Eric Western [email protected] Australian Air Props Pty Ltd 515 Hartzell Place Bankstown Airport Bankstown NSW 2200 (02) 9790 4677 I'm impressed if you managed to run out of hours in the 6 year TBO time. I don't know anyone else who has managed to do that. Pull it off yourself if you feel comfortable doing it. Undo ALL the nuts half off then, wriggle the prop forward on the flange and undo them completely. It has to be in 2 stages due to nut clearance to crankcase restrictions Make sure someone has a GOOD grip on the prop when you take the last nut off. It might be expensive if it falls off unattended. Installation is more of an issue. You need someone with engine ratings. Specifically component replacement including the Prop. >From my experience it NEVER comes back with the pitch right or the adjustment >of the Swash Plate position isn't exactly the same as it was and usually both. Generally the prop change arm position will need adjusting at the cable and the pitch will need adjusting for best performance. Cheers.

The prop on GJD runs out of hours at end of July. I've spoken with Tom Gilbert (he does the Form 2's) and he suggests we remove it ourselves and send it off to the propellor people. Q1: Who are the propellor people? Does anyone have a name/address/email etc. they might be able to share? Q2: I don't have a Form 2 rating (just DI), but one of my friends at Leeton (Al) does. Is this enough quals to legally remove the prop, and more importantly, put it back on when I get it back? Q3: Assuming it is ok for us to remove/re-install at Leeton, does anyone have a manual or procedure for same? I'm assuming that there'd have to be some sort of checklist to follow to do the work properly. Can anyone help me out with that? Thanks in advance. John Mason - Leeton
