What you get

Four tools that cover the written, the oral, and everything in between.

📝

Written test

Practice tests & quizzes

1,000+ questions across General, Airframe, and Powerplant, organised into 42 study units that follow the FAA handbooks chapter by chapter. Every answer — right and wrong — comes with an explanation and the exact reference.

Practice quizzes by unit or subject
Timed simulations that mirror the real test

🎙️

Oral exam

An AI examiner you talk to

A mock DME available at 2 a.m. It asks one question at a time, follows up like a real examiner, and tells you afterwards which topics you'd pass and which need work.

Hands-free voice mode — speak your answers
40 topics from the official Aviation Mechanic ACS
A per-topic debrief with what to study

Quick review

1,400+ flashcards

Four decks — General, Airframe, Powerplant, and IA — sorted into the same lettered ACS sections as the printed boxes. Study a whole deck or pick only the sections you're weak in.

Know what to study next

Every question you answer feeds your dashboard. ChatDME re-ranks your weak areas so your study time goes where it actually counts, instead of re-reading what you already know.

How it works

1
Pick your rating
General, Airframe, or Powerplant — or all three. Tell us where you are and we'll aim the material at it.
2
Drill the written
Work through the study units, take practice quizzes, and run a timed simulation when you're close.
3
Face the examiner
Sit a mock oral out loud, get a per-topic debrief, and walk into the real one having already done it.

Why you can trust the content

Written by a certified A&P

Not a content farm. Every question and card is reviewed and approved by a working airframe & powerplant mechanic before a student ever sees it.

Every answer cites its source

Each explanation points to the exact FAA handbook chapter or 14 CFR section, so you can verify anything — the way a mechanic should.

Current handbooks, ACS-weighted

Built from the current FAA-H-8083-30B/31B/32B handbooks and the Aviation Mechanic ACS, with sections sized to match how the FAA actually distributes questions.

Waiting on a class or a test date? Start now.

Part 147 schools have months-long waitlists and Designated Mechanic Examiners are booked out. Study while you wait — or alongside school — so when your turn finally comes, you pass the first time.

Built for how you're getting your certificate

Part 147 students

Keep pace with class, then out-prepare it. Your school teaches; ChatDME makes sure you test.

Working mechanics & IA candidates

Adding a rating, going for your IA, or staying sharp — study around your shift, not a classroom schedule.

Military transitions

Certifying on documented experience through SkillBridge or after separation? The oral is usually the scary part. Practice it until it isn't.

Exam in English — support in your language. The FAA requires English on test day, so questions stay in English while explanations and debriefs can come in Spanish (más idiomas pronto).

Simple pricing

Start free — the first General study unit, practice questions, sample flashcards, and 10 examiner questions a month. Everything unlocks for $12/month or $89/year, and all four flashcard decks are included. Cancel anytime.
