Most first-time builders discover their worst mistakes only during the airworthiness inspection, when they are expensive and demoralizing to fix. An EAA Technical Counselor exists to catch those problems years earlier, for free. This guide explains what the program actually is, how to find a good counselor, and how to run visits that genuinely improve your project instead of turning into social calls.
What a Technical Counselor Really Does
The EAA Technical Counselor program pairs new builders with experienced volunteers who have built or restored aircraft themselves. They visit your shop, look at your work in progress, and tell you what they see. That is the key distinction: they are not inspectors and they are not signing off on anything. They give advice; you remain responsible for the aircraft.
Because there is no signature and no liability tied to a visit, a good counselor can be blunt in a way a paid inspector cannot. That candor is the whole value. A counselor who has drilled out a few thousand bad rivets will spot a soft or smoking rivet line across the room.
Counselor vs. Flight Advisor
People confuse the two EAA programs. A Technical Counselor helps with building the airframe and systems. A Flight Advisor helps you honestly assess whether your skills and the aircraft match before first flight. Many builders need both, at different stages.
How to Find the Right One
EAA maintains a directory of Technical Counselors searchable by location and by aircraft type. Contact your local EAA chapter first. Chapter members usually know which counselors are active, responsive, and familiar with your specific design.
Type experience matters more than raw hours. A counselor who has built three tube-and-fabric taildraggers may miss subtle problems in a carbon-fiber composite layup. Ask directly what they have built and what they are comfortable evaluating.
Running a Useful Visit
Schedule visits at natural decision points, not randomly. The highest-value moments are before you close a structure permanently: before you rivet a wing skin shut, before you glass over an internal bay, before you paint. Once a section is sealed, a counselor can no longer see inside it.
- Clean the shop and lay out the work so it is visible.
- Write down your specific questions in advance.
- Have your plans, build manual, and logbook open.
- Take notes during the visit, not from memory afterward.
- Ask the counselor to log the visit; EAA records can support your build documentation.
A Real Scenario
A builder assembling an aluminum kit wing invited a counselor before riveting the top skins. The counselor noticed the builder had been setting rivets slightly too hard, leaving a faint crack around several driven heads. On a closed wing this would have been invisible until an eventual failure or a sharp-eyed inspector. Because the skins were still open, the fix was two hours of drilling and replacement instead of cutting a finished wing apart. That single visit paid for a lifetime of EAA membership many times over.
Common Mistakes and How to Fix Them
Calling too late. Builders often wait until the aircraft is nearly done, when nothing can be inspected internally. Fix: start visits early, at the first major structure.
Treating the visit as approval. A counselor’s nod is not certification and carries no legal weight. Fix: understand the advice is educational; you still own every decision.
Getting defensive. Some builders argue with feedback instead of absorbing it. Fix: remember you invited an expert precisely to hear hard truths.
Using only one counselor for everything. Fix: for mixed-material aircraft, bring in a second counselor whose type experience matches the part in question.
Action Checklist
- Join or contact your local EAA chapter.
- Search the EAA Technical Counselor directory by type.
- Confirm the counselor’s actual building background.
- Book the first visit before you close any primary structure.
- Prepare written questions and open documentation for each visit.
- Log every visit and act on the feedback promptly.
Conclusion and Next Step
A Technical Counselor turns a solo build into a mentored one at no cost. The next step is simple: locate the counselors near you through your EAA chapter this week, and schedule a visit before your next structure closes. The earlier you start, the more they can see.
Frequently Asked Questions
Does a Technical Counselor visit replace the FAA airworthiness inspection?
No. The final inspection for an amateur-built aircraft is performed by an FAA inspector or a designated airworthiness representative. A counselor helps you be ready for it, but does not substitute for it.
Is the program actually free?
The counselor’s time is volunteered through EAA. You are expected to be courteous, prepared, and possibly to cover any travel or shared meal, but there is no fee for the advice.
How many visits should I expect?
There is no fixed number. Builders commonly arrange several visits across a multi-year project, timed to major milestones rather than a set schedule.
What if there is no counselor near me?
Some counselors will review photos or video for distant builders, and chapters can sometimes coordinate a visit. It is less thorough than an in-person look but better than building unmentored.
