Structure

ODI #11730308

Incident: March 21, 2024 · Filed: April 10, 2026

1. Component: Bus 15 - Right front outrigger. Yes it is available for inspection 2. Safety: Outrigger cracked creating insufficient support of the school bus body 3. We were told it was not covered under warranty and no recalls have been generated and therefore paid for the first repair through Wolfington Body Co. Inc. Their repair did not hold and it came apart and on 8/7/2024 it was repaired a second time, no charge. It came apart again and on 1/30/2025 it was repaired a third time, no charge. 4. The dealer has inspected the bus, we are not aware of the manufacturer or anyone else having inspected the bus. The dealer did say they were going to present this to the manufacturer but we have never heard anything more about it. 5. We first noticed the crack when we inspected it on 4/4/2024 because we heard and felt an unusual noise/motion when driving on the roads in our town. PLEASE NOTE: Since then we have had a total of 4 out of our 5 International Gas Buses with the identical problem. Those Buses are: Bus 3 The crack was noticed on 10/24/2024 mileage 37,052 cost to repair $3,010.18. This repair came apart again on 10/24/2025 and was repaired on 2/13/26 no charge. Bus 1 The crack was noticed on 11/19/2024 mileage 46,718 the Dealer repaired at no cost due to negotiating a compromise. Bus 12 The crack was noticed on 5/23/2025 mileage 40,310 cost to repair $3,005.58. I have been told by the Dealer's Service Team through an email dated 8/4/2025 that they would be submitting these to the Manufacturers "goodwill process in hopes of having the previous and current repairs reimbursed" To date, we have heard nothing. We strongly feel this is a manufacturer design defect and it must be happening to other IC School Buses as well.
