NTSB Safety Recommendation — Aviation
Recommendation text
1. THAT APPROPRIATE ACTION BE TAKEN TO REQUIRE THAT ALL BEECHCRAFT MODEL 18 AIRCRAFT LANDING GEAR ASSEMBLIES BE INSPECTED FOR THE PRESENCE OF FATIGUE CRACKS ON THE UPPER SLIDE TUBE FITTING IN THE AREA OF ITS ATTACHMENT TO THE SLIDE TUBE. 2. THAT THE UPPER CHAIN IDLER SPROCKET BEARINGS BE CHECKED FOR RESISTANCE TO ROTATION AND, IF NECESSARY, CLEANED OR REPLACED. 3. THAT RECURRENT INSPECTIONS BE REQUIRED UNTIL SUITABLE CORRECTIVE MODIFICATIONS ARE MADE.
In plain language (FlightFinder summary)
The FAA is directed to mandate inspections of Beechcraft Model 18 landing gear for fatigue cracks on specific upper slide tube fittings and to check or replace upper chain idler sprocket bearings that do not rotate freely. These checks must be repeated regularly until permanent modifications can be implemented to address these potential mechanical failures.
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.
