  3. CA field approval issued by the local FSDO
Show the answer and explanation

Correct answer: B. Acceptable data, such as the manufacturer's maintenance manual

  • A — incorrect Approved data is what major repairs and major alterations require; FAA-approved service bulletins are listed as examples of approved data, not as a requirement for minor work.
  • B — correct The handbook states that minor repairs and alterations need only refer to acceptable data, such as manufacturers' maintenance manuals or AC 43.13-1, and can simply be recorded as a logbook entry.
  • C — incorrect A field approval is requested for a major repair or alteration that lacks previously approved data; it is not needed for minor work.

BACKGROUND

FAA-H-8083-30B chapter 2 explains that the third question a technician must answer before maintenance is what type of documentation substantiates the work. Minor repairs and alterations need only refer to acceptable data, such as manufacturers' maintenance manuals or Advisory Circular (AC) 43.13-1, and the action can simply be recorded in the maintenance record as a logbook entry. Major repairs and alterations require approved data; examples include AD notes, STCs, TCDS, DER-specific delegations, and FAA-approved manufacturer service bulletins. When no previously approved data exists for a major repair or alteration, the technician may request a field approval from the FAA on FAA Form 337.

STUDY TIP

Pair the terms: minor goes with acceptable data and a logbook entry; major goes with approved data and FAA Form 337.

KEY POINTS

  • Minor repairs and alterations require acceptable data.
  • Manufacturers' maintenance manuals and AC 43.13-1 are examples of acceptable data.
  • Major repairs and alterations require approved data such as ADs, STCs, and the TCDS.
