CARs Explained: The Maintenance Release (CAR 605.85 and 571.10)
TP 14038 lists maintenance release as a REGS exam topic, and it's one of the ideas the rest of Part V hangs on. If you understand the maintenance release, a lot of other rules start to make sense.
What it is
A maintenance release is the signed certification that maintenance was performed to the applicable standards. It's what returns an aircraft (or a part) to service after maintenance. No release, no legal return to service.
Two Parts, one idea
This is a classic "location" topic, because the rule is split across two Parts:
Part VI (CAR 605.85) is the operating side. It's the rule that stops an aircraft that has had maintenance from taking off until that maintenance has been certified with a maintenance release.
Part V (CAR 571.10 and the Standard) is the maintenance side. It covers the release itself: when it can be signed and what it has to include.
CAR 571.11 covers who may sign a maintenance release.
A good memory hook: Part VI says you need one, Part V says how to do one.
What exam questions look like
Expect questions in both of TP 14038's styles:
Application: "After [a given piece of work], which of the following must be done before the aircraft can fly?" or "Which person may sign the release for this work?"
Location: "The requirement for a maintenance release before take-off after maintenance is found in which Part of the CARs?"
Common traps
Mixing up the two Parts. The requirement to have a release before flight is operational (Part VI); the release itself is a maintenance rule (Part V).
Elementary work. Some tasks are classed as elementary work, and the rules on who may certify them differ. Read the elementary work rules alongside the maintenance release rules, not separately.
The release isn't the record. Signing a release and making the technical record entry are related but separate requirements. Study technical records (605) next.
Study it in 20 minutes
Read CAR 605.85 on Justice Laws.
Read CAR 571.10 and 571.11, then the matching parts of Standard 571.
Write one line for each: when is a release needed, who can sign, what must it say.
Do the Part V review questions.
