## Summary

We are revising an earlier proposed airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE- FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The NPRM proposed to require modification of the anti-collision light bonding. The NPRM was prompted by a report of an in-flight lightning strike to the WHELEN anti-collision light located on the top of the vertical fin tip that caused severe damage and resulted in the loss of some airplane functions. This action revises the NPRM by clarifying the applicability. We are proposing this supplemental NPRM (SNPRM) to prevent loss of electrical power and essential airplane functions, and possible reduced control of the airplane. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
