Rudder pedal AN131008-1-1

[old man emu]

This AN requires that before the next flight, steps are taken to disable to fore/aft adjustment of the rudder pedal shafts. THe problem seems to be that if the pedals are adjusted all the way out, there can be interference with the movement of the rudder controls.

 

There is a simpe fix for this.

 

Firstly get hold of a right angled drill attachment.

 

Get four AN3-10A bolts and four MS21044N3 locknuts.

 

Position the rudder pedal shafts so that they are in about the middle of their fore/aft travel.

 

Drill horizontal holes through the shafts and their collars.

 

Fit the AN3-10A bolt through each hole and secure with a locknut.

 

Repeat for the right hand pedal set.

 

This job should take less than half an hour to do. Don't forget to vacuum the cabin floor to pick up the metal flakes.

 

Note

 

The need for urgency for this mod seems to depend on the number of different pilots who fly the aircraft, and their heights. If you are the only pilot, and have medium to long legs, you are unlikely to encounter the problem.

 

If many people of shorter stature fly the aircraft, it needs to be done straight away. These people also need to obtain an extra seat cushion.

Went to the Jabiru website...no sign of an SB about this. The Jabiru website is my oracle for SBs etc re the Jabiru.

 

What models of Jabiru are involved? What was the original problem that gave rise to this? Where is this documented (citation please) Who is the publishing authority? Full text of AN (if possible) would be appreciated. Did this arise from Australian Jabiru operations or what?

 

I assume this applies to both kit-built and factory-built Jabirus. If this is the case, I find it extraordinary that a certificated aircraft could have such a design mis-feature as rudder-pedal interference when adjusted fully out ever get through certification. Still...there was that early DC-10 cargo-door problem, so certification doesn't always find everything.

 

Basically, more information please.

The SB/AD is relevant for models with the adjustable pedals.

 

The problem arises from pilots / students who don't have their heals on the floor when pressing the pedals. If you press 'down' rather than 'forward' you'll come across this problem.

Yea, the problem is the arc of travel, when you push one side right in the other side comes forward and travels on an arc downwards towards the floor.. and like brentc said, if you push down on the peddal it does diddly squat.. its a real gotya.. and its got some experianced guys.. We comlained to jabiru over a year ago about this problem when the chief went for an off road trip across a taxiway and over a ditch after it got him.. this dude has 20000 hrs plus.. can't believe its just getting attention now..

Did you chance to look at the "Aircraft AD's & AN's List - Jabiru Aircraft & Engines" thread on this very forum?

 

That's a good place for oracles to stir over the entrails.

Doesn't your Chief always come back to base via a cross country route?
