| May 28, 2019 at 17:49 | comment | added | Emrah Ceylan | No at 250 ,it is to left , at 500 to right. | |
| May 28, 2019 at 13:24 | comment | added | Koyovis | So both at 250 and at 500 knots the uncommanded roll is to the left? | |
| May 28, 2019 at 13:10 | comment | added | Emrah Ceylan | Yes we checked all aileron system. The aircraft is t-38 | |
| May 28, 2019 at 13:06 | comment | added | Juan Jimenez | Have you checked the aileron actuating system and associated hydraulic lines? | |
