kiguba Posted May 3, 2009 Share Posted May 3, 2009 Whenever we shutdown our GTC, we noticed that there's a leak coming from somewhere... We checked the oil pump and bypass valve but its doing fine. Any recommendations from you experienced guys? Quote Link to comment Share on other sites More sharing options...

DCC1598 Posted May 3, 2009 Share Posted May 3, 2009 Had this problem on my bird last year--as I recall it ended up being a bad check valve. Quote Link to comment Share on other sites More sharing options...
EClark Posted May 3, 2009 Share Posted May 3, 2009 I don't know about now but we use to have to prime the ones that was hard to start you had reach down and push the chech valve primer it was a little dangerous Quote Link to comment Share on other sites More sharing options...
pjvr99 Posted May 4, 2009 Share Posted May 4, 2009 Where is it leaking from - i.e. accessory case? or from one of the drains? Quote Link to comment Share on other sites More sharing options...

EClark Posted May 5, 2009 Share Posted May 5, 2009 (edited) If your Maints. N.C.O.'s are ok with it and the flight crews then I suggest a drip pan. Or you can have it took out and run on a test stand and check for leaks Edited May 5, 2009 by EClark Quote Link to comment Share on other sites More sharing options...
jrkaegi Posted May 5, 2009 Share Posted May 5, 2009 Does leak after shut down,( over service.) Quote Link to comment Share on other sites More sharing options...
pjvr99 Posted May 6, 2009 Share Posted May 6, 2009 Had one like this some time ago. There's a check valve inside the accessory drive, that is busy dying. Choices are: remove the GTC now and get it repaired relatively cheap, or, fly to failure. Not much you can do at maintenance level to repair this. If I remember, I'll get the TO reference to this problem ..... Quote Link to comment Share on other sites More sharing options...
