Can anybody help me out with infomation on folding the blades on a Gazelle?
1. how long a job is it
2. is it a 1/2 man job
3. any special kit needed
A1: If you are practised and know what you are doing, I'd say 10/15 mins.
A2: One on the decking [balancing straddle the engine], one on a short ladder at the blade tip [you may need to raise a tad to loosen up the pressure on the pins] and one to assist with the cradle.
A3: 3 blocks, boom cradle, soft faced hammer [persuader].
The reason I ask is for access in & out of a hangar
You have a problem here in that with the blades folded the tail of the aircraft is very heavy and will crash to the ground if not held very securely when jacking up. It is heavy enough to be too much to hold by one person unless you have a bod counter balancing by standing on the front of the skid just forward of the front skid post. This means you have to have at least 4 people to do it safely and effectively.
Used to have to do this back in the late 70's early 80's and smashed more than one frangible. If you are contemplating this option simply as an easy in/out of a hangar then in my experience - it certainly is not. I'd recommend an alternative. However it is some time since I was last playful with the Gaz so my memory might be a bit jaded. However, I will ask a buddy of mine who is at least current.
There is also the aspect of accidental damage during the process........
Hope that is of help.
Best Wishes
