Bloody Electricians
During my sojourn in the RAF as an
aircraft electrician one of the niggling problems that I found was the
"feeling" between engine airframe trades and the "ancillary trades"
radio, electrical instruments , armourers.
The engine/airframe types had
always been the groundcrew in the "good old days" (in their eyes).
you know biplanes, ! puttees and bags of "bull...." After all they were
paid slightly more than us in the then trade structure of the Royal Air
Force and I suspect that they felt rather threatened at the introduction
of ancillaries into squadron life.
One old timer said to me
"These pioneer aircraft are far too complicated electrically , when I
worked on Siskins/ Gamecocks etc. they just had a dynamo with a propeller
on the wing" ( complicated ???? blimey you couldn't find anything more
basic !)
Now as I have mentioned before on 209
squadron in Malaya we were equipped with the incredibly slow Single
Pioneer and its big brother the Twin Pioneer (known as the twinpin)
I remember once there was a
big panic in the squadron, an engine sergeant approached me,,,"Cpl
Shelvey , your bloody fire warning has gone off and caused one of the
twinpins to force land on an emergency airstrip in the ulu!" ALL MY
FAULT OF COURSE !
Perhaps I should explain, the
Alvis Leonades engines of the twinpin were protected by a "firewire"system
.
It was a thin copper capillary tube
about four feet long which was wrapped around the danger spots on the
engine. If the engine overheated it caused the explosive substance
inside the tube to expand and push out a plunger which operated a micro
switch to illuminate a warning light in the cockpit.
Well, that was it, I quickly
put together what I thought was necessary, new firewire system, wiring
lamps and the ubiquitous tool bag, and accompanied by the constantly
bickering whinging sergeant (engines) giving out the same old line "it
must have been an electrical fault"
we set off in another twinpin.
The emergency airstrip was in the
middle of the jungle, in fact you could say that it was in the middle of
nowhere. As we circled overhead I could see the two aircrew (pilot & nav.)
sitting on the ground disconsolately staring up at us. We landed and
approached the two stranded aircrew.
The pilot and navigator
were initially quite friendly, but after having been assured by
this expert engine
sergeant that it was just an electrical fault I noticed that the
atmosphere became distinctly frosty.
I lost no time and was up
the ladder, cowlings off and a quick decco to see what was up.. during
this time I couldn't help noticing that the sergeant had lit the hexamine
stove, opened the compo rations and sitting down comfortably kept up a
scurrilous diatribe about electricians to the assembled officers, He then
settled down to a brew-up ... I of course was not invited !
Well you've guessed it,
it wasn't an electrical fault at all - the electrical warning system had
worked perfectly. In fact one of the exhaust manifolds on top of the
engine had blown off causing hot (very hot) gasses to flow over the
wing. It was a lucky thing that the aircrew had flow
"by the book" cutting
the faulty engine and landing immediately.
As soon as I had informed the
sergeant he spat out his tea and cursed --- he had made the tea with curry
powder !
