Final answer:
Upon discontinuation of a progressive inspection program, the next 100-hour inspection is due either at the remaining time to the next 100-hour interval or within 10 days, whichever occurs later.
Explanation:
When a progressive inspection program is discontinued, the next 100-hour inspection is due within the remaining time to the next 100-hour interval that was previously used in the progressive inspection schedule or within 10 days, whichever occurs later. This is governed by aviation regulations which stipulate that upon termination of a progressive inspection, the 100-hour inspection timeline must be reverted to the standard timeline required. It does not necessarily have to be done immediately (option A), but the aircraft cannot continue in operation past 10 days without complying with the standard 100-hour inspection, assuming that it is not already due sooner based on the previous inspection schedule.
