Aircraft Engines & Engine Parts

Aircraft Engines & Engine Parts

The SIC 3724 category covers manufacturers of aircraft engines, turbofans, turboshafts, auxiliary power units, nacelles, and high-value engine parts such as compressors, combustors, turbines, and digital control systems sold to commercial airframers, defense contractors, airlines with in-house maintenance, and MRO providers under long-term power-by-the-hour service agreements. Customers prize fuel efficiency, durability, and fast turnaround, while production is governed by FAA/EASA airworthiness rules, export controls (ITAR/EAR), and strict traceability to mitigate safety, supply chain, and liability risks. In 2024-2025 the sector is accelerating geared turbofan upgrades, sustainable aviation fuel compatibility, predictive maintenance via onboard sensors, and additive manufacturing of hot-section parts, even as tight titanium and rare-earth supplies and ESG scrutiny pressure margins. OEMs are also bundling subscription diagnostics and extended service plans to stabilize revenue.
