Burning smell due to de/anti-icing
 

Hey there,
Last time, on approach, there was a burning smell throughout the entire plane, for a short period. The captain explained, that it's due to de/anti-icing.

Anyone heard of this before?

during approach? type of a/c?

during TO i myself experienced some odour that resembled something like vinegar (years ago).

Could also happen after landing if the RWY is affected by chemicals.

We had a fire warning going off due to contaminated air being all around the acft due to reversers.

If it was a 146, it could be de icing fluid, as the APU air can be turned during the latter stages of the approach. The APU inlet can get fluid going down it during flight hence the smell.

Could equally just be the APU producing a little oil? Or if it was Trent powered plane, particularly the T700, then it could be tiny amounts of oil coming from the engine compressor.

It was the A330.

The APU will not be started until vacating the rwy as per company procedures.

hmm???

Sound more like a bird - they have a "burning hair" smell when they are ingested, if you are lucky.

Thought of that initially, but no indication found (instruments and exterior check).

Thanks anyways. No one clearly encountered any burning smell due to de/anti -icing.

Maybe it was something else :confused:

What aircraft type?

Smell
 

I agree,

What type of aircraft, engines, type of de-ice fluid. If it is on APPROACH that sounds like an APU start up issue???

A330 with GE engines. (CF6-80E1A4)
APU was not started.

Have no exposure A330, but is it an engine hot air bleed system?
If cabin pressure,cabin heat, and antiice/deice are all calling for high volumes of (hot) bleed air, (e.g. very cold outside), high duct temp might be the source of your smell.

Did you write it up in the maint log. what did the engineers say..?

No Fault Found, obviously !:}
