Speed Trim System (STS) trimming forward for a few seconds during cleanup = normal
STS trimming forward for 5 seconds = you have my attention!
STS trimming down for 10 seconds during climb = WTF, this isn’t normal do something NOW.
(hold the controls, manual flight and re-trim)
STS trimming down 10 seconds for a second time = RUNAWAY STABILIZER no if’s or but’s.....
(STAB TRIM CUTOUT switches should have been an instinctive ‘go to’, stay in manual flight and land)
Standards and Training at these two airlines should be under the spotlight!
