Here you are Bounce.

Pilot: Andy Wilson
Aircraft: Yak-50
Location: Bothel, Cumbria

A beautiful day in the magnificent Lake District of the UK; perfect for wandering the skies in a Yak 50, until the oil pressure drops and the engine stops.

The aircraft was on a local flight from Carlisle Airport when the engine failed due to loss of oil pressure. The windscreen became partially obscured with an oil film but the pilot was able to make a forced landing in a field, during which the aircraft was substantially damaged. He vacated the aircraft unaided, but later attended hospital as his injuries became more apparent. On examining the engine, the pilot identified that the oil pressure adjustment valve was missing from the oil scavenge pump housing. It was found in the lower cowling with no evidence of the expected wire locking. He believed that the valve had worked loose and fallen out during the accident flight, causing the oil loss.

The aircraft had recently undergone extensive maintenance at EGMJ which included an overhaul of the oil scavenge pump assembly. Initial flights following this work revealed a small oil leak in the area of the pump, which at the time, was thought to be have been remedied by an engineer tightening the small vertical bolts adjacent to the pressure adjustment valve.

Blimey! Now that was scary. I wonder if the pilot even considered he might be filming his own demise? Well done that man.

No wire locking? Now there is an engineer who will be losing a lot of sleep now.

There are instructions here about posting Youtube videos. It is very complicated though compared to most forum templates that just require you to post the URL and the template does the needed to embed it.
