It is interesting to note it was already a known problem with the engine and was still in the process of being addresses by RR, it was eventually decided that every tappet has to be checked by a Snr NCO(was there ever an engineering fix?). I believe the fire was made worse on the Halifax by the a awkward placing of the fuel shut off valves and a delay in shutting them off
Curiously the photo in Alexander's book on page 308 titled: "Tappets being adjusted on the starboard outer engine of a Halifax MkII in the summer of 1942." shows a mechanic sitting stride an engine and holding a couple of small open ended spanners rather than tappet tool 5034. The tool replies on the experience of the mechanic but the spanners in the photo look totally inadequate for any job on the engine.
