The Transportation Safety Board (TSB) labs near the Ottawa Airport play a key role in investigating marine, pipeline, railway, and aviation accidents. The TSB determines if mechanical, electrical, material, structural or other deficiencies contributed to accidents by analyzing information from data recorders ("black boxes"), electronic equipment as well as field photographs and site surveys; this helps to piece together the sequence of events leading to an accident. Visitors can view items related to investigations such as equipment to examine materials, electronic systems, and the flight recorder analysis area.
