5. NACA Inlet Assembly
A. NACA Inlet Assembly Inspection
(1). Visually inspect NACA inlet assembly.
(a). Inspect general condition of outer
surface of inlet.
(2). Inspect inlet (flapper) door (used with
Inlet Particle Separator) for signs of
wear or any other form of damage.
NOTE:
Ref. Inlet Door Actuator Assembly
Installation for actuator rod end adjust
ment.
(a). Ensure inlet door seal mates securely
with inlet assembly for proper
sealing in the closed position.
(3). Inspect screen (used with screened inlet
panel) condition and attachment.
(4). Inspect attaching hardware for security
of installation. Inspect for wear, cracks
or any other form of deterioration.
(a). Replace loose, missing or damaged
hardware.
(5). Inspect inlet door actuator wiring (if
applicable) for damage, corrosion and
security of installation.
(6). Inspect inlet door operation (if required)
(Ref. NACA Inlet Assembly Operational
Test).
B. NACA Inlet Assembly Operational Test
NOTE:
Operational test applies only to NACA
Inlet used with Inlet Particle Separator
(1). Verify NACA inlet doors are in the full
closed position.
(a). Ensure inlet door seal mates securely
with inlet assembly.
(2). Verify override switch, located on center
control panel, is in the
NORMAL
position.
External Power
(3). Apply external power (Ref. Section
96-00-00) or turn on aircraft's electri
cal system.
(4). Verify NACA DOOR lights or IIDS
alphanumeric display illumination.
(a).
900 CONFIG
(aircraft with NACA
modification) - Verify NACA lights
show
CLOSED
. (
NACA DOOR
lights should always be illuminated
in either the
CLOSED
or
OPEN
indication).
(b).
902 CONFIG
- Verify
NACA DOOR
is not displayed on IIDS alphanumer
ic display. (
NACA DOOR
message
should not appear on IIDS alphanu
meric display at any time unless
doors fail to operate correctly. The
message only illuminates when an
anomaly occurs).
(5). Fit a piece of vinylite or similar flexible
tubing tightly over end of pitot tube.
NOTE:
Observe NACA inlet doors and airspeed
indicator while pressure is increasing.
Do not exceed
100 KIAS
(6). Record the indicated airspeed when the
NACA inlet doors start to open.
(a). Fold the free end of tubing over and
roll tubing slowly to create pressure.
NOTE:
NACA doors should start to open at
approximately
47
5 KIAS
.
(b). When the observer signals that the
airspeed reading is increasing,
monitor airspeed indicator until
NACA doors start and continue to
open.
(c). Increase pressure until the airspeed
indicator reads
100 KIAS
.
NOTE:
900 CONFIG
(aircraft with NACA modi
fication) - Verify that the NACA lights
change from
CLOSED
to
OPEN
.
902 CONFIG
- Verify that the message
NACA DOOR
is not displayed on the
IIDS.
