Dear Listers, Well, its November 30th and that means three things... 1) Today I am now officially 43 years old...

If, for example your engine failed on takeoff and you had to make an immediate forced landing without being able to choose where and without time to unlock the doors, you would not wish to jeopardise your chances of survival further by being locked in. Mike Gregory Europa Club Safety Officer Yes - that is the other side of the story. Same problem is in cars when driving in "bad" cities: doors should be locked to prevent possible robberies in traffic lights but they should be open for possible accidents. Best locks open automatically when crashed. I tell more about my personal safety plan: passenger side door is always locked by pip-pin. That is because no-pilot- passenger (child for example) is irresponsible. It takes only one second to open the door by lifting the lever ("hey what the hell is this?"). When locked w pip-pin there is more time and pilot can prevent stupid or accidentally opening. Notice: when parked pip-pin is a passenger side door lock! Pilot side: pilot decides if he/she uses pilot side pip-pin or not. I think it is safe to use well after take-off when levelled and unlock again well before landing. Of course after emergency landing you can find yourself on it=B4s side locked side upp... By the way - I am not sure - but I think most Cessna pilots do lock both of the doors before take-off. I checked also my Cessna flying manual and there was a clear order: before take take-off do close and lock the doors (this is also for comfort: if not locked you cannot use your armrests - locking lever is on its way when unlocked position). Life and flying is full of choices, happily. I want to point: this all is IMHO. Copy or not!

Mal MaClure in Australia developed a very cheap, very simple way of making the doors safe and stopping the slight bowing that occurs when the fresh air vents are open. Ever had your shirt sleeve gently tugged by the slight draft going under the bottom edge of the door? I've an idea Bob Berube did something similar? He fitted a small nylon wedge to the door and the door frame mid way along the bottom of the door, the two wedges just latch and hold when the door is closed. The door flexes slightly as it latches and unlatches, (don't worry about this) If the door isn't fully closed it won't be latched but you may still get the front shoot bolt in. Then after take off there will be an unusual draft through the gear lever slot, it's caused byt the air being sucked out of the cockpit through the back edge of the door. Mal's mod means you just latch the door and if it's latched, close the shoot bolts. If it isn't latched don't lock it.

I am not convinced of the desirability of having any additional one locking mechanism to prevent opening in flight that might either prevent the pilot/passenger or outside rescuers from opening the canopy in the event of a crash landing. If, for example your engine failed on takeoff and you had to make an immediate forced landing without being able to choose where and without time to unlock the doors, you would not wish to jeopardise your chances of survival further by being locked in. Graham is right: you must FLY THE AEROPLANE. If, for whatever reason, prevention has failed and a canopy door does unlatch in flight, then the handling pilot should think very carefully before deciding to risk holding onto the door if he is flying solo. Chuck Rhoads was fortunate to get away with it ("the landing became interesting because I had never used my right hand on the controls and thus there was no easy to control throttle, trim, etc. The landing actually turned out to be pretty good..."). The Europa will fly perfectly well after losing a door, and it may be far better to have this happen and accept that there will be a relatively minor repair than to risk the far more serious consequences of losing proper control, of which we have been given vivid examples in previous messages.

Once cleared for take off, I closed the door quickly and took off. On the climb out I realised that the rear shoot bolt hadn't engaged. I completed one circuit, keeping speed low, landed, stopped, engaged bolt then took off on the remaining (ample) runway. Naturally I was concerned that I might lose the door, but it was a non-event. Moral of story? 1. ALWAYS check ALL four bolts. 2. During build, ensure that the bolts throw adequate distance into their holes. I recall that there was a mod that came round during my build to thicken the door frames where the bolts go.

It seems that if the duct was slight shorter with a proper shaped lip, something like the Katana Extreme photo attached, may be a better mousetrap?? By having the entrance of the diffuser airfoil shaped, if done properly with the flat side on the inside, it could decrease speed and increase pressure which is exact what we want, and even give a bit of forward thrust.

At the moment it's to early to show what I am doing because I need more tests and experience in flap control. Something for long winter evenings.

With about 50 hours of flight I had the oil return line "carbonize", and burst in flight. Fortunately, no fire but lots of smoke. The oil return line provided by Europa (or perhaps it was Rotax), was junk. I replaced it with a stainless steel braided oil line, covered the line with firesleave, and further wrapped a stainless steel jacket around the line where it comes closest to the exhaust system. 400 hours later, no problem. A better solution however, is to turn the banjo fitting at the bottom of the engine so as to face forward. Then route the oil return line forward to the front of the engine and then backward to the oil tank, keeping the line far away from any exhaust components. A "stock" oil return line, fitted per instructions WILL burn up. Please take this advice seriously.

If you feel air coming from the throttle slot, keep it slow and return for an immediate landing. A few months ago we went to Pine Mtn Lake for lunch and before the return flight spent nearly a half hour with the door open on a hot day, chatting with someone on the field. The door began warping in the heat, so that when I closed the pilot's door, the rear bolt did not engage. Immediately after take-off, we both noticed a breeze coming from the gear retraction slot (it usually sucks air out at this location). All was well at normal climb speed of about 80 kts, but when I leveled off for a cruise climb of 100 kts the door popped open, BIG SURPRISE. The door did not immediately depart the plane, and I quickly noticed that left rudder would bring it back into arms reach. I reduced throttle and yelled for my build partner in the right seat to take the plane, and wrestled the door back and latched it. Although we did not lose the door, we did lose the air strut. In retrospect, I think I did spend too many brain cells on the door and way too few on flying the plane. It's a good thing I had a pilot/passenger in the right seat. I believe the event that finally caused the door to open was not the increased airspeed, but the change in yaw that happened when I transitioned from climb to cruise(climb).

Yes I made the mistake of not checking the rear bolt in about the sixth hour on the plane. Was at 1600ft feeling the air coming through the throttle slot trying to figure why. Door flew open straight up. Before I could even think about grabbing it, it was gone. No damage to airframe at all, just no door and mouth open. Aircraft flies fine just don't try to use charts, a little windy. Built new door and always check doors twice before takeoff.

The original round configuration has the exhaust headers centered in the hole without much view of the cylinder fins. I opened up each hole to the inboard side about 1 inch having the radius decrease as it got closer to the inboard side. Now each nostril is egg shaped with a commanding view of each cylinder fin bank. Special pains were made to extend the lip of the new portion of the hole inside of the cowling to avoid having the air spill off of the inside edge and become turbulent. The length of the edge toward the innermost side of each hole is about an inch deep. It makes for good airflow toward the cylinder fins and presents a good appearance from the outside.
