AD NUMBER: 2007-23-15
SUBJECT: Airworthiness Directive 2007-23-15 SUMMARY: We are adopting a
new airworthiness directive (AD) for the products listed above.
This AD results from mandatory continuing airworthiness information
(MCAI) issued 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 found the
occurrence of incorrect use of the selfl ockingnuts in bolts
subject to rotational loads in bolted fittings of some assemblies
of met alliccomponents. Such event may result in disconnection of
those fittings, which jeopardizes the structural integrity of the
aircraft or its flight controls. Since this condition may occur in
other airplanes of the same type and affects flight safety, a
corrective action is required. Thus, sufficient reason exists to
request compliance with this AD in the indicated time limit. We are
issuing this AD to require actions to correct the unsafe condition
on these products.
