    I agree with Brendan. I reckon the piston is not returning after braking. Pull the whole wheel cylinder apart & check for rub marks grit etc, clean everything meticulously, reassemble & make sure moving parts i.e. the piston moves freely.

    Make sure you reset the spark plug gap to the minimum (about .020 in) for the cold weather. That and make sure the throttle is fully closed & the choke fully on. My gen 3 3300 always started even when it was pretty cold with a light frost with the plug gap about 023 but when I went out west and there was ice on the fuselage I could not get it to start & flattened the battery. I took all the plugs out, closed the gap up & at the time not with any feeler gauge, just a good eye, got a jump start & it fired almost straight away.. Never had a problem since as I change the gap when it gets cold every year. If all that fails get a cold start kit from Jabiru. It is basically a gruntier coil. It replaces one of the standard coils & provides a much bigger spark on one of the plugs in each cylinder.

    Given both are in the tail and it was left intact sticking out of a building extraction of the data should not present a problem. Then again stranger things have happened before.

    Bird Strike. There is no indication of birds in any videos but then the video quality is fairly poor. If you can't see whether there was any flap deployed you'd hardly be able to see birds either. In the Korean Jeju Air 737-800 crash last year at Muan none of the early videos showed birds but that was the cause of one of the engines to fail completely. Later videos, possibly enhanced, showed a large flock of birds.

    I agree about power loss. Even if the flaps were retracted and the wheels down I would have expected the aircraft to at least maintain altitude under full power once it was at 400 feet. The initial climb out was reasonable especially in 40 deg heat & fully loaded with full fuel.

    Many places have automated response units which is a good way to check if your radio is working. That is if the airwaves are not busy. The one at Grafton will respond if there has been no other received calls in the previous 5 minutes. Also if you are hearing radio calls you at least know the receiver is working. There is no harm in asking for a radio check if other aircraft are in the vicinity.

    Aviation is littered with scenarios that should never have happened, many when all the procedures and communications were carried out correctly. CASA uses a lot that ended up as near misses as case studies in the hope that we can learn from them. While we continue to learn and hopefully reduce the likelihood of such events, we will never eliminate them. Every now and again, against all odds the holes in the proverbial Swiss cheese will align and we will go through the process all over again.

    Water is like concrete if you hit it at speed & it will hurt. Water skiers can attest to that. So just like bare foot skiers with appropriate skill and speed the wheels won't dig in. If you don't have both of those it will be a very expensive exercise.

    Most are probably MAGA nutters.

    By the time they get this to market it will be just about all over for internal combustion engines even for aviation. All the Japanese auto makers are struggling right now losing huge ground in their biggest market, China.

    The answer to that vid is "It depends". Practicing over an airfield is easy and the windsock will guide you to the best runway. In the middle of nowhere everything changes when the engine fails for real. You forget half of the engine failure procedures though trimming for best glide & looking for a landing spot are the 2 most important if you can't get the engine going as in changing from the empty to full tank etc. Altitude is your friend with no power so then you use that to your advantage so when you have identified the landing spot make the most of the altitude you have.

    Quell is a well know local brand & part of the Kidde group founded in the USA in 1917. They produce fire protection, control and gas detection systems. The CO detector with replaceable batteries can be purchased from stores for about $35.00. Both the 10 year battery & replaceable battery models have a 10 year operating life. I'll probably replace my existing unit with one of these though it is a bit bigger than the unit I have but has pretty much identical features. It will be almost certainly Chinese made like just about everything else.

    Not sure of the brand but like most things it is made in China. It is quite compact at about 70mm x 70mm. I have it velcroed on to the panel. It cost about $30.00 5 or 6 years ago

    Me too. The engine was running perfectly & I shut it down but could not get it to start again. I did all the trouble checks and found that the mags had to be on before it would run. Who woulda thought.

    Up to 10 parts per million is considered normal CO background level. Maximum of 30 parts per million is safe for a maximum of 8 hours exposure. From there the maximum exposure and time varies by individual. 100 ppm can be endured only for short periods not exceeding 30 minutes and can be accompanied by headaches and breathlessness depending on the individual. Above 400ppm can be fatal. Different authorities have higher or lower levels with some saying anything over 35ppm and you should leave the area immediately. Some monitors start going off at very low levels. Mine has a digital read out that displays the level from 30ppm and flashes a red LED and starts to alarm at 90ppm with loud beeps and fast red LED flashes.

    Incat has produced some of the most innovative catamaran ferries on the planet and are a world leader in this field and now with electric propulsion. I read about this project a year or so ago. There is a great future in building ships like these & a great export earner for the country. Far better than digging stuff up and sending it offshore so someone else can reap the benefit.

    The longevity of EV batteries manufactured since 2022 has shown that most will outlast the vehicle they are installed in & with CATL providing up to 2 million km warranties on their current batteries plus the ability to charge them in the same time or less than filling up a tank of diesel or petrol reduces the benefit of a swappable battery. Most of the earlier EV batteries are currently being repurposed for fixed storage but if that market becomes saturated or the battery is too damaged etc they are ground up to form black mass and over 95% of the minerals are recovered for recycling.

    At the current rate of battery development I can't see much future for internal combustion engines at all. CATL have just unveiled a new EV battery that has a range of 1500km on a single charge and can be recharged to provide 520km of range in just 5 minutes. https://carnewschina.com/2025/04/21/battery-giant-catl-showcases-three-innovations-1500km-range-battery-520km-in-5-minutes-ultra-fast-charging-and-2025-mass-production-sodium-ion-battery/

    You need a RCD (residual current device) for this protection. These can be combined as a RCCB (residual current circuit breaker). I have these installed in my house.

    For clarification the wiring from your meter box to all of the 3 pin sockets and light fittings in your house is generally TPS (thermoplastic-sheathed cable) and is called "twin core and earth" and comes in numerous diameters. In most houses lighting circuits are 1.5mm, 3 pin socket cables are 2.5mm with things like ovens and cooktops 4mm to 6mm. It all depends upon the current required and the distance the wire has to run. The colours are Live = RED, Neutral = BLACK and Earth = Yellow/Green. That's it. Wiring from the socket or fitting is usually Live=Brown, Blue = Neutral & yellow/Green =Earth. Specialist equipment with comms capability can be different colours depending on the job it has to do.

    Rain all day today to the North. 80mm at home. Very wet Anzac parades. Not looking flash for tomorrow either.

    Boeings stock keeps declining after their disastrous failings ever since the Max 8 crashes. When things go bad a company usually begins to divest interests that are not core to its business. The US government is keeping Boeing going with its military contracts. Their foray in to space didn't go well leaving Astronauts stranded & doors falling off because they forgot to secure the bolts doesn't inspire confidence. I'd say that Ozrunways/Foreflight will probably become combined but will be in better hands (possibly).

    Plus a different wing configuration & no prop ducting

    The photo is not as described. No front canard or retractable nosewheel. Either these were dropped or they were a later modification.
