Magni M 24 "Orion" Gyroplanes

[Waddles]

Gidday All,We have received advice of a Mandatory Directive issued by the UK CAA in respect of an in-flight failure of the rudder control system on this type. There are just two of these types either in country or enroute. Magni Australia is working with the factory to determine if these aircraft are affected.I will attach a copy of the directive for your information.Regards,Allan Wardill.

Gidday Members,Further to my post above, I am able to confirm that following contact with the factory by Magni Australia, manufacturers serial numbers confirm that no Australian gyroplane is affected by this Directive.I thank Magni and their Australian distributor for their rapid response to my query.Regards,Allan Wardill

Thanks AllanI found the following comment very interesting."Failure of the rudder peddal mounting block may result in loss of control of the gyroplane, and loss of the gyroplane"The loss of control of a rudder or rudders should never cause the loss of control or loss of a gyroplane EVER. It should cause loss of yaw control only. I am yet to fly a Magni, let alone an M24, but does this mean you need to activley fly the rudder in the new M24????Cheers SamL..................

Hi Sam,To put Allens comment into perspective "it may cause the loss of gyro"which it may do.However this is the language of cover my ass while I"m in a public position for example. Kym.

Sam, you got to remember that some people cant even push a wheel barrow without getting into trouble !

Didn"t a RAF come to grief when it"s rudder cable failed a while back

[asra]

Both Kym & BrianI totally understand and accept this as possible ass covering on Magni behalf. I guess were I"am coming from is the fact that there are many machines out there where the active use of rudder is a requirement of safe every day flight. This is totally unacceptable in my opinion and I would refuse to sign off or allow such a machine to fly. A classic example is a RAF 2000 fitted with doors. All machines should be totally stable in yaw regardless of flying conditions, on climb, on decent, power on or off.My 2 bob

[tonydenton]

sam how do you test it [ actually test it] to sign off. do you disconnect the cables in flight ?

Sink the boot into it with ya legs crossed

Hi TonyOn take off no rudder is required.On landing (nil wind, or head wind) no rudder is required.Straight & level flight no rudder is required.Turns, no rudder is required.Glide decent (no power) no rudder is required.In a small open frame machine this is simple to acheive. In a fully enclosed machine this does create a challenge during design/re-designing & testing stages. Once acheived the benefits are many, and flying becomes as simple as flying FW"s.Regards SamL..................

So what if you go by that standard Sam, that would mean ever helicopter ever made would be grounded.Near ever F/w would be grounded.If this is the case i guess the Kuza doesnt even have a rudder then huh??That is one of the most rediculas comments i ever read by you.......The rudders are there to be used otherwise they wouldnt be there in the first place???????? What am i missing?The rudder is there to correct for machine yaw during cross wind landings, take offs, or to acheive very tight turns. They should not be used to correct for a machines inability to self correct in yaw. If this is the case then the machines CofG and CofP are possibly to close. Also if the machine requires active use of rudder to stop it swapping ends then it is out right criminal. As what would happen if power was lost? would the rudder still retain enough authority (without the assistance of prop wash) to allow you to correct?This is again just my rediculas opinion Bonesy :Regards SamL...................

Ahhhhh! So you are getting out of training.No point in sending anyone your way then eh?

[aussie_paul]

IMHO I don"t

[birdy]

Nun will fly true in all siutations PB [ coz of the "p" facter], but they should still be controlable, and landable.

Birdy, my post was in response to Sam"s comments of, Hi TonyOn take off no rudder is required.On landing (nil wind, or head wind) no rudder is required.Straight & level flight no rudder is required.Turns, no rudder is required.Glide decent (no power) no rudder is required.Aussie Paul.
