you from the memorization nightmare.
Maintenance planning was about 20% on my exam, not 30%. Heavier on scheduling logic and resource allocation than procedure recall, which actually plays to practical experience.
Avionics background is solid preparation. Safety systems should be straightforward for you. Focus the last 3 weeks purely on regulations and you'll be in good shape.
74-77% practice with a 70% threshold sounds fine but exam anxiety can drop you 5 points. I'd want to be consistently at 80% before feeling comfortable.
Know the difference between airworthiness directives, service bulletins, and AMMs cold — that section hit harder than I expected.
