Replacement of an Obsolete Absolute Pressure Sensor in an Engine Electronic Control Unit

Abstract

This project analyzed the replacement of an obsolete absolute pressure sensor in an Engine Electronic Control (EEC) system used in aerospace applications. The obsolescence of the absolute pressure sensor created a supply continuity risk that could impact production. The project implemented a PMBOK-based project management framework to coordinate technical evaluations, qualification testing, and configuration updates. Results demonstrated that the selected replacement sensor met form, fit, and function requirements, maintaining EEC performance and certification standards. The work ensured production continuity and compliance while mitigating risks related to obsolescence.
