A good reminder that it can be the rudder that is mis-rigged and should be carefully checked as well. You may need assistance......

N591ER, a Diamond Aircraft Industries DA42, was conducting a first test flight following a major
refurbishment at Diamond Aircraft Industries at the London International Airport (CYXU). During the
takeoff roll everything appeared to be normal, however as the aircraft nose wheel came off the
ground, and the aircraft became airborne it immediately veered to the left. The pilot attempted to
correct for the un-commanded movement but was having difficulty maintaining direction control of
the aircraft. The pilot declared an emergency and flew the aircraft around for an emergency
approach to Runway 27. During the approach the pilot continued to have control difficulties and
attempted to land on taxiway Alpha, however he ultimately elected to land straight ahead on the
grass. The aircraft touched down hard on the grass breaking off the rudder and the left-wing aileron
mass balance weight. The landing gear collapsed and the aircraft slid approximately 265 feet from
the initial impact to a final stop. The pilot was not injured.

TSB investigators deployed and conducted an examination of the aircraft. The examination found
that the rudder cables had been installed incorrectly.

With all due respect pelmet you post some really interesting information but it lacks details. Please post a date and link or source of the text that you post.

What seems weird to me is why they weren't able to fly without aileron? I have yet to fly a machine that doesn't roll left with left rudder albeit a lot slower and more sluggishly.

The ailerons were operating in the same direction, but the pilot told ATC that the problem was "hard right aileron". The Safety Board said both ailerons were visible from the pilot seat. He might have been too busy to actually look at the ailerons to help diagnose the problem?

If you have this problem, its probably best to keep the ailerons neutral, and use the rudder for directional control.

Aircraft that are frequently disassembled are another area where one needs to be paranoid about ensuring that the flight controls are checked for proper operation......

C-FNYA, an amateur built, DANA motor-glider, departed from runway 27 at the Conn Aerodrome
(CCN4), Ontario for a local flight; the pilot was the sole occupant onboard. Shortly after lift-off, the
aircraft turned to the right, descended, and struck a line of trees bordering a wheat field adjacent to
the airport and subsequently impacted the ground. The aircraft was destroyed, and the pilot
sustained fatal injuries. TSB investigators deployed to the scene. During examination of the flight
control systems, the elevator was found disconnected from the elevator control pushrod. A bolt was
found installed in the elevator control rod end, secured with a washer and a closed coiled tension
safety pin, however the control rod end and related hardware were not connected to the associated
elevator bracket. None of the prementioned components were damaged from impact, indicating the
control rod was most likely not attached prior to the occurrence flight. The horizontal stabilizer and
elevator were designed to be removed easily for storage and transport and were reportedly
installed just prior to the occurrence flight.
