(Beech/Textron current pricing), and then you get a $7,000 bill back on your core for a bad solenoid! Your OSG was fine but the solenoid failed to actuate! So, again, this OSG test is more about the test solenoid than the OSG itself. This is exactly why many seasoned King Air pilots skip the OSG test altogether.
Yes, the OSG test does check the function of the OSG, but it also tests the test solenoid. Unfortunately, that pesky solenoid is far more likely to malfunction than the OSG, leading you to think you have an OSG problem when you don’t.
If you want to test your OSGs, by all means do so. But consider doing a double-check with your power levers immediately following; and maybe stash a mallet somewhere ... just in case. KA
