## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-9 airplanes. This AD was prompted by a report of missing sealant on the left and right wing leading edge outboard blowout door. This AD requires doing a fluid seal contact inspection and a detailed inspection for missing sealant on each blowout door and applying sealant if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
