Hi tms.Anita
I've had the following passed on to me regarding an incident in a Tayside aircraft. Its about halfway down, under PA-28, involving a pan call near Lockerbie, you may wish to read it.
Safety Data - General Aviation Report: April 2014 - General Aviation Report | Publications | About the CAA
Allegedly Tayside management initially denied a leak had been found, suggesting pilot error, then they apparently desribed the leak as a pinhole. There is a video doing the rounds....
Please, please look into all options so you can make an informed choice which suits your needs. And stay safe!
PS. Check your PMs.
