| 2011-33359 | Airworthiness Directives; Goodrich Evacuation Systems Approved Under Technical Standard Order (TSO) TSO-C69b and Installed on Airbus Airplanes | Proposed Rule | We are revising an earlier proposed airworthiness directive (AD) for Goodrich Evacuation Systems approved under Technical Standard Order (TSO) TSO-C69b and installed on Airbus Model A330-200 and -300 series airplanes, Model A340-200 and -300 series airplanes, and Model A340-500 and -600 series airplanes. That NPRM proposed to supersede an existing AD. That NPRM proposed inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems, replacing certain pressure relief valves, and adding airplanes to the applicability. That NPRM was prompted by reports that during workshop testing, certain pressure relief valves, which were required by the existing AD, did not seal and allowed the pressure in certain slides/rafts to fall below the minimum raft mode pressure for the unit. This action revises that NPRM by adding certain airplanes to the applicability. We are proposing this supplemental NPRM to correct the unsafe condition on these products. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes. | 2011-12-29 | 2011 | 12 | https://www.federalregister.gov/documents/2011/12/29/2011-33359/airworthiness-directives-goodrich-evacuation-systems-approved-under-technical-standard-order-tso | https://www.govinfo.gov/content/pkg/FR-2011-12-29/pdf/2011-33359.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are revising an earlier proposed airworthiness directive (AD) for Goodrich Evacuation Systems approved under Technical Standard Order (TSO) TSO-C69b and installed on Airbus Model A330-200 and -300 series airplanes, Model A340-200 and -300 series... |
