Hi Guys,
I am really hoping the Mod's can upload the file for us here today, they may have been out of the office on Fri....
Having allready recieved quite a few mails asking for the report...I have copied here the critical part of the report so long for you to browse.... (It's just a little too big to mail to everyone guys...I'm sure we will have it up here today in full.)
"2.
ANALYSIS:
2.1 Available information indicated that fine weather conditions prevailed in the area at the time of the flight and accident. The prevailing weather conditions were therefore not considered to have any bearing on the accident.
2.2 According to the last maintenance record entry found in the SACAA aircraft file, the aircraft was properly maintained. All flight control surfaces were accounted for, but control continuity could not be confirmed.
2.3 The pilot held a valid pilot licence as well as a valid aviation medical certificate that was issued by an SACAA-accredited medical examiner. After the accident and subsequent inspection, the SACAA investigators noted that the aircraft
right wing leading edge material failed in-flight, folded up and resulted in loss of control.
2.4
Samples of the wing material were removed from the accident aircraft and tests and examinations were carried out. All the samples passed the tests and it is still uncertain where loads great enough to cause such failures could have come from.
2.5 It is the opinion of the investigator that, whilst the aircraft was flying, an inboard section of the starboard side wing cover (material) started tearing and that caused the aircraft to lose lift on the starboard side wing. The aircraft went into a stall and spiral spin from which the pilot could not recover resulting in a crash. Post impact fire erupted and fatally injured the pilot and passenger.

CONCLUSION:
3.1 Findings:
3.1.1 The pilot was a holder of a private pilot licence with the aircraft type licence endorsed in his logbook.
3.1.2 The pilot’s medical certificate expired on 30 June 2010, and had no restrictions.
3.1.3 The pilot and the passenger were engaged in a private flight.
3.1.4 The Approved Person that certified the last inspection was accredited by the Aeroclub.
3.1.5 No records of any fuel uplift could be found because the aircraft’s flight folio could not be located.
3.1.6 The aircraft logbooks could not be located or found.
3.1.7 According to the SACAA aircraft file, the last annual inspection was certified by an approved person on 15 December 2007.
3.1.8 The Authority to Fly was valid until 5 January 2009.
3.1.9 The flight was conducted in fine weather conditions.
3.1.10 The right wing material failed in flight resulting in a loss of lift to the starboard side of the wing.
3.1.11 The aircraft stalled before crashing and being destroyed by the impact forces and the post impact fire.
3.1.12 Both the pilot and passenger were fatally injured as a result of this accident.
3.2
Probable Cause/s:
3.2.1
The right wing leading edge material failed in-flight, resulting in a loss of lift and subsequently the aircraft stalled and crashed.
All the samples passed the Bettsometer tests as described in Streak 3 Maintenance Manual Section 53.30.00. The values used were the 1 360 g limit as prescribed.
It is uncertain where loads great enough to cause such failures could have come from "
