This webinar will help participants understand the need for global harmonization of aircraft certification requirements. It will discuss proof of structure, casting and operational test criteria among other key elements.
This webinar will help attendees understand the impact of changes to commercial transport aircraft certification process involving gust and maneuver load design and performance requirements. It will also discuss topics such as symmetric maneuvering conditions, structural failures that result in extensive engine damage and permanent loss of thrust-producing capability, and much more.
Why Should You Attend:
FAA tasked the Aviation Rulemaking Advisory Committee (ARAC) through the Loads and Dynamics Harmonization Working Group (LDHWG) and the General Structures Harmonization Working Group (GSHWG) to review existing structures regulations and recommend changes that would eliminate differences between the U.S. and European airworthiness standards, while maintaining or improving the level of safety in the current regulations. This proposed rule is a result of this harmonization effort.This webinar will help attendees understand the impact of changes to commercial transport aircraft certification process involving gust and maneuver load design and performance requirements. It will also discuss topics such as symmetric maneuvering conditions, structural failures that result in extensive engine damage and permanent loss of thrust-producing capability, and much more.
