FAA Revises VLJ Certification Rules
Because of great strides in aviation technology, the FAA has issued a final rule

Because of great strides in aviation technology, the FAA has issued a final rule that will require function-and-reliability (F&R) flight testing for all turbine-powered airplanes weighing 6,000 pounds or less, beginning on December 19.

Currently, function-and-reliability flight testing is required only for Part 23 certified airplanes that have a maximum certified weight of more than 6,000 pounds. But the FAA said that because of advancements in airplane structures, propulsion methods and systems technologies, the 6,000-pound demarcation is no longer justified.
