Superior Air Parts has settled the lawsuit stemming from a 2016 crash of a Van’s RV-8A experimental following catastrophic failure of the XP-400 engine. The Dallas Morning News is reporting that Superior settled for $5 million in the crash of builder/owner Dane Sheahen and passenger James Kos in March of 2016; both men were killed in the accident. Last March, Superior stopped selling the XP-400 (and the XP-382) and began a buyback program to get the engines out of circulation. At the time, Superior had ruled out material issues and was focusing on possible detonation events overstressing the crankshaft.
