PART III(Subsection 12(2))Construction and Installation Inspections

DIVISION IConstruction Inspection

ItemRequirements
1Identification from material test certificates, before construction is commenced, of materials to be used, including welding metal, for the following parts:
  • (a) turbine cylinder assembly, including covers, discs, nozzles, blades and bolts;

  • (b) turbine rotor assembly including discs, blades and bolts;

  • (c) valves, pipes, couplings, clutches, bearings and bolts;

  • (d) compressor cylinder and rotor assembly for a gas turbine; and

  • (e) combustion chamber and heat exchanger for a gas turbine.

2Verification that welding was carried out by welders certified by a Provincial Government of Canada, or another authority having similar standards where the welding was carried out outside Canada, for the class of work to be done.
3Inspection of welds, including non-destructive test examination and verification of any required heat treatment process in accordance with rules or codes.
4Verification of rotor balance and thermal stability testing in accordance with rules or codes.
5Identification of components from component inspection certificates and inspection of components and their installation.
6Witnessing of hydrostatic pressure tests of components in accordance with rules or codes.
7Inspection of the constructed engine and witnessing of the engine operation under test.

DIVISION IIInstallation Inspection

ItemRequirements
1Verification of correct alignment of securing arrangements.
2Verification of correct adjustment and operational condition of the connection of the engine to associated systems.
3Verification of correct adjustment and operational condition of safety, control and monitoring devices.
4Verification of reliability and sufficiency under trials up to full power under normal working conditions for a suitable endurance period of not less than 2 hours, taking into consideration the size and the complexity of the gas turbine engine or steam turbine engine.

PART IVPeriodic General and Special Inspections

DIVISION I(Section 19)Periodic General Inspection

ItemRequirements
1Operational condition of the engine.
2Correct adjustment and operational condition of safety devices.
3Locations where fluid leakage, metal wastage, overheating, heavy vibration or excessive bearing clearance may occur.
4Correct adjustment of controls and monitoring systems.
5Operational condition of alarm systems, particularly where the engine is designed for non-continuous local supervision.

DIVISION IIPeriodic Special Inspection

SUBDIVISION I(Subsection 20(1))Parts to be Inspected
ItemRequirements
1Casings, glands, nozzles, blades, valves and valve mechanisms.
2Rotors, blades, couplings, thrusts, bearings and bolts.
3Speed-regulating governors and other safety devices.
4Attached pumps.
5Compressors, combustion chambers, heat exchangers, air inlet, fuel and exhaust, and starting system for a gas turbine engine.
6Engine structure and fastenings without dismantling if a general examination shows that the condition of the components is adequate for further service.
7No inspection is required for speed-regulating governors and other complex mechanisms where written information is provided to the inspector by firms specializing in the reconditioning of those mechanisms, indicating that the parts are in good order and adjustment.
SUBDIVISION II(Subsection 20(2))Intervals
ItemRequirements
1For gas turbine engines and steam turbine engines, at intervals not exceeding 5 years.
2Notwithstanding item 1, the first lifting of the casing and rotor of a steam turbine engine that has more than one propulsion ahead turbine with an emergency crossover arrangement is deferred until the engine is 10 years old if the inspector is satisfied that the turbine is in good operating condition based on the records of the vibration indicator, the rotor position indicator and the turbine operation.
