Maintenance LOSA


A Line Operations Safety Audit (LOSA) is a proactive, formal process that requires expert and highly trained observers to observe operations in real-time and to collect safety-related data on environmental conditions, operational complexity, and human performance in the maintenance facility. Numerous threats exist in the maintenance environment. These threats can emanate from lack of resources, pressure, procedures, and more. LOSA is an ideal way to identify these threats and understand aircraft maintenance crew responses. LOSA also reveals how errors and undesired states are managed by the crews.

LOSA is confidential and nonpunitive and is not a compliance audit. LOSA is conducted by a non-threatening company employee (typically another maintenance technician) who takes notes on what is happening during the course of normal maintenance activities. Once all the data are collected, then a report is written and recommendations are made to management to both reinforce the positives and improve the negatives. LOSA enables organizations to manage threats and errors so that those threats and errors do not turn into accidents and incidents in the future. With LOSA, you are being predictive—which is the ultimate form of proactive safety!
