Re: [DOG mailing list] In Flight Emergency Actions Part 2 Fire!

 get slightly excited occasionally when I operate the 
cabin vent and isn’t the only one of that variant to do it. I don’t think I 
would like to try it canopy off.

  

In any event any canopy has the ability to remove a tail plane if it ends up 
hitting it at speed. It depends on how cleanly it departs.

  

I work on the principle of being extremely diligent to mitigate the chance of a 
fire. I can think of 3 right offs and one of them fatal in the last 6 years 
from fires where that principle was left wanting.

  

Richard and I spent time at every DI for weeks trying to track down a fuel 
smell. We ultimately found it by due diligence and it was a widow maker waiting 
to happen.

Put the wind up us but as we were diligent we found an fixed the problem. 
Others surprisingly accept such things and have even said to bystanders that a 
bit of a fuel leak it is normal. That fatefully in a recent instance resulted 
in the pilots death from inflight fire the day after he said it.

  

There is nothing normal about a fuel leak other than doing a fuel drain. Too 
often I have encountered aircraft with leaks and the pilots are oblivious to 
the risks.

  

The best one was when I discovered a 1litre a minute leak in a G109 just 2 
weeks out of annual. I was doing an engine run after a carby change with the 
cowls off and a fire extinguisher in my hand. The owner pilot ignored the 
briefing and watched his instruments as I was indicting cut power. We got there 
after a very long 25 seconds. The fuel was running directly onto the exhaust. 
Only when the boost pump was running though. Later the pilot commented that 
that explained why his passenger had reported the smell of fuel every time they 
taxied and also partly why he was burning 22lits and hour (Leaking during 
takeoff/climb and landing with the boost pump running).

To this day he doesn’t admit it was overly serious.

He flew from Byron Bay to Burketown in that state with 5 stops. He then flew 
another 5 mornings before I found the leak.

The guy who signed off the aircraft annual is also very much to blame.

  

  

Cheers.

Nige.

Good question Kurt and one we would have all thought about at some time.

  

Would depend on a number of variables. Given the width of the Dimona canopy the 
probability of wiping out the tailplane on jettising would have to be high let 
alone balance issues Andrew mentioned. 

  

Windspeed in the cockpit wouldn't help either. I remember the blast in the 
cockpit when flying the Blanik without the canopy all those years ago (sorry 
Andrew!).

  

So I think I'd only do so if I was suffocating and/or burning, not while still 
able.

  

Nigel, Andrew or anyone else aware of any other in flight jettison events?

  

I was going to suggest throwing the canopy as soon as you can free your hands 
to do so on the landing roll but on second thoughts you would then be more 
greatly exposed to the effects of the fire while still moving.

  

Would a severe ground loop on touch down assist directing heat and smoke away 
from the cockpit and drastically shorten the landing roll?

The canopy jettison has the potential to affect the cg and potential damage to

I know of a few TMG pilots that have been involved in the 3 fire events in

Hi Dave,Just thinking about the Dimona's behaviour in a severe groundloop. 
Agree that immediately after touchdown wouldn't be the best time to initiate 
the groundloop, but I think I'd be comfortable commencing one soon after.
The H36 is built like the proverbial Sydney Harbour Bridge. My understanding is 
that it rarely (if ever) goes up on its nose or over on its back in mishandled 
landing accidents. The airworthiness guys might like to comment on this. When 
you think about the loads in a groundloop these are towards the outer wing and 
downwards. Slamming the outer wing down isn't what I'm proposing but once 
getting it down and then holding down firmly while applying full opposite 
rudder. The undercarriage bow would probably hold up throughout albeit with 
damage and partial removal as the rod ends distorted/failed. During a grounloop 
its surprising just how slow the action seems as you dissipate energy even 
though it isn't that slow.
If the pilot assesses that they still have a couple of minutes before being 
consumed by fire then hold off maybe but I would rather suffer a fracture or 
cuts than burn or be overcome by toxic fumes.

We flew a fellow the other day who was in management with Peregrine when you 
worked for them and knew you. He has a British accent and was responsible for 
most of the continents excluding Antarctica. Will see if I can look up his name 
but that description probably sound familiar.

With the loss of a well known and highly experienced glider pilot in his MG due 
in flight fire last year, this topic is fresh in the minds of most Aussie 
glider pilots.

Nigel made the point that often a pilot may be unable to distinguish between 
these types of fires during flight. Depending on the location and nature of the 
smoke source within the cockpit that may well point to an electrical fire but 
does it really matter which type of fire you have to contend with?

The reality is that if it continues to burn (and it will) one type is no less 
hotter or catastrophic than the other although an electrical fire may take a 
little longer but be more toxic!


As with the previous section on engine failure during early climb out, the AFM 
contains some sound advice and Nigel and I would argue, some less sound advice.
in my opinion it badly understates the urgency to get the aircraft down onto 
the ground asap.


 Recommendations:

1. In the event of ANY fire, carry out ALL of the AFM actions listed for BOTH 
Engine and Electrical fires.

2. WHILE doing the above, apply the greatest side slip that you can manage and 
pull full spoilers as soon as your left hand is free from turning off and 
pulling things.   (The side slipping is for the reasons provided in the AFM and 
also to redirect heat away from the canopy and cockpit)

3. Fly your Dimona through a wide spiraling descent so that you can survey the 
best landing areas in your immediate vicinity on each turn and plan for a rapid 
arrival at one.

4. Forget "Execute normal landing from a glide" just get the bloody thing down 
so that you can egress and move well away upwind, while it burns.



My Comments and as usual, appreciate your thoughts and feedback:

1 & 2. I plan to sit in the cockpit before startup on occasions, close my eyes 
and visualise a fire. No time for finding and reading a checklist with the H36. 
I'll just rehearse shutting everything off while entering a rapid descent using 
side slipping and full spoilers.

2. Its well worth staying current in side slipping. Caution required near the 
ground close to roundout but practiced at height and then applied by joining a 
high/steeper final occasionally provides a
