A question . We have recently sent another 4330 Slick mag for the usual 2 year bench check. The NZ CAA approved engineer said that there is an AD which specifically requires these mags to be "overhauled " after 12 years.
Despite the biannual checks The problem seems that Champion (Slick manufacturers) want to sell new replacements od simply get rid of the "old" slick 4330 mags. A case here .. I have an unused 4330 mag (Right hand including impulse ) which is significantly older than 12 years (Serial No 93040014) which presumably the 93 is the year of manufacture. It was part of what I picked up from the purchase of VH-GNW in Australia. So theoretically it needs a complete overhaul before it can be used (not just the standard bench check and certified release note). The cost of replacement parts for these magnetos is like gold ( not helped by Trump, the US economy, and a very low NZ Dollar) SO what could be a solution ? Perhaps some official data approving time expired mags but have passed their 24mth inspection to be used for non commercial use. I would be really interested in any comments / suggestions Best regards Ian Williams NZ
