A lot of life's problems can be explained by the military and its
application of common sense.
Don't ever be the first, don't ever be the last, and don't ever volunteer
to do anything.
As you can see the if the filter comes off
the safety wire ONLY holds the filter not the clamp, and WHY did the
filter come off because of a loose clamp!
K & N air filter - safety
advisory.
US Light Aircraft Corporation Model
Hornet - Engine Failure
Incident report:
The engine installed in this aircraft was a "Hirth
Model 2706," and the propeller was a "Tennessee Model 58/46." An abnormal
noise was heard during flight, and the propeller failed. An off airport
landing was made. The aircraft sustained substantial damage.
During an investigation, an engine air cleaner assembly
was discovered to be missing. The submitter speculated that the air
cleaner assembly came loose, struck the propeller, and caused this
failure.
The air cleaner was a "K&N Model," and a part
number was not available. Prior to flight, the engine/propeller components
should be closely inspected for security.
Part total time-96 hours.
Suggestion: K & N airfilters supplied for
AIRCRAFT use have tabs built into the filter for connecting the airfilter
to the carburetor using safety wire.
It is necessary to drill the small flat
plate on the rear of the Bing 54 carb to allow insertion of the safety
wire.
When safety wiring the air filter
run the safety wire down under the hose clamp and then in through
the hole in the back of the carb.
The above photo shows the suggested way to safety
wire the airfilter. Note that the owner has also run safety wire to
the chrome airfilter cover plane, which has been reported to come
off filters from aircraft while in flight.
The new K & N airfilters do not have the
chrome cover as it can separate from the filter, and the new filters
(photo above) have tabs for connecting the safety wire to the air
filter.
Note in the picture above the air filter has the tab, the
Bing Carburator the hole, but the owner has NOT installed the safety wire!
