## Summary

We are revising an earlier proposed airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -700C, -800, and -900 series airplanes. That NPRM proposed to require inspecting the orientation of both sides of the coil cord connector keyways of the number 2 windows on the flight deck; re-clocking the connector keyways to 12 o'clock, if necessary; and replacing the coil cord assemblies on both number 2 windows on the flight deck. That NPRM was prompted by reports of arcing and smoke at the left number 2 window in the flight deck. This action revises that NPRM by changing the keyway position of certain receptacle connectors and adding airplanes to the applicability. We are proposing this supplemental NPRM (SNPRM) to prevent arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the flightcrew. Since these actions impose an additional burden over that proposed in the NPRM, we are reopening the comment period to allowthe public the chance to comment on these proposed changes.
