Aviation safety issues and actions
Recommendation issued to: Civil Aviation Safety Authority
|Date issued:||12 June 1998|
|Safety action status:|
The Bureau of Air Safety Investigation recommends that airline
Review their standard operating procedures (SOP) and airline policy to require only one crew member to make control inputs at any one time unless stated to the contrary in an emergency/abnormal procedure, and to emphasise the consequences of multiple simultaneous flight control inputs.
|Date issued:||27 November 1997|
|Response from:||Civil Aviation Safety Authority|
|Action status:||Closed - Accepted|
CASA has reviewed the Operational Standard "Simultaneous Opposite Direction Operations" as you have recommended.
Following Occurrence 9700052 on 5 January 1997 the instructions in AIP OPS paragraph 19.4 were changed by NOTAM to require pilots to remain on Tower frequency until instructed to change, thus enabling Tower to correct the kind of confusion evident during the occurrence. The amendment will be correctly inserted into the AIP OPS text by AIP Amendment List 20, effective 4 December 1997.
Given the change to procedures our conclusion is that the standard expressed in the CASA Manual of Operational Standards (MOS) Part 3 Chapter 5.9 is adequate.
The MOS standard will be further reviewed in the light of any study which may be undertaken by Airservices in response to your recommendation R970150.
After dispatching a copy of the [name supplied] report to CASA the following response was received on 28 Aug 1998:
The letter requests a formal CASA response to the recommendations in a report attributed to [name supplied]. It cites the CASA/BASI MOU as the basis for advice of actions CASA intends to take in response to those recommendations.
It is our belief that this request is not consistent with the MOU between our two organisations. That MOU lays out a basis for CASA to respond to safety deficiencies identified by BASI and recommendations made by BASI to rectify those deficiencies. It does not require CASA to address recommendations made by a third party.
It was our understanding that BASI would be forwarding a draft investigation report to CASA for comment. That report would be along the lines of the outline we had informally discussed early in July, and would at your discretion incorporate such findings of the Gleave report as you saw fit. We would of course be pleased to provide comment on such a report and indicate actions taken or planned to address any recommendations the Bureau may choose to make. We are, as you know, already addressing a number of the issues discussed at our meeting in July. If you have any questions on this issue please don't hesitate to call.
