Lou……..

Only a Texan would take a picture of ice!

I ran he apu on f900 087 for 2 hours this morning configuring a satcom.

Light blowing snow……..In Texas!…….

This ice formed inside the inlet.

Is this a known deal?

Looks like if we had restarted the APU  it might have been a bad day at the airport.

Two more interesting factoids.

The engine shop ran a 900 ex for quite a long time the same morning .  It came in about 45 min after we took the picture.

It had exactly the same ice on the inlet screen. But it was only 1 inch long.

While shutting down the apu, I noticed engine 2 oil temp was 50 deg c.  I had not run engine two at all, and the oat was 15 deg f.

That sounded a little suspicious, so we climbed all over the no.2 engine doing another leak check.

Sure enough there was a crack in the flange of the fgfb72155500a2 venturi pipe.

It was filling the number 2 engine cowl with hot bleed air.  That probably added to the amount of snow that melted off of the cowl and ran down into the inlet.

Bizaar set of circumstances.
