Part 66 Module Prep Help

Part 66 Module Prep helps you practise for the multiple-choice part of the Part-66 basic knowledge module exams for the B1.1 (turbine aeroplanes) and B1.2 (piston aeroplanes) licence, under the EASA rules or the UK rules. Here are answers to common questions. How the app handles your data is described in the Privacy Policy, and the rules for using it in the Terms of Use. If you still need help, email us (see Contact at the end).

About the questions

• Not affiliated with or endorsed by EASA, the European Union or the UK Civil Aviation Authority. Practice questions are original or adapted from FAA public-domain material, with explanations quoting public documents.
• Answers and explanations are written by us from public documents, not by EASA or the UK CAA. No question in this app is an EASA or UK CAA exam question. The real exam may differ.
• Every explanation quotes its source: a sentence from an FAA Aviation Maintenance Technician Handbook or another FAA handbook (with the document, chapter and page), from EU legislation or EASA material in the EASA Easy Access Rules, or from UK legislation on legislation.gov.uk (with the rule number).
• Topics follow the Part-66 Appendix I syllabus for your licence. A few syllabus topics have no questions yet because no public source covers them.
• The real exams also include essay questions in some modules (EASA module 7; UK modules 7A, 9A and 10). This app covers the multiple-choice questions only.

Choosing your licence

• Choose your licence: EASA B1.1, EASA B1.2, UK B1.1 or UK B1.2. Each shows only its own modules and topics. You can change this later in Settings.
• Module 10 has separate question sets for EU law and UK law.

Free week and plans

• Every feature is free for 7 days from the first time you open the app on a device.
• After the free week, starting practice, review, bookmarked questions or a new practice exam needs a plan: a monthly or yearly subscription, or a one-time Lifetime purchase, sold through the App Store or Google Play. The plans appear when you start one of these.
• To see the plans at any time: Settings › Subscription (the last section) › View plans.
• Without a plan, your progress, your past exam results and their explanations stay available, and a practice exam you already started can be finished.
• To restore a purchase on a new or reset device, or after reinstalling: Settings › Subscription › Restore purchases. Use the same Apple Account or Google account you bought with.
• To cancel or change a subscription:
  • iPhone and iPad: Settings app › your name › Subscriptions › Part 66 Module Prep. Apple's guide: https://support.apple.com/en-us/118428
  • Android: Google Play app › your profile picture › Payments & subscriptions › Subscriptions › Part 66 Module Prep. Google's guide: https://support.google.com/googleplay/answer/7018481
• Deleting the app does not cancel a subscription. Refunds are handled by Apple or Google under their own rules:
  • Apple: https://support.apple.com/en-us/118223
  • Google Play: https://support.google.com/googleplay/answer/2479637
• A Lifetime purchase keeps working offline. A subscription keeps working offline for up to 45 days after the app last confirmed it with the store.
• If your payment is pending, the plan starts when the store completes it.

Practice exams

• Practice exams use the format of Part-66 Appendix II: three options per question, 75 seconds per question and 75% to pass. Each module has its own number of questions, from 20 to 140, so the time depends on the module. Questions are drawn from the module's topics in proportion.
• There is no feedback until you submit. You can flag questions and check all your answers on the review screen before you submit.
• If you leave an exam, your answers are saved and the timer keeps running. If time runs out while the app is closed, the exam is submitted when you open it again. Unanswered questions count as wrong.
• After 2 full-length practice exams in a module, the Study tab shows Ready or Not yet for that module. It is based on your practice results in this app and does not predict your exam result.

Review and bookmarks

• A question you miss comes back for review the next day. Answer it correctly on its review day and it comes back after 3 days, then after 7 days, and then it is done.
• Practice sets have 20 questions: due reviews first, then new ones. Questions due today are also listed in Review.
• Tap the bookmark at the top of a question to save it. Saved questions are listed in Bookmarks.

Reporting a problem with a question

• On a practice question, tap the report button at the top of the screen, next to the bookmark. Choose a reason, add details if you like, and tap Write email.
• This opens your own email app with the question ID, the reason, your note, the start of the question text and the app and question bank versions filled in. Nothing is sent until you press send. If no email app is found, the app copies our email address instead.
• Please do not include questions you saw in a real module exam. Exam content is confidential.
• Corrected questions arrive with app updates.

Language

• Questions, answer choices and explanations are written in English. The app's screens are available in English, Chinese (Simplified), Hindi, Spanish, French, Arabic and Bengali.
• The app follows your device language. To choose a different language for this app, use Settings › Preferences › Language; System default goes back to your device language. The change applies right away and is kept when you reopen the app.
• When the app is in a language other than English, a translation appears below each question, answer choice and explanation to help you study. To turn translations off, use Settings › Preferences › Show translations, or tap Hide translation on a question. Your choice is kept on your device.

Offline and no account

• Questions and explanations are built into the app, so you can study without an internet connection. There is no account, no sign-in and no third-party ads. The app shows cards for other apps by the same developer when you open it and at the top of Settings.
• Your progress is stored only on this device. It is not backed up or moved to a new phone, so a new device starts with a fresh study record. A plan you bought moves with your Apple Account or Google account: use Restore purchases.

Resetting progress

• Settings › Your data › Reset progress deletes your answers, bookmarks, review schedule and exam results on this device, including an exam in progress, and the record of your problem reports. It cannot be undone.
• Resetting does not restart the free week and does not affect a plan you bought.

Usage statistics

To help improve the app, it can send statistics about which screens and features are used (Google Analytics for Firebase). Your answers, notes and name are never sent. In the European Economic Area and Switzerland the app asks first. You can turn this off at any time in Settings › Preferences › Send app usage statistics. Details are in the Privacy Policy.
