Sent by: owner-kis-list-server@matronics.com Fellow KIS owners, Now that the formalities have been dealt with, I can share with you that I had the misfortune to be involved in a hapless accident on the ground last week. I would like to share my experience with other KIS TR-1 owners; perhaps it can help prevent a similar incident. A copy of section 16 of the aircraft accident reporting form below conveys the essential information. ------------------------------------------------------------------------------ 16 YOUR ASSESSMENT OF THE CAUSE My right foot slipped off the starboard rudder pedal at crucial moment whilst straightening out the steering nose wheel upon commencing the second stage/leg of a taxiing manoeuvre intended to take me away from the disembarkation area. Despite a tightly strapped full harness, the unexpected forward lurch of right hip and shoulder resulted in an inadvertent knock-on to the throttle, increasing the engine rpm setting substantially beyond my self-imposed limit for taxiing on tarmac. To fill up the mug of misfortune, the uppers of my shoe heel caught on the rear edge of the starboard pedal or brake hinge upon pull-back, effectively locking in a turn to port side whilst also rendering me incapable of braking and/or steering effectively. Three seconds later, with foot still stuck, it was all over with two aircraft substantially damaged and probably destinied to be written off. Safety factors: (specifically relevant to other KIS TR-1 owners) 1) Rudder pedals should be aligned squarely with pilots hips, not offset at an angle inboard. The vertical angle of rudder and brake pedal should allow full surface contact with pilots foot at all times and pedal surfaces should have high friction coefficient. 2) The release mechanism on a vernier throttle should be operated by pulling action on a bell shaped slider or finger hook at the rear of the throttle knob (as on automatic gear shift levers of many vehicles) so as to automatically enable reduction in power when pilot pulls on the throttle control mechanism from the rear. Activating the release mechanism by depressing a knob from the front allows for inadvertent escalation in power by knock-on at front of the throttle control, whereas it does not facilitate reduction in power when pilot tries to pull/tug it the throttle outwards in an emergency situation. ------------------------------------------------------------------------------ The accident resulted in the destruction of two aircraft, mine and another which was parked. Fortunately, I did adhere to my rule not to start up or taxi when there are people moving around airside and by Gods grace I escaped with nothing but a headache and a few scratches. Please take the time to critically re-inspect your rudder pedal configuration - I suspect many of you have the same smooth and rather skimpy pedals which my aircraft is fitted with. If it is at all possible that your rudder pedals could enable/allow the same accident to happen do not postpone getting proper pedals fitted. I did, and it cost me dearly. Having insured the hull only for the amount I paid for it, it seems that it will be more cost effective for the insurance company to scrap it. So it seems that I may soon be looking for another KIS TR-1 to buy. These things do happen in the blink of an eye, so please watch your step (on the pedals and everywhere).

I would like to share my experience with other KIS TR-1 owners; perhaps it can help prevent a similar incident. A copy of section 16 of the aircraft accident reporting form below conveys the essential information. ------------------------------------------------------------------------- ----- 16 YOUR ASSESSMENT OF THE CAUSE My right foot slipped off the starboard rudder pedal at crucial moment whilst straightening out the steering nose wheel upon commencing the second stage/leg of a taxiing manoeuvre intended to take me away from the disembarkation area. Despite a tightly strapped full harness, the unexpected forward lurch of right hip and shoulder resulted in an inadvertent knock-on to the throttle, increasing the engine rpm setting substantially beyond my self-imposed limit for taxiing on tarmac. To fill up the mug of misfortune, the uppers of my shoe heel caught on the rear edge of the starboard pedal or brake hinge upon pull-back, effectively locking in a turn to port side whilst also rendering me incapable of braking and/or steering effectively. Three seconds later, with foot still stuck, it was all over with two aircraft substantially damaged and probably destinied to be written off. Safety factors: (specifically relevant to other KIS TR-1 owners) 1) Rudder pedals should be aligned squarely with pilot=C3=A2=82=AC=84=A2s hips, not offset at an angle inboard. The vertical angle of rudder and brake pedal should allow full surface contact with pilot=C3=A2=82=AC=84=A2s foot at all times and pedal surfaces should have high friction coefficient. 2) The release mechanism on a vernier throttle should be operated by pulling action on a bell shaped slider or finger hook at the rear of the throttle knob (as on automatic gear shift levers of many vehicles) so as to automatically enable reduction in power when pilot pulls on the throttle control mechanism from the rear. Activating the release mechanism by depressing a knob from the front allows for inadvertent escalation in power by knock-on at front of the throttle control, whereas it does not facilitate reduction in power when pilot tries to pull/tug it the throttle outwards in an emergency situation. ------------------------------------------------------------------------- ----- The accident resulted in the destruction of two aircraft, mine and another which was parked.

