Main Lift Web Safety Notice

Published by PLI on

Subject: Re-designation of use.

Models Affected: All models of SST/Racers, Racer Elites & Racer Trainers
equipped with a single strand adjustable main lift web.

Background: The above listed equipment has not been manufactured for over 8 years. It was superceded with a double strand pulley system for adjustment of the main lift web.

Recent developments and increased understanding with the deployment anomalies generated by malfunctioning Ram-Air parachutes indicate that the left/right distribution of loads may exceed the strength capacity of the original design. These anomalies could cause failure of the main lift web.

This has not happened on Jump Shack equipment but we believe that theoretically it could happen and that all single strand adjustable Main lift webs are vulnerable.

Action: The above identified equipment must be re-designated as and use
restricted to ROUND PARACHUTES ONLY. This is mandatory.

Compliance Date: Immediately.
