Technical Order (TO) 11A-1-10 Inspection Practice Test

In inspection practice, defects are grouped by how serious they are to safety and function. There are three classifications: Critical defects pose an immediate safety hazard or could prevent the item from performing its essential function and require immediate action; Major defects are significant and could impair function or safety, needing timely repair but not necessarily stopping work right away; Minor defects are less serious, often cosmetic or unrelated to immediate safety, and are tracked for correction later. This three-tier system is why the correct option lists three classifications by name: Critical, Major, and Minor. Options proposing only two classifications omit the urgent, safety-related category; one option adds a non-existent fourth category; another repeats categories, which isn’t how this guidance defines them.
