F900 Troubleshooting

Why does the door pop on a f900 during climb?

There is a HUGE  amount of pressure that pushes the door outward when the airplane is pressurized.  It causes the feet to lock in place then jump a little as the fuselage grows with pressure.  The feet must be perfectly polished and clean to prevent this.  There must be a SMALL film of grease on each foot.

 

This is the dome shaped foot on the door.

This is  the flat foot on the air-frame. interestingly it has a slight pattern of vertical lines that are worn away on the contact patch.

the tiny polished spot is the contact patch1474911029365-546824352

 

 

The contact patch for each foot is only about a quarter inch around or less in some places

looking at the pressures applied to these feet:

Door is about 34 inches by 80 inches.

2720 square inches, 9.1 psi of pressure,

24752 pounds pushing out on the door.

10 door stops, so about 2400 lbs pushing on each stop.

.25 X. 25 inch contact patch means

2400lbs / .0625 sqin = 38000 psi pushing on each contact patch …….

Default Re: Low oil pressure blinking with good pressure.

Hope this is what you want.

The low oil pressure indicator light works in two ways: it flashes continuously following a momentary loss of engine oil pressure, or it comes oN and stays oN with a complete loss of engine oilpressure.

When the engine first starts, before its oil pressure rises above 4.3 psi , voltage is applied to the closed and grounded engine oil pressure switch and the light comes oN to test the bulb.

With the engine running, voltage is applied at the WHT/BLU wire of the integrated control unit. With normal engine oil pressure, the engine oil pressure switch is open and the low oil pressure indicator light does not come oN. If the engine oil pressure switch closes momentarily (more than 0.5 seconds ) but then opens again, the YEL/RED wire at the integrated control unit will sense ground through the switch. The integrated control unit will then provide and remove ground for the low oil pressure indicator light through the YEL/RED wire. The light will flash oN and OFF until you turn the ignition switch OFF. The flashing feature will not work until 30 seconds after initial voltage is applied to the WHT/BLU wire of the oil pressure indicator flasher circuit. This delay keeps the low oil pressure indicator light from coming oN during engine warmup.

If engine oil pressure falls below 4.3 psi and does not increase, the engine oil pressure switch will stay closed. The low oil pressure indicator light will then come oN and stay oN.

“The oil light flashes when the oil PRESSURE momentarily drops below 4.3 PSI and will continue to flash until the ignition is turned off. If the oil pressure stays below 4.3 PSI, the light will be constantly illuminated.”

Intermediate refueling
Intermediate refueling can be performed through the refueling coupling (500QS), with the “REAR” switch (63Q) set to the “LO” position. The low-level float valves (L605QS)/(R605QS)/(M605QS) then control the transfer valves (L615QS)/(R615QS)/(M615QS).
The fuel truck delivers fuel into the refueling manifold (516QS) and the fuel is then transferred into the feeder tanks through the transfer valves.
Refueling is automatically stopped when the fuel reaches the normal level in the feeder tanks.
Refueling of the wing tanks and centerwing tank is performed by setting the “TOTAL REAR” switch/light (48E) to the “TOT” position.
EIED 2 (20EA) displays the quantity of fuel contained in each feeder tank and in the corresponding front tank.
