<h1>Uncommanded Ram Air Turbine Deployment on Widebody Raises Safety, Regulatory and Liability Questions After Preliminary Internal Findings</h1> An airline reported that preliminary internal investigations found the uncommanded deployment of the ram air turbine (RAT) on a long-haul widebody during final approach was neither caused by a system fault nor pilot action, and that electrical and hydraulic parameters remained normal; the regulator was notified and the preliminary report submitted. A pilot association urged grounding of the carrier's fleet of the affected type, electrical-system inspections and a special regulatory audit; the carrier grounded and inspected the aircraft and returned it to service. The occurrence and a recent fatal crash involving the same aircraft type raise potential regulatory, operational safety and liability issues.
