I had the first Nickel Leading Edge (NLE) Catto propeller in the UK and it has the back up screws fitted (Dec 2011). It has been a wonderful prop for touring/aeros/operating from grass strips etc being a great compromise of performance, smoothness and quietness.
In July 2013 after being alerted by this forum I observed hairline cracks emanating from the screws. Discussed with Craig and my Inspector and decision was prop was airworthy but Craig offered to replace prop with new NLE design without the screws.
My new prop is being shipped to the UK this week but due to change of pitch and method of securing NLE the UK airworthiness authority has requested various items of information. I have passed part of the request onto Craig but some would be better obtained here.
I would therefore be very grateful if owners of the 2014 design 3 blade prop could post to me some or all of the following data:
1. Engine size
2. Hours on 2014 prop
3. Aeros? Y/N
4. Dual P-Mags? Y/N
5. Comments or issues with NLE
Thanks in advance
