How early can a high-time component be changed under scheduled component changes?

• A. Sixty days
• B. Thirty days or 10% maximum for scheduled component changes
• C. Ten days
• D. Ninety days

Answer: (B)

When a high-time component is scheduled for replacement, you’re allowed to swap it early if needed to maintain reliability, but there are set limits on how far ahead you can do this. The policy gives two bounds: you can advance the replacement by up to 30 days, or by up to 10 percent of the time between overhauls, whichever comes first. In practice, you take the smaller of those two values. So if the scheduled change is 200 days away, 10% is 20 days, and you could replace up to 20 days early. If the change is only 25 days away, you could replace up to 25 days early but not more than 30 days, so the limit would be 25 days in that case. This ensures you don’t over-advance replacements while still allowing proactive changes for reliability.
