This is the story of my (Carl Holden's) flight and crash in a Jabiru Aircraft from Wedderburn in 2001. The aircraft was claimed to be "fully GA certified" and had "just come off the GA register. Ron Bertram was the Pilot and claimed to be the Maintainer. Bertram claimed he was a LAME (Licensed Aircraft Mechanical Engineer) * see below. The wreckage was taken to the Jabiru factory "very shortly" after the crash - without my knowledge. The engine strip-down inspection was performed at the Jabiru factory. To date - over 7 years later, despite many requests, the report of the engine strip-down has never been released to me by Jabiru or any other party. And I am still waiting. Why ? Can anyone shed any light on what caused this engine to fail ? * Bertram died in 2006, test-flying a Lancair he had just repaired (engine failure on climb-out). By 2007, following years of obstruction, I was able to gain access to his CASA licensing records - and there is no record of him having any maintenance qualifications. Read the ATSB report here - VH-ZNZ Lancair crash (pdf) If anyone has any information to substantiate Bertram's claims he was a C-130 Pilot in the 'first' Gulf War, or a 'Caribou Pilot', please let us know. Bertram was at the time of his crash, the President of AOPA Australia. UPDATES December 2008 Bogus Qantas engineer sent to jail Three times in 2006 I asked CASA CEO Bruce Byron a series of safety related questions, in writing, relating to the 2001 crash and the 2006 crash - and he has refused to answer since. Why ? latest: Bruce Byron to step down as CASA CEO AOPA's preferred insurer in the 1990's was Booker International. AOPA have refused repeated requests for assistance with this matter. Why ? Jabiru Aircraft has consistently refused to supply any information on the cause of the Engine failure, despite repeated written requests. Why ? CAMIT (the engine builder) has refused to supply any information on the cause of the Engine failure, despite written requests. Why ? JABIRU ENGINE USER REPORTS CAA (Civil Aviation Authority) South Africa report/expert opinion - July 2004 (pdf) (I wish I had been informed of this prior to the flight ! - Carl Holden) "Jabiru engine cylinders with engine serial numbers up to 644, have smaller cooling fins which causes the cylinders to overheat and the engines to fail. Engines with serial numbers from 645 upwards are fitted with re-designed cylinders with larger cooling fins which results in improved cooling" Where's the AD, AN, Service Bulletin, Defect Notice or any relevant documentation from the Manufacturer or CASA, as it is a CASA certified engine for "VH" aircraft use. Why ? Van's forum pages - Support problem for Jabiru engines 1 Van's forum pages - Support problem for Jabiru engines 2 Jabiru crash, engine failure, Azores MrSoaring - News - July 2002 (link) Note comments "....Unfortunately Jabiru have had a bit of a bad name causedby some of the earlier engines with the small heads and no oil cooler. Therehas been very little trouble with J2200 sr no 710 and up as this engine has thelarge heads, oil cooler and larger diameter Bing carburettor." EAA Sport Pilot article by Dave Jalanti - Flying behind a Jabiru engine - July 2005 (pdf) Note comments Page 57 - "Unfortunately, the cylinder head temperatures went slightly higher than 385°F, high enough to warp the two rear cylinder heads. After this flight, I learned from Jabiru USA that overheating cylinder heads had become enough of an issue that Jabiru had redesigned the heads, adding more and larger cooling fins, and had changed the shape of the combustion chamber. It also redesigned the cooling ducts to improve the airflow, particularly over the rear cylinders." (In the USA is it not a requirement for Manufacturers/Importers to inform Pilots of "Known Defects" ?) Dave Jalanti's engine number is quoted as "478" UK AAIB (Aircraft Accident Investigation Board) report on G-TUBB Engine Failure - 10/2002 (pdf) Summary - "The engine suffered a catastrophic failure due to the number three cylinder exhaust valve becoming stuck open in the valve guide. The piston then struck the valve, causing the valve head to detach. This lead to the destruction of the piston and bending of the connecting rod. Following the piston break up the engine seized. The exhaust valve became jammed due to excess carbon build up as a result of overheating of the number three cylinder." (In the UK is it not a requirement for Manufacturers/Importers to inform Pilots of "Known Defects" ?) JABIRU ENGINE PISTON and CYLINDER HEAD FAILURES MASQUITO (Belgium) Helicopter development Progress Report. November 2001 - July 2002. More engine problems..... "... Jabiru engine suddenly stopped without warning during one of the ground test runs. When we tried to start the engine again, the starter was not capable of turning over the engine. Further inspection showed that the engine crankshaft could not be rotated." " If the crankshaft wouldn't turn, then it was indicative that something serious had gone wrong. When the engine was dismantled, we found one of the pistons had broken into several pieces, and the crankshaft and all its' supporting bearings had worn very badly. A full report with accompanying pictures was sent to the UK CAA and to the Australian manufacturer Jabiru." "The most likely explanation (according to Jabiru) was that our piston shattered because the gudgeon pin (the round tube joining the conrod to the piston) was no longer held in its' correct position and worked its way completely to one side of the cylinder wall. In this position, only one part of the piston was being supported by the gudgeon pin and due to the high unsymmetrical forces, the piston broke." | |  | Photo of Jabiru Engine installation - from Pacific Flyer Magazine August 1998 Note: Rocker Covers - Engine is 2200 early model (like the one I flew behind) | | |

In 2007 I was able to get the photos from the Photographer for News Ltd (Robert Pozo) that visited the crash site on the afternoon it happened. I had ordered the engine be sent to CASA or ATSB in Canberra for a totally independent strip-down analysis. My instructions were not followed.

| This is an enlargement of part of the above Photo. Is the squarish shape of the visible lower part of the Cylinder Head the version below or was it some publicly unknown experimental "cross-over" model - as the next known model of Head has a markedly changed Rocker Cover and attachment system. Who knows ? This engine was supposedly CASA certified. | | |

Note: Cylinder Heads and Rocker Covers. | JABIRU ENGINE UPDATES SECTION I was told the the Jabiru Aircraft I crashed in had "the latest engine and modifications". Now with the benfit of hard experince and hindsight, I would ask and check exactly what version of what components have been used and compare it to the latest list - which could be assumed to give the most reliable engine. Where is such a list ? I found this document on an AvidFlyer website, from 2006, written by Kerry Owen, compiled from a Jabiru Parts Manual from the year 2000.

SCHOOL - so must be fully CAA/CASA Certified (like Cessna or Piper) ?? From 1997, a Jabiru Aircraft Flyer sent to Australian Flying whilst I was writing the "Sport Flying" Column. Jabiru clearly imply their aircraft are "Certified" and can be also used in the "VH" version by General Aviation Flying Schools. I was quite clearly told by CAA/CASA in the 1990's that GA Schools can not use Homebuilt or Kit Built Aircraft. Can only use factory built and must be CAA/CASA Certified. So in the 1990's Jabiru's must have been CAA/CASA "Certified". Anyone who can provide evidence that this was a correct assumption, please let me know. Here's a photo of VH-NQA in flight in the 1990's. VH-NQA was used by the North Queensland Aero Club, in Cairns. email with your question or experience for us to put on our website - click on this link
