In this presentation, the pillars of helicopter maintenance - technical precision (following procedures, verifying assemblies and maintaining tool control), human factors and communication (the way that we work together, the way we speak and the way we handle pressure) will be discussed, while exploring real-world case studies where small oversights could have led to major consequences. Attendees will leave this presentation with practical real-world knowledge of best practices. Safety in helicopter maintenance doesn’t depend on perfection—it depends on precision and culture working together.
