QUESTIONA 14 CFR part 147 aviation maintenance technician school offers both the airframe and the powerplant rating. As described in the handbook, each rating alone requires 1,150 curriculum hours, of which 400 hours are general subjects that apply only once to a combined program. What is the minimum combined curriculum for both ratings?

  1. A2,300 hours, the sum of both ratings
  2. B1,550 hours
  3. C1,900 hours
Show the answer and explanation

Correct answer: C. 1,900 hours

  • A — incorrect 2,300 is only the implied total before removing the duplicated 400 hours of general studies.
  • B — incorrect 1,550 is 1,150 plus 400, which adds a second block of general studies instead of the 750 rating-specific hours of the second rating; the combined figure is 1,900.
  • C — correct The handbook computes 1,150 x 2 = 2,300 hours, then subtracts the 400 general-studies hours that are counted only once, giving 1,900 hours.

BACKGROUND

14 CFR part 147 defines the requirements for obtaining an aviation maintenance technician school certificate, which may cover airframe, powerplant, or both. The Aviation Maintenance Technician Handbook–General states that the minimum curriculum for either the airframe or the powerplant rating taught independently is 1,150 hours, and that 400 of those hours are devoted to general studies. When a school offers both ratings, only one set of general studies hours applies, so the handbook subtracts 400 hours from the implied total of 2,300 hours (1,150 times 2) to arrive at the combined minimum of 1,900 hours. The part's appendices detail the curriculum requirements and the general, airframe, and powerplant subjects.

STUDY TIP

Work the arithmetic the way the handbook does: double the single-rating hours, then remove the duplicated general-studies block.

KEY POINTS

  • A single airframe or powerplant curriculum is 1,150 hours.
  • 400 of those hours are general studies, counted only once in a combined program.
  • The combined airframe and powerplant minimum is 1,900 hours.
