✅ Correct Answer: B: Performance of a scheduled 50-hour inspection as specified in the approved maintenance schedule

Under CAR 571.02, a maintenance release is required after any maintenance that is not a minor scheduled servicing task. A scheduled 50-hour inspection is a maintenance task performed in accordance with an approved maintenance schedule (CAR 571.06) and requires an MR certifying that the work was completed in accordance with the applicable standards. Options A, C, and D are considered elementary work or minor servicing that does not require an MR per CAR 571.02(2).

✅ Correct Answer: D: The owner ceases to be the owner or the legal title to the aircraft is transferred

Per CAR 202.32, a certificate of registration ceases to be valid when the owner ceases to be the owner (i.e., the aircraft is sold or legal title is transferred). A certificate of registration does not expire after 12 months — it remains valid until the owner changes, the aircraft is deregistered, or the owner requests cancellation.

✅ Correct Answer: A: All maintenance schedules must be approved by the Minister before they can be used

Standard 571.03 requires that every aircraft be maintained in accordance with a maintenance schedule that has been approved by the Minister (Transport Canada). While manufacturers provide recommendations, the formal maintenance schedule itself requires ministerial approval to be used in Canadian aircraft operations.

✅ Correct Answer: D: For the life of the component or until the aircraft is permanently withdrawn from service

Standard 571.10 requires that technical records be retained for the life of the component, or until the aircraft or component is permanently withdrawn from service. Records include maintenance releases, work orders, and modification records. This ensures full traceability of every maintenance action throughout the aircraft's operational life.

✅ Correct Answer: C: A damaged or misadjusted downlock spring or actuator mechanism

When hydraulic pressure is normal but the gear does not lock down, the mechanical downlock mechanism is the primary suspect. The downlock spring or mechanical actuator physically holds the gear in the extended position. A failed microswitch affects the indication (lights/warnings), not the actual locking function.

✅ Correct Answer: B: 2.5 times the rivet diameter

AC 43.13-1B Chapter 4 specifies a minimum edge distance (distance from the centre of the rivet hole to the edge of the sheet) of 2.5 times the rivet diameter for a single row of flush rivets on aluminium alloy structures. For a double row, the minimum edge distance increases to 3 times the rivet diameter.

Reference: AC 43.13-1B, Chapter 4, Table 4-1

✅ Correct Answer: C: Replace all affected blades in the stage as a set, or follow the engine manual instructions

Turbine blades with sulphidation corrosion must be handled in accordance with the engine manufacturer's manual. Depending on the extent of corrosion, the manual may require replacement of all blades in a stage as a set to maintain dynamic balance and aerodynamic consistency. Blending is generally not permitted on turbine airfoils with structural corrosion damage.

✅ Correct Answer: A: Low engine oil pressure

Constant-speed propellers use engine oil pressure to move toward fine pitch (low pitch/high RPM) and centrifugal counterweights or springs to move toward coarse pitch/feather. If the propeller will not feather but unfeathers normally, it suggests insufficient oil pressure to overcome the feathering spring force. The governor feathering valve solenoid is electrical — if seized, it would affect both feathering and unfeathering.

✅ Correct Answer: C: Perform a bonding and grounding check of the radio rack and airframe ground path

When the antenna system checks out but the radio is intermittent, intermittent bonding or grounding of the radio rack is a common cause. A poor ground path can cause erratic behaviour as vibration and temperature changes affect the connection. Checking the radio rack's bond to the airframe ground (typically less than 2.5 milliohms per MIL-STD-464) should be done before swapping components.

✅ Correct Answer: B: Remove the cylinder, inspect the valve and seat, lap or replace as necessary, and reassemble per the engine manufacturer's instructions

When differential compression shows leakage confirmed through the exhaust valve, the correct procedure is to remove the cylinder for inspection. The valve and seat must be inspected for burns, pitting, or carbon buildup. Depending on the condition, lapping the valve or replacing the valve/seat may be required. Reassembly must follow the engine manufacturer's instructions (torque values, ring gap, etc.). Option A is incorrect because replacing only one cylinder without inspecting the root cause is incomplete maintenance.
