Do Airlines Rinse After De-icing?

Sun Feb 22, 2009 9:22 pm

Do airlines rinse their wings or anywhere the de-icing agent has touched when they arrive at their next destination, or do they just wash the planes more often during the winter period? I know military planes get pulled into their hangar and get a quick rinse after they land so I was just wondering what steps airlines take if any.

Most airlines don't really actually wash their planes, also the de-icing fluid flies off and is pretty much gone.

Quoting Mascmo (Thread starter):

If you're spraying water (im assuming) to clean a plane off after de-icing it, that would kind of defeat the purpose of de-icing, wouldn't it?  boggled

True, but he said:  Wink

Also true, even at the destination, the aircraft may well be cold-soaked, and "rinsing" would also put ice right back on the aircraft. (Surface temperature at the destination is also a factor).

Bottom line is that if de-icing fluids were harmful to the aircraft and/or required "rinsing" to prevent damage, their use wouldn't be allowed.

Yes after you pull it in the hangar I said, so that means after the flight or in the military case after they return to base get pulled in the hangar and rinsed off. I'm not saying deice it and then spray it with water right after I know that would be completely stupid!  Wink

What hanger? Most airplanes at major airlines only go inside a hanger every 4 years when they get a D check.

Usually airlines just let mother nature give the plane a bath.

In a word, no.

The only time we attempt to remove de-ice fluid is when we need to come into the hangar. The stuff is slippery as snot on the hangar floor.

Not on a regular basis. Aircraft surfaces will eventually "lose" de-icing fluid, and there's really no need to wash the aircraft regularly after fluid application. However, I wouldn't mind if they washed down the windshields, because the de-ice fluid generally leaves annoying marks that are tough to remove.

Not done.
Also Hangar visits are mainly for Major Mx/Long duration Mx or work requiring Jacking of the Aircraft.Not Line Mx.

Yes but it takes time. When a deiced aircraft arrives at the next stop, the deicing fluid is still dripping off the aircraft. Can't count the number of times that I have been called out to inspect a fuel leak, and it was deicing fluid. I t comes out of the flap fairings, and the Stabiliser area after landing.

Our aircraft are washed all the year round. They stop if the temp goes below freezing but there is a dedicated wash team and their aim is to wash every aircraft every two months.

First it's Hangar with an A.... second planes see them far more then that.... several times a year for their scheduled Inspections.

No.. in most cases no extra effort is taken in the winter month. Glycol is really not a worry anyway as it causes damage. The down side... when it comes in the hangar for inspection and they lower the flaps, if your not careful... you can get it all over you.

Just curious....Do the washing get done on line or in a allotted space with drainage facility.

Nowadays with the EPA rules the waste water has to be captured from the wash. In the old days that was not a worry. The same can be said for deicing fluid.

First, Hangar, not hanger. Planes do go to the hangar on RON for A-checks and B checks as well. C-Checks are done in the hangar, always. And you're spot on about the D's. Don't forget the S checks for Airbuses.

De-ice fluid stays on pretty much the whole day. They do wear off while inflight during the course of the aircraft's rotation for the entire day.
