SEOCONTENT-START

OMB Control No.: 2127-0004 Part 573 Safety Recall Report 21V-910 The information contained in this report was submitted pursuant to 49 CFR §573 Manufacturer Name : Ferrara Fire Apparatus, Inc. Submission Date : MAR 16, 2022 NHTSA Recall No. : 21V-910 Manufacturer Recall No. : NR Manufacturer Information : Manufacturer Name : Ferrara Fire Apparatus, Inc. Address : 27855 James Chapel Road PO Box 249 Holden LA 70744 Company phone : 800-443-9006 Population : Number of potentially involved : 25 Estimated percentage with defect : 80 % Vehicle Information : Vehicle 1 : 2021-2022 Ferrara Fire inferno, Cinder Vehicle Type : BUSES, MEDIUM & HEAVY VEHICLES Body Style : OTHER Power Train : DIESEL Descriptive Information : The basis for this recall population is vehicles equipped with a Meritor drive pinion built in a 180 axle series. Meritor provided an affected rear axle serial number list that was cross-referenced with Ferrara Fire’s databases to determine the affected population. Production Dates : FEB 15, 2021 – AUG 11, 2021 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Meritor drive pinion 180 series fractured in the spline. FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : If this condition exists, the fracture of the pinion may hit the brake drop hose which may unintentionally apply parking brake without detection or brake lights coming on, possibly resulting in a crash. Description of the Cause : There was a variation in the pinion spline tooling geometry of the Meritor process. Identification of Any Warning that can Occur : The issue could occur without warning. Involved Components : Part 573 Safety Recall Report 21V-910 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Component Name 1 : Rear Axle Carrior Component Description : Pinion Shaft Component Part Number : 180 series Supplier Identification : Component Manufacturer Name : Meritor Address : 22021 Skyway Church Rd. Maxton North Carolina 28364 Country : United States Chronology : June 2020 – Pinion crack found on campus in Charlotte during a different PSR. August – September 2020 – They completed tests to attempt to replicate and could not reproduce the fracture. Implemented 100% mag particle inspection on all 186R series. Meritor Product Engineering provided a high confidence level that this would be an infancy failure (during the carriers first high load event) due to the fracture signature. April 2021 – Claim created through standard warranty process for pinion crack. July 2021 – Pinion failure during delivery to the dealer from the plant. Facilitated warranty claim through Meritor, they provided new gear set. September 2021 – Houston reached out regarding a pinion crack failure while in service (24 hours in service and under 3,000 miles), was second truck of fleet with similar failure. Pinion broke off and damaged the spring brake air supply line. Metro and Houston insisted an inspection method to validate that the rest of the fleet do not have the same failures. This resulted in Meritor completing an on-site ultrasonic test for the rest of the fleet. Meritor provided corrective action and containment dates, as well as their assessment that this issue is low risk. October 2021 – Spartan risk assessment completed. October – November 2021 – Reviewed past precedence. Reached out to all REV Fire businesses to check for any Meritor pinion warranty issues. E-One had one failure in the field in October 2021 but a different axle series affected. Met with Meritor to review the cause again and the potential affected population. November 10, 2021 – Escalated the issue to REV Group Management. November 15, 2021 – REV’s senior leadership approved a voluntary recall for this issue. Part 573 Safety Recall Report 21V-910 Page 3 The information contained in this report was submitted pursuant to 49 CFR §573 Description of Remedy : Description of Remedy Program : Meritor will conduct an on-site ultrasonic test inspection for the affected population. This will be covered under normal warranty process. Defect units will be replaced at no cost by Meritor. How Remedy Component Differs from Recalled Component : N/A Identify How/When Recall Condition was Corrected in Production : Meritor has implemented containment in their production facility as of April 20, 2021 and corrective action of tooling implementation as of August 2021. Recall Schedule : Description of Recall Schedule : Ferrara to notify Dealers by week of January 3, 2022 and the owners a week later. Planned Dealer Notification Date : JAN 03, 2022 – JAN 07, 2022 Planned Owner Notification Date : JAN 10, 2022 – JAN 14, 2022 * NR – Not Reported
