Pre/Post Flight Inspection - Aqua Lung SEA MK User Manual

pre-Flight Inspection
The pre-flight inspection shall be performed on the SEA prior to each
flight by the air crew member to whom the unit is assigned. Pre-flight
procedures are as follows:
WARNING: Strict compliance of pre-flight and post-flight
inspections shall be adhered to by all air crew members
utilizing the SEA. Any signs of discrepancies shall be reported
immediately to maintenance personnel.
1. With the system off, visually inspect the SEA for signs of damage.
Inspect front cover, exhaust cover and fittings for tightness. Inspect
for tamper dot (if command uses tamper dot) on front cover. Inspect
hose for cuts and blistering. Inspect for contamination, dirt and signs
of corrosion.
CAUTION: Do not press the purge button when the SEA is
on. Purging of the SEA will deplete the pressure below the
"GREEN ZONE" and it will have to be topped off by mainte-
nance personnel
2. Turn the SEA "ON" by rotating the on/off knob to the left (counter-
clockwise), the red indicator ring shall not be seen through the elon-
gated holes on the knob. Ensure that the gauge reads in the "GREEN
ZONE". If the gauge does not read in the "GREEN ZONE" report
discrepancy to maintenance personnel.
post-Flight Inspection
1. Upon completion of flight, turn handwheel off (clockwise), so that red
indicator ring is visible through the elongated holes on the handwheel.
Depress the purge button to relieve pressure in hose and second stage.
Check SEA for signs of damage and contamination. Report discrepan-
cies to maintenance personnel.
