Gatwick Aviation Museum History
This T7B Hunter
arrived in pieces in early 2002 and was re-assembled in July 2002.
Since its arrival a number of remedial actions have been taken to repair
some flying controls and other internal systems. The missing panels
have been sourced and will be fitted when they arrive. A full survey
of the airframe has been carried out to determine what work is needed.
The search for a suitable engine has been successful with a low houred
Avon 122 being purchased. A jet pipe has also been acquired. Work on
fitting these items will begin in 2009. In late 2007 the aircraft was moved closer to the museum workshop to enable more intensive work
to be carried out.
Update 12/2007. Work has finally begun on returning 591 to a live state. In recent weeks work has forged ahead. The hydraulic system has been refurbished and completed. The system is now full and bled, enabling the various hydraulic systems to be exercised weekly. The electrical system has also received attention, with ground power being restored. Work will begin in the next few weeks, removing the ejection seats for access to the AC invertors, which need testing and refurbishing.
A re-paint of this Hunter was planned for 2008, unfortunately due to the poor weather at weekends this will now take place in 2009. It will be painted in the white and red scheme it once wore when based at RAF Valley with 4 FTS. Most of the airframe preparation work has been completed and a coat of sealant paint has been applied to the upper surfaces, it is intended that the undersides will be completed before the end of 2008.
A Special thanks must go out to our very generous friends at Hunter Flying Ltd in Exeter. Thank you very much John Sparks for Donating various missing parts for XL591.
Work has also started on cleaning the engine bay out of loose paint and dust, ready for engine fitting in 2009. The engine will be fitted before she is painted. We don't want greasy mitts all over a fresh paint job!
Update January 2009
Ejector seats have been removed and the AC Junction Box removed and refurbished. A lot of work is required on the junction boxes fitted on the floor below the seats, previous water contamination has caused a certain amount of corrosion. The three main controls for the engine, LP cock, HP cock and throttle have been refurbished. The main task was to free up the control run teleflexs'. We still have a hydraulic problem, this willl be sorted out when the weather improves. Some paint in the form of a sealant coat has been applied, mostly to the upper surfaces. Now that the corrosion treatment has been completed on the lower surfaces this to will receive a sealant coat as soon as possible.
Recent work has included the continuing issue with the hydraulics, the various systems have air in them and despite much work are still not free of the air. In conjunction with the hydraulics the inner drop tanks have been added and the outer pylons fitted. Work has begun on the repaint, it was too hot in July for this to be carried out. It is hoped that most of the airframe will receive at least one top coat this year.
Update March 2011
The lower parts of the fuselage and top of the wings received a base coat of grey paint. This sets up the airframe for top coats to be applied. If the weather is kind to us we could have it mostly completed in weeks.
The unseasonal warm settled weather has allowed more work to be carried out on the painting of the T7. The fuselage has had the white coat applied and the red spine has had a first coat. The wing root area has also had a first grey coat. Removal panels on the lower part of the fuselage have also been painted red, once the main lower area is completed they will be refitted.
The last picture was taken on the 8th of October 2011, the last of the paint for that year had just been applied. Hopefully we will get another spell of warm settled weather in early 2012 that will allow the paint job to be completed.
