NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIRWORTHINESS DIRECTIVE TO REQUIRE, WITHIN A REASONABLE TIME, A ONE-TIME INSPECTION FOR EVIDENCE OF EXCESSIVE WEAR PITTING CORROSION, AND STRESS CORROSION CRACKING IN THE SWIVEL JOINTS OF BOGIE BEAMS OF ALL MAIN LANDING GEAR OF DC-8 AIRPLANES THAT INCORPORATE A SWIVEL BOGIE BEAM CONFIGURATION. DURING THIS INSPECTION, SPECIAL ATTENTION SHOULD BE GIVEN TO EXAMINATION OF INSIDE DIAMETER SURFACE AND UNPAINTED AREAS OF THE UPPER AND THE LOWER SWIVEL PIN LUGS IN THE FORWARD AND AFT BOGIE BEAMS.
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an airworthiness directive mandating a one-time inspection of swivel joints on bogie beams of DC-8 airplanes with a swivel bogie beam configuration. The inspection should look for excessive wear, pitting corrosion, and stress corrosion cracking, with special emphasis on the inside diameter surfaces and unpainted areas of the upper and lower swivel pin lugs in both forward and aft bogie beams.
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.
