The Scottish Executive has found that
Computer Weekly
uncovered new evidence over the reliability of the Fadec (Full
Authority Digital Engine Control) safety-critical software
installed on the type of Chinook helicopter that crashed on the
Mull of Kintyre in 1994.
The Ministry of Defence has repeatedly said that no new evidence
on Fadec has emerged since a RAF Board of Inquiry blamed the pilots
for the crash, which killed four crew and 25 senior intelligence
and police officers.
Continuing public concern over the alleged injustice of the
RAF's decision to blame the pilots has led the Lord Advocate in
Scotland, Colin Boyd QC, to order a review of evidence connected
with the accident.
The result of the review, by Crown Counsel, found that
Computer Weekly's evidence on Fadec was "new information"
which could "reinforce" the results of a 1996 Sheriff's Fatal
Accident Inquiry, that said there were doubts over whether the
pilots could be blamed.
The MoD maintains that there is "absolutely no doubt whatsoever"
that the two dead pilots of Chinook ZD576 were grossly negligent.
However, Computer Weekly and Channel Four News have
highlighted potentially serious problems with the helicopter's
safety-critical Fadec system.
The RAF and the MoD are now becoming isolated in their view that
there is no doubt over the cause of the accident. A recent
investigation by three fellows of the Royal Aeronautical Society
raised new uncertainties.
Doubt has also been expressed by dozens of MPs and Lords, and
hundreds of specialists who read Computer Weekly.
The Lord Advocate said in a letter to Scottish MP Kenny
MacAskill that he had asked Crown Counsel to review information
published since the 1996 Scottish Fatal Accident inquiry
"principally concerning Fadec".
Included in the inquiry was Computer Weekly's material,
which includes a 140-page report, RAF Justice, published on the
Internet, which found that there had been a cover-up of problems
with the Fadec.
Counsel also studied papers from the original RAF Board of
Inquiry and a Fatal Accident Inquiry by a Sheriff in Scotland.
Boyd does not rule out problems with Fadec as a possible cause
of the accident. He said: "Insofar as the new information about
Fadec invites speculation as to another possible cause for the
crash, it may be thought to reinforce the Sheriff's inconclusive
determination as to the cause of the accident."
However, in the letter, Boyd admits that the Scottish Executive
has no power to overturn the finding of the RAF Board of Inquiry.
"The determination by the RAF of the cause of the accident is a
matter for the Ministry of Defence and not for me," he said.
