Blown hose again
My dads 06 f250 has blown the power steering hose again within a year of the last one. 
About the same time last year. He said on start up it started whining really loud and then he noticed fluid on the ground. Temp was only 6f. Wondering he should push for a new pump with this happening twice within a year. All the fluid was changed when the new hoses were put on. Any suggestions welcome. Thanks.

The pump is probably strong, but there is a blockage somewhere else in the system. I would assume on the pressure side, thinking that the pressure required to pop a crimped fitting should overwhelm a barbed/clamped fitting. If he can get it under warranty I would go ahead have the gear box replaced.

If it's only whining when cold, try a different fluid. Unfortunately, I think most fluids will be thick until they warm up. I notice when the temps are below 50, I hear a whine and my steering is a little stiffer. I am using Royal Purple ATF, I don't know what might work better, but it's been good for me.

Sounds like the pump bypass valve is not opening.
There is a bypass valve that should open up when the pressure gets too high.
For my 2001, "relief pressure" (pressure at which the pressure relief/bypass valve opens) is 1450-1530 psi.
If it's blowing the hose, the bypass is probably not opening.
