(Refer to Fig. 401.)
CAUTION: REMOVE THE NOTED SCREW FROM THE PITOT/AOA PROBE ONLY.
DO NOT LOOSEN OR DISTURB OTHER MOUNTING HARDWARE.
NOTE: The fastener securing the grounding jumper to the probe shall be installed using
torque required to bring the bearing faces into positive contact and have Loctite
242 to applied to the screw threads.
A. If required for the LH Pitot/AOA probe (Fig. 401, Sheet 3), install the grounding jumper (7)
to the probe (4) using the existing washer (14) and screw (13) from the previously
installed grounding jumper.
B.
If required for the RH Pitot/AOA probe (Fig. 401, Sheet 4), install the grounding jumper
(7) to the Pitot/AOA probe (4) using the existing washer (14) and screw (13) from the
previously installed grounding jumper.
C. Install Pitot/AOA probe (4) and gasket (6) in structure (1) and align holes.
D. Attach Pitot/AOA probe (4) to structure (1) with five screws (5) .
E. For the LH Pitot/AOA probe (Fig. 401, Sheet 3), install the grounding jumper (7) to the
aircraft structure by placing hex head screw (11) through hole (12) and securing the
grounding jumper with flat washer (10) , lock washer (9) , and self locking nut (8) .
F. For the RH Pitot/AOA probe (Fig. 401, Sheet 4), install the grounding jumper (7) to the
aircraft structure by placing hex head screw (11) through hole (12) and securing the
grounding jumper with flat washer (10) , and self locking nut (8) .
G. Do electrical bonding of Pitot/AOA probe (4) to structure (1) . Refer to
AMM-20-03-00-051-801 – Electrical Bonding - Maintenance Practices. Resistance must
be 2.5 milliohms or less.
H. Do electrical bonding of aft VCS door (12) per instructions in AMM-21-10-15-041-801 –
Aft VCS Door Actuator - Installation.
I. Connect electrical connector (2) to Pitot/AOA probe (4) .
J. Install Auxiliary Heater electrical connector (17) to bracket (16) .
K. Secure electrical connector (17) with jam nut (15) . Torque to 35-45 lbf.in (4.0-5.1 Nm)
L. Connect Pitot/AOA Auxiliary Heater electrical connector (17) to aircraft harness.
CAUTION: DO NOT USE EXCESSIVE TORQUE. TOO MUCH TORQUE CAN
DAMAGE AND DEFORM PLUMBING LINES, STRUCTURE, AND
FASTENERS.
M. Connect Pitot tube assembly (3) to Pitot/AOA probe (4) . Torque to
20-30 lbf.in
(2.3-3.4 Nm).
