Synopsis:
There have been several cases of welds breaking on the overhead-style rudder pedals
(WD-655L and WD-655R) used in the RV-6/6A. These breaks usually occur where the
upright tubes from the pedal connect to the torque tube that runs across the fuselage.
The forward side of the torque tube fails in compression, allowing the aft side of the
torque tube to tear.
Va
n’s Aircraft, Inc. has static tested a set of production pedals and found they exceeded
the strength limits specified in FAR Part 23. However, since several operational failures
have occurred, corrective action should be taken.
