That video is quite alarming for a number of reasons.
1. The pipe is not to my knowledge an approved part. It appears to be a high pressure brake line pipe. Without a flexible couple to allow for engine vibration.
2. Its been bent crushing the inside radius flattening the pipe.
3. The leak is a full pipe split. The pin in question must be a 6" nail if its a pin hole leak.
4. The quantity and pressure that it was coming out with they were lucky there wasn't a fire.
And if the further rumours are true about the fraudulent changing of techlog Times between two towered airfields is true. The idiot that thinks they can get away with it must be barking mad as it takes 2 30 second phone calls to get the correct times.
