Airworthiness Directives; Cessna Aircraft Company 172 and 182 Series Airplanes

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company 172 series airplanes with the BRS-172 Parachute System installed via Supplemental Type Certificate (STC) No. SA01679CH and Cessna Aircraft Company 182 series airplanes that are equipped with the BRS-182 Parachute System installed via STC No. SA01999CH. This AD requires you to replace the pick-up collar support and nylon screws for the BRS-172 and BRS-182 Parachute System. This 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 issuing this AD to prevent premature separation of the collar, which could result in the parachute failing to successfully deploy.
