CASA demonstrate siege mentality

In the last few weeks, since the publication of the Jabiru article in the Australian on 29th July 2016, #casa are attempting to “…pervert a reasonable safety case…” by their actions. In the case of Jabiru, Jonathon Aleck refuses to allow the removal of restrictions on Jabiru to go, saying:

“Our concerns were real and demonstrable and not the result of an exclusively CASA assessment, with the Air Traffic Safety Bureau corroborating as well,” Dr Aleck said.


This is despite the following repeal of the Jabiru Instrument:

CASA 102/15 Directions/Civil Aviation as made
This instrument prescribes operating limitations on aircraft fitted with engines manufactured by, or under licence from or under a contract with, Jabiru Aircraft Pty Ltd (Jabiru-powered aircraft), to manage risks arising from a high incidence of engine loss-of-power events and other reliability issues. The instrument is, therefore, an urgent safety measure designed to mitigate immediate risks to persons flying in Jabiru-powered aircraft.
Administered by: Infrastructure and Regional Development
Made 29 Jun 2015
Registered 29 Jun 2015
Tabled HR 10 Aug 2015
Tabled Senate 10 Aug 2015
Date of repeal 30 Jun 2016
Repealed by Self Repealing

This is a direct example where Aleck of #casa does not wish to meet the umpires judgement.


A further case today is reported by The Australian, in Tasmanian airspace, where #casa will not properly deal with a known safety case on use of radar, made known by Dick Smith.

No-change ruling ‘courts tragedy’ at Hobart airport

Australia’s air safety regulator has decided against any serious change to Hobart’s air space, prompting claims it is courting tragedy and continuing a cover-up over Tasmania’s $6 million radar system.

The Civil Aviation Safety Authority yesterday released the findings of a review of Hobart’s airspace, ordered after stories in The Australian about failures in the state’s radar system, known as TASWAM. The Australian last year revealed TASWAM was not being used to control aircraft to the ground but only as an extra tool for tower controllers providing “procedural separation”, which relies on visual observation and communication with pilots.

CASA responded to criticism, and a projected 30 per cent to 40 per cent increase in passengers over the next five years, by ordering an Office of Airspace Regulation review of Hobart airspace.

The report released yesterday rejects calls by pilots and Airlines of Tasmania for TASWAM to be used as they believed it was intended: to guide aircraft to the runway, rather than to 8500 feet as occurs now. Instead, it recommends continuing with local air tower controllers using procedural sep­aration below 8500 feet, calling this “appropriate”.

Aviator Dick Smith last night said it seemed CASA was continuing a “cover-up” of TASWAM and would not act until there was a death.

Then there is #Pelair, #Mildura, Lockhart River, #ATR, ruled over variably by Skidmore, McCormick and Aleck.
