## Summary

We propose to adopt a new airworthiness directive (AD) for certain DASSAULT AVIATION Model MYSTERE-FALCON 900 and FALCON 900EX airplanes. This proposed AD was prompted by reports of chafing between the tail strobe power supply and a hydraulic line. This proposed AD would require modifying the tail strobe power supply wire routing. We are proposing this AD to prevent chafing between the tail strobe power supply and a hydraulic line, which could result in hydraulic fluid leakage and possible fire due to arcing, and consequent loss of control of the airplane due to structural failure of the tail.
