Risk

I’ve been thinking a lot about risk lately. There was a recent fatal Cherokee crash in a reasonably nearby town – nobody knows yet what happened. As a result the local aviation forum is turning up all sorts of theories. One contributor opined that if the CPL/IR grade 2 instructor who was flying the aircraft couldn’t save himself, what chance did the average weekend warrior have?

I commented that I felt that the best way to mitigate the risk in GA was to ensure that we are all current and proficient, and the lack of experience (i.e lack of total hours) may not necessarily influence the outcome of what appears to have been an engine failure. Further, we need to make peace with the fact that there is risk involved in general aviation, in the same way there is risk involved in almost everything we do. Obviously there is some perceived benefit to undertaking the risk involved. I cannot earn a living, unless I am prepared to take the risk of leaving the house and driving to work. Risk, benefit. Likewise, general aviation. Yes, there is risk, and that risk is not insignificant. The benefits for the personal aviator (I hate the term Weekend Warrior) are perhaps more nebulous – but could include significant decrease in long journey time, a visual perspective on the world that few get to see, the satisfaction in taking control of a machine and flying like the birds, and in my case, a very definite improvement in my state of mind (I call it altitude therapy).

Kitty Hawk Breakfast Run – (#31)

I really enjoy flying to new (to me) airfields. I’ve been wanting to go to Kitty Hawk since I got my aircraft. Kitty Hawk is located to the east of Pretoria – about 30min flying time from Baragwanath. It is a very active field with a large number of Vans RV’s based there.

Seriously though, how smart does that shade film look?


The field has a little bit of a reputation as being ‘difficult’ in certain wind conditions. I’m always up for a challenge that fits within my personal limits and experience, so reputation aside, I felt it was worth the visit. I was able to muster up only one other plane from the JLPC crowd – Roger in his Turbo Arrow agreed to join me out of Rand airport for breakfast.

Die Uys Huis Padstal (#30) Airfield

My aircraft is back from annual inspection – what they say about the first annual is all true, sadly – was a lot more expensive than I was anticipating due to the 5 year rubber change, but that at least is done (until the next time – when I may also be looking at a BRS repack……). On the plus side, my plane is back and fit for flying again!

On the basis of the sticker shock from the rubber replacement we decided not to do any cosmetic work apart form installing the sun shade film on the canopy which has helped a lot to keep the cabin cool. I did this myself – it only took 2hours to apply it – a very fiddly job but the end result is satisfactory and seems to do what it is supposed to. It’s a PVC friendly static cling film that advertises 5% visible light transmission. I think it looks quite nice.

Ready to go – note the window shades – very sexy.

The Flight of the Navigator (or something like that)

I’ve previously written about flying in a speed rally – where we fly a set course against our aircraft’s handicap speed. It’s fast and furious and exciting with lots of close up flying. The other class of competition flying is the Navigation Rally, which I was lucky enough to be a competitor in this weekend.

My aircraft is still undergoing annual inspection (well, actually as I write, the inspection is complete – we are waiting on a post maintenance test flight for it to be signed out again), so I was to be the designated navigator for Matthew in the Mooney. Whereas a speed rally is simply flying a course as fast as possible (and reasonably accurately), the navigation rally is quite a lot more complex. The papers that are given to each crew contain turn point descriptions, a 1:200000 topographic map, a sheet of photos of turn points and places to spot and a time sheet based on a nominated speed.

Flying in other people’s airplanes – Classic Mooney

Having an aircraft in maintenance does very little for the desire to commit aviation. Out of necessity (see previous posts on moving aircraft for maintenance), I had left my vehicle in the hangar when I took my plane to Tedderfield so I needed a lift back to Baragwanath – which Matthew kindly offered. Of course, why would anyone go to an airfield unless it was to fly an aircraft – and he was off to fly his (recently returned from annual inspection) Mooney M20C short body.

Matthew very kindly offered me a flight in the Mooney, to which I gave due consideration (about 500msec) and agreed. The Mooney is a very different aircraft from the Sling. The Mooney styling has always appealed to me, there is something about that forward swept tail and the low slung stance which suggests that it will go fast. The Classic Mooney has a very 60’s look about it (which it probably should!) – the very steep windshield and the ‘big gulp’ air intake are unique design features. Even this short body variant’s tail is very low to the ground and I must say that this would worry me quite a lot in the landing.

Aircraft Ownership Maintenance

Annual time….

