Required Inspection Items
Some maintenance, done wrong, endangers the aircraft. Designate those required inspections by aircraft type, authorize the inspectors who may sign them off, and let the system enforce the one rule that can never bend — the person who did the work cannot inspect it. Built for 14 CFR 121.369 / 135.427.
The independent check, controlled end to end
RII is performance-based — the regulations give you no canned list. Build and revise yours, authorize the right people, and prove the separation of duties on every sign-off.
RII designation list, per aircraft type
Designate the specific inspection FUNCTIONS that demand an independent check — flight-control rigging, engine-mount torque, gear retention — with the task reference, method, accept/reject limits and revision control your CASS process drives.
Inspector authorization matrix
Track exactly who is authorized to sign off which RII, on which aircraft type, by scope — certificate basis, formal + OJT training dates and the written authorization reference 121.371 requires, with currency that flags before it lapses.
Separation of duties, enforced
The person who performed the work can never inspect it (14 CFR 121.369(b)(7)). The system hard-blocks a same-person sign-off — and extends the rule to anyone who performed corrective rework before a buy-back.
Buy-back, documented to the same rigor
When an RII is rejected, the corrective action is recorded and the item is re-inspected by an authorized, independent inspector — every attempt captured on an append-only timeline.
Sign-off records that survive the audit
Each completion record snapshots the RII, the aircraft, the performer, the inspector and the verdict — a full chain of custody traceable to the individual authorized inspector for 145.219 record retention.
Tied to your work, not bolted on
Reference the work order, job card and task an RII covers, link it to a designation, and keep the whole required-inspection picture beside the rest of your maintenance system.
