Sicherheitsempfehlungen
NTSB issued 1 Safety Recommendation
Issued: 12-JAN-1967 | To: | A-67-3 |
IT IS RECOMMENDED THAT ALL USERS OF CONVAIR 340, 440 AND 580 MODELS BE ALERTED TO THIS VARIATION IN ELECTRICAL COCKPIT HEATERS, THAT THE TERMINALS BE PROMINENTLY IDENTIFIED AND MANUAL INSTRUCTIONS CITE THE DIFFERENT TERMINAL CONFIGURATIONS WITH APPROPRIATE INSTALLATION INSTRUCTIONS. IT IS RECOMMENDED THAT THE CONVAIR 340, 440 AND 580 AIRCRAFT HEATER CIRCUITS BE MODIFIED TO PROVIDE CIRCUIT PROTECTION THAT WILL OPEN UNDER THE MOST ADVERSE FAULT CONDITION BEFORE THE FEEDER LIMITER OPENS. DURING THE INVESTIGATION, TWO MAINTENANCE ITEMS WERE NOTED WHICH WE BELIEVE ARE WORTHY OF YOUR ATTENTION. WHILE EXAMINING THE AIRCRAFT, LOOSE NUTS, SCREWS, DRILL SHAVINGS AND TRASH WERE FOUND INSIDE OF THE CIRCUIT BREAKER PANEL COMPARTMENT. ALSO, IT WAS REVEALED THAT NO FUNCTIONAL TESTS WERE PERFORMED ON THE HEATER AFTER ITS INSTALLATION BEFORE RELEASING THE AIRCRAFT FOR PASSENGER SERVICE. (Closed - Acceptable Action) |
