No. A chimp from the waist up, maybe, but the arm bones were human like (much longer, in proportion to a chimp, gorilla or orangutan—human proportioned), and she had a definitive pelvis and long human legs with kneecaps, ending in flat human feet.
What ever Lucy was, she wasn’t a chimp.
Dr. Don Johanson recovered almost all of her skeleton.
I stand corrected as to how much of the individual specimen Lucy’s remain were found, however, several of these creatures were found together at one site, having gone through some catastrophe (flash flood or perhaps volcanic ash flow).
As follows:

The main fossil sample of this species also comes from Hadar, and the specimens found there include a 40-percent-complete skeleton of an adult female (“Lucy”) and the remains of at least nine adults and four juveniles buried together at the same time (the “First Family”). The animal fossils found in association with Au. afarensis imply a habitat of woodland with patches of grassland.
