Tyre Sampson, 14, slipped out of his seat about halfway down the ride that drops riders nearly 120 metres at speeds over 120km/h.

A 14-year-old boy who fell to his death at a US amusement park earlier this year exceeded the ride’s weight limit by nearly 45kg, according to an autopsy report obtained by CNN.

Tyre Sampson died on March 24 while visiting ICON Park outside Orlando with family friends.

He was a passenger on the Orlando FreeFall drop tower ride, which operators describe as the world’s tallest freestanding drop tower.

It sends passengers up and then drops them nearly 120 metres at speeds reaching more than 120km/h, according to the park.

Sampson slipped out of his seat about halfway down the Free Fall ride located in a tourist area of Orlando, according to NBC News.

The owner’s manual for the tower lists the ride’s weight limit at 130kg.

Sampson was just over six feet tall and weighed 173kg, the autopsy report said.

The autopsy also ruled Sampson’s cause of death was blunt force trauma, resulting in multiple fractures, lacerations and haemorrhaging to his head, neck and extremities.

His manner of death was an accident, the report said.

In April, a forensic engineering firm - Quest Engineering & Failure Analysis Inc - was hired by state officials to investigate Sampson’s death.

It found that manual adjustments had been made to two seats on the drop tower ride, including the seat occupied by Sampson.

This adjustment allowed for a greater gap than normal between the harness and the seat, the report by the firm said.

“The cause of the subject accident was that Tyre Sampson was not properly secured in the seat primarily due to mis-adjustment of the harness proximity sensor,” the forensic engineering firm’s report said.

The Orlando Freefall ride has been closed since Sampson’s death and will remain so indefinitely.

An attorney for the ride’s operator, Orlando Slingshot, issued a statement on Monday saying Tyre’s death “was a tragic accident”.

“We continue to communicate and cooperate with representatives of Tyre’s family, as well as the Department of Agriculture,” said Slingshot attorney Trevor Arnold.

“We are devoted to working with our lawmakers in making lasting safety changes in the amusement park industry.”

In a previous statement, Arnold said “all protocols, procedures and safety measures provided to us by the manufacturer of the ride were followed”.

Sampson’s parents - Nekia Dodd and Yarnell Sampson - are being represented by different attorneys but filed a wrongful death lawsuit together.

The suit names multiple defendants including ICON Park, Orlando SlingShot, the ride’s manufacturer, Austria-based Funtime Handels; and the manufacturer of the seats and harnesses, Germany-based Gerstlauer Amusement Rides.

The lawsuit said the defendants failed to warn Sampson about the risks of someone of his size going on the ride and that they did not provide an appropriate restraint system.
