How to preflight a FLOPS Hawker

Perpetual Fuel Leaks

1. Check for any fuel leakage. It seems that Flight Options has convinced the pilots that fuel leaks are OK. There are Hawkers in the fleet that have probably been flying with leaks for years now because any time a pilot writes it up, the company has them place it on a MDL and later pencil whipped by a Flight Options maintenance base. The cycle keeps repeating because the pilots have believed the guidance given by the maintenance techs in OCC.

If the LEAK forms into ANY RUNS or DRIPS it is NOT acceptable for flight until at a minimum a temporary repair has been made. NO MDL!

Use the following as a guide and stop being fooled into flying broken planes:


1. Servicing
A. Classification of leaks
(1) Acceptable leakage: This is leakage that is acceptable as is, and needs no further rectification . (CLASS 1)
(a) Slight seepage that shows no signs of forming into drips or runs. If any leak forms into a drip or run, it is no longer acceptable and requires at least temporary rectification. See next classification

(2) Leakage that requires temporary rectification: Leakage for the area listed that forms a drip or run but the drip rate is less than 1 drip per second inboard of rib 8, 3 drips per second outboard of rib 8. (CLASS 2)
If the leak rate is more than 1 drip per second inboard of rib 8, 3 drips per second outboard of rib 8, see next classification, (3) (b) below (CLASS 3)
(a) Wing tanks:
• Not more than 1 drip a second, inboard of rib 8.
• Not more than 3 drips a second, outboard of rib 8.
(b) Ventral tank:
• Not more than 3 drips a second.
NOTE: Do a permanent repair at the earliest opportunity.
(3) Leakage that requires immediate permanent repair:
(a) Any leak caused by a crack or other structural damage or defect.
(b) Any leak more than those quoted in paragraph 1.A.(2).

Also...........

If one of your main landing gear tires appears low, chances are, you are grounded. The maximum pressure loss allowed is 10% of maximum tire pressure. If it exceeds 10%, both tires on the effected side must be replaced.
They must also be the same brand, i.e. Eagle, Goodyear, etc...

If your ventral tank indicator is hashing when empty (usually a bad sending unit) you can MEL it, however, the MEL indicates an (M) procedure. A mechanic must verify the ventral tank empty
before each flight.

If your emergency window is fogging up, that's a no no (go). Visibility through the window should be clear and unobstructed. If foggy, you have bad dessicant crystals and it must be addresed.

Hawker Proline:

During a noise abatement takeoff, if you get the "WIND SHEAR" aural warning on rotation, there's a software problem aboard.

During flight, if you get the red "TRIM" annunciator located above the airspeed ribbon, you have a flight contol issue. This has NOTHING to do with the auto pilot. It's caused (usually) by the lack of or wrong type of lubricant in the elevator trim actuator.

Hope this helps.
