SUBJECT
E-33 ALUMINUM REAR SPINNER BULKHEADS
TO:
KITFOX OWNERS WITH SERIAL NUMBERS 2 THROUGH 263, PLUS NUMBERS 278,
279, 280, 281
FROM:
DENNEY AEROCRAFT COMPANY
There
have been several recently reported incidences of cracks appearing in the
rear spinner bulkhead around the E-73 spinner/prop space. In two
instances, the entire spinner assembly has become detached.
We
are currently testing an new thicker bulkhead (1/8”
instead of 1/l6” aluminum material) to replace the old E-33
bulkhead. When satisfactory tests results are achieved with this new E-33A
spinner bulkhead it will be made available at no charge to all KITFOX
owners upon receipt of their old style E-33 bulkhead.
UNTIL
TESTING IS COMPLETED. REMOVE THE E-31 SPINNER CONE BEFORE FURTHER FLIGHT!
After
installing the new spinner, always check the spinner and spinner bulkhead
before each flight as part of your preflight inspection.
