If they are not placed exactly 1" apart, there is a chance that the wiring will hang down. If it hangs down the nose landing gear will catch it and rip the wiring.

It is that process which has come under fire at American and is blamed by many pilots for the second MD-80 grounding, says Kevin Cornwell, an American MD-80 pilot from Keller, Tex. "In no way is this a line-mechanic problem. This is a management problem."
At American's Apr. 10 news conference, Arpey said that interpreting an FAA airworthiness directive involves "a great deal of judgment" and that even FAA engineers can disagree about the proper method for certain repairs or changes.

While I appreciate Zaphod's excellent breakdown and he may well be right, I have to agree with Mr. Penny that there are psychological and financial factors that would likely have outweighed the "safety" need to ground all of these planes at once

I notice that everyone is completely ignoring the fact that this all started with Southwest and their 737s. Then there was the first grounding where American WAS allowed to pull them a few at a time, and Delta was grounding them too. Then there were the United 747s that sat for a couple of days while records were checked, and their 52 777s that were grounded.
Let's think about this for half a second here. Which makes a better weapon, the 747 that can hold 500 people and is massive, the 777 that is almost as big and holds 350+, or the MD-80 that is a tiny narrowbody that holds about 130. How come no one has bothered to accuse United, Delta, or Southwest of being infiltrated by terrorists?
Maybe because none of them are? (not even American).

when it comes to MD-80 maintenance American has one of the best crews in the business.
No one, including the FAA, is saying that any of these planes were unsafe to fly. But rather than allow American to ground a few planes at a time and phase in the fixes and re-inspections (as it had done just two weeks earlier), the FAA chose to ground all the planes at once. Source

Let's look at the other major airlines:
Northwest- Widebodies to Singapore and Hong Kong
Jet Blue and America West send their planes to El Salvadore
United Airlines- 777s to Beijing for heavy maintenance
Other airlines outsource almost 50% of their maintenance. The work done on the 777s for United includes stripping the planes down to bare frame, and going over every inch of airframe, every rivet, everything.
