EXTRA 200
901 STEERABLE TAIL WHEEL
901.1 GENERAL
To improve taxi and handling quality, the EXTRA 200 can be equipped with an optional
steerable tailwheel. The deflection angle of this tailwheel is arranged by the rudder control
up to plus/minus 30°. Exceeding this deflection the tailwheel has a full-swivel capability by a
release mechanism.
901.2 LIMITATIONS
The operation limitations are not affected due to the use of the steerable tailwheel.
901.3 EMERGENCY PROCEDURES
There is no change of basic emergency procedures with the installation of the steerable
tailwheel.
901.4 NORMAL PROCEDURES
They are no changes for the described normal procedures after installation of the steerable
tailwheel. In addition to the existing normal procedures the light precompression of connec-
tor springs and movement of the rudder have to be checked during the preflight check.
901.5 PERFORMANCE
Changes in flight performance due to installation of the steerable tailwheel are not notice-
able. The given basic performance data under section 5 are still valid.
901.6 WEIGHT AND BALANCE
A change of the running empty weight and resulting C.G. position after installation of the
steerable tailwheel is neglectable, because of minor differences in weight and C/G between
standard and optional steerable tailwheel.
901.7 DESCRIPTION OF THE SYSTEM
The 5 inch tailwheel has a solid rubber tire and is rotatable by means of a wheelfork, which
is connected to a bearing steelsleeve. This steelsleeve itself contains also the release
mechanic, which gives the wheelfork a full-swivel capability exceeding plus/minus 30°
deflection. The steelsleeve is glued into the glasfiberspring, which is bolted to the tail
hardpoint of the aircraft. The steering of the tailwheel is accomplished by a direct mechanic
link (rudder control cable) from the rudder pedals. The steering deflection of the tailwheel is
controlled by the rudder movement and damped by anti shimmy connector springs.
