Aviation accident CHI07FA107

In-flight separation of the left engine thrust reverser translating cowling due to intermittent binding and jamming of the reverser on the accident flight and on previous flights. Contributing factors were the inadequate maintenance action by the operator due to their failure to properly resolve the prior reverser malfunctions, the failure of the pilots of previous flights in not referring earlier reverser deployment failures for maintenance action, and incomplete company/manufacturer's procedures because they did not address anomalous reverser indications during ground operations.
