PRACTICAL PROJECT PLAYBOOKSHEET METAL

Plan the job before you touch the aircraft.

Use one disciplined sequence for the assignment, the data, the work, and the explanation.

01 · PREPAREClarify the assignment, article, data, tools, material, and acceptance criteria.

02 · PERFORMFollow the approved sequence and control damage, contamination, and configuration.

03 · INSPECTCheck dimensions, security, condition, function, and conformity to the selected data.

04 · EXPLAINDescribe what you did, why it is acceptable, and what record or approval follows.

EXACT-DATA BOUNDARY Final limits and procedures come from the current data for the assigned aircraft, engine, propeller, or component.

Built for the route you are taking

However you earned eligibility, walk in ready to explain the work.

Use the system beside the training and experience you already have. It turns class notes, shop knowledge, and written-test feedback into focused oral and practical preparation.

Part 147 student

Turn class topics into spoken practice, then focus with your AKTR.

Filter the matching subject after class, answer before you flip, and bring the stubborn misses back to your instructor. After the written tests, use your AKTR codes to focus the next round.

Military maintainer

Translate hands-on experience into FAA terms and project explanations.

Connect what you already know to ACS terminology, civilian privileges, records, and source references. Use the Playbook to rehearse a clear, safety-minded project explanation.

Work-experience path

Practice the systems your day-to-day work rarely covers.

Study around shifts with Quick 10 and saved progress. Build a mixed weak-area stack, then follow the citation when an unfamiliar subject appears instead of memorizing an unsupported shortcut.

Testing soon or retesting

Start with your AKTR, then run balanced Mock Orals.

Start with your documented weak codes, then run balanced oral sessions across subjects. The goal is a stronger explanation, not a guess about the exact question your examiner will ask.

Built to work with your instructor.

Use CertWrench alongside your instructor and hands-on training. For aircraft-specific work, follow the current data for the assigned article.

Questions before you buy

Should I buy Complete or one rating?

Choose Complete if you still need two or all three ratings. Choose an individual rating if it is the only rating you need now.

Can I upgrade from one rating later?

Yes. Email support@certwrench.com from the address used for purchase. We will credit eligible individual-rating purchases toward the $49 Complete system with a private, single-use checkout code.

Does this prepare me for the written tests?

No. It is designed for oral and practical preparation. The flashcards teach many of the same technical subjects, but they are not a multiple-choice written-test question bank.

What does the AKTR Study Plan do?

It reads the Knowledge codes from a PDF or photo of your Airman Knowledge Test Report, lets you confirm them, and opens the matching study topics. Your report is processed on your device. The plan is a starting point, not a prediction of the exact oral questions or practical projects you will receive.

Can I print every flashcard?

Yes. Every purchase includes a duplex print-at-home PDF containing every flashcard in the rating or Complete system you purchased. No manufactured flashcards are shipped with the digital product.

Do I have to study online?

No. You can print every purchased flashcard and study offline. Browser access is included when you want search, filters, oral sessions, AKTR tools, and saved progress.

How was the material reviewed?

Published answers were checked against the applicable FAA ACS, handbooks, regulations, and cited source excerpts. Every flashcard shows its source. The answers are fixed rather than generated during a study session. This is not a claim of FAA approval or independent mechanic endorsement.

What is the refund policy?

Email support@certwrench.com within 30 days for a full refund. Include the address used for purchase.
