Used to, but not any more. Nose wheel on ground is required prior to deploying reversers for MD80 & MD90 aircraft at AA.
B727, B747, B757, B767, MD80, MD90 and F100 are all _capable_ of deploying reversers with main mounts only on the ground. I do not recall AA's DC10s having anything that prevented reverser deployment prior to nosegear touchdown, but I haven't been on that bird in 13 years.
