Vertical MRO Alerts: By Bell - Ep 6: Main and Tail Rotor Hydraulic Servos

Welcome to Vertical MRO Alerts, presented by Bell!In this Alert, Product Support Engineering Manager Marc Dubé is joined by Sebastien Rousseau, Product Lead for the Bell 429, to walk operators through the recently released Alert Service Bulletin concerning the main and tail rotor hydraulic servos on the Bell 429.This episode explains why the bulletin calls for a one-time inspection of the MCV driver rods, following a supplier notification regarding potential non-conforming components. Marc and Sebastien address the key questions operators have already raised—along with the ones Bell expects to hear. Topics include the reasoning behind the combined 800-hour / 24-month compliance window, guidance for aircraft already undergoing major inspections, and why operators should send servos through Bell rather than directly to the supplier.The discussion also covers expected turnaround times, how unexpected findings can affect lead time, and Bell’s recommendations to help operators minimize downtime.For full details, operators should always refer directly to the official Alert Service Bulletin. The full library of episodes is available to listen to on demandWe want to hear from you! - [email protected] help with your Bell helicopter? - [email protected]
