The lower step on ±he Black Hawk's
±ail rotor pylon can suddenly rotate
and cause a bad spill if the detent pin
in the s±ep²s ±Ube is badly worn. And
if somebody's groin catches the
second s±ep during a fall-ouch!
So eyeball and tes± the deten± pin
on the ±ube asseMbly often³ If the
pin's worn and won't stay in t´e
pylon fitting when you push on the
step, report itµ
Test the pin like so:
•
Pull ±he step oUt and lock it in
position.
•
With both hands¶ pUsh down
and ±oward t´e nose of t´e aircraft.
If it holds, it's
OK.
But if the step gives· get ±he tUbe
assembly replaced. Better to be safe
than sorry¸
