455 Bravo Uniform
Final Approach
I’m working on my commercial training. We’ve flown a couple hours doing various manner of stalls and slow flight. I have “one o’ dem canards” in a 182 so we end up with some “impressive” deck angles
The last flight, the vac pump low vac light flickered while on the ground taxiing back after the flight at low rpm. After today’s flight, vac stayed at 4 and light remained at all times during taxi. Roughly 400 hrs on the pump; maybe time? (I don’t know if vanes were inspected at last annual).
Question: Can the vac pump be negatively affected with oil piling-up inside the rear accessory case area? IO-470
Could high AOA oil immersion of the rear case also affect mag, fuel pump, and starter too?
Stupid question??
