[Underlined] Rivet[deleted] t [/deleted]ing A.24. + M426 [/underlined]

Rivet[deleted] t [/deleted]ing is being carried out mainly in the fuselage bays, Wing Bay, and spar boom bay.
Steel tubular rivets are used for the jointing of the geodetic panels forming the fuselage, a pneumatic pressing tool being used to bell the ends.
A spot check was taken on fuselage P.G.237 before rive[deleted] t [/deleted]ting and afterwards. The holes were checked for elongation pitch & burrs, and found correct. The assembly was rechecked after rive[deleted] t [/deleted]ting, the belled ends were found to be uniform with no trace of cracks.
Dural rivets are used on the rear fuselage frames, also on the wings and spar booms. A spot check was taken on a Starb Inner Spar Boom No 2725 and found satisfactory.

[Underlined] Heat Treatment Control [/underlined]
Dural rivets are held after normalising in refrigerators at a temp of -5° to -20°C. Freezing elements and unused rivets are changed each morning. The two hourly collections and distributions in coloured tins are working satisfactorily, and only white tins, which was the correct colour for the time of the visit, were to be found. A temp check is taken periodically by M.T.D. but a book record is not kept.
A temp check was taken by me at approx. 4 pm. the reading being -7°C, the element having been put in approx 8.A M. that morning. This is within the required limit of 0° to -5°C for the 45 hour period. As the rivets and elements are changed every 24 hours, this is considered quite satisfactory
Process is considered satisfactory.
