The Loehle SPAD XIII is an American single-seat ultralight aircraft scale replica of the First World War SPAD XIII fighter produced in kit form by Loehle Aircraft for amateur construction.
The aircraft meets the requirements of the US FAR 103 Ultralight Vehicles regulations when equipped with a lightweight engine.Cliche, Andre: Ultralight Aircraft Shopper's Guide 8th Edition, page B-44.

Design and development
The SPAD XIII is built predominantly from riveted aluminum tubing and stainless steel gussets and stamped aluminum wing ribs, all covered in doped aircraft fabric. The landing gear is of conventional configuration, with a tail skid. For scale requirements the cockpit is only {{convert|18|in|cm|0|abbr=on}} wide.
The standard engine recommended for the design is the out-of-production {{convert|28|hp|kW|0|abbr=on}} Rotax 277, with the also out-of-production {{convert|35|hp|kW|0|abbr=on}} Rotax 377 as an option. Other recommended engines include the {{convert|40|hp|kW|0|abbr=on}} Rotax 447 and 2si powerplants, both also out of production. Kit options include brakes and a long-range fuel tank.
The initial aircraft in the line is a scale replica of the First World War SPAD XIII. The same basic airframe has been developed, though the use of different rudders, wingtips, cowlings and other minor cosmetic differences, into replicas of other First World War fighter aircraft.
Reviewer Andre Cliche says about the SPAD XIII, that it "looks like a museum piece. But imagine that you can fly this museum piece and feel what the WWI pilots felt when they flew their war machines."
Reviewers Roy Beisswenger and Marino Boric wrote in a 2015 review, "the kit is very complete and builder-friendly, leaving you only the fabric covering, the paintwork and the fitting of the engine and instruments before you take off for your dawn patrol."Tacke, Willi; Marino Boric; et al: World Directory of Light Aviation 2015-16, page 115.
