QUESTIONUnder a progressive inspection program, within what period must a complete cycle of all phases be completed?

  1. A12 months
  2. B24 calendar months
  3. C100 hours of time in service
Show the answer and explanation

Correct answer: A. 12 months

  • A — correct The handbook states that a progressive inspection cycle must be completed within 12 months; if all phases are not completed in that time, the remaining phases must be done before the end of the 12th month from when the first phase was completed.
  • B — incorrect Twenty-four calendar months is the interval for altimeter, static system and transponder checks, not for a progressive inspection cycle.
  • C — incorrect One hundred hours is the interval for the 100-hour inspection of aircraft used for hire; the progressive inspection cycle is defined in months, not hours.

BACKGROUND

A progressive inspection program divides the scope and detail of an annual inspection into segments or phases, typically four to six. Completion of all phases makes up a cycle that satisfies the annual inspection requirement, and any single phase may be completed overnight so the aircraft can keep flying. Routine items are done at every phase visit while detailed items are typically done once per cycle. The cycle must be completed within 12 months; if it is not, the remaining phases must be conducted before the end of the 12th month from when the first phase was completed.

STUDY TIP

Associate progressive inspections with the number 12: 12 months per cycle, matching the annual inspection it replaces.

KEY POINTS

  • A progressive inspection splits the annual inspection into four to six phases.
  • A complete cycle must be finished within 12 months.
  • Remaining phases are due before the end of the 12th month after the first phase.
