1. Yes, you can get instruction in your own home built. Build the plane, get someone to test fly it, get instruction.Bass Could you elaborate on this please ?

Once the wing is removed and , there is nothing to hold the flap in position and , it will completely lower. The starboard -

' in position ' wing flaps , appear to be retracted .

Bob

Thanks for that Alf . Could have been worse I guess . Those SWER lines are a real pain in the butt !

Bob

Good point about the fuel in the wings Spin . It certainly appears that the wing has been removed at the scene . Lets hope they did'nt use a portable saw , if they did maybe RAAus should be putting out some general notice to firies , regarding the potential of a major explosion .

Bob

I recently became aware of another incident involving a Jab near ,or at Broken Hill last week . Reportedly hit a power line and is in hospital . Would like to know more if anybody has any further info.

Bob

The wings look to be too long for a J160 , and the port wing appears to have a winglet . A J170 would be my guess .

Bob

" farri " - Anybody heard how Frank fared with Yasi ?

Bob

Frank ,

There seems no doubt that this one will be the ' mother of all cyclones ' and that pretty winter paradise of yours is set to cop a hiding . Can only echo Spins comments/concerns that maybe a fast trip South may well be in order . Anyway, whatever considered course of action you decide to take, we wish you well .

Bob

Russ ,

The guys in the Townsville control tower are very accomodating , as are the guys at several other bases that shall remain nameless . On a recent trip to Townsville , and looking for a suitable ALA with parking for a week or so , I checked with the control tower just in case they knew of some area that was not in ERSA etc. Their response was " come in here , we will vector you in as long as it during a quiet period of the day ". I mentioned that I was a RAAus pilot with no transponder, but that did'nt seem to concern them . Be aware that if " Murphy" appears , and something goes wrong , like you get out of control and damage some civilian or RAAF equipment or even worse cause personal injury , whoever provides your liability cover will walk away and leave you holding the baby . In an emergency its a different matter of course and all these conditions are waived , but our authority does not currently allow us access to Controlled airspace .

I'm sure all Jab owners are watching , with more than a passing interest , to see how this issue is resolved. Like yours until the failure , mine also operates without fault , starts instantaneously irrespective of time since last use , with normal pressures and temps . Runs extremly cool (around 250 F) at cruise with CHT's monitoring both back cylinders . It (#A 2787 ) has been in service since March 2009 and has done 190 hours . It is the hydraulic lifter model , fine finned heads with the old external rocker lubrication system . The aircraft is flown and maintained solely by myself and uses Avgas exclusively.

Updated 1 hour 11 minutes ago

• Map: Toobeah 4498
   
   
  

A man has died in a helicopter crash south-west of Toowoomba near the border of Queensland and New South Wales.

His helicopter crashed into powerlines at Toobeah near Goondiwindi shortly before 3pm (AEST).

Emergency services had difficulty reaching the flood-affected area.

For what it's worth , I just caught the tail-end of Channel 7 news , Melbourne covering this story . The aircraft shown was on a sealed road and more like a Cessna but definately not a Jabiru . The pilot's name was given as a Mr Mancur . !!!

Bob

Just a point fellas . Josh's name is " Bigglesworth " , not " Biggles "

Stixy ,

I don't have an artificial horizon or a turn coordinator , so the "wings level" on the Garmin 196 is at least something , if you suddenly find yourself in cloud , which of course you should'nt , but .............. .

Regards

Bob

Hi Stixy , Would be interested to hear your comments on its operation . Does it have "wings level" indication , and how do you rate it against the Garmin 196 for instance ?

Regards

Bob

Another impartial and well researched post that we have got accustomed to from our friend - 'Diesel' !

SSeeker ,

The POH , of course ,should be correct but I remember mine referring to " adjustable seats " in the J160 . Of course no J160's had adjustable seats to my knowledge . It appears that the POH takes gets forgotten at the time for more important things but in the end these things sort themselves out .

