The term sheet is posted, go have a look:

Certainly concessionary compared to the current APA contract, and pretty bad even compared to the current LCC craptastic contract. A few things stick out at me, 4:1 trip rig, no duty rig, PBS, no monthly guarantee for lineholders, no guarantee protection for reserves who call fatigued, Sick leave is a sad joke (really sad... call in sick more than twice a year, get paid at 60% and report to an "accredited absence management vendor"), scope gutted letting loose the flood of 88 seat RJ's, truly unlimited codeshare.
Does seem a bit like the devil is asking for your soul in exchange for that pot of gold.
The Term sheet you linked to is the Term sheet of the proposed contract between American and APA. The one American is trying to force in court. Not the US Airways and APA agreement.