Hi Alfred, Sorry to hear about your accident but glad to hear no one was hurt! Please add me to the camp that thinks a vernier on the throttle is a bad idea. Reducing throttle should not require 2 actions. Some builders have cut off the inward turned outboard rudder pedal tube and rewelded it so that it is outboard pointing. This allows the outboard rudder pedal to farther outboard so that they can be centered. This will increase stress on the part so really this whole tube assembly should be rebuilt or at least reinforced.

Imagine you just had a prop mounted to a shaft at the front of a glider. As you are gliding the prop will be spinning. Making it spin of course requires some energy. This is where the drag of the prop comes from. Just to overcome this prop drag you need to put some power into the prop. It may also be useful to think about autogyros when thinking about prop disk drag. So, depending on many factors, a larger prop is not always better. In general a larger prop is better at lower speed and a smaller prop is better at higher speed.

Such propeller will also function optimally at 2300 rpm at 7500 feet for cruising. According to Lonnie the P-tip with 67 inch pitch will flex to such an extent under load that it will effectively present a 63 inch pitch during take-off/climb. > >By the way, I found it puzzling that the Prince website talks about the propeller diameter being a factor in the flat plate drag of the aircraft. Because the propeller produces netto thrust which increases quadratically with diameter that statement initially failed to compute in my mind. On the other hand however, propeller parasitic losses do increase with diameter and rpm - so perhaps they are implicitly lumping propeller parasitic losses into the overall zero lift drag coefficient for the aircraft (and thereby also into the flat plate area). I have not encountered such point of view before, but it is the only interpretation which makes sense to me. One has to be very careful with that approach though, because the airspeed multiplier by which drag converts into power is of course completely different for the propeller and airframe. > >It remains to obtain torque and thrust curves for a 67 x 67 propeller from Lonnie Prince and his team to confirm that my postulated propeller blade model is not too optimistic in terms of performance - nor too conservative. > >Kind regards, > Alfred > >-------- >_________________________________________ > > >Read this topic online here: > >http://forums.matronics.com/viewtopic.php?p=332343#332343 > > ________________________________ Message 11 ____________________________________ Time: 06:33:16 PM PST US Subject: KIS-List: Re: Are your rudder pedals safe? From: "BlueSkyFlier" Thank you everyone for commiserations expressed. I am of course thoroughly gutted and miserable about the whole debacle, but spunk is nonetheless slowly seeping back into the spine. Tomorrow we shall take a serious look at the possibility of repairing the plane. So very glad to hear that you are on the mend Rich! You are right, it does take a lot to total her. You should see the other guy and he was all metal. Suffice to say I now have a greatly increased respect and appreciation for the strength of a composite plane. Since the engine will need a shock-load inspection anyway Ill have it zero-timed in case we decide to repair her. The engine mounting and firewall seemed unperturbed on initial inspection. For the airframe we have two primary challenges (unless others come to light tomorrow). 1) The LAA (PFA) here may argue that the spar was stressed to some extent to prove the integrity of the wing is a tricky business at the best of times. Hence Im all the more glad to see you back on the forum Rich. Your opinion will carry considerable clout with the LAA. Since the wing tanks are not leaking I am thinking it cant be too bad, but what do I know? :o) 2) I shall be in need of a new windscreen because the chewed-up elevator of the Cessna came slicing through mine. (Im growing a beard now as that was as close a shave as I want to have for quite some time.) The port hatch is complete unhinged hence my headache and the instrument panel is dislodged, but both those should fairly straightforward to fix. With the collective knowledge and experience of everyone on this forum decisions regarding the best way forward will surely be greatly facilitated. For instance, a few weeks before the accident I spoke to a KIS owner here who described his deregistered KIS as bent. Quite likely that parts of his plane could be re-usable and Ill follow that up. (He is now building a Glastar.) John (Jackson), I would very much like to discuss the options you mentioned. Could you please send your contact details via direct email? And thank you also to Keith (Miller) for the tip about fixing the alignment of the rudder pedals. Given opportunity, I shall implement that together with OCs pedal mod. In case we decide to investigate the repair options further after tomorrows inspection I shall open a new thread for that. Thanks again and best regards to all. - Alfred -------- _________________________________________ Read this topic online here: http://forums.matronics.com/viewtopic.php?p=332579#332579 ________________________________ Message 12 ____________________________________ Time: 07:01:50 PM PST US Subject: KIS-List: Re: KIS TR-1 Propeller From: "BlueSkyFlier" Thanks Mark, so understood. That's why I said the prop has 'netto' thrust with the drag you refer to already subsumed/eliminated when thrust is produced by the prop. Different of course during deceleration, dive, idle and (god forbid) engine failure.
