The maintenance and troubleshooting of ice and anti-ice systems in Boeing 737 aircraft are critical for ensuring safe operations in cold weather conditions. Ice accumulation on key components, such as wings, engines, and sensors, can lead to reduced aerodynamic performance, engine malfunctions, and sensor errors. Effective maintenance practices are necessary to minimize system failures that could contribute to accidents or incidents. This paper explores the primary environmental impacts, including the potential for icing to affect flight safety, and evaluates the effectiveness of current maintenance protocols in preventing system failures. Common troubleshooting techniques are discussed, emphasizing diagnostics and corrective actions to resolve issues like engine anti-ice valve malfunctions, wing anti-ice leaks, or sensor heating failures. The evaluation of past accidents and incidents involving Boeing 737 aircraft due to icerelated failures is analyzed to understand system vulnerabilities and improve maintenance procedures.
