Bentley said Cirrus has studied the incidents extensively and determined there are no design or equipment faults at work, and for Cirrus this leaves only "operator error" as the cause. Unlike many aircraft pilots may be transitioning from, Cirruses have a free castering nosewheel and are steered only with differential braking, plus some positive or negative contribution from the rudder (dependant on relative wind). Bentley said some pilots may have a tendency to overuse the brakes to compensate for excessive power settings or may simply be riding the brakes. Last June, the company e-mailed all its customers (click here for a pdf version) with an owner service advisory that warned them not to overtax the brakes, which Cirrus also says are more than adequate for an airplane with the performance and weight of a Cirrus.
