Preventive Maintenance Every Pilot Should Understand

Even if you’re not a certified mechanic, understanding preventive maintenance helps you fly safer and communicate better with your A&P. Learn to perform a thorough preflight inspection beyond the checklist — look for oil streaks, loose rivets, tire wear, and fuel contamination. Know the importance of oil changes at proper intervals and how to read the oil filter for metal shavings. Understand why fuel sumps matter and what water or debris in the tank signals. Pay attention to tire pressure, brake condition, and control surface freedom. Track your aircraft’s maintenance log and upcoming inspections like the annual and 100-hour. A pilot who understands the machine flies with more confidence and catches problems before they become dangerous.
