View Full Version : CASA proposal on jabiru engined aircraft

13th November 2014, 09:57
FYI the Australian regulator (CASA) has today commenced a regulatory process that may lead to restrictions on all Jabiru engined aircraft in the country.

Here is the CASA summary of the proposal: http://www.casa.gov.au/wcmswr/_assets/main/newrules/download/spc-cd1425ss.pdf
and a draft of the proposed Instrument: http://www.casa.gov.au/wcmswr/_assets/main/newrules/download/consult-draft-cd1425ss.pdf

I read elsewhere that this proposal has been (temporarily?) withdrawn pending discussions between Jabiru and CASA.
Shouldn't affect us microlighters because we always expect our engines to stop without notice, don't we? Every flight which reaches its planned destination is a bonus.

From Jabiru Forum.
This is the latest CASA missive apparently to the Aussie 'LAA' I think.

Response from email to CASA re consultation Thu Nov 20, 2014 1:18 pm (PST) . Posted by: stuartmspencer "Dear Mr Spencer

Thank you for your email responding to the invitation for comments on operational limitations being proposed by the Civil Aviation Safety Authority (CASA) for aircraft fitted with Jabiru engines.

The proposed measures are precautionary and intended to reduce the potential risk of harm or injury resulting from possible Jabiru engine occurrences, until the causes of these occurrences have been identified and addressed. CASA has circulated the consultation draft to provide operators and other interested persons with notice of the actions CASA is proposing to take, noting that no action has been taken yet, as well as an opportunity to comment on those proposals, and offer any suggested alternatives.

CASA has been looking at data and reports about Jabiru piston-engine failures for some time. In the course of that review, problems related to Jabiru engines that have stood out range from full and partial power loss and in-flight engine shutdowns, to rough running and oil leaks. CASA has identified more than 40 Jabiru engine problems and events that have occurred in 2014 alone.

Mechanical problems that have been identified by Jabiru include through bolt, valve and cylinder, and fly-wheel bolt failures. The contribution of particular kinds of operations (for example, student training) and maintenance-related factors to some of these failures has yet to be determined.

Jabiru, as the manufacturer of these engines, has certain obligations under the relevant International Standards, and civil aviation safety legislation in terms of the identification and rectification of such engine problems irrespective of when they occurred or what may have caused them, and CASA is working with Jabiru to arrive at a solution.

CASA will consider all comments received on the consultation draft and the discussions held with Jabiru (which are ongoing) before making a final decision on any operating limitations that may need to be imposed, as a precautionary measure in the interests of safety.

In the expectation we will receive constructive and informative input, CASA has extended the consultation period by an additional 7 days to 27 November 2014. At the conclusion of that period, CASA will assess the information we have received, in conjunction with other information available to us, and act in accordance with our obligations under the Civil Aviation Act.

Your input will be considered in the process of determining the nature and scope of such operating limitations as CASA may ultimately decide need to be imposed in the interests of safety.

CASA fully appreciates that the imposition of any operational limitations will affect Jabiru and the many owners and operators of aircraft fitted with Jabiru engines. As an Australian-manufactured engine, CASA has special obligations in relation to Jabiru. CASA’s intention is to help ensure that safety-related problems associated with Jabiru engines—mechanical, operational or maintenance-related—are identified and addressed as quickly and effectively as possible.

Yours sincerely

Steve Neal
Office of the Director of Aviation Safety"
