QUESTIONDuring a 100-hour inspection required by part 91, a mechanic finds an item of equipment that is inoperative but is permitted to be inoperative under § 91.213(d)(2). Under 14 CFR § 43.11(b), what must the mechanic do?

  1. APlacard the item "Inoperative" and add it to the signed, dated discrepancy list
  2. BRemove the item from the aircraft before approving the aircraft for return to service
  3. CLeave the item unmarked, since the operator's MEL already covers deferred equipment
Show the answer and explanation

Correct answer: A. Placard the item "Inoperative" and add it to the signed, dated discrepancy list

  • A — correct § 43.11(b) requires a placard marked "Inoperative" on each such instrument and the cockpit control of each item of inoperative equipment, and the items must be added to the signed and dated list given to the owner or lessee.
  • B — incorrect § 43.11(b) addresses items permitted to be inoperative; it requires placarding and listing, not removal.
  • C — incorrect The regulation requires a placard regardless; § 91.213(d)(2) items must be placarded and listed, and § 91.405 requires inoperative equipment to be placarded.

BACKGROUND

14 CFR § 91.405 requires the owner or operator to have inoperative instruments or equipment properly placarded as inoperative, and § 91.213 sets the conditions under which an aircraft may be operated with inoperative items. Section 43.11(b) of part 43 ties this to inspections: if a person performing an inspection required by part 91 or 125 or § 135.411(a)(1) finds items permitted to be inoperative under § 91.213(d)(2), that person must place a placard meeting the aircraft's airworthiness certification regulations on each inoperative instrument and on the cockpit control of each item of inoperative equipment, marking it "Inoperative." The items must also be added to the signed and dated list of discrepancies given to the owner or lessee. The Aviation Maintenance Technician Handbook–General echoes the § 91.405 requirement that inoperative instruments or equipment be properly placarded.

STUDY TIP

Two actions go together for permitted inoperative items found at inspection: placard the item and its cockpit control, and list it on the discrepancy list.

KEY POINTS

  • § 43.11(b) covers inoperative items found during a required inspection.
  • Each inoperative instrument and the cockpit control of each inoperative item must be placarded "Inoperative."
  • The items must be added to the signed and dated discrepancy list given to the owner or lessee.
