We have hundreds of birds in the Rock River valley at Moline airport. They tend to all lift into the air at once and sweep across a runway when a plane is taking off or on approach. We have strikes all too often and I've had close calls. One occurred in August of last year,, "601EZ was pulled from the hangar and a twin-engine plane sat quietly on runway 5 while people walked around it. I did a preflight and checked with the tower. The pilot had reported a multiple bird strike. 3 hit the nose, 2 hit each wing, 1 hit the windshield, and one went into the engine. He taxied off to the parking area." It would be really great if anyone has a solution for these bird hazards.

S. unless it is a high-intensity strobe with 400 effective candela.

Some folks >are telling me that I need a red beacon on the tail, >other say I need nothing. Can't find anything in the >archives. I don't think there are any regulations requiring lights for use in daytime. It is common practice to use as much lights as you can find when operating in high traffic density airports. Something like a red flashing beacon might be helpful in that situation. Landing lights are quite common in that situation, but they take an awful lot of power. The red flashing beacon is customary for night operations on the ground to warn all around that there is a spinning prop to beware of. It can't hurt to do this in the daytime too. The bottom line, in my opinion, is a red flashing beacon would be nice but you can get away with no lights at all if you are sure no operations at night will be done. (I am putting minimal night lighting, position lights and strobes, on my plane to cover the possibility that I will find myself operating at night even though I am not supposed to do that.)

It is a beautifully built aircraft. Sporting a full panel and a Rotax 912S 100 hp. I have flown as a passenger in this aircraft many times. Truly a great light aircraft. More than enough power and for the most part its pretty smooth. I was out at the hanger over the weekend. There was an aluminum airframe specialist there making an inspection of this aircraft. What he found was a little disturbing. The forward stabilizer mounts had begun to stress crack. The small triangle brace on the center elevator hinge had begun to crack as well. The technician seemed to think the damage was caused torsional vibration from the 912S on start up. This aircraft does shake the tail section rather violently as the engine starts. As soon as the engine achieves idle speed or better the vibration goes away. At this time the aircraft has about five hundred hours. If you have the same combination on your airframe I would urge you to inspect these parts on your pre-flight. This is a good example of the importance of good inspection on our experimental aircraft. The repair bill will be small only because it was discovered early.

There are a few other AD's that Rotax has ordered in the 912 series of engines... Will be a good advise that the owner will contac a Rotax Representative or the Rotax online registre with his engine serial number, to see what mods aply... Please let me know if he needs more info... (note, I am no Rotax Represantative, just a Rotax engine owner). Just an idea, hope it helps. Saludos Gary Gower.

It's hard to tell from the picture- I would imagine the original is a pin with grooves in both sides to accept circlips, to keep free movement of the handles. Don't forget- you won't be able to tighten the nut so that it will stay on, unless you get one of the type with plastic locking threads Problem is, your AN bolts and special nuts aren't going to be as cheap as you think, once you figure in the shipping. Unfortunately, they don't make hardware stores like they used to. If it weren't for AS+S and Wicks, we'd all be up a creek. Case in point- the big spring on my Zenith hand rivet gun broke. I looked in 3 counties for 2 weeks with no luck- had to order a close replacement through work from McMaster Carr. $2.95 part came to $11.00 with shipping. Still, better than paying for a new rivet gun.

If you did, that tool doesn't look like it would squeeze a marshmallow, let alone an AD6. Live and learn.

I have the slipper clutch. I had to replace 7H2-6 both LH and RH. After de-skinning the top skin of the Horizontal stab, I also found a crack inside the stab. The cracked brackets were found during preflight. I installed a gusset plate (.040 2024-T3) from the attach bracket to the top fuselage stringer. This will share the load,add redundancy, and hopefully won't happen again. I will send pics to those that request them. Phil Lockwood suggested I send the 912s gearbox in for new clutch disc springs. He said the springs weaken after 300 hours or so and this results in harsh start up and shut down. I also installed the new high torque starter. He said expensive sprague clutch problems can result if the original lower torque starter is combined with worn clutch springs over time. The gearbox is simple to remove and Lockwood turned it around in a day. The price was less than $100. I am preparing to replace my 22001-13 Barry mounts as well. They have them at Wicks. I don't know if they are worn, but they are cheap enough to replace. Regards Dave Smith N701XL 498hr >Do not archive<
