Fixed Gear Bolt failure

Bolt failure under body weight, nil injuries. Suspicious for stress corrosion cracking. Currently under Ix with advice from David Reeve (QLD), other fixed anchors in this area may be at risk of failure.

Update 1/7/2020 Per D.Reeve - highly likely result of sulphide stress cracking (rather then stress corrosion cracking). Further workup still pending.
