Why Not Metal Locknuts Everywhere?

Anybody know the rationale for using nylocs? Why not use the metal locknuts everywhere? Seems like all-metal are less likely to deteriorate/melt over time.
 
The metal ones are lighter and more expensive. The cost difference is not minor. Using them in the entire plane will save nearly a pound, I'd think, though.

Because they are more expensive and unnecessary. Without exposure to serious heat, that plastic does not melt or break down. They do their job for many decades. FF is the exception.

The metal lock nuts chew up the threads of the screws/ bolts.
Good for the engine compartment where one doesn't need many on/ offs, but for the whole plane? seems overkill. JMHO

+1, with one addition. Brake attachment bolts, and maybe main gear wheelpant bracket attachment bolts, should get all metal locknuts as well. Heat from KE dissipation could conceivably melt nylocs in that area as well. Same rationale as that for using viton o-rings on the brake pistons.
