Advanced Aeromarine Sierra
American glider
The Advanced Aeromarine Sierra was an American high-wing, strut-braced, single-seat, glider that was designed and produced by Advanced Aeromarine, as a kit for amateur construction.
Design and development
The Sierra was intended as a lightweight and affordable glider with modest performance that could be launched by ultralight aircraft aerotow, auto-tow, winch-launch or bungee launch. It first flew in March 1991.
The aircraft was made from aluminium tube, fabric and composites. Its 42.65 ft (13.0 m) span wing was supported by a lift strut and jury struts. The glide ratio was 25:1 and had a landing roll of 150 ft (46 m). The landing gear was tandem wheels, plus a tail caster. The completion time from the factory kit was rated as 150 hours.
Although very light, with a standard empty weight of 205 lb (93 kg), the Sierra did not qualify under the US FAR 103 Ultralight Vehicles regulations as a hang glider, neither was it foot-launchable. Only one prototype had been reported as completed by December 1998.

Why this record matters
“Advanced Aeromarine Sierra” is worth following because a concise public description often conceals a longer documentary argument. Here, Advanced, Aeromarine and Sierra provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 26, 2025. The linked authority identifier is Q2825356. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1991 and 1998.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
