hours provided the source of the contamination is identified and isolated from the cabin environment before further flight, using either flight operations procedures or maintenance procedures.
 COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

             2.    Initially at the next A Check after the effective date of this Airworthiness Directive, and thereafter repeat the inspection at intervals not to exceed 500 flights.

             3.    As of the effective date of this Airworthiness Directive.

            4.    Unless previously accomplished, no later than 3 May 2001. This Airworthiness Directive becomes effective on 3 April 2001.
            Background:  Cabin air quality has been the subject of intense investigation for a number of years. As a result, local BAe 146 operators have incorporated various modifications to the cabin air system, APU and engines. They have also introduced improved maintenance practices to further address this issue. These actions have resulted in a significant reduction in the number of cabin contamination incidents reported to CASA and the ATSB. In addition, the operators have changed the oil used in their respective fleets to Mobil 291; a fourth generation turbine oil.

            The CAA (UK) has advised a recent crew incapacitation incident in the UK may have been associated with contamination of the cabin air system with engine oil. While overseas operators have experienced cabin air contamination events, these events have not generally been treated with the same degree of concern, as is the case with Australian operators. Consequently, overseas operators have not been as active in introducing the cabin air quality improvements into their aircraft.

            This AD reflects action by the CAA (UK) and effectively mandates action already enacted by local operators to address cabin air contamination events. It also serves to satisfy the recommendation by the Senate Rural and Regional Affairs and Transport References Committee for improved reporting of cabin air contamination events in Australia.
