A part 135 operator's maintenance manual designates the reassembly of the main landing gear retraction mechanism as a Required Inspection Item (RII). What does this designation mean?
- AThe item only requires a logbook entry with no physical inspection
- BThe item is exempt from inspection because it was manufacturer-certified
- CThe item must be inspected by a person other than the one who performed the work, and that person must not have performed the maintenance being inspected
- DThe item may be inspected by the same technician who performed the maintenance
Show answer & explanationAnswer & explanation
Correct answer: C. The item must be inspected by a person other than the one who performed the work, and that person must not have performed the maintenance being inspected
Required Inspection Items (RII), as required under 14 CFR parts 121 and 135, are critical maintenance tasks where an error could result in a hazard to flight safety. These items must be inspected by a qualified person other than the one who performed the work to provide an independent check.
Why the other options are wrong
- A. RII requires a physical inspection, not just paperwork.
- B. Manufacturer certification does not exempt RII items from independent inspection.
- D. This would defeat the purpose of an independent RII check.
Required Inspection Items (RII)
Critical maintenance items designated in an air carrier's maintenance program that require an independent inspection by someone other than the person who performed the work.
- Applies to parts 121 and 135 operations
- Ensures an independent check on flight-critical maintenance
- Inspector must be specifically authorized/qualified for RII duties
Memory trick: RII = a 'second set of eyes' checking critical work
