Handicare accessibility (b)(6), the manufacturer of 2000 series outdoor, sn (b)(4) has completed their investigation into the incident.The manufacturer has performed a full review of the pictures provided from the installation as well as disassembly of the power pack for inspection of internal components.In addition, the trunnion casting was sent for external material analysis by a metallurgical laboratory.Their conclusion is that the pack was misloaded during installation and subsequent reinstallation.The resulting misalignment and excessive forces over time caused a stress fracture of the trunnion casting, resulting in the incident.They also noted that because the installation contains no horizontal rail segments great care would be needed on the part of the installer to avoid a misalignment.Dealer and installer are communicated to reinforce the importance of making sure that the pack is correctly loaded as described in the installation manuals.
