We report preliminary results of a spectral line survey of NGC 7027 in the $\lambda$ 3 mm and 1.3 mm bands using the Arizona Radio Observatory (ARO) 12-m and 10-m telescopes. To a sensitivity limit of $\sim$10-20 mK, we have detected 34 lines, including hydrogen recombination lines and rotational transitions of CN, CO, CCH, CO$^+$, HCO$^+$, and their isotopes.
