| 00-10670 | Airworthiness Directives; Boeing Model 737-100, -200, -300, -400, and -500 Series Airplanes | Proposed Rule | This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Boeing Model 737- 100, -200, -300, -400, and -500 series airplanes. That AD currently requires inspection of the fueling float switch wiring in the center fuel tank to detect discrepancies, accomplishment of corrective actions, and installation of double Teflon sleeving over the wiring of the float switch. In lieu of the above mentioned requirements, that AD provides for deactivation of the float switch. This proposed action would eliminate the option for deactivation of the float switch and require, for all affected airplanes, repetitive inspections of the float switch wiring to detect discrepancies; replacement of the float switch and wiring, if necessary; and replacement of the double Teflon sleeving. For certain airplanes, this action also would add a new requirement for inspection and installation of partial double Teflon sleeving in a certain area. The actions specified by the proposed AD are intended to detect and correct chafing of the direct current powered float switch wiring insulation in the center fuel tank and the resultant arcing from the wiring to the in-tank conduit, which could present an ignition source inside the fuel tank and result in a consequent fire or explosion. | 2000-04-28 | 2000 | 4 | https://www.federalregister.gov/documents/2000/04/28/00-10670/airworthiness-directives-boeing-model-737-100--200--300--400-and--500-series-airplanes | https://www.govinfo.gov/content/pkg/FR-2000-04-28/pdf/00-10670.pdf | Transportation Department; Federal Aviation Administration | 492,159 | This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain Boeing Model 737- 100, -200, -300, -400, and -500 series airplanes.
