This was at Nairobi (Kenya) Wilson airport, where the plane is based, and coming in from a 3 hour flight. On touchdown, I realised a problem as the wing went down, and opened up the throttle, took off again. Then called the tower, did a low pass, the engineer confirmed that the 'leg was not there'; the following landing aircraft reported 'debris on the runway... my outrigger!'. After circling a bit, the engineer lined up about 15 people along the runway to catch the wing on landing. On landing, all these guys ran very fast to catch it, but actually the plane stayed level, as the C of G (with me in pilots seat, no pax) was within the triangle of the maingear, tailwheel and left hand outrigger. Inspection showed the starboard outrigger had snapped off right at the holder, or whatever its is called. I now inspect the outrigger legs at this point, as part of pre-flight. Best to all and happy flying.

Very sorry to hear about your prop strike, Kevin. Unfortunately, the following comment on the forum is not correct, even if you have the slipper clutch: At least with the Rotax if there is no runout problem on the prop flange you can just bolt up a new set of blades and go again...not sure what airmaster advises though. Attached please find a Rotax Service Letter addressing prop strikes, and a relevant page in the most recent version of the Line Maintenance Manual re. inspections, all of which shall be carried out by authorized service personnel. In addition to this, the Scandinavian repair center for Rotax advises that the roller bearing for the propeller shaft, mounted in the engine crank case, shall be replaced. This information may come as a surprise to some, as it did to me when I first heard about it an authorized Rotax maintenance course. I held the fairly common misconception that if you have the slipper clutch, just replace the prop. NOT SO! The advantage, though, is that with slipper clutch the probability of damage to the gear box or the crankshaft is significantly reduced, but not eliminated. Thorough inspection according to the Rotax SL/Maintenance manual is mandatory, however. A Katana with 912S with slipper clutch here in Norway recently had a prop strike with engine damage as a result - in some instances, the damage occurs before the clutch slips, the repair center told me. Prop strike at idle RPM is sometimes worse than at high RPM, they added.

Since the starboard wing was not fitted, quite some weight hit my wife's leg. She and the leg did not like that. Her leg however did not break. I reported that back to the factory, and on their request sent the broken ends to check. Never heard anything about a reason though. Some reasoning led to the conclusion that the nylon can dry out if the air humidity is very low on average.

It seems this could happen to all of us monowheel drivers and I am very concerned about that happening to me. The consequences could even be more serious than a broken prop, especially on a narrow mountain or farm strip bordered by fences, ditches or trees. Relying on the random quality of a piece of nylon is not satisfying. Has any one engineered a replacement rod made of other material such as glassfiber or metal ? Some motorgliders are using spring steel rods successfully. It seems to me that the possible failure of those materials under extreme load, fatigue or aging would be a lot more predictable than with the supplied nylon outriggers.

Gliders after all always land without any, just keeping the plane level & pointing in roughly the right direction until it stops, when it gently subsides on to one or other wingtip. If anything the loss of an outrigger should help to keep that wing up as the other will be slightly weighed down. As we are as often as not on one or other outrigger wheel during the take off & landing run, dealing with the very small amount of drag on a solitary outrigger shouldn't be too difficult. I wouldn't look for alternatives, just perhaps think of taking a spare if embarking on a long tour.

All seems well with exception of rotax tacho. Advancing throttle from 'rough running' to just smooth, the tacho jumps from <2000rpm to 4000rpm - numbers which I just don't believe. Anyone got any thoughts? Unfortunately the rest of our engine instruments are a BMA EFIS1 which doesn't easily support an alternative tacho for the rotax.

Not good those Rotax tachos, we used a Grand Rapids EMI which was perfect.
