landing gear transition on takeoff

[Rmp]

Hi all I would like to explain a problem and after sometime how I over come this
Problem.
My undercarriage would retract up light would come on for moment then off. Rear doors would be partially open.
Would check fluid level and might be bit low, top up and bleed system. All would be well for a while then same thing this went on and off for couple of years. But each time we jacked plane and tested all worked fine.
The problem turned out to be the left rear up switch not adjusted correctly but close enough that if you tested it it would mega as a closed switch.
Only in flight would the switch not close and only occasionally.
Hope this helps anyone with similar problem in the future.
