Background: | A recent incident has been reported where the right hand power lever jammed in the flight-idle position during the landing roll-out on a Model 328-100 aircraft. The aircraft was stopped by excessive braking. Investigation revealed that the cockpit door locking device had fallen off the right hand side of the cockpit wall and blocked the right hand power/condition lever pulley/cable cluster below the door. This Directive requires a one-time inspection of the cockpit door locking device and the surrounding area and the reporting of all findings to the Type Certificate holder. This is considered interim action and the retrofit of a new design may be implemented later. |