As I write this, ZU-IBM is in for annual inspection. This should only have been done in October, but the CAA is a bit of a hot mess at the moment, and it is taking 3-4weeks to get the airworthy certificate or Authority to Fly (ATF) after annual inspection so we moved it up a month. I suspect this is mostly because the AMO doesn’t want airplanes stuck on its ramp waiting for paperwork to be completed.

I think it will help to have moved the annual forward away from the ATF expiry date because that should mean that we can do a full year on the next cycle. Anyhow, this does basically qualify as the first year of ownership and looking back, I must say that it has been really good to own the aircraft.

We’ve done a few trips that we would never have done, and the freedom of being able to decide on a whim to go flying is seriously under-rated. So here follows a small summary of the year in ownership..

  • Hours flown: – 69,5
  • Fuel purchased: – 1154
  • Average fuel Burn: – 16litres per hour
  • New Airports visited: – 17
  • Passengers Flown: – 37 (obviously not separate individuals)

Of course, there will be at least one unexpected expense involved and this time it is the 5 year rubber renewal which involves changing every rubber hose and gasket in the engine compartment. It is a bit of a pain and an unexpected expense which could be deferred… but that is not how I want to operate my aircraft. Deferred maintenance is something that I feel will bite one day and will be an issue if/when I sell the plane (yes, that RV-7 is still calling….).

There are a couple of other squawks that need dealing with – for some reason the starboard strobe has decided to call it a day, and the landing light wires seem to get quite hot coming out of the switch on the panel – this may well be normal but it needs to be checked out. The oil pressure still runs lower than I’m comfortable with on the long climbs – although we have looked at the system I think another once-over won’t go amiss. My gut feel is that the issue may be the sensor, but that is the easy way to rationalise it.

Apart from all that, the only other job is to put a decal on the rudder – I’ve long wanted the chequered pattern on the plane so we’re putting it on the whole of the rudder. I trust it will look good. The idea I have is what is shown below…

So, with no plane and hopefully no more surprises… there is little to do but to wait patiently impatiently for news on when Miss Daisy will be back. Will update as and when needed.

Bethlehem Airshow 2019

One of the joys of having an aircraft is having the ability to fly in to various airshows, especially those that you would never have considered attending due to the distance. Bethlehem (FABM) lies about 99nm south of Baragwanath, an easy hour’s flight. It would be a shame not to take the chance to attend what is generally considered to be an excellent airshow.

Secunda Speed Rally – Day 2 – Race Day

Race day dawned clear and calm, despite the forecast low cloud. Breakfast at the airfield was on offer – sliced bbq steak, onion and fried egg on a roll. Unusual, but delicious.

Secunda Speed Rally 2019 – Day 1

I’ve been trying to get involved in competition flying for a long time, but it has always seemed to not work out for one reason or another. I’ve been able to go to see the rally taking place at Middelberg and Springs in the past but haven’t been able to take part. This weekend though, everything seemed to fall into place with a public holiday on Friday and the race being held nearby at the Secunda airfield (FASC) on the weekend.

Competition flying in South Africa seems to be undergoing somewhat of a resurgence at the moment after being stuck for years in a stodgy cycle of President’s Trophy Air Races marred by legal cases and appeals. Three event formats are currently taking place – Speed Rallies, Navigation Rallies and Fun Rallies. They are being held through the country (although mostly in the northern half, fortunately). Fun rallies involve flying a short course in a very narrow corridor, points being deducted for excursions from the corridor. Navigation rallies are plotted and flown to specific times and locations and are the more traditional form of competition rally flying in South Africa.

DIY External Aircraft GoPro mounting

I’m getting a little bored with the in-cockpit got GoPro shots. I feel like there are only two angles really – either out the front or looking at the wing. While these do have some interest, I’m keen to try some external camera shots. 

The problem here is airways going to be how to safely attach a GoPro to the exterior of the aircraft. Safety here is two pronged – one doesn’t want to interfere with the aerodynamic performance of the aircraft. Neither does one want to be responsible for GoPro sized dents in structures or people on the ground. 

I’d imagine the CAA/Police/justice system works take a dim view of damage caused by falling action cameras. Additionally, you can’t simply attach objects permanently to an aircraft. With this in mind I’ve been looking at getting a mount to capture footage like this. 

There are a number of options and ideas to achieve this. The easiest way is to simply use the GoPro suction cup and apply it to the wing. Look. The cup grips well. But I wouldn’t like to bet my GoPro on it. So that idea is out. Then there are some proprietary mounting systems sold mostly on Amazon – flightflix and nflightcam being the two most prominent brands. But they are really expensive, especially once shipped here. 

So I thought I’d have a go at making one myself based loosely on the flightflix tie down mount.
