Loss of Power - Forced Landing

I just wanted to share my recent story of my Forced Landing. All things considered you can technically call it a "Soft Field Landing".

So I am 60 hours into my plane, which has an IO320, EFII System 32 set up. This things runs smooth and starts like a car almost unbelievable how good it runs. Decided to take a flight with another pilot buddy on August 5th, 2025. (NOTE: Oil Changed 5 day earlier, run up 3 times, no issues) Departed KBZN headed towards Twin Bridges all is normal, leaned the engine back everything looks good almost 1 hour of flight time goes by. Heading in to do a flyover of Twin since that airport was closed for new runway, upon the departing climb at roughly 1500 AGL, 2 miles out the engine just starts coughing and running rough. EFIS showed #1 cylinder go dark ( No Readings At All). Quickly losing altitude and unable to create more power we had to make a choice. Option #1: Turn back and try and land somewhere near or on the airport with lots of big tractors and machines everywhere. Option #2: Pick a place in front of us field or road. We went with #2. Took about 5-10 seconds to choose a landing site. That's when the reality hit, we are going to probably crash, also at the same time that is when my commercial training power off 180's kicked in. Flaps full - ballooned up to get over the power lines in the way, once over realized i was too high and a little slow, nose down picked up airspeed back to 80-85 ish... starting to flare. Buddy yells deer in the path ( I instinctively pull up) its ok i have enough speed for it, however now that i got a bit higher the field is running out and we are still floating. (thoughts in my head - Keep nose gear off that ground no matter what, once your wheels touch). I touch right gear first, then left smooth as could be, nose is off we are doing a wheely, however the end of the field and what is normally a ditch is fast approaching. (Thoughts in my head - let off break pull back and maybe we wont flip over and just hit the ditch with the bottom of the plane, may or may not live). When that ditch came we somehow kept rolling. Holy hell there was no ditch just flat field. Kept nose light maximum breaking we come to a complete stop. We lived, somehow we did it. Not a scratch on the plane, somehow I picked the best maintained farm field and missed every gopher hole there was.

Findings of what went wrong:
Upon retrieval of the plane - found that both #1 & #3 Cylinder Fuel Injector Ports sheared off. #3 what held in place by a clamp hence why it was producing some power. #1 completely loose - that is why #1 went dark on the EFIS.

Cause: The fittings were aluminum and the fuel hose was apparently too tight and did not leave enough room for vibrations. Basically slowly tearing them apart. I also believe the weight of the overall set-up could have not helped also. You can see the hose in question from the #3 back to the fuel pressure regulator.

Lessoned Learned:
1. Once you pick your landing site - Commit and stay committed
2. Treat every landing like a soft field that way when you have to do it for real you know how
3. Learn how to wheely your plane (I was taught this and practiced it regularly always thought it was fun to do)
4. Practice power off 180's
5. Look for single point failures and include them in your preflight inspections

Outstanding job getting the airplane down safely and in one piece - superb piloting!

Curious about the injector mounts - what vintage are they? Old kit, or something fairly new out of EFII? I ask because a few years back, one of our well-known race pilots with an early EFII system had virtually the same failure, and it dumped fuel all over inside the engine compartment as he found an airport under him to land. A very close thing. I talked to EFII about it, and got a fairly cool response when I suggested he have all his customers check for a problem - he said he’d already made the parts stronger, and less prone to this failure… but what about the existing units in the field? He wasn’t terribly concerned. I thought he should be!
 
Great job on the forced landing. Glad you are OK.

Compare the FlyEFII design to that of SDS. Welded bungs in the intake tubes with the fuel injected against the airflow versus CNC machined injector housings that replace the stock injectors. Yes I know the latest FlyEFII injector mounting design copies what SDS has done for years...

You really want to open this up again?
 
Took a couple of steps inside a hangar where a guy was working on an RV. He very rudely stated "this is a private hangar---------"
I watched him take a long piece of duct tape and "install" it inside the induction scoop. I walked away thinking this guy will probably kill himself and there is absolutely nothing I can do about it.
More recently I landed at a mid size airport, winds light and variable., high elevation, single runway, I had already decided I was done for the day. A short time later the wind was straight across the runway and variable both sides of 90 degrees, probably gusting to 20, maybe more. I watched a taildragger RV land and repeatedly almost lose control from first touchdown point until almost stopped. All over the runway and almost dragging one wingtip and then the other.

Jeffrey, thank you for sharing this with us.
Very grateful both you and the plane stayed scratch free.

It was sent to me in 2019-2020, It was the older Aluminum parts. During 2022 they upgraded to a new steel setup, however no email or update was sent to me. Getting the new steel set-up sent to me now. Going to re-think how this set-up is though. Probably going to a fuel log with 4 ports so I can have each cylinder with less weight and more supported once I get it home, very similar to what SDS does.

Bob, do you not think this design (flawed in my opinion) is worthy of discussion? This could easily have cost someone their life if the failure had occurred on takeoff or over inhospitable terrain. Great to hear that the OP’s skills and training kicked in and there was a successful outcome. And clearly it’s not the first time this failure has occurred.
 
Hello Jeffery,

Thanks for your post, I am glad you are OK.
I have the same set-up and also of the same age, so I am following this with interest.

On your Facebook post it sounds like you are convinced the housing failed due to over-torquing.
I was wondering why you think so, is it something you have been concerned with, since the installation.
Can you elaborate a bit about that?

I had no idea that nowadays there is an upgrade to steel parts available. Can't find anything on the website.
This part of the EFII ecosystem can use improvement. I have an early System32, same as what you have and have no problems investing in system upgrades.

Turns out it was not over torqued. Robert believes it to have been from the Fuel line from #3 back to the fuel pressure regulator not having enough slack and creating the failure. Both #3 and #1 were broke. #2 & #4 seem to be fine, there is a little more flex in the hose coming from the fuel filter. However with all that said, I think i am going to completely change this set-up and instead of a roundabout from tank, to #4, #2, #1, #3 with the fuel line T's. I am going to go with a fuel log and have 4 ports going to each cylinder and having each one supported directly to the rocker covers. Its a modified adaptation from the SDS system while keeping the EFII components. You can see on this picture the hose in question. Yes there should have been at least some type of communication that there was an update to the system regarding steel fittings. I am not placing blame, it was my plane and I am ultimately responsible for it. I am just happy I get to continue living life and possibly flying.

That sounds all good.
I think I 'm going to do the same.
Thanks!
