Ever wonder why the standby alternator or vacuum pump isn’t working? There is a drive coupling that is designed to break if something becomes stuck. They are also supposed to be replaced every 500 hours or they can start looking like this!
In Case You Missed It
Dan Parker and the Altitude Airplane
Dan Parker was just another enthusiast looking to make his mark in aviation with some kind of crazy, notable project. Then he came across the Facet Opel, current altitude record holder, and the race was on. Since then, hes been working on his airplane full time, hoping to break the existing record, and along the way hes come up with some innovative and exceptionally efficient building and design practices.
Bad Indication or a Real Problem?
How many of us have seen an unusual engine temp/parameter indication and wondered if...
last time I looked, the vacuum pump drive spool had a 500hr OR 10 year service life whichever comes first.
Perhaps this is newer data than when you last looked, butTempest has a service letter, SL-001 which recommends replacement every 6 years.
In our glass cockpits the standby alternaotr seems pretty important. That’s why we recommend 5 years.
