2014-22151 Airworthiness Directives; Bombardier, Inc. Airplanes Proposed Rule We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This proposed AD was prompted by a report of an aft equipment bay fire due to chafing and subsequent arcing of the integrated drive generator (IDG) power cables. Additionally, we have received several reports of broken support brackets of the hydraulic lines. This proposed AD would require a one-time inspection of the IDG power cables for chafing, and for any cracked or broken support bracket of the hydraulic line; and corrective actions if necessary. We are proposing this AD to detect and correct broken support brackets of the hydraulic lines, which could result in inadequate clearance between the IDG power cables and hydraulic lines and chafing of the IDG power cables, and consequent high energy arcing and an uncontrolled fire in the aft equipment bay. 2014-09-17 2014 9 https://www.federalregister.gov/documents/2014/09/17/2014-22151/airworthiness-directives-bombardier-inc-airplanes https://www.govinfo.gov/content/pkg/FR-2014-09-17/pdf/2014-22151.pdf Transportation Department; Federal Aviation Administration 492,159 We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc.
