26.11.2007 - Dynamic News - As the Dynamic is not yet certified in USA in LSA category (Light Sport Aircraft) the interest was only limited. Because of this, we decided to meet the American market.

To get the certification in LSA category to MTOW 550 kg, we executed spin test in October 2007 on Prievidza airfield. Slovak CAA was supervising during this test. Spin test was flown by Jozef Chupek, our test pilot, who test flew more than 200 of our WT9 Dynamics.

Spin test flights were flown with our standard aircraft; we didn't make any special modifications besides safety elements such as spin recovery parachute and ejectable cockpit. We tried different combinations of weight and CG position, different position of flaps and different engine power setting.

We brought the aircraft into spin from direct flight and from turn with different aileron positions. During the test we strictly adhered to the flight manual specifications for weight, CG position and speed. All spins were easily recovered without the use of drogue parachute just by using normal spin recovery procedures. We are satisfied with the test results not only for American LSA certification. Most of all we are happy, that we have demonstrated reliability and safety of our Dynamic and this is our priority.
