Glasgow Helicopter Crash

[Julius Geezer]

If the gearbox seizes and stops turning, or if the shaft is broken and stops turning, the head won't turn.

Some good info , cheers , a lad I used to know was in the forces and ended up in the Army Air Corps and he used to go on about a filter in the rotor head that picks up metal shavings in the gearbox to stop it siezing up , always remember him saying how this filter has to be changed every few hours of operation and if not then it can be catastrophic , is this right ?

I believe so, yes. It wasn't my trade like but I think that's been the cause of a few crashes in the past.

But if something stopped working wouldn't they have immediately made a mayday call?

No, if something stops working, you fall from the sky like a piano with an anvil tied to it.

Still would have taken a minute or so wouldn't it? Obv depending on how high they were.

1. Fly the airplane (aircraft)
2. Take corrective action
3. Tell everyone else about what's going on when you can be arsed to use the radios

At least, that's how I was taught

Are kid works as an engineer for Bond helicopters who leased the helicopter to the Bizzees,he's based in Blackpool though and has never worked on this helicopter.He's not speculated what he thinks caused this, he has In the past worked on helicopters that have been involved in tragic accidents but they have been put down to pilot error.

Pan pan pan first ?

Never flew for an airline, and each may do it differently, but generally you fix the problem first. There is a well-done simulation (with radio calls) of the US Air crash into the Hudson that is a great tutorial on emergency management. I'm not saying you wouldn't talk first (you see that Sullenberger talks early), but you see the external talking reduce as the workload increases. The full transcript shows the two-pilot crew doing lots of talking/work, but very little information goes outbound (looking for a good link).

If this helo pilot, working alone at just a few hundred feet, had an emergency that required prompt attention I don't expect he would rush to get on the radio.

**Check out this video of Cactus 1549, which has CVR overlay with external audio. Lots of business going on with the two pilots, very little chatter to the outside. HOT1 and HOT2 are the two pilot microphones on the CVR. The other notes are other sounds, beeps, etc, from the recorder.

Yep, it usually depends on the severity of the problem, in the case of Cactus 1549 the problem as about as severe as a pilot can face so the priority was on attempting to fix the problem, whereas in a less severe case like the video below, they usually let ATC know immediately.

If the rotors weren't rotating on the helicopter when it crashed, I doubt very much the pilot had time to do anything, never mind notify ATC.
