NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN EMERGENCY AIRWORTHINESS DIRECTIVE TO REQUIRE THAT ALL P/N VAC 6000K-26 ELEVATOR HORN ASSEMBLIES INSTALLED ON VARGA AIRCRAFT BE INSPECTED BEFORE FURTHER FLIGHT AND THEREAFTER AT APPROPRIATE TIME INTERVALS. HORN ASSEMBLIES SHOULD BE REMOVED FROM THE AIRCRAFT AND THE MOUNTING FLANGE AREAS STRIPPED OF PAINT. THE UPPER AFT CORNERS OF THE CHANNEL BENDS AND THE MOUNTING RADII SHOULD THEN BE INSPECTED BY AN APPROPRIATE NONDESTRUCTIVE TEST METHOD. HORN ASSEMBLIES FOUND CRACKED SHOULD BE REMOVED FROM SERVICE. (URGENT)
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an emergency airworthiness directive requiring immediate and recurring inspections of certain elevator horn assemblies (part number VAC 6000K-26) on Varga aircraft. The assemblies must be removed from the aircraft, the mounting flange areas stripped of paint, and the upper aft corners of the channel bends and mounting radii inspected using an appropriate nondestructive test method. Any cracked assemblies must be removed from service.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
