| This Airworthiness Directive becomes effective on 22 December 2005. |
| Background: | This Directive requires the revision of the AFM to advise the flight crew to don oxygen masks as a first and immediate step when the cabin altitude warning horn sounds. This action is necessary to prevent incapacitation of the flight crew due to lack of oxygen, which could result in loss of control of the aeroplane. |
