Airworthiness Directive · Amendment 39-8791 · Bombardier Inc. Airplanes
Bombardier Inc. Airplanes
Superseded. A later AD replaced this one: AD 94-24-02. Comply with the one in force.
This AD applies to Bombardier Inc. CL-600-2B19 (Regional Jet Series 100).
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to Canadair Model CL-600-2B19 "Regional Jet" Series 100 airplanes. This action requires a revision to the Airplane Flight Manual (AFM) to limit altitude and airspeed operations of the airplane under certain conditions of hydraulic system failure. This amendment is prompted by a report of sheared- off shear pins found on one airplane's elevator dampers. The actions specified in this AD are intended to prevent undampened vibration of the elevators in normal cruise conditions when combined with hydraulic system failures, a condition which could result in reduced controllability of the airplane.
