Update published 1 August 2022

A third draft of this report will be released to Directly Involved Parties for comment in August 2022. The ATSB undertook a significant review of the available material and sourced additional evidence from organisations in Australia and overseas following the circulation of a draft of the report to Directly Involved Parties in 2019.

Additional work was considered necessary when changes were made to the design of surfaces at Essendon Fields Airport that manage the location and height of buildings in proximity to runway 08/26. These changes were made by the aerodrome operator around the time the draft report was released for consultation. P2 - WTF..   The changes were advised in update 1

The investigation has involved consideration of historically complex subject matter with the application of both Australian and international aerodrome design requirements dating back to the 1970s. The ATSB has applied considerable effort to understanding the application and function of those aerodrome design requirements from the 1970s to the present in the context of changes at Essendon Fields Airport. It has taken the investigation time to overcome the challenges of limited information available from historical periods to provide context to the investigation.

A final report is expected to be released publicly in the last quarter of 2022

 
From update 1 (nearly 2 years ago): 

The Major Development Plan (MDP) for the Bulla Road Precinct retail centre development was approved by the Minister for Transport and Regional Development in 2004. Building of the precinct was completed in 2005. The MDP located the lower boundary of the transitional surface 90 m from the centreline of runway 08/26 (see Figure 1). That distance was founded on two criteria:

• a runway strip width of 180 m (90 m either side of the runway centreline)
  
• the location of the lower boundary of the transitional surface immediately adjacent to the runway being determined by the runway strip dimensions.
  

Using these criteria, the MDP placed the buildings immediately adjacent to and just below the transitional surface associated with runway 08/26. Had they intruded into the transitional surface, an approval would have been required under Part 12 of the Airports Act 1996, and the Civil Aviation Safety Authority (CASA) would have considered the development as being obstacles requiring determination under the relevant safety regulations...

...In November 2015, CASA promulgated CASA instrument 153/15, which was issued to the airport operator. This instrument required the operator to publish the overall strip width for runway 08/26 as 300 m. The basis of this requirement was that there was no record on how the 180 m runway 08/26 strip width had originated, nor were there records as to the previous standard under which that measurement was authorised. The 180 m runway strip width was not authorised under the 2015 version of the standards, which required a 300 m strip width (150 m either side of the runway centreline)...

Why is the ATSB concerned with the actions of the airport operator, the department and CASA (CASA instrument 153/15) post the Minister approved 2004 MDP (which included the approval for the DFO development)? -
