The Thinback Emergency System was developed by Parachutes Australia and has been designed with the comfort and utility of the pilot in mind. The container is lightweight, thin and comfortable with an adjustable padded harness.


The Thinback Parachute Assembly has been tested to the requirements of Civil Aviation Safety Authority C.A.S.R. Part 21 sub part 0, Emergency Parachutes. United States Federal Aviation Administration Technical Standard Order T.S.O - C23b was used as the specification.

Parachutes Australia holds both Certificates of Type Approval (CTA) issued by the Civil Aviation Safety Authority C.A.S.R. and letters of TSO Authorisation from the United States FAA for the various component parts that make up the Thinback Parachute Assembly.

The Thinback Parachute Assembly will meet the requirements for a 'Standard' category parachute provided the canopy fitted to the Thinback pack and harness has been certified to the standard type category. 

Where a 'Low speed type' category parachute canopy is fitted to the Thinback or Thinback pack and harness assembly, the resulting assembly must be identified as a Low Speed Parachute and is limited to use in airplanes under 150mph.
