Since I pick up my fuselage kit at Zenith next month, I thought I'd call Todd's Canopies yesterday to see what the lead time was for ordering a 601XL canopy. Todd answered the phone promptly, was very polite and helpful, and mentioned he will soon be supplying his canopies directly to Zenith and that the 601XL model is no longer available directly from him. He also apparently built a couple new designs for Zenith that they are evaluating for incorporation into the kit. He described the prototype as slightly longer overall and potentially two piece, i.e., the larger portion may hinge forward with a portion remaining aft incorporating a roll bar. When I make my trip to Mexico, MI in a couple weeks, I hope to get some information from Zenith about the timeframe for availability.

Not a dumb question Andrew, and you don't have to be embarrassed as we've all made minor mistakes. The hazard is not correcting them when we see them. I'd recommend you make adjustments that allow you to lay a yardstick or such across the ribs to get them aligned. It may only take drilling out the rivets, or clamping and drilling for the next size rivet, or making the rib over. This would be a good time to learn the art of replacing a bad part with one built from scratch. It'll save you a lot of money. The misalignment would probably be easily seen, so I'd go for the fix and hold onto your sense of what's right. Go for it.

From: "ashontz" I believe the rule is, anything bolt that's subject to torsional forces, like a pivot point, should have a castelle nut and cotter pin. Additionally, any locking nut application (not a cotter pin nut) that's in a high heat area, like the engine compartment, should use a fully metal lock nut, not a nylon insert for the locking effect. Of course, you should never reuse a locknut of either type. You're probably supposed to always use a new cotter pin too whenever a castelle nut is reinstalled.

It took about 2 weeks as advertised and it arrived in great shape. If he is going to be the Zenith supplier and no longer shipping direct to customers, I would order right now. His price was a little over half of what Zenith currently charges. I ordered the hardware portion of the canopy kit from Zenith and Todd's canopy fits it just fine, so far. The canopy I received from Todd was longer and higher than those I have seen on other finished 601XL's. Maybe this is the 'prototype' size you mentioned. I only trimmed it a little bit, leaving it on the large side. I hope to be finished with my canopy install in the next week or so. I am looking forward to information on the new two-piece design you said Todd mentioned. It would be nice if it was easily retrofittable to current 601's in case I decided to change sometime down the road. Good Luck, -------- David Gallagher 601 XL, working on final assembly.

When you sell kits, you entertain the idea that there are at least a percentage of the builders that couldn't or wouldn't build or fly to recommended guidelines. The prospect of a defect which makes it easy to foul the strength of the lower spar caps and surrounding wing structure is a possibility. I'd still contend that people that stay with the plans and and build strictly to the drawings are never going to see a problem. If you read the ntsb records for the 601 of recent, you'd probably come to the same conclusion.

It's one thing to plug and chug on a computer then throw >sandbags on a structure and call it sound. I'll not comment on what Zenith should or should not do. I want to address the issue of an independent engineering analysis of the 601XL wing that was raised some months ago, I believe following the Barcelona accident. Andy Shontz had started a thread asking for Zenith-Listers to respond if they would be willing to financially support an engineering analysis of the 601XL wing. Andy was not able to pursue the analysis, so I asked a former colleague, Don Rabern (who is now Dean of Engineering at Embry-Riddle Aeronautical Univerisity, Prescott, Arizona), if he could recommend someone who would be both capable of and interested in doing the analysis. Don responded with two names. After a few days of working our way through their spam filters, I have established contact with Mark Sensmeier, an Assistant Professor of Engineering with a B.S. in Aeronautical and Astronautical Engineering from Purdue University and a Ph.D. in Engineering Mechanics from Virginia Polytechnic Institute and State University. He is interested and we are planning to talk later this week about the problem. Assuming that our talks are productive, my plan is to approach the List again to solicit real cash (as opposed to expressions of interest) so that we can develop some sort of contract for the work to be done and the amount to be paid. Don suggested that it might be "great fun" to test an actual wing in their structures lab. With a bit of luck, I may finish my right wing in an appropriate time frame, and I *might* be willing to have them do some (non-destructive) testing on my wing. We will have to wait and see if that looks to be worthwhile. I would envision establishing a bank account for something like the "Zenith Builders Analysis Group" to handle the money. There are two other 601 builders in my neighborhood, one of whom could provide a second signature on all checks and/or withdrawals to provide some fiscal discipline for the "Group." I am posting this as a progress report. Comments and/or suggestions are welcome. I would be happy to send to any interested person my informational emails to Mark .

