Airworthiness Directive · Amendment 39-17174 · Fire protection
BAE SYSTEMS (Operations) Limited Airplanes
This AD applies to BAE SYSTEMS (Operations) Limited Model 4101 airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all BAE SYSTEMS (Operations) Limited Model 4101 airplanes. This AD was prompted by reports that the fire extinguisher in the toilet vanity unit needs to be mounted vertically rather than horizontally. This AD requires inspecting to determine if a certain fire extinguisher bottle is installed, and repositioning the affected fire extinguisher bottle to the vertical position. We are issuing this AD to detect and correct the orientation of the fire extinguisher bottle in the toilet vanity unit to the vertical position, which if not corrected, could result in a toilet waste bin fire spreading, and consequent damage to the airplane and injury to its occupants.
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 2 months after the effective date of this AD, determine from the table specified in paragraph 2.A.(1) of BAE SYSTEMS (Operations) Limited Service Bulletin J41-26-008, Revision 2, dated September 20, 2011, if fire extinguisher bottle part number (P/N) BA20509AM-4 is fitted to the airplane. If a fire extinguisher bottle P/N BA20509AM-4 is fitted, before further flight, reposition the fire extinguisher bottle, in accordance with the Accomplishment Instructions of BAE SYSTEMS (Operations) Limited Service Bulletin J41-26-008, Revision 2, dated September 20, 2011.
