Section G5 - Pitot, Static, and AOA System Leak Check

Move the flight controls through all extents multiple times to confirm there is no
Move the flight controls through all extents multiple times to confirm there is no
interference between any tubing or wires and any flight controls or the flaperon linkage. Inspect
for interference with the flaps in all positions.
NOTE: When performing any AOA, Static or Pitot system pressure test on a Dynon
SkyView system it is required to be at Software Version 15.0.4 (or greater) and all testing
must be performed in the SETUP MENU > HARDWARE CALIBRATION > ADAHRS
CALIBRATION > PITOT/STATIC TEST MODE.
CAUTION: During initial AOA system installation testing the AOA tubing will be temporally
connected to the ADAHRS Pitot port. Do not fly the airplane without connecting all AOA,
Pitot and Static tubing to the proper ADAHRS ports.
This test must be used to test AOA system plumbing integrity during initial AOA system
installation.

Install both wings and engage both spar pins.

Disconnect the pitot tubing from the ADAHRS pitot fitting, connect the AOA tubing to the
ADAHRS pitot fitting.

Using a 35cc syringe, push the plunger in to 7.5cc, use modeling clay to hook-up the syringe
and a vacuum hose to the AOA port.
Turn on the EFIS (see Dynon setup NOTE above), use the syringe to slowly and carefully push
air into the AOA port. Look for an airspeed indication on the EFIS, push-in the syringe until 130 kt
indicates.
Start stopwatch when EFIS indicates 130 kts and note the airspeed ______ kts after one minute.

Move the left wing tip back and forth, as per the RV-12 Maintenance Manual Chapter 3 Rear
Spar Doubler section, while performing the AOA system leak test to verify AOA system
integrity.

Maximum allowable AOA system leak rate is 10 kts in one minute.
NOTE: If the AOA system does not hold test pressure for the required time inspect the
modeling clay to wing seal before inspecting other AOA system components. Inspect and
repair or replace any faulty AOA system components as necessary. Re-test AOA system
plumbing integrity any time the system is “opened”.

Reattach the pitot and AOA tubes to the proper ADAHRS port fittings.
NOTE: The AOA system plumbing must pass this leak test during every inspection.

Using 35cc syringe or equivalent, push plunger in to 7.5cc, hook-up syringe & vacuum hose
to pitot tube, turn-on EFIS, use syringe to slowly and carefully push air into the pitot tube, look
for airspeed indication on EFIS, push-in syringe until 130 kts indicates then stop pushing-in.
Start stopwatch when EFIS indicates 120 kts and note the airspeed ______ kts after one minute.
(Maximum allowable pitot system leak rate is 10 kt in one minute.)
