The FAA has issued an airworthiness directive for the Eclipse 500 jet after an emergency landing at Chicago’s Midway Airport on June 5.
The two pilots and two passengers on board were not injured in the incident, and the airplane was not damaged.
According to the FAA, the pilot slammed the thrust levers of the twin jet to the maximum during a balked landing attempt in wind shear. Apparently the force of the movement exceeded the design limits of the thrust lever switches associated with the engine control system.
In its failure mode, the full-authority digital engine control system defaulted, as it was designed to do, to the last known thrust setting—full thrust for both engines. However, because of the fault, the pilot could not further manage the thrust. In preparation for the subsequent landing, the pilot shut down one engine, which, for an unknown reason, caused the second engine to roll back to idle thrust.
Before the next flight, the AD requires a pilot to conduct a one-time 10-minute inspection of the thrust controls to assure that they behave normally. In addition, Eclipse has already supplied owners two temporary aircraft flight manual supplements and quick reference handbooks changes while the NTSB investigation into the incident continues. The changes caution pilots against slamming the thrust levers with excessive force and provide new procedures for dealing with dual engine control failures.

As the cold weather chills AOPA’s Headquarters in Frederick, many of us are inside generating new resources for flying clubs.
In my house, every Friday night is “Movie Night.” While the movies are rarely educational (I don’t think I learned anything from the Lego Movie), we look forward to the weekly opportunity to spend time together. Why not use the same concept for your Flying Club (with the addition of education, of course)?
AOPA Flying Club Manager Kelby Ferwerda posted the following on the AOPA Flying Club Facebook Page: “Recently I’ve talked with quite a few Flying Clubs about maintaining social activity through the cold winter months. Some clubs host Holliday Parties, others have Potluck Movie Nights. What does your club do to keep members involved during the chilly months?”
