Bombardier jets must update flight manuals to avoid crashing after engine failure

US aviation regulators want Bombardier to update the flight manuals for its BD-700-2A12 airplanes. This change is needed because a partial loss of thrust after an engine failure could cause the plane to drop below its intended flight path during certain landing procedures.

Pilots rely on flight manuals to understand how to operate their aircraft safely under various conditions. This proposed update means that pilots of these specific Bombardier jets will have new, more precise information about how to handle engine failures during complex landing approaches. This reduces the risk of an accident by giving pilots better guidance for a known dangerous scenario.
