Variants and engines
The maintenance manual's table gives 150 hp and 2150 lb gross for the 108. The 108-1 has 150 hp and 2230 lb. The 108-2 has 165 hp and 2230 lb. The 108-3 has 165 hp and 2400 lb. Check the data plate against these figures, because the manual does not state seat counts or years.
Engine conversions
Service Bulletin 269 (June 11, 1964) covers replacing the original Franklin 6A4-165-B3 with a 180 HP Franklin 6A335-B1. It applies to 108-3 airplanes, serial 108-3501 and up. It needs a new engine mount, propeller governor, cowls and gauges, plus a reweigh and a Repair and Alteration form. Letters also cover a Franklin 165 install on the 108 and 108-1, and converting a 108 to a 108-1 or 108-2.
What to inspect
The Univair bulletin index lists known problem areas: fuel seepage into the cabin, fuel selector valve indexing, rudder cable inspection and misalignment, stabilizer leading edge attachment, cabin sliding window, oleo shock plunger rework, battery and vent tube, wiring harness protection and metal spar splice kits. The manual has daily, weekly (25 hour) and 100 hour inspections.

- Have the rudder cable and stabilizer leading edge attachment inspections done and logged.
- Weight empty is on the airplane's own weight and balance sheets. After any engine swap, require a current reweigh and log entry.
