Following an incident back in August we have identified that one of the contributory factors was that the wing the pilot was flying had not been serviced in 350 hours over 8 years of flying. It is very likely that the trimming and brake line lengths were out of certification.
Please, please, please get your kit regularly serviced.
When we are out of the Covid restrictions we are planning on running a workshop to help you check your own line lengths in between services. In the mean time keep safe.
