Airworthiness Directive · Amendment 39-15247 · 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 A340-541 and -642 Airplanes
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 A340-541 and -642 Airplanes
Superseded. A later AD replaced this one: AD 2012-06-25. Comply with the one in force.
This AD applies to Goodrich evacuation systems approved under Technical Standard Order (TSO) TSO-C69b, as installed on Airbus Model A330-201, -202, -203, -223, -243, -301, -321, -322, -323, -341, -342, and -343 airplanes; Model A340-211, -212, -213, -311, -312, and -313 airplanes; and Model A340-541 and -642 airplanes; certificated in any category.
The FAA is superseding an existing airworthiness directive (AD), which applies to Goodrich evacuation systems approved under TSO- C69b and installed on certain Airbus Model A330-200 and -300 series airplanes, Model A340-200 and -300 series airplanes, and Model A340-541 and -642 airplanes. That AD currently requires inspecting to determine the part number of the pressure relief valves on the affected Goodrich evacuation systems, and corrective action if necessary. For certain airplanes, this new AD requires an additional inspection to determine the part number of the pressure relief valves, and corrective action if necessary. This AD results from a report indicating that, during maintenance testing, the pressure relief valves on the affected Goodrich evacuation systems did not seal when activated, which caused the pressure in the escape slide/raft to drop below the minimum allowable raft mode pressure. We are issuing this AD to prevent loss of pressure in the escape slides/rafts after an emergency evacuation, which could result in inadequate buoyancy to support the raft's passenger capacity during ditching, and increase the chance for injury to raft passengers.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For all airplanes: Within 36 months after July 17, 2006 (the effective date of AD 2006-12-08): Perform an inspection to determine the part number of the pressure relief valve on the Goodrich evacuation systems in accordance with the Accomplishment Instructions of Goodrich Service Bulletin 25-355, dated July 25, 2005; or Goodrich Service Bulletin 25-355, Revision 1, dated July 24, 2006. After the effective date of this AD, only Goodrich Service Bulletin 25-355, Revision 1, dated July 24, 2006, may be used.
(1) If any pressure relief valve having P/N 4A3791-3 is installed, before further flight, replace the valve with a new or serviceable valve having P/N 4A3641-1 and mark the girt adjacent to the placard, in accordance with the Accomplishment Instructions of the service bulletin.
(2) If any pressure release valve having P/N 4A3641-1 is installed, before further flight, mark the girt adjacent to the placard in accordance with the Accomplishment Instructions of the service bulletin.
As of July 17, 2006, no person may install a pressure relief valve having P/N 4A3791-3, on any airplane equipped with Goodrich evacuation systems identified in Goodrich Service Bulletin 25-355, dated July 25, 2005.
For Model A340-541 airplanes: Within 36 months after the effective date of this AD, perform an inspection to determine the part number of the pressure relief valve on the Goodrich evacuation systems in accordance with the Accomplishment Instructions of Goodrich Service Bulletin 25-355, Revision 1, dated July 24, 2006.
(1) If any pressure relief valve having P/N 4A3791-6 is installed, before further flight, replace the valve with a new or serviceable valve having P/N 4A3641-26 and mark the girt adjacent to the placard, in accordance with the Accomplishment Instructions of the service bulletin.
(2) If any pressure release valve having P/N 4A3641-26 is installed, before further flight, mark the girt adjacent to the placard in accordance with the Accomplishment Instructions of the service bulletin.
(i) As of the effective date of this AD, no person may install a pressure relief valve having P/N 4A3791-3, on any airplane equipped with Goodrich evacuation systems identified in Goodrich Service Bulletin 25-355, Revision 1, dated July 24, 2006.
(j) As of the effective date of this AD, no person may install a pressure relief valve having P/N 4A3791-6, on any airplane equipped with Goodrich evacuation systems identified in Goodrich Service Bulletin 25-355, Revision 1, dated July 24, 2006.
