Note: It is permissible to have a dry area no larger than 2 rows of holes by 2 inches long.
(10) Purge panels for at least 3 more minutes with no additional air passing though panels.
If additional air bubbles are found during this time, perform additional "shocks" and check for air
over an additional 3 minute period.
Note: Total time for a panel to purge should not exceed 15 minutes.

H. Procedure - Panel Performance Inspection.
(1) Evaluate panel performance for panel.
(a) Verify flow of panel is consistent from one end to the other.
(b) Verify dry area of a panel is no larger than 2 rows of holes by 2 inches long.
(c) Verify purging has eliminated air bubbles before 15 minutes have elapsed.
(2) If adequate panel performance is not met for a wing panel, perform the following steps:
(a) On TKS cart, confirm that pressure vessel is at least half-full with fluid.
CAUTION: Do not allow pressure vessel to run dry. If vessel does run dry, isolate that
panel and purge it individually up to 70 psi for at least 10 minutes.
(b) Purge air out of wing porous panel as described in Procedure - Purge Air with the following
exceptions: (Refer to Section F.)
1 Open only the shut-off valve corresponding to the single trouble panel to be purged.
2 Increase pressure up to 70 psi.
(c) Re-evaluate panel performance for wing.
(d) If wing porous panel performance is still inadequate, replace panel and send removed
panel to Cirrus Design for inspection. (Refer to AMM 30-10)
(e) If wing porous panel performance is acceptable:
1 Close shut-off valve at in-line pressure gauge corresponding to panel being purged.
2 Disconnect in-line pressure gauges from coupler assemblies.
3 Bleed air by energizing system on aircraft and run in "high" mode until full flow into
collection containers without air bubbles is achieved.
Note: Make connections quickly to minimize introducing air into system
lines.
4 Remove short lengths of tubing from 5/16-inch supply lines.
5 Reconnect coupler assemblies to 5/16-inch supply lines. Torque nuts to 48 in-lb (5.4
Nm) and apply torque seal.
(3) If adequate panel performance is not met for vertical stabilizer panel, replace panel and send
removed panel to Cirrus Design for inspection. (Refer to AMM 30-10)
(4) If adequate panel performance is not met for horizontal panel, replace panel and send removed
panel to Cirrus Design for inspection. (Refer to AMM 30-10)
(5) If adequate panel performance is not met for an elevator tip panel, perform the following steps:
(a) On TKS cart, confirm that pressure vessel is at least half-full with fluid.
CAUTION: Do not allow pressure vessel to run dry. If vessel does run dry, isolate that
panel and purge it individually up to 70 psi for at least 10 minutes.
(b) At the avionics bay, disconnect TKS cart and reassemble system lines.
1 Close shut-off valves at in-line pressure gauge connected to panel being purged.
2 Disconnect in-line pressure gauge from trouble line coupler assembly.
3 Bleed air by energizing system on aircraft and run in "high" mode until full flow into
collection containers without air bubbles is achieved.
Note: Make connections quickly to minimize introducing air into system line.
4 Remove short length of tubing from trouble line.
5 Reconnect coupler assembly to 3/16-inch supply line. Torque nut to 28 in-lb (3.1
Nm) and apply torque seal.

(c) Remove horizontal stabilizer access panel. (Refer to AMM 55-10)
(d) Remove cable tie securing coupler assembly to horizontal stabilizer structure.
(e) Disconnect 3/16-inch supply line feeding the coupler so that coupler remains connected to
line leading to proportioning unit.
(f) Connect one of the TKS cart lines to elevator tip panel.
(g) Connect short length of tubing to elevator tip panel 3/16-inch supply line and put other end
of tubing into collection container.
CAUTION: Do not allow pressure vessel to run dry. If pressure vessel does run dry, isolate
that panel and purge it individually up to 70 psi for at least 10 minutes.
(h) Purge air out of elevator tip porous panels as described in Procedure - Purge Air with the
following exceptions: (Refer to Section F.)
1 Open only the shut-off valve corresponding to the single trouble panel to be purged.
