The general interpretation of that extension is that if you use your month or ten hours, you then deduct that from the next inspection interval. So if your aircraft was due its annual on January 1st at 2000 hours, but the check wasn't started until January 15th and 2007 hours, then your next check would still be due on January 1st the next year and at 2100 hours. In other words, you have the opportunity to extend the commencement of the check, but to benefit from it.
