Building an aircraft alone is where mistakes hide. The fix is free: an EAA Technical Counselor visits your project during the build, and an EAA Flight Advisor helps you plan that first flight. This article shows how to find the right person, when to call them, and how to get real value from each visit instead of a polite nod.
What each role actually does
These are two separate volunteer programs, and people confuse them constantly.
Technical Counselor
A Technical Counselor is an experienced builder or mechanic who inspects your work in progress. They look at your welds, your rivets, your control connections, your fuel system. They are not signing off anything legally. They are giving you a second set of trained eyes before you close a wing or bury a wire loom. Their job is to catch the quiet mistakes that pass your own inspection because you have looked at the part a hundred times.
Flight Advisor
A Flight Advisor comes in near the end. They do not touch the airplane. They assess you and your test-flight plan. Are you current? Is your transition training done? Is your emergency plan realistic for this specific aircraft? The Flight Advisor exists because the data has long shown that the early hours of a new homebuilt, flown by an out-of-practice builder, are the riskiest.
Why this matters more than most builders admit
The person most likely to miss a flaw in your build is you. You know your own logic, so you re-confirm it instead of questioning it. A counselor breaks that loop. They ask why a fitting is oriented that way, and half the time the question alone makes you check the plans again.
How to find the right one
Start with your local EAA chapter. Chapters keep lists of active counselors, and a face-to-face meeting beats a cold call. EAA also maintains a counselor directory through its membership resources. When you contact someone, do not just ask for a visit. Tell them your aircraft type, your build stage, and what you are unsure about.
Match the specialty
A counselor who has built three tube-and-fabric taildraggers may be the wrong reviewer for your carbon composite kit. Ask what they have built and inspected. A good counselor will tell you honestly when a project is outside their depth and point you to someone else.
A real scenario
A builder finishing an RV-style kit invites a Technical Counselor before closing the fuel tanks. The counselor notices the fuel vent line routed so a slight sag could trap water at the low point. Nothing was technically wrong per the drawing, but the routing was poor. Ten minutes of rework versus a possible fuel-starvation event at altitude. That is the entire value proposition in one visit.
Common mistakes and how to fix them
- Calling only once, at the end. By then the wings are closed and the wiring is hidden. Fix: schedule visits at natural milestones — before closing structure, after systems install, before first engine run.
- Treating the visit as an inspection to pass. You want them to find things. Fix: hand them your open questions first, then let them roam.
- Confusing a counselor visit with the airworthiness inspection. The counselor has no legal authority. Fix: keep your builder log and plan your DAR or FSDO inspection separately.
- Skipping the Flight Advisor because you fly often. Flying a familiar type is not the same as flying an untested airframe. Fix: book the Flight Advisor and be honest about your recent hours.
Action steps
- Join or visit your local EAA chapter and ask who the active counselors are.
- Confirm the counselor has relevant experience for your construction method.
- Book the first visit before you close any major structure.
- Prepare a written list of your own doubts before each visit.
- Keep photos and notes from every visit in your builder log.
- Contact a Flight Advisor well before your target first-flight date, not the week of.
Conclusion and next step
Counselors and advisors are the cheapest safety upgrade in homebuilding, and both are volunteer programs open to members. Your next step: find your nearest EAA chapter this week and ask for one name in each role. Make the first call before your next big build milestone.
FAQ
Does a Technical Counselor sign off my aircraft as airworthy?
No. They provide advice only. Legal airworthiness certification comes from an FAA inspector or a Designated Airworthiness Representative after your build is complete.
How much does it cost?
The counselor and advisor programs are volunteer-based for EAA members. It is courteous to cover any travel or offer a meal, but there is no service fee.
How many visits should I plan?
There is no fixed number. Many builders schedule three to five visits tied to milestones. More complex or slower builds justify more.
Can I get a counselor if I bought a partially finished project?
Yes, and it is a smart move. A counselor can help you assess unfamiliar work you did not do yourself.
