Safety Recommendation

The Australian Transport Safety Bureau recommends that the Civil Aviation Safety Authority, in conjunction with the relevant industry associations, assess the desirability of a requirement for Helicopter Underwater Escape Training for specialist aerial work operations, such as water-bombing in support of fire fighting operations.

The following response was received from the Civil Aviation Safety Authority on 6 February 2004:

Aviation Safety Standards has reviewed this recommendation and proposes to test the desirability of Helicopter Underwater Escape Training (HUET) with industry through the issue of a Discussion Paper or similar consultative arrangement. CASA expects that this issue will be canvassed when the post implementation review of Civil Aviation Safety Regulation (CASR) Part 133 occurs.

Response text:

Helicopter Underwater Escape Training (HUET) was reviewed as part of the CASR Part 133 Discussion Paper DP00060S, however this was in a general sense only, with specific references being attached to over-water operations more than 10nm from land and for Marine Pilot Transfer (MPT) operations.


The following section from the discussion paper refers:

Comment 93 - DP Ref 133.825 - Life Jackets

There were five responses to paragraph 133.825. Two disagreed with the donning requirements, two questioned the use of lifejackets in amphibious operations and one made reference to CAO 20.11 requirements.

CASA response

The proposed rule generally duplicates the requirements of Part 91, however, CASA believes that there is merit in emphasising when flotation equipment must be carried. Accordingly, the proposed rule has been amended to that effect. A requirement for underwater escape training has been inserted for crew members engaged in regular overwater operations.


Paragraph 133.825 has been amended.

Therefore with respect to this particular recommendation CASA has consulted as outlined except that consultation was within the general terms outlined in the draft CASR Part 133 and not specifically in regard to Aerial Fire Fighting operations.

Aerial Fire Fighting Operations which are outlined in CASR Part 133 T.7 require the operator's operations manual to include a supplement that deals with fire fighting operations and do not specifically address the content of that supplement or the need for HUET.

It is envisaged that as part of the process of assessing the Operations Manual supplement that deals with fire fighting operations, and within the priorities of its ongoing surveillance program, CASA will be reviewing the standard operating procedures of operators who conduct such operations with the view of assessing how effectively they are addressing the risks associated with this issue.
