| This Amendment becomes effective on 27 August 2009. | |
| Background: | A quality control inspection performed during completion of one Falcon 900EX aeroplane has shown that the crew and passenger Right-Hand (RH) oxygen lines may both interfere with the frame 8 of the aeroplane structure. A subsequent design review of the oxygen lines routing has confirmed that, on certain aeroplanes, equipped with a 115 cu-ft oxygen cylinder in the RH mid-cabin, may have been installed in such a way as to cause interference with the structure. This condition, if not corrected, could lead to an oxygen leak.As a result, the original issue of this Directive required inspection of the oxygen lines, replacement of any damaged lines and modification of their support assembly. |
| This Amendment, whilst continuing the requirements of the original issue, requires compliance in accordance with revision 1 of the service bulletin and revises the applicability. | |
| The original issue of this Directive became effective on 30 July 2009. |
