Yes, when it is necessary for a permitted vehicle/aircraft to be out of service for routine maintenance or repairs, a substitute vehicle/aircraft meeting the same transport capabilities and equipment specifications as the out of service vehicle/aircraft may be used for a period of time not to exceed 30 days. An unpermitted vehicle/aircraft cannot be placed into service, nor can a BLS vehicle be used at the ALS level unless it is replacing a vehicle that has been temporarily taken out of service for maintenance. When such a substitution is made, the following information shall be maintained by the licensee and shall be accessible to the department:
- identification of permitted vehicle/aircraft taken out of service;
- identification of substitute vehicle/aircraft; and,
- the date on which the substitute vehicle/aircraft was placed into service, the date on which it was removed from service and the date the permitted vehicle/aircraft was returned to service.
