No claim was submitted to Micro Bird in regard with that incident. Without waiting for the conclusion, as a pre-emptive measure, we decided in December 2021 to apply a new method to secure harness and to remove the fuse linked to the main cable of the harness on the production line for all vehicles built on GM chassis. Even though independent investigation had concluded that the causes were not related to Micro Bird, rather pointing to the fact that the final user had installed an A/C system and strobe light after delivery, we decided to review a previous incident where a MY2016 bus, also built on a GM chassis, had caught fire in Augusta, ME in April 2018. This incident had also occurred while the bus was in a parking lot. No claim was submitted to Micro Bird in regard with that incident. On April 21st 2022, it was decided to make the new method to secure the harness permanent and to recall the vehicles built on a GM chassis having the identified harness. We have received no claim regarding thermal incident or fire, nor any other such incident has been reported Part 573 Safety Recall Report 22V-286 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 for vehicles built on GM chassis.
