No. 7 Tank Dry Bays
4.13
4.14
The aircraft’s No. 7 Tank Dry Bays are located immediately in front of each of the forward faces of the port
and starboard No. 7 fuel tanks, adjacent to the aileron bay, and underneath the after end of each wing root.
(see Figure 4.3).
Figure 4.3: Location of No. 7 Tank Dry Bay
The No. 7 Tank Dry Bays house the wing rear spar-to-fuselage attachment points and a considerable number of
fuel and other systems in close proximity to each other:
Running fore-to-aft in the starboard Dry Bay are:
the No. 7 fuel tank feed pipe;
the Nos. 6 and 7 tank de-fuel pipes;
the Nos. 6 and 7 tank vent pipe;
the tail anti-ice duct; and
the numerous hydraulic pipes (primarily fore to aft).
Running across and between these pipes is:
the Cross-Feed/SCP duct.
Starboard No. 7 Tank Dry Bay on MR2

Starboard No. 7 Tank Dry Bay
Port No. 7 Tank Dry Bay
Forward
The starboard No. 7 Tank Dry Bay on all MR1s was modified, on conversion to MR2, to house the SCP bleed-air
duct. The SCP duct was routed from the five-way junction on the Cross-Feed duct into and through the bottom
of No. 7 Tank Dry Bay and then to an elbow joint outside the existing line of the fuselage. For this purpose,
a special fuselage fairing was fashioned, the forward element of which was attached to the internally-ribbed
horizontal panel, which formed the lower access panel to the No. 7 Tank Dry Bay (see Figures 4.4 and 4.5).
