Description of the Cause : NR Identification of Any Warning that can Occur : Interference between the washer and weld would be visually detectable through pre-flight or PM inspection. Broken rotation bearing fasteners would be detectable through pre-flight visual inspection or PM torque inspection. Involved Components : Part 573 Safety Recall Report 22V-058 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Component Name 1 : Grade 8 Capscrew Component Description : Grade 8 Capscrew Component Part Number : 990365713 Supplier Identification : Component Manufacturer Name : NR Address : NR NR Country : NR Chronology : On July 09, 2021, a Preventative Maintenance inspection of a customer’s LS87 rotation bearing fasteners detected a broken outer race bolt. An examination of the rotation bearing joint on the subject unit identified washers overlapping weld on the pedestal outer race bolts. This overlap resulted in deformation of the washers. Altec issued CSN 833 (21V722) to Notify owners of the affected LS87 units of the possible defect. Investigation into root cause identified the LS60 as also being potentially susceptible to this condition. On November 11, 2021, a field inspection conducted as part of Altec’s investigation of this issue revealed a customer LS60 exhibiting this condition. Altec continued to investigate the frequency and severity of the manufactured condition of LS60 products in the field. On January 17, 2022, a condition similar but of lesser magnitude was identified. On January 28, 2022, after reviewing the investigation results, Altec determined that a defect could exist on LS60 units. There were no other warranty claims identified. There have been no accidents, injuries, or deaths related to this issue.
