The CH701 was flying straight and level at 70 kts on a cross-country flight. While reaching for a water bottle, the pilot accidentally snagged the left-hand inner door handle, releasing the door. The door instantly slammed up against the bottom of the wing, with such impact that the outer handle punched a hole through the wing skin. The pilot grabbed and held the door with one hand, and slowed the aircraft. But the front hinge had broken with the initial impact, causing the door to skew somewhat across the wind. The resulting force was so strong that the pilot couldn't pull the door in again, even at 50kts. Eventually he had to let it go. When it went, it hit the horizontal stabilizer, causing considerable damage to the leading edge, breaking the left forward mounting bracket (7.H.2.6), and bending the right forward bracket. So the horiz stab was then somewhat skew to the fuselage. The aircraft was still flyable, but with considerable drag and a left yaw bias. The pilot continued on to an airfield and made a successful landing.

An early model. They were very flexible. In the re-build Hans used .060 instead of .025 for the corner gussets, and that made a much stiffer and better feeling door. Basically I think any door has this potential if the airflow catches it just wrong, then everything will change instantly.

My kit came with a predrilled holes in rib#7 for 6W6-10 channel. If I follow the drawings, the upper edge of the lower bracket should be 70mm from the bottom of the rib at center of the channel. But centers of the predrilled holes are just at the lower edge of the bracket. I'm going to make a set of brackets 10mm longer so I'll rivet the channel together with the bracket and ribs with 3+2 rivets on the lower bracket. Anybody has better solution? I don't want to make a groove in the bracket to make a space for the rivets, it would be just 5mm from the hole. -------- Pavel CA Zodiac XL N581PM (Reserved) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=175107#175107 Attachments: http://forums.matronics.com//files/cimg1443_166.jpg http://forums.matronics.com//files/cimg1442_101.jpg http://forums.matronics.com//files/cimg1441_192.jpg ________________________________ Message 13 ____________________________________ Time: 01:53:58 PM PST US From: "JG" Subject: Re: Zenith-List: Re: CH701 Door Warning Thanks for your supportive comments Rick. Those heavier gussets in the corners really made a big difference in the stiffness of the door. That was an early model door, and they are a little bit different from the later model in Hans own aircraft. In the early model there was a gusseted corner at the bottom of the trailing edge, whereas the later model has the tubing sweeping around a radius corner in one piece. That gusseted corner is the source of much of that flexibility. The main part of that latch is pretty standard, but the sliding rod to the trailing edge is a new idea borrowed from a Rans S7. We still have to get it to work on the aircraft, which is a 6 hour drive away. I'll post more photos when it's fully installed.

This weekend they had a camp out at a near buy airport with several activities that will allow the boys to get their aviation merit badge. Among the events the local R/C aircraft guys brought out their models and let the kids fly them with a pretty neat dual control rig that allowed dual controls. While one of the kids was flying he brought the model into a climb and the guy teaching him told him to add full power. Instead of pushing the throttle stick forward the scout pushed the elevator full forward very quickly. If you are playing along at home you can probably guess what happened next. The wings folded up then departed the aircraft. What really amazed me was the metal spar that was a rod that ran the entire span of both wings. Play with the litter that had a few minutes before been a nice model I tried to bend the rod back into shape. I couldn't do it. I grab my friend and both of us working to gather had a real hard time bending it. The moral of the story... excess G's and over control are a bad thing. -------- W.R.

The function of the fuse is to protect the wire, not the pump. You do not want the wire to overheat and start a fire. So I suggest you go with a fuse of the largest amperage that will not severely overheat the wires. Check out Table 11-3 in AC43.13-1B. If you're using AWG 22 wire, use a 5 amp fuse.

If I understand you correctly, you are concerned that a momentary, short circuit load on, e.g., a fuel pump power lead might blow your main system fuse. I'm just a reader of the aeroelectric connection, and most of what I know about airplane electric systems comes from there. And, God knows, I don't understand all that I've read. So, take this with that in mind. I haven't seen your schematic, so I'm not sure what the function is of the 30 amp fuse that "protects the entire electric system." I know that the Jabiru 3300 alternator is rated at 20 amps. That says to me that the steady state load on the electrical system should be less than 20 amps (so there are some amps left over to recharge the battery after starting). A transient load can be much greater than 20 without compromising the system--what does your starter draw? More than 30 amps, I'd guess. So, if the 30 amp fuse is designed to protect the cable from the battery to the main bus, you might consider a larger cable. Then you don't have to worry about blowing the 30 amp fuse. If you're happy with 30-amp capacity, you might consider using some sort of slow-blow 30-amp fuse so that a momentary 5 amp overload on some circuit would not blow the main fuse. (Something like the LITTELFUSE JCASE HIGH AMP FUSE, PINK 30 AMP (JCAS30BP)) The fuse-to-protect-the-wiring approach makes sense to me. Other approaches might work for you. But I think that the last thing I'd want in my airplane is a fuse to the fuel pump that is operating right at the limit of its capacity.

As a general rule, the fuse should be rated for at least 125% of the maximum continuous load on the circuit. The primary function of the fuse is to protect the wire feeding the circuit, not to protect the device being fed by the circuit. It doesn't hurt to have a larger fuse than the device is rated for, as long as the wire feeding the circuit can handle it.
