Summary
We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 172 and 182 series airplanes that are equipped with the BRS-172 and BRS-182 Parachute System. This proposed AD would require the replacement of the pick-up collar support and nylon screws for the BRS-172 and BRS-182 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.
