THIS SEAT IS FOR SALE

Jim's mk 7a seat

The seat is from a Phantom FGR Mk 2 and is a Mk 7aType1. It is mechanically 100% complete but the pack does not contain a parachute. It has a full duplex drogue set and all the "software", (packs, pads and straps) are there. The oxygen bottle is in position.

There is no dingy in the PSP, but all the connections from the PSP are there.

Visually the seat is in A1 condition and is a good example of what is becoming a rare seat for collectors.

The front of the 7A. Sorry about the pattern of the chair it's on!

A good view of the harness retraction system

A close up of the LHS. The remote rocket initiator is seen clearly (the green thing on the RHS of pic)

The Manual Overide Handle clearly attatched to the guillotine sear. The switch in front is for adjusting the hight of the seat bucket.

A close up of the oxygen bottle placed in the rear left of the seat(in the kidney area). The tap bit on top next to the contents guage is the recharge cover.

This is the rocket pack pitch control knob. You dial in your weight to get the thrust of the rocket going through the centre of gravity of the seat.

Close up of the remote rocket initiator This is fired as the seat rides up the rails and 72" of wire is payed out of this. On tensioning a sear is withdrawn. (seen to the left top of the unit).

No, its not upside down. Its this way up so the pilot can read it when in the harness. Twist and squeeze to release the harness.

The larger two brass discs are the main gun secondary cartridges. Scale is inches and centimeters.

The back of the seat with the ejection gun removed The green thing in the middle is the seat hight jack. Note the rear of the rocket pack at bottom of pic.

The cable coming from the silver disk is the cable which is attatched to the drogue gun trip rod and after the seat has risen 72" withdraws a sear to fire the remote rocket pack initiator unit.The tube with the yellow label is the gas tube to the rocket pack.

Secondary crtridge shown fitted in its pocket on the main ejection gun. There are two of these. The cover has been removed.

Secondary charge pocket with the cartridge removed. You can make out the inner ejection gun tube through the gas transfer port (hole)

Main ejection gun from the Mk7a. The crossbeam is used as the connection point for the trip rods and activateds the emergency oxygen on ejection.

The Manual over-ride handle showing its connection to the guilotine sear. On pulling this it releases all the restraints on the "software" and fires a charge to cut the drougue lines to the main parachute. The pilot then pulls the ripcord on his left riser to deploy the main chute.

The undereseat rocket pack. The initiator unit has the red label on it (3rd from left). You can clearly see the gas pipe from the remote firing unit. The gas fires a seperate initiator cartridge to ignite the rocket pack.The leg guards have been removed from the front of the long tubes for clarity. Note the rocket nozzles at either end of the manifold.

A pic of the rocket pack initiator unit with gas tube attatched. The brown bands near the manifold show that the unit contains explosive (not on this one). The nozzles would have "blow out discs" on them on a live seat to stop bits and damp going into the unit and to maintain its integrity.

The RHS leg guard fitted to the rocket pack. Note a long extension to cover the initiator breech with warning label attatched.

Both leg guards fitted to rocket pack These give some protection to the back of the pilots legs on being drawn back by the leg restraint cords on ejection. You can see the mica thermal resistant plates on the front of the guards

Close up of the RHS leg guard. Note extension plate over rocket initiator.