NTSB Identification: NYC08FA158 14 CFR Part 91: General Aviation Accident occurred Monday, April 07, 2008 in Polk City, FL Aircraft: Chech Aircraft Works SPOL SRO CH 601 XL RTF, registration: N357DT Injuries: 1 Fatal. This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. On April 7, 2008 about 1700 eastern daylight time, a Czech Aircraft Works SPOL SRO CH 601 XL RTF, N357DT, was substantially damaged when it impacted trees and terrain following an uncontrolled descent near Polk City, Florida. The certificated private pilot/owner was fatally injured. Visual meteorological conditions prevailed, and no flight plan was filed for the flight which departed Williston Municipal Airport (X60), Williston, Florida and was destined for Lakeland Linder Regional Airport (LAL), Lakeland, Florida. The personal flight was conducted under 14 Code of Federal Regulations Part 91. According to friend of the accident pilot, they both shared a hangar at Lumpkin County Airport (9A0) in Dahlonega, Georgia, and they planned to fly their respective airplanes to an air show in Lakeland, Florida. The accident pilot departed Dahlonega about 1240, and the friend departed about at 1300. During the flight the friend passed the accident pilot, landed at Williston Airport for a planned fuel stop, and subsequently departed. He last spoke to the accident pilot about 1500, as the accident pilot approached Williston. The accident pilot planned to land about 1530, and stated that his airplane was "running fine." Review of fuel receipts revealed that the pilot purchased fuel in Williston at 1607. About 1700, a witness, located about 1/2-mile southeast of the accident site, observed the accident airplane as it approached him from the north. He noted that the airplane was noticeably lower than other airplanes that generally flew in the area, and that it was in a 3- to 5-degree left bank. The airplane then banked right, about the same magnitude, before it returned level for a moment. About 1 to 3 seconds later, the airplane banked to the left and to the right, significantly steeper than during the previous banks. After banking back to level, the airplane yawed right, and the "right wing folded up." The airplane banked right and the left wing "went up" just before the airplane entered a nose dive. The witness described that the wings of the airplane looked perpendicular to their normal position, and that the engine sound changed, as the airplane descended downward. The witness heard the sound of the engine pitch change to the point where it sounded like the engine "over sped" as the airplane descended. He lost sight of the airplane shortly thereafter as it descended behind a building. Another witness, located about 1/3-mile west of the accident site, stated that he heard a "pop" and that when he looked up he saw the accident airplane. He described that the "right wing was folded back and to the side," and that the accident airplane was spinning as it descended. About 8 to 10 seconds later he heard the sounds of an impact. The pilot held a private pilot certificate with a rating for airplane single engine land. His most recent Federal Aviation Administration (FAA) second class medical certificate was issued on February 29, 1980. Examination of the pilot's logbook revealed that he had accumulated 514 total hours of flight experience, 71 hours of which were in the accident airplane make and model. According to the pilot's friend, the pilot originally obtained a pilot certificate in the 1970's, and had recently began flying again after purchasing the accident airplane in October 2007. The accident airplane was manufactured in 2005 and was classified by the FAA as a Special Light Sport Aircraft. According to maintenance records, the airplane was factory test flown on June 16, 2005. The airplane's most recent annual conditional inspection was completed on September 1, 2007. At the time of the inspection, the airplane had accumulated 142 total hours of operation. The weather conditions reported at LAL, located about 17 miles southwest of the accident site, at 1658, included winds from 030 degrees at 4 knots, 15 statute miles visibility, scattered clouds at 3,000 feet, broken clouds at 25,000 feet, a temperature of 27 degrees Celsius (C), a dewpoint of 16 degrees C, and an altimeter setting of 29.90 inches of mercury. The airplane came to rest in a heavily wooded area and exhibited various degrees of damage throughout. The trees in and around the accident site had been removed to facilitate access to the wreckage. Examination of photographs taken by first responders revealed that the airplane was lodged in the ground at an approximate 45-degree angle, and that the fuselage was positioned in an approximate 45-degree left bank. The left wing was bent upward (in the positive direction) at the wing root approximately 90 degrees, with the remainder wrapped around the top of the airplane. The right wing was bent 90 degrees forward about the mid-span point, and was wrapped around a 4-inch diameter tree. Initial examination of the wreckage revealed that the horizontal stabilizer and rudder were separated from their respective attach points, but remained co-located with the wreckage. Detailed examination of the left wing revealed that the lower main wing spar cap was fractured at the wing root. Portions of the left wing spar were retained for further examination. The remainder of the main wing spar, which extended through the fuselage and the right wing, was bent but remained largely intact. Control cable continuity was confirmed from the rudder pedals to the rudder horn attachment points. Elevator control continuity was confirmed from the cockpit to the elevator control horn attachment point, which had been disconnected by first responders during recovery. The electrically actuated elevator trim was in a neutral position. Continuity of the aileron control cables was confirmed from the cockpit to both ailerons. The electrically actuated aileron trim was positioned at the tab trailing edge down limit. Disassembly of the aileron trim servo revealed that the mechanism was positioned aft, in contact with a forward-facing micro-switch. The aileron trim servo, switch, and indicator were retained for further examination. Both wing flaps were dislodged from the stowed position, and their actuators were broken. The engine was located at the forward portion of the wreckage, and was buried in 6-foot deep crater. All three composite propeller blades were separated near the propeller hub. A portion of one blade was found outside and adjacent to the crater, while the remainder of the blades were found within the crater. Crankshaft, gearbox, and valve train continuity were confirmed from the propeller hub to the aft portion of the engine. The propeller hub could only be rotated through 180 degrees of motion, and valve motion was observed on all but the number 4 cylinder intake valve. All eight spark plug electrodes were intact and light gray in color. Examination of the oil filter revealed no evidence of any visible metal particles. Both fuel tanks were ruptured and absent of fuel. There was a strong odor of fuel at the scene, and fuel was observed leaking from several fuel lines during the recovery process. The fuel selector knob was observed in the "left" position.

