407 Driver Posted March 10, 2003 Report Share Posted March 10, 2003 Can anyone shed some light on a recent problem I had. On Saturday, my steam-chicken governing system required adjustment on virtually every take-off and landing. (we''re talking HP kit with the 4 way beep switch). I matched Q''s, then pull in take-off power and see a 10% Q split, so I beep L or R to rematch 1 and 2 Q''s, then require another massive beep to rematch on final, this happened again and again, my thumb was very tired after a full day of this? what''s up?

CTD Posted March 11, 2003 Report Share Posted March 11, 2003 Did she just come out of maintenance? Just change environments? Is the split the same each time? Sounds like a bad Nf rod setup, an air leak, or a governor going south. Quote Link to comment Share on other sites More sharing options...
407 Driver Posted March 11, 2003 Author Report Share Posted March 11, 2003 Not just out of maintenance CTD; environments...well it was a whole lot colder on Saturday; and Yes, I have a hunch that #2 is about to go south...I''ll be flying with my hand on that throttle Quote Link to comment Share on other sites More sharing options...
Dan Posted March 11, 2003 Report Share Posted March 11, 2003 If this is the case. Why not change it now to see if that is the problem, before it causes more trouble than rolling of the throttle. Quote Link to comment Share on other sites More sharing options...
CTD Posted March 11, 2003 Report Share Posted March 11, 2003 It is - that''s why he can have a part for it tomorrow instead of 6 weeks Quote Link to comment Share on other sites More sharing options...
407 Driver Posted March 11, 2003 Author Report Share Posted March 11, 2003 It worked normally all day today, go figure? We''ll keep watching it, it may have been a spot of ice in the system, to cold (-24c is too cold for me?) or just one of those unexplained things that happen in steam-chickening. 1 Quote Link to comment Share on other sites More sharing options...
CTD Posted March 12, 2003 Report Share Posted March 12, 2003 I take it from your discription that it settles out with a split? If it splits in transit, then I''d say go after your accelerations. Tough call without seeing it. Keep your eyes on it bud, and your hand on the tap. Quote Link to comment Share on other sites More sharing options...
407 Driver Posted March 12, 2003 Author Report Share Posted March 12, 2003 Some 212''s do have a Q split on increasing or decreasing Q, this one didn''t. Just that one day it seemed to have one slow governor. I''ve had this aircraft since Jan 10, with no problems. It was an old hard-landed hull (N212HT? 2,900hrs) from Texas, that we rebulit top to bottom. Thanks for you expertise CTD. Quote Link to comment Share on other sites More sharing options...
dclarkson212 Posted May 22, 2016 Report Share Posted May 22, 2016 its the upper bearing in the TCU. there is a SB about if the bearing is worn everytime you take off the balance beam will reposition a little bit. I know you will say the beam has been fixed so it can't move. it can and does. try a new TCU . 1 Quote Link to comment Share on other sites More sharing options...
