Hi all,
as per our company regulations, water drains are part of the DAILY CHK. fleet wide. when the A/C is on ground for atleast 3 1/2 hrs. At outstations where temperatures are low, we have the option of deferring it till the A/c gets to Base by making a tech log entry for the task...malfunctions in probe indications is a very chronic problem on ALL Airbus A/c due to water contamination..
