 |
|
Hi Richard and all,
Thanks for the question.
The throttle lever on my Firestar II with 460 hours broke just above
where it is welded to the tab. I have submitted a picture of the broken
part to fileshare so those who have Firestar aircraft with similar
throttle levers can see the break to know where they might want to
inspect. Fortunately for me, the lever broke while I was on the ground
because I would not have been able to change the throttle setting had I
been airbourne. The break occurred as I was opening the throttle and it
occurred on a single push with no prior warning.
Picture reference below.

Was the aftermath of the flight more interesting than usual?
Or just more challenging?

Vince:
Some years ago I developed a low tech night landing system for my grass
strip. It worked great. I could put the mkIII down right on the money
every time.
One pitch black dark night I came sailing back home from the local airport.
Lined up on my reflectors on final. Pulled back the power and felt the
throttle lever give. It had seperated at the flange and bent backwards.
Throttle was to fast for landing on my short strip, and not enough power to
climb back out through the slot and turn in the trees. I quickly reached
down between the seats and was able to twist the flange and open the
throttle a tad more, enough to get the mkIII to climb. Had Murphy been on
the ball, he would have my single landing light burn out at the same time.
I flew back to 08A, shut down the engine, and dead sticked a good landing.
A couple of my buddies were still at the airport. They were wondering what
the Hell Hauck was doing out on the runway. All they could hear was the
engine rev up and shut down, as I maneuvered my way to the FBO to tie down
for the night.
Early on Old Kolb used 1/4" 4130 tubing for the throttle lever. After a few
breaking, they changed over to 1/4" solid steel rod. Have not had a
throttle problem in many years.
Also, I don't shoot night landings into Gantt International Airport anymore.
 Don't fly at night unless it is absolutely necessary.

The throttle lever on my firestar did the same thing in flight after only 80 hours. I was able to change throttle settings by turning the hub. I made a temporary field repair using JB weld and a 3/16" drill bit as a connecting rod. That was 40 hours ago and I see no real need to change it.
Mine broke off without bending as yours did. If you look at the missing paint at your bend, it looks to be corroded like it had been bent for a while?
