100-Hour Inspection
Definition
An inspection required every 100 hours of flight time for aircraft used for hire (instruction or charter). Essentially the same scope as an annual inspection but can be performed by any authorized mechanic.
Why 100-Hour Inspection Matters for Pilots
Regulatory knowledge is heavily tested on FAA and EASA written exams. Understanding 100-Hour Inspection helps you stay compliant with aviation rules and avoid certificate actions. Examiners frequently ask about regulations during oral checkrides, so knowing 100-Hour Inspection inside and out is essential.
Exam Tip
This concept is commonly tested in regulations-related questions on FAA and EASA exams. Make sure you can explain 100-Hour Inspection in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
