PROBABLE CAUSE: "The cause of the accident was the failure in flight of the starboard outer wing in upward bending due to tensile overloading of the lower spar boom at station 323, probably induced by a combination of manoeuvre and gust loading when the speed of the aircraft was in excess of 260kts.

From your link:

• 445 built
• 37th loss
• 20th fatal accident
• 11th worst accident (at the time)

It would appear the Comet was not the only problem child in the British hangar.
