PT6 Engine care..
Hi Guys,
I would appreciate your inputs on pilot engine care, especially on the PT6 range for B1900's. Currently we advise our crew to do: 1. Bleeds off, Environ off t/o 2. Reduce pwr t/o - runway permitting 3. Start into wind 4. 2 min idle before shutdown 5. Start with ITT below 200 deg C on through flights. 6. Good Bat V Any other tips will be appreciated:ok: |
All of that is good, just remember to stay within flight manual parameters

At first glance it sounds a little overboard. But with the temperatures you guys see down there I can see why you wouldn't want the flowpacks on until after takeoff anyway.
How do you figure out a safe power setting for the reduced power takeoffs? We run our PT-6s consistently at redlines and almost always get over 10 000 hours between overhauls. 2 minute idle is an excellent rule. |
The numbers are good. Max motor for start before introducing fuel is important (rather than introducing at minimum %ng). Cool down with bleeds off, of course.
Ground power is always preferred on the starts; you'll get higher max motor, and cooler starts. |
V1.Ooops has some very interesting stats about multiple fatal accidents in DHC-6 (PT6 powered) - 7 out of the last 10 would have been avoided if the pilots had used full takeoff power as specified in the POH for takeoff. Bending an airframe will cost far more than trying to get a bit more life out of the engine will save.
My gospel tips:
