Understanding Canadian Drone Maintenance Documentation

Transport Canada's RPOC (Remote Pilot-in-Command) certification doesn't just require you to fly safelyโ€”it demands proof that your aircraft are safe. Maintenance records form the backbone of that proof.

Piyo: "So we need to keep records of every maintenance check? That sounds like a lot of paperwork."

Moo: "Exactly. Transport Canada treats maintenance records like a legal chain of custody. If an auditor asks 'prove your Mavic 3 is airworthy,' you need documented evidenceโ€”not just your word."

What Transport Canada Actually Requires

The Legal Foundation

Under CARS Part IX (Remote Pilot Operations), RPOC holders must maintain:

  • Pre-flight inspection logs (date, aircraft, pilot name, issues found)
  • Maintenance performed (what was done, by whom, when, serial numbers)
  • Component replacement records (batteries, propellers, cameras, flight controllers)
  • Repair history (defects, corrective actions, test results)

This isn't a suggestion. It's a compliance obligation.

Retention Period

5 years minimum. Transport Canada auditors can request records going back 5 years. Digital storage is acceptable, but you must be able to produce hard copies on demand within 72 hours.

Poppo: "Five years? That's a long time for data storage."

Moo: "But it's non-negotiable. Most RPOC operations involve commercial drone useโ€”agriculture, infrastructure inspection, delivery. One accident claim can drag in regulators looking at your entire maintenance history. Five years isn't paranoia; it's due diligence."

Building Your Maintenance Record System

What to Document (Mandatory)

  1. Aircraft identification โ€” Make, model, serial number, registration mark
  2. Maintenance date & time โ€” Be specific (not "last month")
  3. Maintenance type โ€” Pre-flight check, post-flight inspection, component replacement, repair
  4. Findings โ€” What did you check? What did you find?
  5. Actions taken โ€” How was each issue resolved?
  6. Pilot/technician name & signature โ€” Who did the work?
  7. Flight hours accumulated โ€” Total airtime since last service

What to Track per Component

  • Batteries: Charge cycles, voltage readings, swelling, balancing date
  • Propellers: Visual damage, balance, replacement date
  • Camera/gimbal: Focus test, image stabilization, calibration date
  • Flight controller: Firmware version, calibration history
  • Remote controller: Battery condition, signal loss events

Piyo: "Do we need to track everything in a spreadsheet, or can we use an app?"

Moo: "MmowW integrates a Drone Management Portal that auto-populates maintenance schedules and stores records with Transport Canada compliance built-in. But at minimum, any system that creates a searchable, dated audit trail will satisfy Transport Canada."
