DIVISION IConstruction Inspection
| Item | Requirements |
|---|---|
| 1 | Identification from material test certificates, before construction is commenced, of materials to be used, including welding metal, for the following parts:
|
| 2 | Verification 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. |
| 3 | Inspection of welds, including non-destructive test examination and verification of any required heat treatment process in accordance with rules or codes. |
| 4 | Verification of rotor balance and thermal stability testing in accordance with rules or codes. |
| 5 | Identification of components from component inspection certificates and inspection of components and their installation. |
| 6 | Witnessing of hydrostatic pressure tests of components in accordance with rules or codes. |
| 7 | Inspection of the constructed engine and witnessing of the engine operation under test. |
DIVISION IIInstallation Inspection
| Item | Requirements |
|---|---|
| 1 | Verification of correct alignment of securing arrangements. |
| 2 | Verification of correct adjustment and operational condition of the connection of the engine to associated systems. |
| 3 | Verification of correct adjustment and operational condition of safety, control and monitoring devices. |
| 4 | Verification 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. |

| 3 | Speed-regulating governors and other safety devices. |
| 4 | Attached pumps. |
| 5 | Compressors, combustion chambers, heat exchangers, air inlet, fuel and exhaust, and starting system for a gas turbine engine. |
| 6 | Engine structure and fastenings without dismantling if a general examination shows that the condition of the components is adequate for further service. |
| 7 | No 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
| Item | Requirements |
|---|---|
| 1 | For gas turbine engines and steam turbine engines, at intervals not exceeding 5 years. |
