I have just found my first problem with my Tecnam P92 echo super after 3 years and just over 200 hours. opon aplying the breaks and turning the little tap (same as fuel tap) between the seats to lock the brakes on as in hand break,
I found it not holding. so on consulting my trusty mechanic, we purchased a new hand break tap, this did not remedy the problem, the next was to bleed the whole system No joy.next was to trace the break system and behind the seats found a one way valve that we pulled apart and found a broken O ring, this little valve has the smallest O ring i have ever seen it would just fit over the end of a match. Problem Solverd
Cheers TecnamDave
