Infrequent use on Turbomeca engine heads up
Was reminded today of the 7 day run to maintain oil film and fuel wetting of components , and a log book entry to back it up, any failure to do it, ie storage or heavy maintenance rendered it unservicable, you can vent it up to 3 times but then it goes back for overhaul.
potential sellers and buyers and reps are told to look for these entries ..
