Trolley Acc's
Trolley Acc's
Shawbury...late 70's, bright sunny morning, Whirlwind Line:
Scene setting:
1. All Whirlwind instructor pilots think they are still SAR/SF and 'volunteer' for aircraft incidents and accidents in the midlands
2. 1st starts of the day require Trolley Acc support, cos ac batteries in those days were no better than car batteries.
3. There is no 3...
4. during this period rotor blades were being inspected for delamination using the highly developed 'acoustic reaction' method...aka, tapping a 10p piece on the blades surface to see if there was any dull thuds
So, we're relaxing in the crewroom when one of the hangar Cpl's wheels a staging over to one of the kites on the line, locks it in place and climbs up to start tapping the blades.
Soon after watching this palaver, one of the jockeys runs in and says "SAR Start on Whisky NOW! Line SNEC say's "Rigga, you do it, RUN!"
So Rigga runs...The crew turn up too, walking fast-ish, and jump into their places. the Trolley Acc is plugged in and waiting for their signal to power up.
Trolley Acc goes on - and a few hand signals later, they say to switch off and unplug, which I do with my normal speed and efficiency, pushing the Acc out of the rotor circle and dropping the Brake as I release it....but it doesn't Brake...and continues rolling slowly away from me, toward other helicopters. I still have to see this SAR start off, so I can't leave....Eeek!
Eventually, I get the dismissal and I start running. the Acc is about 60 yards away - but it seems miles to go after it. It's rolling toward the nose of another Whirlwind and it looks like its going to hit it...WOW! it doesn't hit it, but it disappears behind the nose and doesn't appear as expected in the other side (what the...?) The Whirly shudders....?
I'm still running like the clappers...I round the nose of the Whirly and I see...the hangar Cpl - hanging on to the Blade he was working on - with the Staging about 4 ft behind him!
OOPS! doesn't cover the next statements....
