In plain language (FlightFinder summary)
The NTSB asks Quad City Ultralight Aircraft Corporation to determine any needed design modifications to ensure that Challenger airplanes configured with floats, skis, or other gear have positive directional stability throughout their operating envelope. It is also asked to make those modifications available as options or accessories, or to provide engineering drawings to owner/builders, and to issue a safety/service advisory letter to all owners/operators recommending they incorporate the modifications.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
