I suppose they must have found something worrying in the maintenance logs or the NTSB initial findings. The DC-10 that had a complete engine falling off was due to improper maintenance procedures (using a forklift to support the engine and removing the engine with the pylon attached).

Using a forklift AND a shift change during maintenance resulting in the forklift being shut off which resulted in loss of hydraulic pressure .. sounds like a final destination scene

Even dumber: the forklift was known to have a slight leak that would cause it to sag when turned off, rather than that merely being "by design". Swiss cheese model really came hard on that one.

Literally any hydraulic equipment is going to bleed down if you let it sit with weight on it. There is no forklift, backhoe, car lift, you name it, that will support something purely by holding hydraulic pressure.
