JefRfrey,

found an interesting item,.

while checking the wing anit-ice valves,. we noted the R/H wing ice va=ve was slow to open, and sometimes did not open. when we selected L/H wing=valve to open, it took 5 seconds,. the R/H valve opens in 15 seconds when =t worked,. this is original valve. we can tell valve operation with Rise i= TGT from engine, and drop in PSI in supply duct. at Ground idle the airdu=t indicates 13psi, when you select wing anti-ice valve the psi drops to 6p=i, indicating the valve is open. I will research price and=availably,. its not worth the risk to have the valve changed Monday mornin=, its about a 6 hour change. I can schedule valve change on Saturday in Pa=m Bch with Gulfstream,.

I can't say this is our issue, since we have tried, both cowl and wingranti-ice valves during flights,. but I did select wing and cowl anti-ice d=ring our decent into Newark on last flight. If this valve is remaining par=ially open, I cant imagine it would cause a vibration.

tests for tomorrow flight:

-depart with all to cockpit vents closed.

-after departure, pull the circuit breaker to SAT/TAS probe air v=Ive, to assure the WOW curcuit (Weight On Wheels) is closing this val=e.

- fly=un-pressurized, -during climb, we select should wing have anti-ice smooth heat flight -during since decent, NO air at will 12,500ft, be coming select i=to both cabin bleed from switches engines. to manually OFF and close outflow valve.

thx
