QUESTIONAn aircraft used for hire has a 100-hour inspection that comes due at 1,250.0 hours total time. The aircraft is away from its maintenance base. To what maximum total time may it be flown, if necessary, to reach the destination where the inspection will be conducted?

  1. A1,250.0 hours; no overflight is permitted
  2. B1,275.0 hours
  3. C1,260.0 hours
Show the answer and explanation

Correct answer: C. 1,260.0 hours

  • A — incorrect An overflight allowance does exist for the 100-hour inspection; up to 10 hours beyond the limit is permitted to reach the inspection destination.
  • B — incorrect The allowance is 10 hours, not 25 hours, so 1,275.0 hours would exceed the permitted overflight.
  • C — correct The handbook allows an aircraft to be flown up to 10 hours beyond the 100-hour limit if necessary to reach the place where the inspection will be conducted; 1,250.0 plus 10.0 equals 1,260.0 hours.

BACKGROUND

Aircraft that carry persons for hire or are used for flight instruction for hire must receive a complete inspection every 100 hours. Because such aircraft may be away from their maintenance base when the inspection falls due, the handbook notes that an aircraft may be flown up to 10 hours beyond the 100-hour limit if necessary to fly to a destination where the inspection is to be conducted. This overflight allowance is one of the two significant differences between the 100-hour inspection and the annual inspection, the other being who may perform each inspection.

STUDY TIP

For overflight questions, add exactly 10 hours to the time at which the 100-hour inspection is due and confirm the flight is to the place of inspection.

KEY POINTS

  • A 100-hour inspection may be exceeded by up to 10 hours.
  • The overflight must be necessary to reach the destination where the inspection will be done.
  • Due at 1,250.0 hours means the aircraft may reach 1,260.0 hours en route.