But not to the aircraft , I currently own a 601 xl tail dragger which i built and have 100 hrs on , this was a czaw 49% kit , and has some minor differences , ie composite main gear etc , so structurally i believe the same as the US version , also built and owned a ch601 ul again with around 140 hrs . Have overseen 6 or more kit builds . as an engineer , for more years than i care to remember , i read these accident reports with interest , especially when my backside is at risk . The eye witness reports indicate some rolling and yawing before the fold , the report says that the spars were in tact but bent , but what about the rear attach point ? have any tests been done sand bags and all , to see what happens when you loose that rear fixing , the mechanics of what happens with a non vertical leaning main-spar are quite frightening , then couple that to the xl flap drive arrangement . for example - you loose the rear attach, the wing will go negative, that then will force the flap down , and thus aggravate the problem . As an owner and builder of this sporty design , with a close friend which has just spent his hard earned wages on a new xl kit, I now feel very strongly that all avenues of failure must be explored . pilot error will always be with us , but structural failure is a real concern .

I want to address the issue of an independent engineering analysis of the 601XL wing that was raised some months ago, I believe following the Barcelona accident. Andy Shontz had started a thread asking for Zenith-Listers to respond if they would be willing to financially support an engineering analysis of the 601XL wing. Andy was not able to pursue the analysis, so I asked a former colleague, Don Rabern (who is now Dean of Engineering at Embry-Riddle Aeronautical Univerisity, Prescott, Arizona), if he could recommend someone who would be both capable of and interested in doing the analysis. Don responded with two names. After a few days of working our way through their spam filters, I have established contact with Mark Sensmeier, an Assistant Professor of Engineering with a B.S. in Aeronautical and Astronautical Engineering from Purdue University and a Ph.D. in Engineering Mechanics from Virginia Polytechnic Institute and State University. He is interested and we are planning to talk later this week about the problem. Assuming that our talks are productive, my plan is to approach the List again to solicit real cash (as opposed to expressions of interest) so that we can develop some sort of contract for the work to be done and the amount to be paid. Don suggested that it might be "great fun" to test an actual wing in their structures lab. With a bit of luck, I may finish my right wing in an appropriate time frame, and I *might* be willing to have them do some (non-destructive) testing on my wing. We will have to wait and see if that looks to be worthwhile. I would envision establishing a bank account for something like the "Zenith Builders Analysis Group" to handle the money.

I think all of you should read some of these reports. Either the NTSB is incompetent, or just plain disinterested. They hardly ever discover the cause of light aircraft mishaps nor do they share pertinent data in those reports.

What they say (news men) in their favor is that the news guys only writes what the witness (most of the time with cero aviation knowlege) "told him", they keep the tape as proof, plus they mght add a little "imagination", "personal research" and "aviation related words he thinks he knows" and the final result is really strange, sometimes even "comical" for us pilots, that have a liitle bit or real aviation knowledge. Remember also that aviation accidents and artist divorces Sells newspapers, this sells comercial spotts, etc :-) :-) So they need to make the report "Interesting", for say the least. What we are all doing right now Here in the List, is waiting for the official results, given that NON ONE OF US in the list, have the credentials or know facts first hand, to even THINK about the enginering design of the airplane or less about the experience or knowledge or medical condition of the pilot in the moment of the accident.

