0344:27 (44:49) HOT-2 yes trim
0344:28 (44:50) HOT-1 there is something wrong there are some problems
0344:43 (45:05) HOT-2 direct Pokeg

0344:54 (45:16) HOT-1 let's check their circuit breakers
0344:55 (45:17) HOT-2 yes
0344:57 (45:19) HOT-1 alternate is correct
0344:59 (45:21) HOT-2 the alternate one is correct
0345:04 (45:26) HOT-1 as aircraft was not flying and on ground something happening is usual
0345:07 (45:29) HOT-1 such as elevator asymmetry and other things
0345:11 (45:33) HOT-1 we don't believe them
0345:23 (45:45) CAM-3 shall I reset its circuit breaker
0345:24 (45:46) HOT-1 yes reset it
0345:25 (45:47) CAM-3 to understand the reason
0345:27 (45:49) HOT-1 yeah
0345:28 (45:50) CAM ((sound of aircraft overspeed warning))
0345:30 (45:52) HOT-1 okay it's no matter
0345:39 (46:01) HOT-1 pull the airspeed we will see
0345:39 (46:01) CAM ((overspeed warning stops))
0345:40 (46:02) HOT-2 now it is three hundred and fifty yes
0345:47 (46:09) HOT-1 let's take that like this
0345:50 (46:12) CAM ((sound of four warning alert tones))
