Applicability
The Airworthiness Directive applies to a wide range of Cessna 172 models, including the 172A through 172S, as well as the Cessna 170 and R172 series. This broad applicability indicates that the directive is relevant for many aircraft in the Cessna 172 family.
Requirement
The directive requires the removal and replacement of the pick-up collar support and two retaining screws associated with the BRS-172 Parachute System. This action must be performed in accordance with the specified service bulletin from Ballistic Recovery Systems Inc.
Compliance
Operators are required to complete the necessary actions within 25 hours of time in service after the effective date of the directive, which is 13 March 2008. This compliance timeline is critical for ensuring the safety of the aircraft.
Background
The directive was issued following notifications from the FAA regarding potential issues with the pick-up collar assembly of the parachute system. There is a risk that the collar may prematurely detach from the launch tube, which could lead to failure in parachute deployment.
Safety notes
- Premature separation of the collar could result in parachute failure during deployment.
