The Federal Aviation Administration recently released an Emergency Airworthiness Directive (EAD) to owners and operators of Bombardier, Inc. Model CL-600-2B16 airplanes. The EAD CF-2014-27, issued to correct unsafe conditions on the CL-600-2B16 models, states the following:
“There have been three in-service reports on 604 Variant aeroplanes of a fractured fastener head on the inboard flap hinge-box forward fitting at Wing Station (WS) 76.50, found during routine maintenance inspection. Investigation revealed that the installation of these fasteners on the inboard flap hinge-box forward fittings at WS 76.50 and WS 127.25, on both wings, does not conform to the engineering drawings. Incorrect installation may result in premature failure of the fasteners attaching the inboard flap hinge-box forward fitting… and consequently the detachment of the flap surface. The loss of a flap could adversely affect the continued safe operation of the aeroplane.”
The EAD goes on to mandate a “detailed visual inspection of each inboard flap hinge-box forward fitting, on both wings, to determine if the fasteners are correctly oriented and intact and complete rectification as required.” If any fastener is found fractured, the EAD requires owners and operators of the Bombardier, Inc. Model CL-600-2B16 airplanes to “replace all forward and aft fasteners at WS 76.50 and 127.25 before further flight and within 24 months, if any incorrectly installed fasteners are found.” In addition, if any incorrectly oriented but intact fasteners are found, and no fractured fastener is found, the EAD requires owners and operators to “repeat the visual inspection… at intervals not to exceed 10 flight cycles, until the replacement of all forward and aft fasteners at WS 76.50 and WS 127.25, on both wings have been done.”
