Maintenance of Vehicles Questions
Question #1: Lots of bulbs are being used from stores, yet no DDR reports mention having changed a bulb
Question #2: Lots of bulbs are being changed on PMIs

Question #4: No brake tests are being performed on PMIs
Question #5: Some PMI reports are inadequate; either only bearing one signature (not signed in “all defects repaired” or detailing defects that are being “monitored” or “parts ordered”
Question #6: Recently a PMI report was not available when the driver collected the vehicle and it came through several days later showing an unresolved roadworthiness defect.
