We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by reports of two cases where the main landing gear (MLG) failed to fully extend; it was determined that interference between the MLG door and the MLG fairing seal prevented the MLG door from opening fully. This proposed AD would require repetitive detailed inspections of the MLG fairing, fairing seal, door, and adjacent structures; and replacement or repair of affected parts and fasteners, or removal of the door, if necessary. This proposed AD would also require installation of a safety guide in the MLG fairing and an increase of the spacing between the MLG door and the fairing, which would terminate the repetitive inspections. We are proposing this AD to detect and correct interference between the MLG door and the MLG fairing seal. Such interference could result in a MLG failing to fully extend, which could cause an unsafe asymmetric landing configuration.
