Byron,
Good point. Since taking his training, I now apply Gena Elfimov's belly whack technique
to all aerobatic planes I fly. Just a couple of weeks ago I found a fuel
gauge in the tail of our Decathlon after someone else had flown it. Foreign
objects are common, according to my A&P, so much so that there has developed
a kind of informal A&P property law of found objects. They get to keep them.
In various planes I've had over the years, besides the fuel guage, I've found
vice grips (in a Cessna I bought), and and AN bolt that had been riding on an
aileron pulley in a Citabria. It was from a wing painting jig (we knew because
it had many, many coats of paint) and had been in the wing root since the aircraft
was new. More experienced aerobatic hands than I also recommend periodically
pulling the inspection panels and looking, both for foreign objects and any
stress damage or other problems. It seems a good idea.
Re controls locking, I can recommend Rich Stowell's emergency maneuver training
(see www.richstowell.com), in which, among other things, he teaches recoveries
from locked controls. Rich's school is in Santa Paula, CA, but he also does
clinics all over. The recoveries are simple enough, but only if you think of them
and can apply them. His course gets recovery techniques for all sorts of emergencies
(upright and inverted regular and flat spins, upsets, etc.) ingrained
in you.

--> Yak-List message posted by: ByronMFox@aol.com
If you have not had the opportunity to read Alan Cockrell's "Yak 52
Close
Call" in the fourth quarter addition of the Warbird Flyer, don't miss
it.
Alan had a unsuspected lost pair of visegrips jam his elevator bell
crank
resulting in a terrifying incident. His experience has brought a couple
of
things to mind. First, in his Yak 52 transition training, Gennady
Elfimov
requires trainees to empty their pockets before every flight and also
slaps
the bottom of the aircraft fore to aft listening for the clanking of
anything
that may have fallen into the belly. ( I confess that I've been doing
neither.) Second, I recall reading an air safety article about using
elevator
trim in the event of a jammed elevator. Alan didn't indicate in the
article
whether or not he tried the idea.
Many thanks, Alan. ...Blitz

I was remiss in not mentioning elevator trim in the article. I trimmed the elevator
full nose-up after the dive recovery and it was of no help.

Most trim tabs function as servo tabs with the smaller trim tab serving to
deflect the elevator in desired direction; e.g. if one desires to trim the
nose of the airplane up one wants to deflect the trailing edge of the
elevator up so the trailing edge of the trim tab must move down.
If the elevator becomes truly jammed, it becomes an extension of the
horizontal stabilizer. Now the trim tab changes function from a trim tab
to a very small elevator attached to a huge horizontal stabilizer. In this
case the sense of the trim tab is *reversed*. Now in order to cause the
nose to come up (if it can at all) you need to deflect the trim tab in what
was the *down* direction.
Remember, this is true only if the elevator is *jammed* and cannot move at
all. If the problem is a broken elevator control cable and the elevator
can still move, the sense of the trim tab is normal.
Of course all of us will take time to think this through as the nose falls
through about 50 degrees nose-down. Just clear your mind and think it
through for just a couple of minutes and you will have no problems
remembering this.

Speaking of close calls..................
I was making an ordinary landing at WJF and after touch down noticed my
RPM would not come all the way down. There was enough power being
produced that it would have made stopping difficult. I applied full
power and went around the pattern again. The next landing was perfectly
normal.....I was able to get RPM down enough to make a normal stop.
I looked at the throttle cable and there is no problem with it. I'm
perplexed as to what may have cause it. Anyone got any ideas?

Thought you guys might get a kick out of this picture..
http://home.earthlink.net/~yak52driver/FIREBOMB.JPG
ALSO........since it's a slow weekend I've decided to share the
following. It isn't aircraft related so delete if your not interested.
But it is special as it relates to all our friends!
Too Busy for a friend?
One day a teacher asked her students to list the names of the other
students in the room on two sheets of paper, leaving a space between
each name. Then she told them to think of the nicest thing they could
say about each of their classmates and write it down. It took the
remainder of the class period to finish their assignment, and as the
students left the room, each one handed in the papers. That Saturday,
the teacher wrote down the name of each student on a separate sheet of
paper, and listed what everyone else had said about that individual.
On Monday she gave each student his or her list. Before long, the entire
class was smiling. "Really?" she heard whispered. "I never knew that I
meant anything to anyone!" and, "I didn't know others liked me so much."
were most of the comments. No one ever mentioned those papers in class
again. She never knew if they discussed them after class or with their
parents, but it didn't matter. The exercise had accomplished its
purpose. The students were happy with themselves and one another.
That group of students moved on. Several years later, one of the
students was killed in Vietnam and his teacher attended the funeral of
that special student. She had never seen a serviceman in a military
coffin before. He looked so handsome, so mature. The church was packed
with his friends. One by one those who loved him took a last walk by the
coffin. The teacher was the last one to bless the coffin.
As she stood there, one of the soldiers who acted as pallbearer came up
to her. "Were you Mark's math teacher?" he asked. She nodded: "yes."
Then he said: "Mark talked about you a lot." After the funeral, most of
Mark's former classmates went together to a luncheon. Mark's mother and
father were there, obviously waiting to speak with his teacher. "We want
to show you something," his father said, taking a wallet out of his
pocket. "They found this on Mark when he was killed. We thought you
might recognize it."
Opening the billfold, he carefully removed two worn pieces of notebook
paper that had obviously been taped, folded and refolded many times. The
teacher knew without looking that the papers were the ones on which she
had listed all the good things each of Mark's classmates had said about
him. "Thank you so much for doing that," Mark's mother said. "As you
can see, Mark treasured it."
All of Mark's former classmates started to gather around. Charlie smiled
rather sheepishly and said, "I still have my list. It's in the top
drawer of my desk at home."
Chuck's wife said, "Chuck asked me to put his in our wedding album." "I
have mine too," Marilyn said. "It's in my diary."
Then Vicki, another classmate, reached into her pocketbook, took out her
wallet and showed her worn and frazzled list to the group. "I carry this
with me at all times", Vicki said and without batting an eyelash, she
continued: "I think we all saved our lists."
That's when the teacher finally sat down and cried. She cried for Mark
and for all his friends who would never see him again. The density of
people in society is so thick that we forget that life will end one day.
And we don't know when that one day will be. So please, tell the people
you love and care for, that they are special and important.

The weather in the California high desert is not conducive to carb
ice. Also, isn't the fuel spraybar downstream of the throttle plate in a
pressure carb?

No mixture on the M-14P engine, I'd look at linkage, from carb to aft
cockpit, both throttle and prop.

I heard it had been raining is CA. <GRIN>
If not carb ice, you might have sucked in something or something fell off
and held the butterfly open. Could even had something that jammed the
external control.
Check as there might be something loose.