I know nothing for a fact!!!! 1. In Chris's letter he acknowleged that some of the 601's had experienced an (in-flight breakup)(Pilot or builder abuse or error) 2. There are 2 witness that said that the RIGHT wing folded. 3. The NSTB report stated that the right wing was bent at about the midpoint, (also wraped around a tree) Midpoint was about the place at least one other 601 wing failed. 4. The left wing "going up would be consistant with a lack of a right wing. and the other damage may have been caused by the impact. 5. The pilots shallow banks, then steeper banks would be consistent with a pilot trying to figure out a problem with the airplanes controllability. 6. I sure would hope that the NSTB or someone in the know would quickly point to the failure sequence of events as to what failed first to allow the right wing to fold so it might be addressed.

First there is no Official Confirmation about a wing failure in this particular accident For reasons some people such as yourself can't understand, some of us have professional and/or personal reasons not plaster our name on the internet. I'm not a troll and I don't work in the airplane business. I'm not an agent provocateur. I am a 701 builder bewildered by the lackadaisical attitude on this subject both by the designer and some of the builders. I am a PPL and have completed a previous homebuilt. I have no concern about the 601HD/S or 701. Now just what kind of "Official Confirmation" do you need Gary? Just what exactly? What kind of letterhead? What internet domain? Who needs to knock on your door? How many death certificates? Just what kind of evidence would convince you? I'm not trying to kid myself and others that the half-finished XL in my garage is safe because--I don't have one. A few months ago several Zenith builders said "let's wait for the results." In the mean time, it APPEARS that we have lost another soul in an accident that may have been preventable.

Regarding holding the money and/or finding an engineer (if the other fellow doesn't work out), I might suggest simply working through a local EAA chapter or calling HQ for advisement. Of course calling Zenith and working through them would be best...would give the AE a running start to have such access. Frankly, I would be surprised that a faculty academic would take on this project for money. I would assume that the respective university would have to grant approval for the project, which might be troublesome politically etc. On the other hand, doing this kind of analysis really gets some people going.

I'm truly sorry for your loss, and especially the circumstances surrounding it. I'm sure you're more anxious to get the results of the NTSB investigation into it than any of the rest of us. > Question: Was the Czech Aircraft works aircraft assembled in Georgia? No. Czech Aircraft Works was, as the name implies, a Czech company that built the CH601XL aircraft in the Czech Republic under license from Zenair. -- Jay Maynard, K5ZC http://www.conmicro.com http://jmaynard.livejournal.com http://www.tronguy.net Fairmont, MN (FRM) (Yes, that's me!)

Sorry for this posts, yes, we all are waiting for oficial report, I will not post anything about this matter, Good or Bad, until a serious report is here. Not my type of posts, probably a result of the normal pressure in everyday work, well hope you all forgive me... I will try not to happen anymore. Saludos Gary Gower Flying from Chapala.

First there is no Official Confirmation about a wing failure in this particular accident, in the first place. Second, We (all over the world) that are pilots (or at least we can control an airplane fairly acceptable), just need to read the newspapers or watch the news in the TV of any accident aviation related, to see the most far from reality facts there. Some times are not really "bad intention" from the reporter. What they say (news men) in their favor is that the news guys only writes what the witness (most of the time with cero aviation knowlege) "told him", they keep the tape as proof, plus they mght add a little "imagination", "personal research" and "aviation related words he thinks he knows" and the final result is really strange, sometimes even "comical" for us pilots, that have a liitle bit or real aviation knowledge. Remember also that aviation accidents and artist divorces Sells newspapers, this sells comercial spotts, etc :-) :-) So they need to make the report "Interesting", for say the least. What we are all doing right now Here in the List, is waiting for the official results, given that NON ONE OF US in the list, have the credentials or know facts first hand, to even THINK about the enginering design of the airplane or less about the experience or knowledge or medical condition of the pilot in the moment of the accident. SIMPLY because we were not there or know nothing about this. Acting like you are now can be embaracing, because in my city, (talking without facts) is only admited to ladies in the market or at the laundry shop... I will beg you to wait a little, like all of us to read from the Real Source before having to say Im Sorry, my bad.... Also we PILOTS (if your are one(?) need to show respect for other pilots and airplane designers, this is first of all not talking as truth what YOU are not sure is fact, mostly if this is doing harm to them, in any way.

I don't know anything about Czech, but insofar as they previously manufactured aircraft under agreement with Zenith, I would ASSuME that Czech could manufacture an aircraft with at least the competency of the average homebuilder.
