McRae's AS355 (350?) Lost drivebelt!

by "Sla#s" <phil@[EMAIL PROTECTED] > Sep 27, 2007 at 07:49 PM

I am amazed that anyone could write such utter rubbish!
Don't newspapers check anything nowadays?
Apparently they can't find the "drivebelt" to the main rotor! A Squirrel 
doesn't have one!*
And why haven't they noticed yet that it's an AS350 single not an AS355
Twin 
Squirrel?
At least some of the comments at the end show some common sense.

A plea for the media to wait for the AAIB re****t rather than print this 
uninformed speculation

McRae crash blamed on fault in helicopter
RICHARD ELIAS
THE helicopter crash which claimed the lives of rally ace Colin McRae, his

son and two other passengers could have been caused by the failure of a 
component which links the engine to the rotor blades, Scotland on Sunday
can 
reveal.
Police sources say they are almost certain the tragedy was caused by 
mechanical failure rather than pilot error. It is understood one of the 
theories being examined is whether the Twin Squirrel's drive belt failed, 
causing a sudden and catastrophic loss of power.

Sources close to the inquiry claim that no trace of the belt has yet been 
found, a possible indication that the vital component broke - or 
disintegrated - immediately before the accident.
McRae's helicopter crashed in a wooded area on his Lanark estate last 
Saturday afternoon. The driver, 39, died instantly along with his 
five-year-old son Johnny, his best friend Ben ****celli, six, and family 
friend Graeme Duncan, 37.
Experts from the Air Accident Investigation Branch (AAIB) have been
working 
with Strathclyde Police to try to establish what caused the tragedy.
Although the official re****t will not be made public for at least several 
months, initial findings appear to indicate a fault with the aircraft and 
not the pilot.
Officially, the inquiry team is keeping an "open mind" about the possible 
causes but they privately admit to having "virtually ruled out" pilot
error.
A police source said: "It looks as if it was a mechanical fault, something

which they knew nothing about and something they could do nothing about
once 
they took off."
According to another insider, the inquiry is focusing on a specific part
of 
the Eurocopter Twin Squirrel which, despite an intensive search, has yet
to 
be found.
The drive belt transfers power from the engine to spin the rotors and must

be regularly maintained and replaced.
The source said: "Every part of the helicopter except for a drive belt can

be accounted for. This part is giving the crash investigators the greatest

cause for concern."
The aircraft, which costs around £500,000 new, is one of the world's most 
popular helicopters and has an enviable safety record but has been
involved 
in other high-profile incidents.
In May, Chelsea FC director Philip Carter, 44, and his 17-year-old son 
Andrew died, along with family friend Jonathan Waller and pilot Stephen 
Holdich, when their helicopter crashed in Cambridge****re as they returned 
home from watching their club play Liverpool in the Champions League.
In 1996, multi-millionaire Chelsea director Matthew Harding died along
with 
three others when the Twin Squirrel he was flying crashed in the Che****re 
countryside.
The McRae family declined to comment on the cause of the accident but 
Colin's father, Jimmy, has already stated that he does not believe his son

caused the crash.
A spokesman for the AAIB declined to comment, saying the inquiry was still

ongoing and would not be completed for some months.
No one was available for comment from Eurocopter, the French-based 
manufacturers of the Squirrel aircraft.
Aberdeen-based aviation expert Jim Ferguson said: "People like the
Squirrel. 
They are a nice little aircraft and they are very popular, reliable and 
normally safe."

* OK it has a hydraulic belt but that failure is a controllable situation.
