crash comic, yeah well don't believe everything that your read in a newspaper they say. although in recent years there seem to be less lapses of the imaginery and ridiculous.
Valve bounce speed will be reached following a freewheel failure. The noise is frightening, the fan throws the belts and i don't know what RPM it is but it definately stopped accelerating before i got the throttle off in a heartbeak or well less. overspeed checks did not yield anything unusual, but in strip down it was a different story.
There was another twist to it which I won't relate.
The rest was is as bellfest says, finger trouble. over 250rpm over usually rewards the engineers with some metal sample at the 75 to 100 hour mark afterwards depending on the power pulled at the time.
i remember being told to go to 3400 and bleed off if I was real stuck, which I was in a 3B2 once. The task was to lift out a crashed 3B1 from high timber at fairly high DA. we did it in two lifts.
on the second trip we loaded the litters and the hook load and left it there while I dropped the gingerbeer at a clearing about half a mile away.
Loaded with the gingerbeer his tool box and the hooked load, ect. I went to 3400 for about two seconds as we climded towards 35.5 (one inch under max for temp correction on the day) inches, and i felt I could feel the metal shredding. I gave that away and bounced it off instead from 3300 and just as we got around the corner the gingerbeer nearly !!!!! himself.
right there only fifty yards from where he was were about ten very curious wild buffalo. we didn't stuff the engine, but oh so close i think.