The advice from 'jetjr' and 'JabiruPhil' is quite correct . The air to the carburettor is filtered , irrespective of whether carby heat is used or not and , as stated , unlike some other a/c , this has been a feature on Jabiru's from day one . And yes , the air is heated by a simple method of heat transfer from the exhaust muffler , and the flap valve is on the inlet to air filter , which then passes through the paper filter to the engine . As regards the cabin heater , and as 'Jetjr' indicated once again , the heated air comes from a different heat exchanger which is 'grubbed' high-up on the exhaust pipe . Resembling a jam tin with both ends open , and slid onto the exhaust pipe , with two openings - one for the cold air inlet , connected by hose ( scat-hose ) to an opening at the front of the lower cowl , and the other opening , connected by another hose to the on/off flap . This flap is designed to be either open or shut , although this could be defeated and air drawn from inside the engine compartment , near the firewall . Even with correct operation ie. fully pulled out , it appears possible that some minor leakage of hot air from within the engine compartment may occur due to . When open , ie. the 'Cabin Ht' knob pulled out , it is designed to allow ambient air to enter through the opening in the front of the lower cowl , pass over the exhaust pipe picking up temperature , and entering the cabin through the firewall . If the hoses are damaged , the flap is not fully open ( an 'over-centre' spring arrangement ), or the engine to have a small exhaust leak , which is not all that uncommon , it is possible for carbon monoxide gas to enter the cabin without the occupants knowing , and they will soon be off to sleep . For this reason it is good airmanship at all times , and particularly when using the cabin heater , to closely observe the CO monitor , located well within view of the pilot of course , and note any colour change , and if so , shut the heater off immediately , fully open the vents to purge the cabin air , and have the fault investigated ASAP . Of course you will have checked the 'use-by' date on the CO monitor, and you will know that it current , and therefore indicating correctly ! . I believe that it is important to always have the fresh air vents open a little , even though it may be cold outside . If the air flow through the side vents seems inadequate , check to make sure that the extraction is adequate and is not impeded . Even with 100 knots of positive pressure at the fresh air vents , there needs to be a negative pressure at the outlet to promote a flow , and most of the extraction seems to be achieved via a torturous path out through the ventral fin . I think the later A/c have a vent , similar to the side inlet vents , located beneath the A/c . On a broader note , the systems on a Jabiru , and many other A/c for that matter , are simple , and it is good airmanship to be familiar with all aspects of their operation . One day it may save your bacon !! . Have a talk to your L2 and get him/her to explain the systems , or alternatively contact many of the knowledgeable Jabiru owner/builders , who will be only to happy to help . PM me if you need .

Bob

I think you will find that it depends very much on the diameter and pitch of the prop . With a Jabiru prop you should get around 2800 RPM with a 60x42 and around 2700 RPM with a 60x44 , for other props I suggest you ring Jabiru .

Well expressed and accurate comments .

Bob ( J160 owner/builder )

Hi Ken ,

Welcome to the site and recreational flying . There are many of 'us oldies' here ( I only started to learn at 62 ), so that may make you feel better . The J160 takes a bit to master, particularly on touchdown and rollout , but other than that , is a nice predictable a/c to fly - mine has 80 hours up now and I would'nt want anything else .

Regards

Chris ,

The wing carry through beam is a critical member and without close examination it is difficult to determine its integrity . The same can said of the lower carry through beam that takes the wing load via the strut .To replace these would generally be considered as beyond the scope of the average home builder , and they are in place before the kits leave the factory . The other bits and pieces ( elevator, struts , wings etc. ) can be purchased , and you would need to have or develop skills in fibreglassing . I have seen aircraft at the factory in this condition , and certainly they can be repaired , and the carry through beams can be replaced but , once again by the people that make them .Their positioning in the fuselage is absolutely critical and is done in a jig . There is also considerable work involved in replacing the w/screen and of course a full respray . Both wings may need replacing for one reason or another . The prop has struck something , probably under load and the engine will need a complete stripdown . It is an older model engine , and at worst will cost around $15,000 to replace . Interestly the SK is getting on now and yet the Rego appears to be recent . Maybe one of those 5+ year kit builds with low hours . I also seem to recall that this model with the small rudder, lacked some authority , although having said that , I did my licence in an LSA with the same size rudder and it seemed to be OK to me . These are just my initial thoughts , as much more detail ( component costs etc. ) and close inspection is required , desirably by someone with intimate knowledge of Jabiru's and composite construction . Just finally there are many 'good' Jab's for sale in the mag. each month , which may not have been subjected to this sort of treatment , and may end up costing a lot less than this . Do you know if the a/c was insured ? , maybe the owner was paid out in full . Caveat emptor !!!

Bob ( J160 kit builder )

Yenn ,

I don't believe that is possible . The vents going to each tank come off a common connection from the head tank ( located under the passengers seat or, in the case of a factory build , behind the passengers seat ) and can vent into either or both tanks .

Bob

Yes Jack , you are quite right , however the earlier Jab's , certainly J160's anyway , had nothing to prevent reverse flow . My hangar partners kit built , around 2006 , does not have, but mine purchased Nov 2006 does have the small poly balls . Often if you see an early J160 with full tanks , and doing some fairly tight turns directly overhead , on a reasonably cool clear day , the vapor trail from each vent will be clearly visible . Good idea to test with blow/suck to ensure the balls aren't gummed up . And Geoff, it is possible to get a vapor around the fillers particularly with full , nearly full tanks , with the a/c on a lean . I use a smear of Vasolene around the 'o' ring and also on the contact area . This can help , but then again maybe it is time for a new 'o; ring !

Regards

Bob

Correction - well done GraemeK
