Automotive Maintenance
Official Requirements & Fillable Workbook · 2026 Edition
Automotive Maintenance is hands-on: you will be under the hood checking fluids, belts, fuses, and brakes on a real vehicle. You need access to a car or truck and its owner's manual before you start. Much of the badge is about knowing what the dashboard is telling you and what the manual already says — two things most drivers never learn.
Key Requirements Covered:
- Shop Safety & Basic Tools
- Engine Systems & Fluid Maintenance
- Tires, Brakes & Suspension
- Electrical Systems & Diagnostic Checks

Two dates, two different things
Requirements Revision vs. Worksheet Date
Scouting America last revised the Automotive Maintenance requirements in 2026. That is the badge, not this sheet — an older year does not mean the worksheet is out of date.
Verbatim Fidelity & Verification
This worksheet was checked against https://www.scouting.org/merit-badges/automotive-maintenance/ in Aug 2026 and reproduces the requirements word for word. Both dates are printed on the sheet, so a copy in a binder can always be placed in time.
Requirement text is © Scouting America, reproduced verbatim. The worksheet layout and design are original to this project.
Nearby badges
Astronomy cannot be finished in a weekend. Requirement 4 wants the Big Dipper or Cassiopeia sketched hours apart, requirement 6 wants the Moon on four nights in a week, and requirement 5 wants a planet chart covering the next 12 months. Start the observations early and record the date and time on every sketch — that detail is part of the requirement, not a nicety.
Key Requirements Covered:
- Night Sky Navigation & Constellations
- Telescopes & Optical Instruments
- Planetary Motion, Moon & Sun
- Cosmology, Stars & Space Science
Athletics is about training your body on purpose. You will pick an activity, build a program around it, stick with it for three months, and measure what changed. Along the way you will learn how to stay out of the athletic trainer's room, what a balanced diet actually looks like, and why sportsmanship matters more than the score.
Key Requirements Covered:
- Conditioning & Injury Prevention
- Sportsmanship & Athletic Rules
- Training Plans & Fitness Tracking
- Competitive Event Assessment
Aviation runs from why a wing lifts to what it takes to hold a pilot certificate. Requirement 2 asks you to build and fly something — a paper FPG-9, a rubber-band balsa plane, or a powered model or drone (which needs TRUST certification). Requirements 3 and 4 involve visits and flights that take arranging, so read ahead and book early.
Key Requirements Covered:
- Four Forces of Flight & Aerodynamics
- Aircraft Instruments & Flight Controls
- Airports, Navigation & Air Traffic Control
- Flight Planning & Aviation Careers
Backpacking is one of Scouting’s most demanding and rewarding badges. You will learn what equipment to carry and how to keep weight down, how to navigate with topographic maps and compass, cook on backcountry stoves, and minimize your impact under Leave No Trace. To earn it, you will plan and carry your pack on three 3-day, 15-mile treks, plus a capstone 5-day, 30-mile trek with a service project and daily journal.
Key Requirements Covered:
- Trail Planning & Gear Selection
- Leave No Trace & Campcraft
- Trail Health, Water & Nutrition
