Sky Shuttle AW139 ditches in HK Harbour
The only thing that puzzles me is that the HUMS was damaged from sea water. Correct me if I'm wrong, aren't they supposed to water proof to a degree?
JW, I think you are being a bit harsh. Interim reports always look similar to this. They simply state a few established facts and the detailed analysis comes later. Sometimes, if there is compelling evidence, they may make some interim recommendations.

Good Morning 212man
Oh I know I'm being somewhat harsh on the 'ol CAD, too much time spent in the area perhaps seeing how these prats operate firsthand. Gets frustrating after a while though when good intel is conveniently overlooked/hidden.

btw, hope the recruiting exercise proves successful.....cheers!

Quiz
From the HKCAD's interim report:
Q: How many times did the captain command the F/O before the F/O took such action ?
Bottle of champagne for the first correct answer.
Whilst in autorotation, he commanded the first officer to shut down both engines in accordance with the emergency procedures and the first officer carried out the commands accordingly.

Not very conclusive I'd say. The only thing that puzzles me is that the HUMS was damaged from sea water. Correct me if I'm wrong, aren't they supposed to water proof to a degree?

It could be possible that the brackish air damaged the card??

HUMS Cards
The HUMS cards (or to give them the posh name "data transfer device") are just ordinary PCMCIA cards slotted into a "cockpit display unit" which really a basic PCMCIA slot. Only real protection they have is the spring loaded cover over them. Not sure how waterproof that would be.

HUMS card
Yes, of course, but the corrosion is so quick??
For example, my wife wash a pen drive with my jeas in the washing machine (40 min at 30°C, delicate !).
she laid it and it works perfetly!
So I think that the corrosin of the HUMS card it's not due to the water crash...

Even gold contacts corrode in the HK "air", let alone in sea water! Only place I've see brass fittings turn purple, due to air pollution.

MACAU DAILY TIMES - Sky Shuttle fleet grounded

MACAU DAILY TIMES - Sky Shuttle back to full service today
MACAU DAILY TIMES - Sky Shuttle fleet grounded
With only one helicopter available Sky Shuttle had to cut its flights between Hong Kong and Macau to one every hour instead of two and suspend its services between the MSAR and Shenzhen, South China Morning Post (SCMP) reported.
MACAU DAILY TIMES - Sky Shuttle back to full service today
“Sky Shuttle Helicopters has reduced the number of daily services operated on a temporary basis, but has not suspended any of its routes,” AW told MDTimes. MDTimes tried to clarify this issue with Sky Shuttle but received no reply before the closing of this edition.

Update on Hong Kong Accident
I can't find the thread on AW139 accident (it was merged with this one?)
http://www.cad.gov.hk/reports/Accide...Nov%202011.pdf
http://www.cad.gov.hk/reports/Accide...Nov%202011.pdf
a major portion of a tail rotor blade, designated as White Blade, was found broken off from the tail rotor
The scope of work examined by QinetiQ focused on the tail rotor hub, the remained portion of the White Blade, the Blue Blade, Yellow Blade and the fractured part of the vertical tail section
After a detailed review of the QinetiQ Report, CAD noted that the examined samples of the Blue Blade, Yellow Blade and the remained portion of the White Blade indicates that these blades did not comply fully with AgustaWestland’s specifications. Manufacturing discrepancies such as undersize and high level of
porosity of the upper and lower straps of the blade samples were identified.
porosity of the upper and lower straps of the blade samples were identified.
Recommendation 2011-3:
Ente Nazionale per l'Aviazione Civile, jointly with AgustaWestland, to review the manufacturing process of the AW139 tail rotor blades to determine the causes of the
discrepancies identified in the QinetiQ Report and evaluate their effects.
Recommendation 2011-4:
European Aviation Safety Agency to require AgustaWestland to perform static, fatigue, dynamic and aerodynamic tests and analyses on AW139 tail rotor blades so as to minimise the possibilities of tail rotor blade failure which could have been caused by one or the combination of these effects.

I hope the guys from Farnborough are familiar with the issue of porosity (micro-voiding).
SM if you have a contact there, I'd like to communicate with them. Pls send a PM.
