For how long must the record of a 100-hour inspection be kept?

• A. For three years.
• B. For one year or until the next 100-hour inspection is completed.
• C. Indefinitely.
• D. One month.

Answer: (B)

Maintenance recordkeeping for a 100-hour inspection is kept for one year or until the next 100-hour inspection is completed, whichever comes first. This ensures there is a traceable history showing that the required inspection was performed and that the aircraft remains airworthy between 100-hour intervals. If the next 100-hour occurs sooner than a year, you hold onto the record until that inspection is done; if the next one is more than a year away, you retain the record for about a year and then it’s no longer required. This avoids keeping records for too long and ensures you have documentation during the relevant interval.
