An aircraft had a 100-hour inspection when the tachometer read 1259.6. When is the next 100-hour inspection due?

A

1349.6 hours.

B

1359.6 hours.✓ Correct Answer

C

1369.6 hours.

Explanation

Under 14 CFR 91.409(b) the next 100-hour inspection is due within 100 hours of time in service after the last one, so 1259.6 + 100 = 1359.6 hours. (The 100-hour limit may be exceeded by up to 10 hours only to reach a place where the inspection can be done, and that overflight counts against the next interval.)
