AD NUMBER: 2007-25-10
MANUFACTURER: Dassault-Aviation
SUBJECT: Airworthiness Directive 2007-25-10
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: A rotating rod in the trailing edge flap control linkage broke in flight. Investigations revealed that the rotating rod had been installed in thewrong side during a maintenance operation.

This incorrect installation caused a contact between the rotating rod and its retaining bracket leading, after some time in operation, to the rodbreakage and flap asymmetry situation. The consequence on the airplane of the flap asymmetry combined with a latent failure of the asymmetry detection system is classified as a catastrophicfailure condition.

The unsafe condition is failure of the rotating rod in the control linkage of thetrailing edge flap and consequent flap asymmetry during the approach to landing, which couldresult in reduced controllability of the airplane.

We are issuing this AD to require actions to correct the unsafe condition on these products.
