    YOU\'RE A CREW MEMBER

    Imitation being the best form of flattery here is my "you're a crew member" question.

    You and I have just departed HOU ( Houston Hobby Airport ) and during the climb out we notice that the left engine is running about 50 degrees c cooler than the other engine. All other indications are normal as expected. After level off the engine is running 100 degrees c cooler than the right engine.

    Note: The right engine is NOT running over limits, in fact it is operating at exactly the temperature you would expect given the power setting and ambiant temperature.

    What are our available courses of action?
    What do we do as a crew?

    Is the cooler engine developing full power?
    What kind of engine is this? [IMG]

    Running hot as in oil pressure or EGT? If we are talking EGT are the FF equal? RPM equal between both engines? What is the destination? Is the destination IFR or VFR? Are we going overwater?

    Based on the info you have given so far I would contiune, assuming no wet footprint problems.

    ITT is running colder than expected. Jet egines, both N1 and N2 and fuel flows are matched perfectly and producing normal thrust. Flight Departed HOU and going to RDU ( about a 2 hr. flight ). Severe clear VFR.

    Re: YOU\'RE A CREW MEMBER

    Since N1, N2, and fuel flow are all matched, and the engines seem to be producing the expected and equal amounts of thrust, I am inclined to suspect a gauge or wiring problem. Except on the first part of the SID (VUH1, over the water along the gulf) we're not overwater, and even then you're 20 miles or less from land. There are lots of "bailout" option airports along the route of flight. My answer is to discuss the situation, agree to monitor the engine indications carefully, and continue the flight. Keep track of nearby airports in case a precautionary shutdown becomes necessary, and plan to have it checked by maintenance at the destination. Any indications that make either of us uncomfortable or unhappy we divert somewhere and get it looked at sooner.

    I've had ITT fall right to zero and come back in flight before, or fall a hundred degrees for a little while and return ... so far (maybe I'm just lucky) it's only been gauge problems.

    Re: YOU\'RE A CREW MEMBER

    I'd do nothing until there is some kind of secondary indication of a problem. What are you going to have more faith in, a two million dollar motor or two bits of wire and a fifty cent gauge?

    Re: YOU\'RE A CREW MEMBER

    Tired and FL270
    Pretty much how I handled this situation last week. The problem is that there is nothing in the checklist for this situation, so its really not an emergency per se, no limits were being exceeded. By the process of elimination I determine that it was in fact a wire ( cannon plug ) problem. About 45 min into the flight it started to work normally again. I hate to continue on a flight with a "problem" but this one had no reason to cut the fligth short. It is a judgement call and in this business there will always be second guesing, I'm sure there are some here that think a landing would have been prudent, I won't argue with them because if that is their judgment I accept it. This is one of those situations where there is no one correct answer, you just do the best with what you got and trust your training and instincs.

    Re: YOU\'RE A CREW MEMBER

    I agree, all other indications normal, continue, keeping an eye on things to ensure things don't escalate. We actually have a comparative check of ITT (Delta-T check, difference in ITT during 10000 ft/Cruise checklist) to make aware of problem associated with non-normal ITT. But if everything else was normal, continue.

    We actually had a simliar occurence, only with the Engine Oil Temperature gauge. It was pegged out to the high side, way above 130 degrees. Sometimes it would flick and settle on the red line, and flick very quickly green, then back to pegged. We called MX control to make them aware of the problem, were checking other indications, and preparing for a diversion to Moline, IL which we were almost over (coming back from Cedar Rapids, IA). Every other indication was normal (including Oil Pressure, which would have been a giveaway to a problem with pegged temperature) but all was normal. Turned out to be faulty gauge wiring.

    Re: YOU\'RE A CREW MEMBER

    Our engine indication problems in the -200 have always been gauge-related, usually (as in 650s case) cannon plug wiring. Replacing the gauge or even just hitting the cannon plug with contact cleaner has cleared up our problems.

    The oil temp gauge problem FC describes would concern me a little more ... no arguments with the way you handle it, but you've got a bit more information to go in in 650's example that tells you everything is probably OK. The oil temp I'd watch more closely, but again be prepared for diversion and/or possible precautionary shutdown.

    All judgement call assesments seemed prudent and wise enough to me.

    Re: YOU\'RE A CREW MEMBER

    50 degrees seems like tight tolerances. We've almost always got some split in ITT on the Shorts. When it got to 200 split or one wasn't reaching target torque in cruise, then I started to become cautious. We're over water at night, but the captains are pretty relaxed. I suppose that comes with experience and completely trusting the PT6 and it's limits.

    How on earth do you fly that box with wings...those planes look horrendous....shorts that is.

    Re: You are the crew member.

    If someone paid you to fly it you'd change your mind pretty quick. I've always wanted to take a look in one, I've been told it flies real nice and the cockpit is roomy.

    I'd fly one in a heartbeat. I've ridden right seat for a few minutes in a SkyVan (before I jumped out)...pretty cool plane!

    Re: YOU\'RE A CREW MEMBER

    It's a blast. Sure it's slow, but hey, I'm building time right? [IMG] The cockpit is roomy...it's the only
    one I can think of with a door for each crewmember. I think it's been said before, but it sure does
    leak when it rains. Hawaii just got hit with about a week of rain, and needless to say I was no better
    off in the seat due to the leaking overhead escape hatch. But with all it's quirks, it's smooth, stable,
    and easy to land. No complaints here.

    Umm, okay I can see where I should have phrased my question a bit differently........

    Does your company currently operate (as in fly) any of American Eagle's old SD330/360s?

    Guess I should read my posts a little more carefully before I submit them! [IMG]

    Re: YOU\'RE A CREW MEMBER

    Not sure where all of the airplanes have been. I belive
    one had the blue and red stripes. Maybe Eagle? I've
    seen pictures of one at Allegheny and one at Business
    Express. Those old birds used to the be the cat's meow
    for commuters. Riding up front is nice, but I don't know
    about the back. [IMG]
