Summary
We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company 150 series airplanes with the BRS-150 Parachute System installed via Supplemental Type Certificate (STC) SA64CH. This proposed AD would require the replacement of the pick-up collar support and nylon screws for the BRS-150 Parachute System. This proposed AD results from notification by Ballistic Recovery Systems, Inc. (BRS) that the pick-up collar assembly may prematurely move off the launch tube and adversely affect rocket trajectory during deployment. We are proposing this AD to prevent premature separation of the collar. This condition could result in the parachute failing to successfully deploy.
