Engine certification and integration: CS-E, Part 33, containment, ingestion and installation
How a turbine engine earns its type certificate and is installed safely: the CS-E and Part 33 structure, the safety analysis, blade containment and life-limited parts, bird, hail and ice ingestion, the endurance and block tests, powerplant installation and uncontained rotor failure, ETOPS and continued airworthiness. Part 3 of the Propulsion engineering series.
What you will be able to do
- ✓ Explain how an engine is certified on its own against CS-E and 14 CFR Part 33, and classify failure effects with the engine safety analysis.
- ✓ Describe blade containment and the blade-off test, and how life-limited parts, manufacturing control and damage tolerance protect rotor integrity.
- ✓ Build a bird, hail and ice ingestion test matrix from the inlet areas and the § 33.76, § 33.77 and § 33.78 tables.
- ✓ Plan the endurance and block-test campaign and check it against § 33.87 and the related tests, including the 2025 CS-E changes.
- ✓ Apply the powerplant installation rules, the AC 20-128A fragment models and risk goals, and the fire-zone and reverser requirements.
- ✓ Relate ETOPS type design, airworthiness directives and official investigation findings to engine certification, and connect this part to the series.
Course content

Who this course is for
- Propulsion, powerplant and certification engineers at engine makers, nacelle and aircraft manufacturers and design organisations who plan engine tests or installation compliance
- Powerplant and continuing-airworthiness engineers at operators and MROs who work with life-limited parts, engine airworthiness directives, ETOPS and installation changes
- Airworthiness and compliance specialists who need to read CS-E, 14 CFR Part 33, the Part 25 powerplant subpart and AC 20-128A with confidence
You need: How gas-turbine engines work, or Parts 1 and 2 of this series, or equivalent engine knowledge; comfort with percentages, simple probabilities and basic trigonometry.
