Update 17/03/17: Widow condemns CASA as 'incompetent' & 'dysfunctional' -

Next I note that NSW Deputy Coroner today handed down his findings on the tragic 2013 Dromader fire fighting accident near Ulladulla. From AAP via the Oz:

Pilot died after 'inadequate' inspection

A waterbombing pilot fighting a NSW blaze was killed after his plane's wing broke off mid-flight as a result of cracking and corrosion that was missed during an "inadequate" inspection months earlier, an inquest has found.

David Black, 43, died when his M18 Dromader aircraft crashed in an isolated and mountainous area of the Budawang National Park, in the state's south, on October 24, 2013.

The experienced pilot was preparing to attack a bushfire when the left wing of his aircraft suddenly broke off, causing the aircraft's rapid descent, Deputy State Coroner Derek Lee wrote in his inquest findings released on Monday.

Mr Black left behind his wife of 12 years, Julie, and three young children.

"David and Julie had worked together as a team, industriously, to reach a stage in life where their business was successful, their family was nurtured and cared for, and they were simply able to enjoy life," Mr Lee wrote.

"To lose David in sudden circumstances is heart-rending."

The plane Mr Black was flying was owned by his company, Rebel Ag, which provided aerial support to the NSW Rural Fire Service.

It was tested and inspected just over two months earlier by two companies, Aviation NDT and Beal Aircraft Maintenance, but Mr Lee said the work was inadequately done.

He wrote in his findings that testing by Aviation NDT used an unauthorised method and did not comply with the mandatory requirements of the Civil Aviation Safety Authority.

Further, the plane's wings were not removed during a visual inspection by Beal Aircraft Maintenance, meaning that corrosion and cracking on one of the left wing's attachment lugs was not detected.

By the time Mr Black crashed in October, the Australian Transport Safety Bureau found that cracking on the inner surface of the lug had reached a critical length of 10.4 millimetres and at least 32 secondary micro cracks were also identified.

The engineer behind the visual inspection, Donald Beal, told the inquest the manufacturer's service bulletin did not mandate removal of the wings, so he didn't see any need to remove them.

Mr Beal also said there was ambiguity about what visual inspections actually involved, Mr Lee recalled in his findings.

At the NSW Coroner's Court on Monday, Mr Lee recommended that CASA consider issuing a directive that wings be removed during inspections of M18 Dromader planes.

He also recommended they consider a different way of calculating fatigue damage, which did not just rely on flight hours but also looked at other factors that age an aircraft, such as its speed and the weight of loads that it carries.

A CASA spokesman said they would consider the recommendations carefully.

Solo mum keeps business afloat

Julie Black has been flying solo for the past 3½ years in more ways than one.

..After the accident, Ms Black had to replace the Dromaders with Air Tractors, and find a chief pilot, as well as juggling the raising of her children. “The business is still going. It is still employing people and maintaining services to our clients,” she says.

Ms Black vowed to never put pilots in Dromaders again and has since bought four Air Tractors for spraying.

“It has been extremely hard when you are used to working with someone in a partnership for 17 years, and been able to tag-team between work life and home life,’’ she says.

“When you have lost that 50 per cent and you are now 100 per cent on your own … all our decision making was done ­together.

“Now I lie in bed and night and wonder if I have made the right ­decision and what would David have thought about whatever the issue is at hand.’’

‘Incompetent’ CASA slammed

...Ms Black said the inquest by the deputy State Coroner Derek Lee showed the crash involving a Polish-built M18 Dromader was a textbook example of the Swiss cheese theory of accidents. This theory postulates that holes develop because of human error and dysfunction, and eventually they link up to cause serious accidents.

“In this accident when you go back and you look at all the holes that were lining up over a matter of 13 years, this aircraft was doomed. Had we known that we obviously would never have flown it,” Ms Black said. “When you go back through the ATSB report you can see the holes developing right back to 2000. In just about every single one of those holes CASA is involved. How CASA originally said you could use a flawed testing system (the eddy current technique) is unbelievable. It was contrary to what both the manufacturer and the FAA had mandated as the correct testing method.”

Ms Black’s solicitor, Mark Gray-Spencer of GSG Legal, said the evidence presented to the inquest clearly showed CASA failed to identify the fact that the maintenance company, Beal Aircraft Maintenance, and its non-­destructive testing company, Aviation NDT Services, was using the wrong method to test the attachments on the Dromader wings.

“Aviation NDT used an eddy current technique to test the wing attachments which was contrary to what both the manufacturer and the FAA said should be used. Both had advised that Magnetic Particle Testing had to be used,” Mr Gray-Spencer said.
“Six weeks after the approval from CASA for the eddy current technique was sent to Neil Joiner (of Aviation NDT Services), CASA issued an airworthiness directive (AD) stating that you had to use magnetic particle testing. This was inconsistent with the eddy current technique approval. The maintenance organisation should have looked at the AD and realised their procedure was not OK.”

An AD is a legislative instrument issued under federal law.

“For 13 years, from the issuing of the AD until the accident, the wrong testing was used,” he said...

And here is Pinocchio Gobson with the totally predictable zero care, zero responsibility, "we're looking into it" bollocks statement:
   
“CASA has been looking carefully at the Coroner’s report and recommendations. There are a range of issues to be considered and CASA is working through these methodically. We appreciate issues raised by the family are important.”

- That is word-weasel bureaucratese for.. "this will be O&O'd till we can quietly shuffle the report in to the infamous CASA shelf-ware out-tray"  -
