G. Water Leak Check
(PIR-PPS60047, Rev. C.)
The check shall be accomplished using a standard garden hose and a nozzle capable of
adjustment.
(1) Attach hose with nozzle to water tap at city water pressure. Check to ensure that there are no
leaks in the hose or fittings which would impair the check or cause other damage, with the tap
full open.
(2) The check shall be conducted with an observer inside the aircraft.
(3) All cabin and baggage compartment doors and other controllable external closures shall be
closed and latched during rainfall simulation.
(4) The spray shall be aimed directly at the openings around windows for a period of one-half to
one and one-half minutes for each window. The nozzle shall be held three to ten feet from point
of water contact.
(5) If a leak allowing water to enter the cockpit/cabin is detected, the seal or caulking shall be
reworked as required, and the check shall be repeated in the area where the leak was noted.
