I was only going for a 15 short hop. First of >all, I ground inspected the plane for about 20 minutes because it had >just had its annual inspection. I took off from runway 27L. I flew >about 8 miles East South East to the city of Pontiac and then headed >back. Everything seemed to work fine. > >The tower gave me runway 22(2,400 ft) because the wind was 220 at 25 >kts. As I approached the runway and slowed to under 100 mph the nose >dropped. I porpoised once and then again. I then went around and >asked for runway 27L(6,200 ft). > >The nose gear light would not come on in this second landing attempt. >Although I didn't know it at this time, the front fork had been bent. >The tower confirmed that the nose gear was not down at all. > >I went up to 4,000 ft and worked with the mechanic's(on a second >tower frequency) suggestions of plus and negative g's to try to bring >down the landing gear. Nothing seemed to help. I then opted to land >without nose gear on 27L. > >In a stable run over the runway at 105 mph(normal touchdown 70 mph) >at an altitude of about 1 ft., I pulled back on the throttle by 1/2 >an inch and pulled back on the stick. The stick hit a stop. I tried >again. The stick hit the stop again. Pulling any harder, to jerk >through the stop, could have caused me to angle up to high. I had to >put power back in and touch down. My intention was to touch down >fast, hold off the nose and pull power, throttle and mixture to stop >the prop. That was the end of my flight. > >If there are any questions or problems, feel free to call, e-mail or FAX. > >Sincerely, >Lorn H.

I did a >complete external inspection. No problems were found. > >When sitting in the cockpit, I moved the stick control left and right >with no binding. I then moved the stick back and forth and felt a >slight grating at the far back extension of the control. I tried the >back and forth motion several times with different trim settings. I >thought that this slight binding may have been what I interpreted as >a stop when I landed in November. > >Next I fired up the engine and taxied to the runup area. While going >through the checklist, I tried to move the stick back and forth. The >stick hit a complete stop 3 to 4 inches before the aft most position. >I tried all trim settings with both sticks, but nothing helped. There >was a complete loss of the last 3 to 4 inches of elevator travel. I >was elated. It wasn't me. I had not forgotten how to land. I taxied >back to show the mechanics. > >When the mechanics came out to inspect the plane, everything worked >fine. What could the problem be? Could it have something to do with >the prop wash? We had to find out. This was a really serious and >dangerous problem. > >I had one of the mechanics sit in the right seat and work the stick. >As soon as I sat down, we lost the last 3 to 4 inches of stick >motion. At last, I thought, the seat must be broken and be >interfering with the controls. > >I got out and we removed the seat cushions. The fiberglass seat >bottom had not been inserted in the forward lip. By laying the seat >bottom on the lip rather than inserting it, the seat bottom was >allowed to slip forward 1 to 2 inches. The forward motion of the seat >bottom and hence the hole that the stick moves through caused the >stick to stop 3 to 4 inches before its full back position. > >I am writing this long letter to let other LNC2 owners know that the >seat bottom installation is very important. If anyone else has >inspected your plane, make sure that the seat is seated correctly. > > From the accident report above, you will notice that I could not fly >below 105 mph. Had the seat slipped any further, I may not have been >able to fly under 200. This could be the recipe for catastrophe. > >I have since flown the plane twice. Great landings with my new Ong's >Debongers. I did notice a slight fishtail when I first touch down. >Any comments on this? I will report further on the Debongers in >another issue. > >Good luck on building and flying. > >Sincerely, >Lorn H.
