I've seen photos of some local Aircraft covered in Ash in Surabaya.
Any photos of our 777 HNL which was or still is stuck there??

Must be a huge pain in the a** getting all the Ash off the Jet without contaminating the Aircraft systems further.....do they wash it off??

Volcanic ash is high in silica....using water has a good chance of putting this cement like material into every nook and cranny......
Blowing it off is possibly best ...but even then anything high pressure wise it would be like blasting with sandpaper.....

Brush slowly and with care...overall it aint good news

MM 05-51-31 Volcanic Ash Ground Fallout Conditional Inspection

2) If any ash is found, remove all traces of the ash, including areas such as the fuselage crown, horizontal surfaces, inlets, and exposed chrome common to landing gear.

(a) If vacuum equipment is available and the ash is not wet, use the vacuum to remove the ash contamination from the airplane surfaces.

(b) Rinse the ash from the airplane exterior surfaces.

NOTE: Volcanic ash is known to contain trace amounts of Sulphur Dioxide, and when mixed with water can result in a mild acidic solution.

1) Make sure you remove ash from engine and APU inlets, areas around probes and ports, and ram air ducts.

2) Thoroughly rinse sensitive areas such as windows and seals with sufficient quantities of water to remove any contaminants.

Isn't HNL the el-cheapo ex Boeing demo a/c?

Maybe the cremation is overdue:hmm:

Yes it is the first 777 ever built - should be treated with respect - just like a Convair.:)
B-HNL will be 20 in July:ok:
Cutting off the cockpit and turning it into sim would not be a fitting end.:(

Master Caution

I hear ya:cool:

I still have a photo somewhere of HFX's nose section sitting outside the old HAECO hangar after it's swim in the harbour.

Have heard that Boeing purchased her back, or at least have first refusal from CX , so when they retire her she can head back to Seattle and end her days in a museum.

HNL arriving back now from SUB.

Engineers got there early and managed to cover all the vital bits and it was only light Ash on the Aircraft that washed off ok.

All good.
