What's wrong?
The side emergency exit window on 2018-2021 Trans Tech Sstflr, Sst, Cst, and Cstflr school buses is an egress window. Its job is to open after a crash or rollover so passengers and rescuers have another way out. The latch must clear its catch plate, and the window frame must stay rigid enough for the window to move freely.
On the recalled buses, Lippert horizontal hinged egress window part number 510175 was built without upper frame rivets. Those rivets add stiffness to the exterior window frame. Without them, the window can move downward, which lets the latch rub or hang up on the catch plate. In a rollover, that binding can keep the emergency exit window from opening as required.
Owners or fleet staff can look for a window that does not open and close smoothly, or that catches at the latch plate. The exterior top corners of the window frame will be missing rivets.

What happens at the repair
At the dealer, a Trans Tech technician inspects the emergency exit windows and repairs any windows that need repair. Parts and labor are covered under the recall, so the owner and dealer do not pay for the inspection or repair. If you already paid for the same repair before receiving the recall letter, complete the prepaid response card and reimbursement form from the letter, then send it with a copy of the work order or invoice to Transportation Collaborative Inc.
