NTSB Safety Recommendation — Aviation

Recommendation text

THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THAT ALL TURBOJECT TRANSPORT CATEGORY AIRPLANES CERTIFICATED IN THE FUTURE, RECEIVE FULL SCALE STRUCTURAL FATIGUE TESTING TO A MINIMUM OF TWO TIMES THE PROJECTED ECONOMIC SERVICE LIFE. ALSO REQUIRE THAT ALL CURRENTLY CERTIFICATED TURBOJECT TRANSPORT CATEGORY AIRPLANES THAT HAVE NOT BEEN FATIGUE TESTED TO TWO LIFETIMES, BE SUBJECTED TO SUCH TESTING. AS A RESULT OF THIS TESTING AND SUBSEQUENT INSPECTION AND ANALYSIS, REQUIRE MANUFACTURERS TO IDENTIFY STRUCTURE SUSCEPTIBLE TO MULTIPLE SITE DAMAGE AND ADOPT INSPECTION PROGRAMS APPROPRIATE FOR THE DETECTION OF SUCH DAMAGE.

In plain language (FlightFinder summary)

The Federal Aviation Administration is asked to mandate full-scale structural fatigue testing to at least twice the projected economic service life for all future turbojet transport category airplanes, and to require similar testing for current airplanes that have not already reached that threshold. Based on the testing, inspection, and analysis, the FAA must also require manufacturers to identify structures vulnerable to multiple site damage and implement inspection programs suited to detect such damage.

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.
