Hi Rob,
A question The engine mount gusetts .... is there any drawings for them ?? Best regards Ian Williams Auckland From: Rob Thompson [mailto:[email protected]] Sent: Tuesday, 25 August 2009 9:38 a.m. To: [email protected] Subject: Re: [DOG mailing list] New subscriber from the UK Hi Dave, I think the major difference between Mk 1 and 2 is the aileron system. The earlier models had spring loaded ailerons as they didn't tend to naturally return to the middle. These ones tend to be a little jerky on the ailerons and feel strange to start with. You get used to them however. I do find them more difficult to teach basic controls to students as there is not the same feel in the system as you would be used to. Watch for .. Old style engine mounts - there should be gussets around the mount bolt holes or they crack - engine out to fix. Elevator bell horn - internal bolt holes elongate and become sloppy - double skin fibreglass repair to fix. Prop change bearings don't contact prop brake plate together - very common and probably responsible for the studs occasionally breaking. Undercarriage rod end bearings not replaced - needs a hole cut in the cockpit floor to the aft of the pedals on both sides. Elevator rod end bearing not changed - the originals are not acceptable any more Cracking on undercarriage leg - there will always be slight cracking in the filler / paint but make sure they aren't deeper. Corrosion in aileron piano hinge - rivets start to pop out Seized roller bearings inside wing aileron circuit - need to cut heaps of holes to fix. Main pins meet AD - some needed to be replaced. Airbrakes can jam - try this... have someone try to open the brakes whilst you place all your fingertips on one brake at a time and apply a little backwards pressure. Check bearings in wing root are not starting to work loose in the glass cheers Rob PO Box 129, Lawson, NSW, 2783. mobile 0429 493828 ............................................. _____ From: "Redinbaugh, Kurt" <[email protected]> To: "[email protected]" <[email protected]> Sent: Tuesday, 25 August, 2009 1:36:25 AM Subject: RE: [DOG mailing list] New subscriber from the UK I have uncovered a few problems with my Dimona that are of concern: 1. The seat belt anchor plates are plywood and have severe dry rot and were not secure in their mounting boxes. 2. The wing spar boxes show some damage from the wings being moved vertically while the spar is still in the box after the pins are drawn back. 3. One of the landing gear bow bracket bolts was not properly aligned and was loose. These repairs are not too complicated but the seat belt issue is a major life safety concern. My ship has about 3000 hours on it so we are doing a very comprehensive annual inspection in preparation for the major inspection due at 3000 hours.
