NTSB Safety Recommendation — Aviation
Recommendation text
IT IS THEREFORE RECOMMENDED THAT MANDATORY INSPECTIONS SIMILAR TO THOSE REQUIRED BY THESE DIRECTIVES BE SPECIFIED FOR THE LOWER SPAR CAP OUTBOARD OF THE OUTER WING PANEL ATTACH POINT, INCLUDING THE WELDS JOINING THE ATTACH FITTING TO THE SPAR, THE WELDS AROUND THE BOLT HOLES, AND THE WELDS IN THE CLUSTER AND "FISH MOUTH" JOINT THAT EXTENDS TO A POINT APPROXIMATELY 21 INCHES OUTBOARD OF THE ATTACH POINT. PARTICULAR ATTENTION SHOULD BE GIVEN TO THE EDGES OF WELD BEADS THAT RUN TRANSVERSE TO THE LENGTH OF THE SPAR CAP. THESE INSPECTIONS SHOULD BE STARTED AS SOON AS POSSIBLE.
In plain language (FlightFinder summary)
Mandatory inspections are recommended for the lower spar cap outboard of the outer wing panel attach point, focusing on the welds of the attach fitting, bolt holes, and the cluster and fish mouth joint extending about 21 inches outboard. The edges of weld beads running transverse to the spar cap length require particular attention, and these inspections should begin as soon as possible.
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.
