Results are presented from a pilot survey of 3.3 micron PAH emission fromplanetary nebulae using FLITECAM, an instrument intended for airborne astronomywith SOFIA. The observations were made during ground-based commissioning ofFLITECAM's spectroscopic mode at the 3-m Shane telescope at Lick Observatory.Direct-ruled KRS-5 grisms were used to give a resolving power (R)~1,700.Targets were selected from IRAS, KAO and ISO sources with previously observedPAH emission at longer wavelengths. AGB stars and PN with C/O ratios < 1 werealso added to the target list in order to test PAH detection thresholds. Inall, 20 objects were observed. PAH emission was detected in 11 out of 20observed targets.
