Airworthiness Directive · Amendment 39-17232 · Hydraulic power
BAE SYSTEMS (OPERATIONS) LIMITED Airplanes
This AD applies to BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146-100A, -200A, and -300A airplanes, and Model Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in any category; except for airplanes operating in a cargo or non-passenger configuration. The requirements of this AD become applicable at the time an airplane operating in a cargo or non-passenger configuration is converted to a passenger configuration.
We are adopting a new airworthiness directive (AD) for certain BAE SYSTEMS (OPERATIONS) LIMITED Model BAe 146 series airplanes and Model Avro 146-RJ series airplanes. This AD was prompted by hydraulic pipe ruptures in the center of the cabin resulting in passengers being contaminated with hydraulic fluid. This AD requires installing a hydraulic fluid containment system. We are issuing this AD to prevent harmful or hazardous concentrations of hydraulic fluid or hydraulic vapor from entering the passenger compartment, possibly resulting in injury to the 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.
Within 4,000 flight hours or 24 months after the effective date of this AD, whichever occurs first, install the hydraulic fluid containment system, in accordance with the Accomplishment Instructions of BAE SYSTEMS (OPERATIONS) LIMITED Modification Service Bulletin SB.29-048-30676A, Revision 2, dated December 23, 2010.
