212 governor

[407 Driver]

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?

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.

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

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.

Geez, I thought it was just beacause it was a Bell...

It is - that''s why he can have a part for it tomorrow instead of 6 weeks

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.

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.

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.
