Plane crash in Scotland


I hope this is the right place to be posting this. There was a crash years ago in Harris, and this aircraft clipped the top of 'Moadal', a hill near the village of Northton, Isle of Harris, Scotland in bad weather and exploded killing all 10 crew members. The date of the crash was 30.4.90. My brother and I climbed the hill recently and we found a small monument for the people and there are still pieces all over the place from the plane. I found this one piece that I thought was interesting (I hope it was ok for me to do this!) and I'm posting a picture to see if any of you guys can identify where it came from. Just out of curiosity!

I am not really sure what it is, although, there are a few regular posters on here who more than likely will know. Still, it is an interesting thread all the same. Welcome to TAF!

Its off a high pressure cylinder like oxygen judging by the warning its at 3300 pounds per square inch and that it needs to be used with a MK V regulator.

I have done a little digging.

An airborne early warning RAF Shackleton (tail number WR965) of No. 8 squadron based at RAF Lossiemouth, crashed into a small hill called Maodal (250 metres high), killing all 10 people onboard on 30th April 1990 around 12.30 pm.

The crash was debated in the House of Commons.

The Shackleton had been adopted as an interim measure until the AEW Nimrod aircraft could be brought into service.

The Nimrod was delayed and then cancled, but the 40-year-old Shackleton still flew on.

Questions were asked why the aircraft was operation below 1,000ft, when normally it would be flying at 6,000 – 8,000ft



8 Squadron reformed on 8 January 1972 using Shackleton AEW 2s, to provide Airborne Early Warning (AEW).

The Shackelton was retired in 30 June 1991 and 8 Squadron reformed at RAF Waddington with E-3D AWAC aircraft.

Photographed by Mick Bajcar at the International Air Tattoo held at Greenham Common on 28th June 1981. Other pictures are also available from this site.

The label indicates that the maximum operating pressure is 3,300 psi (lbs per square inch). It also mentions “Air” rather than oxygen.

6D.2141 is the old RAF stores Section and Reference Number. The new numbering system called the NATO Stock Number (NSN) is used today. However many of the old items were allocated new NSN.

The current information is as follows:

NSN 1660-99-224-3743


Federal Supply Class (FSC):1660 - Aircraft Air Conditioning, Heating, and Pressurizing Equipment

This indicates that the regulator could have been used for either Air or Nitrogen systems. Air systems are used for Aircraft Air Conditioning & Heating. Nitrogen is used for emergency back-up to blow down flaps etc. Oxygen is only used during high level flight and is provided to each member of the crew via a mask.

On some aircraft clean air can also be supplied via the mask.

It is possible that air could have been used to pressurise the waveguide in the radar to prevent arcing at altitude. (Some systems used Nitrogen).

What ever the final use of the system, the principle function of the regulator is to reduce the high pressure gas down to a suitable pressure for use, typically 15 p.s.i, for air.

Crashed Aircraft

For anyone intrested in going to some of the crashsites up and down there are 3 DVD's out from MHAS, which not only contain video footage of the crashsites and Dig's, but alot of information about each of the aircraft, all 3 are for sale on ebay just type in "crashsites" in the search field and it will bring them up, or even contact me for more information, one of the crashsites filmed is a Avro Shackleton that crashed at foolow in Derbyshire, Intresting Stuff.
