Early Corrosion Prevention and Control (CPC) planning is critical for reducing aircraft life‑cycle cost (LCC). A large share of total ownership cost (TOC) results from operation and maintenance, so systems enabling early corrosion detection can significantly improve cost efficiency. A pilot integration of a Corrosion Health Monitoring (CHM) subsystem into the Structural Health Monitoring (SHM) architecture was conducted on a Mi‑17 helicopter in service with the Polish Armed Forces. The solution uses Luna Acuity LS sensors, compact autonomous multi‑sensor units capable of long‑term measurement of environmental and corrosion parameters, including air temperature, relative humidity, surface conductance, and both free‑corrosion and galvanic‑corrosion currents. Two Acuity LS units were installed in high‑risk locations: beneath the cabin floor in the lowest part of the fuselage and near the main gearbox, where fluids and moisture are likely to accumulate. Data are internally logged and periodically retrieved for analysis, allowing early identification of corrosion‑prone conditions. Initial results demonstrate improved detection of corrosion processes, fewer manual inspections, and shorter maintenance downtime, leading to measurable reductions in operational and support costs. Integrating CHM with SHM using Luna Acuity LS sensors is a promising method to support CPC strategies and optimize LCC for helicopter fleets.
