Narrative:

While flying the Fern5 arrival into smo; descending thru FL370; we experienced severe wake turbulence from another aircraft in front of us. Believe [the aircraft] to be an A380; on the SADDE6 arrival to lax. The event took place between rebrg and derbb intersection with ATC reporting the A380 'super' was 15 NM ahead of us and descending. The aircraft upset was an abrupt negative g's; followed immediately by a right roll to 90+ degrees. Then; quickly brought the plane back to a level attitude; assessed passenger injuries; aircraft control in approach/landing configurations; and if any structural damage. No serious injuries; and aircraft integrity was verified. Continued to destination due to close proximity of all diverts (vny; bur; lax). We [advised ATC of a medical issue with a passenger]; as a precaution; to have passenger checked out by medical personnel upon arrival. They were examined and released to go home within 10 mins.the Fern5 and SADDE6 converge and share fixes at derbb; reyes and fim. No altitude restrictions on either arrival. The Fern5 is tailored for smaller GA aircraft and SADDE6 tends to be larger commercial aircraft. These two arrivals should not converge; share fixes; and [they should] have altitude crossing restrictions. ATC should also be aware of these conflicts and not allow 'heavies [and] supers' to be descending thru this airspace [without] much; much greater lateral and vertical separation.

Title: C560XL flight crew reported an upset when they encountered 'severe' wake turbulence from a preceding A380 on arrival into the LAX basin.

Narrative: While flying the Fern5 arrival into SMO; descending thru FL370; we experienced severe wake turbulence from another aircraft in front of us. Believe [the aircraft] to be an A380; on the SADDE6 arrival to LAX. The event took place between REBRG and DERBB intersection with ATC reporting the A380 'super' was 15 NM ahead of us and descending. The aircraft upset was an abrupt negative g's; followed immediately by a right roll to 90+ degrees. Then; quickly brought the plane back to a level attitude; assessed PAX injuries; aircraft control in approach/landing configurations; and if any structural damage. No serious injuries; and aircraft integrity was verified. Continued to destination due to close proximity of all diverts (VNY; BUR; LAX). We [advised ATC of a medical issue with a passenger]; as a precaution; to have PAX checked out by medical personnel upon arrival. They were examined and released to go home within 10 MINS.The Fern5 and SADDE6 converge and share fixes at DERBB; REYES and FIM. No altitude restrictions on either arrival. The Fern5 is tailored for smaller GA aircraft and SADDE6 tends to be larger commercial aircraft. These two arrivals should not converge; share fixes; and [they should] have altitude crossing restrictions.
