Tércio Rodrigues Posted June 4, 2014 Report Posted June 4, 2014 Hello everyone! I'm looking for a tachometer for a 1989 M20J MSE, 28V, IPM says it's P/N is 880039-515, anyone have a spare one? My hole is 2-1/4'' And still, how can I find a tachometer compatible and aprooved for my plane? And if it's not too much to ask, could anyone explain to me the difference between TSO, PMA and STC? Thanks! Quote

Tércio Rodrigues Posted June 4, 2014 Author Report Posted June 4, 2014 Cabanaboy and Marauder, thanks for your reply! Actually, I have one of this R-1, but it's damaged and I was looking for the original one because I'm not sure if the R1 is certified for it. That's why I asked about the TSO, PMA and STC... Do you know something on it? Thanks! Quote
Marauder Posted June 4, 2014 Report Posted June 4, 2014 The EI offering is fully certified as a primary in our planes through an STC. http://buy-ei.com/portfolio/r-1/ http://buy-ei.com/wp-content/uploads/2013/06/STC-AML-R-1.pdf Sent from my iPad using Tapatalk Quote
