C. Inspection
A ground check of entire deicer system should be made at least every 100 hours.
Before checking system, all deicers should be inspected for damaged areas and repaired according to
procedure in this section outlining cold patch or vulcanized repairs. In order to check system, refer to
Chart 2 and the paragraph Final Test and Adjustment of Pneumatic System for operating pressure and
check procedures.
CHART 2
OPERATING PRESSURES
D. Ground Procedure
After test pressure range is established, connect an external source of air providing this pressure and a
pressure gauge to pneumatic deice line at manifold assembly. Disconnect deice line from manifold to
accomplish test. Deicer system should be within one psig of recommended operating pressure with
each inflation cycle.
If deicers do not reach operating pressure, check inflation time to ascertain that solenoid valves are
open specified length of time (six seconds). If this is not cause of trouble, or if boots deflate slowly,
lines or valves may be plugged; then lines should be disconnected and blown clear.Check timing of
system through several complete cycles. Boots ON six seconds, then OFF. Wing and empennage boots
operate separately. If cycle time is off specified time, determine and correct the difficulty.
Inflation must be rapid to provide efficient deicing. Deflation should be complete before next inflation
cycle of the boots.
E. 100 Hour Inspection
(1) Make the following checks at each 100 hour inspection of airplane:
(a) Carefully inspect deicers for evidence of damage or deterioration. Repair or replace damaged
boots.
(b) Resurface boots showing signs of considerable wear or deterioration.
(c) Inspect all pneumatic deicing system hose connections. Replace deteriorated sections on non-
kink hoses.
(d) Check operation of boots and operating pressure of the system as outlined in this section.
(e) If new or replacement boots have been installed, check tube inflation to make ensure air con-
nection stems have been properly connected.
(f) Disconnect all system drain lines and check for proper drainage.
(g) Check on-off control switch for freedom of action. Check associated electric wiring.
(h) Clean or replace air filters.
