NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Review the manufacturing processes and continued airworthiness requirements for blades manufactured by companies other than Robinson Helicopter Corporation, and, for those using adhesive bonding, determine if sufficient durability testing and inspections of adhesive bonds are in place to ensure the safe operation of the blades without failure throughout their designed life expectancy in all environmental and operating load spectrums that the blades will experience.
In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to review manufacturing and continued airworthiness requirements for blades made by companies other than Robinson Helicopter Corporation, specifically those using adhesive bonding. The review should determine whether adequate durability testing and inspections of adhesive bonds exist to guarantee the blades' safe operation throughout their designed lifespan under all expected environmental and load conditions.
