Level II preservation provides protection for idle/inactive aircraft and components stored for a maximum of how long?

• A. 1 year
• B. 6 months
• C. 2 years
• D. 5 years

Answer: (A)

Level II preservation is used when aircraft or components will be idle for a limited period and needs a protective setup to guard against corrosion, moisture, dust, and lubricant degradation. It provides adequate protection for up to one year, which aligns with typical short-term storage between flights or maintenance cycles. If storage extends beyond a year, the protective measures would likely need reapplication or a more extensive preservation approach to maintain readiness. Shorter durations, like six months, wouldn’t fully account for the time needed before reactivation, while longer, multi-year storage would require more advanced preservation levels.
