The Bureau of Air Safety Investigation recommends that the Civil
Aviation Safety Authority, in conjunction with the aircraft
manufacturer, British Aerospace Plc, address deficiencies that
permit the entry of fumes into the cockpit and cabin areas of
BAe146 aircraft. These deficiencies should be examined by the
regulatory authority as part of its' responsibilities for initial
certification and continued airworthiness of the BAe 146
Aircraft.



As a result of the investigation into this occurrence, the Bureau
simultaneously issues recommendation R990053 to British Aerospace
Plc:





"The Bureau of Air Safety Investigation recommends that British
Aerospace Plc liaise with the engine manufacturer, AlliedSignal, to
investigate failures within the engine that result in fumes
entering the cockpit and cabin areas of BAe146 aircraft".

Response Text

In the lengthy period between the incident and the release of
your report,CASA has investigated this issue in considerable
detail, in conjunction with the aircraft manufacturer and the major
Australian operators. As a result of this work, and discussions
with the certifying authority (the UK Civil Aviation Authority),
CASA is satisfied that the BAel46 aircraft in service in Australia
are safe for public transport. CASA technical specialists are
available to brief your investigators on the scope and findings of
this work.



As your recommendation does not specify the nature of any
additional deficiencies that the Bureau believes need to be
addressed by CASA and the aircraft manufacturers, I am seeking
details of any deficiencies that you believe have not been
appropriately dealt with. It would also assist us in providing a
meaningful and constructive response to your recommendations if you
were to provide us with details of any incidents that have occurred
since the original incident in 1997.



In the meantime, we will continue to monitor the situation and
review any information that comes to hand.

ATSB Response

The following letter was sent to the Civil Aviation Safety
Authority on 24 January 2000:



Thank you for your response to Occurrence Brief 199702276 and
Recommendation R19990052 dated 5 November 1999.



In regard to the detailed investigation CASA has carried out in
conjunction with the manufacturer and UK CAA, your conclusion that
the BAe 146 aircraft type is safe for public transport in Australia
has been noted.



This has been a very complex issue and to ensure that the ATSB is
fully conversant with the reasons behind your conclusions, I would
be most pleased to accept your offer of a CASA technical specialist
briefing of our investigators. To facilitate planning, your early
advice as to when this could take place is sought

 

ATSB Note:

In early May 2000, Bureau staff met twice with CASA staff to
discuss fumes occurrences and actions available to mitigate fumes
events. The actions available included modifications for BAe 146
aircraft and one operator had commenced modifying its 146
fleet.

The ATSB reclassifies the recommendation as Closed - Partially
Accepted.
