Johannesburg - A
document with crucial information about the final hours of the
Helderberg, which crashed into the sea in 1987 off the Mauritius
coast killing everyone on board, could have been forged or
deliberately changed. This has emerged from documentation
released by Civil Aviation Authority Director Trevor Abrahams.
"If the alleged forgery can be proven, then all
information submitted to the Margo Commission at the time
regarding conversations between the Helderberg and Mauritian
ground air control stations is under suspicion," said Mark
Whale of the Scorpions after he was presented with the document.
Whale is conducting a probe into the disaster on instruction
from the National Prosecution Authority.
The document involved maps and the time and frequency of
Helderberg Captain Dawie Uys's contact with air control ahead of
the crash.
Prior to the Margo Commission, evidence suggested that
contact was made with a ground station at 23:13 and again at
23:48 with the control tower at the airport in Mauritius, when
Uys informed them that he was initiating an emergency landing.
However, the new document, released by Abrahams about two
months ago, reveals that there was never a contact conversation
at 23:13. Abrahams's document did, however, state that there had
been contact with Mauritius at 23:32.
Aviation experts point out, and Whale confirms, that the
flight recorder of an aircraft runs for thirty minutes before
automatically recording from the start again if nothing is said
in the preceding 30 minutes.
A person or persons could, therefore, deliberately register
the contact time as 23:13, creating a false impression to the
Margo Commission that more than thirty minutes had lapsed
between the 23:13 contact period and the last contact at 23:48.
The commission would, therefore, get the impression that the
23:32 contact had never taken place.
Uys's report to Mauritius at 23:32 could have been of such
interest that a person or persons deemed it necessary to
withhold the information from the Margo Commission.
Whale added: "If the contact times had been interfered
with intentionally, it renders under suspicion all other
versions of conversations submitted to the Margo Commission that
Captain Uys made on the night."
Abrahams failed to respond to several Beeld enquiries seeking
clarity over the contact times.
However, he did say to Neels van Wyk, who is conducting an
independent inquiry into the Helderberg in the US, that the
23:32 contact time on his document had been secured from an
unscrambled tape used in the control tower at Mauritius on the
night of the crash.
He added that he believed the unscrambled tape of the last
conversations captured on the Helderberg flight recorder (as
submitted to the Margo Commission) had not been made in the last
30 minutes of the flight.
