As many of you may already know from other threads, last year I made a big mistake and bought a pre GT, 1983 Socata TB 20 that was in a deplorable state. It had some serious mechanical issues (yoke play/slack on both ailerons and elevator controls, loss of about 10kt of speed most probably due to rigging, etc.) Just to quote @Peter here, this plane hasn’t seen grease in years, let alone...
