Airworthiness Directive · Amendment 39-19005 · Landing gear
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes, certificated in any category, serial numbers 19001 through 19039 inclusive.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports of failures of the landing gear alternate-extension system. This AD requires replacement of certain nose landing gear and main landing gear electro-mechanical actuators. We are issuing this AD to address the unsafe condition on these products.
Within 1,200 flight hours or 12 months after the effective date of this AD, whichever occurs first: Replace the nose landing gear (NLG) and main landing gear (MLG) electro-mechanical actuators (EMAs) having part numbers (P/Ns) BA698-85006-1 and BA698-85007-1 with P/Ns BA698-85006-3 and BA698-85007-3, as applicable, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 670BA-32-047, Revision A, dated December 5, 2016 (“670BA-32-047, Revision A”). Where 670BA-32-047, Revision A, instructs operators to contact Bombardier if it is not possible to complete all the instructions in 670BA-32-047, Revision A, because of the configuration of the airplane, this AD requires that any deviation from the instructions provided in 670BA-32-047, Revision A, must be approved as an alternative method of compliance (AMOC) under the provisions of paragraph (j)(1) of this AD.
