The "hard lines" in all the Commanders are becoming the number one hyd iss
ue. Inspect all of them and dont kid yourself. If they have any corrosio
n, change them out.
ALSO!!You landed with no brakes or steering and pulled it off, good on you
! It is not necessary do that. PLEASE, PLEASE EVERYONE, LISTEN UP. AS SO
ON AS THE ENGINS ARE RUNNING PULL THE AUX HYD CIRCUIT BREAKER. DOING THIS
ASSURES THAT THERE WILL BE ENOUGH FLUID FOR BRAKES AND STEERING. PLEASE,
LETS STOP BEING STUBBORN ABOUT THIS BEFORE ANOTHER AIRPLANE IS LOST!! Th
anks and good job with the landing!! jb

Subject: AC-680FLP Hydraulic line problems
Hello,
Had a small hydraulic line in the left wheel well break a while back. Had
to land with no brakes, flaps, or steering. Got that fixed. Flew plane
to the A&P location for an annual. Test flight after the annual, hydraul
ic leak in either the up or down line to the right main gear, actual line
hasn't been isolated yet. My question...both hydraulic lines, on differe
nt side of the plane (comletely different lines also) have broken within
2 hours of flying time. Is there any hydraulic line history or trend for
Commanders whereby hydraulic lines start to fail at the same time. In ot
her words, is this going to be a problem in the next hours of flight or ne
xt years of flight. Does anyone have experience here?
Had to have new engine mounts and wastegates replaced during the annual.
Paul Gendron in Ft Lauderdale, FL did a good job with the work. Corrosi
on on the mounts and manual wastegates were out of shape and quite thin at
the elbows. Plane has been down over 4 months and now this hydraulic li
ne problem.
