AD NUMBER: 2007-23-04
SUBJECT: Airworthiness Directive 2007-23-04 SUMMARY: We are adopting a
new airworthiness directive (AD) for the products listed above.
This AD results from mandatory continuing airworthiness information
(MCAI) originated by an aviation authority of another country to
identify and correct an unsafe condition on an aviation product.
The MCAI describes the unsafe condition as: It has been discovered
in several cases that clamp bolts of the elevator spring tab
mechanism were not installed in the correct orientation. Bolts have
been found installed with bolt heads on the lower position and in
two cases, some bolts, nuts and washers[hardware] were found to be
loose or missing. Detachment of an elevator spring tab mechanism
clamp bolt could lead to jamming of the elevator control system and
reduced controllability of the aircraft. We are issuing this AD to
require actions to correct the unsafe condition on these
