Eight-Year-Old Boy Was Fatally Injured When A Plane Went Down In June Of Last Year.

A sightseeing flight in the California desert last June has now become the basis for a wrongful death lawsuit filed by the mother of the eight-year-old boy fatally injured in a accident.

The boy was Sebastian Grewal. He was flying with a commercial pilot who was his mother's boyfriend aboard an American Aviation AA-1A when the accident occurred. Grewal and the pilot were both fatally injured when the plane went down during a "low pass" that was requested by the onlookers, according to the NTSB's preliminary report on the accident.

Now, Frida Cagabhion has named the boy's father, Jashandeep "Josh" Grewal, as a "nominal defendant" in her wrongful death suit, despite the elder Grewal's assertion that he was not present at the accident scene. He shared joint custody with Cagabhion, and says his son was with his mother at the time.

The suit, filed in Los Angeles Superior Court, also names American Aviation, the manufacturer of the plane, as well as co-owners Brian Michael Lee and Jeffrey Moir. According to the suit, Lee and Moir are "liable for the negligent piloting and/or operation of the airplane." Lee was piloting the plane when it went down.

According to court documents, the suit claims that "...the airplane was not in a condition for safe operation when Lee operated it on June 9, 2014, and it suffered from a mechanical malfunction and/or power loss resulting in the crash of the airplane and the death of Lee and (Sebastian)."

It says that Moir had a "duty to use ordinary and reasonable care in installing, maintaining and inspecting the airplane." The manufacturer is liable, according to the suit, because the company " knew or should have known, that (the) airplane, and/or its component parts, was unsafe for their ... uses." Cagabhion claims that there were manufacturing and design defects with the AA-1A.

The boy's father filed a wrongful death suit in May in connection with the accident, according to the paper. He named Lee, the LA Fire Department, Moir, and the City of Los Angeles. Grewal said that there was video of the accident, but the the LAFD had it destroyed.

The accident is still under investigation by the NTSB.
