Résumé
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 95-13-04 that was sent previously to all known U.S. owners and operators of certain Bombardier Model CL- 600-2B19 (Regional Jet Series 100) series airplanes by individual letters. This AD requires a revision to the Airplane Flight Manual to prohibit the use of mach trim and to add speed restrictions if the autopilot is disengaged or inoperative. This AD also requires installation of an associated placard. This amendment is prompted by deficiencies that were discovered during a recent review of vendor documentation of the horizontal stabilizer trim control unit. The actions specified by this AD are intended to prevent such deficiencies, which could result in a nose-up trim runaway when a single component in the mach trim circuits fails.
