Federal Aviation Administration January 11, 2010 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Boeing Model 737-600, -700, -700C, -800, -900, and -900ER Series Airplanes
Document Number: 2010-187
Type: Proposed Rule
Date: 2010-01-11
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Boeing Model 737-600, -700, -700C, - 800, -900, and -900ER series airplanes. The existing AD currently requires repetitive detailed inspections of the slat track downstop assemblies to verify that proper hardware is installed, one-time torquing of the nut and bolt, and corrective actions if necessary. This proposed AD would also require replacing the hardware of the down stop assembly with new hardware of the down stop assembly, doing a detailed inspection or a borescope inspection of the slat cans on each wing and the lower rail of the slat main tracks for debris, replacing the bolts of the aft side guide with new bolts, and removing any debris found in the slat can. This proposed AD also would remove airplanes from the applicability. This proposed AD results from reports of parts coming off the main slat track downstop assemblies. We are proposing this AD to prevent loose or missing parts from the main slat track downstop assemblies from falling into the slat can and causing a puncture, which could result in a fuel leak and consequent fire.
