ON APRIL 19, 2022, INSTRUCTOR,^PRIVACY DATA OMITTED^ WAS COMPLETING A MULTI-ENGINE TRAINING FLIGHT, AT KLGB. FLYING A DIAMOND TWIN STAR (DA 42 NG; TAIL # N822SA), THEY HAD COMPLETED TWO SHORT FIELD TAKE-OFFS AND A SINGLE ENGINE ILS APPROACH UNDER SIMULATED INSTRUMENT CONDITIONS. THE FINAL MANEUVER WAS A SHORT FIELD LANDING. THE APPROACH WAS MADE WITH THE PRESCRIBED AIRSPEED (APPROXIMATELY 80 KIAS ON SHORT FINAL). THE AIRCRAFT TOUCHED DOWN ON RUNWAY 26L ON THE 1000 FOOT MARKERS AND BEGAN THEIR GROUND ROLL. THE RIGHT MAIN LANDING GEAR COLLAPSED DURING THE GROUND ROLL AND THE RIGHT PROPELLER AND RIGHT WINGTIP STRUCK THE GROUND.

LONG BEACH AIRPORT ^PRIVACY DATA OMITTED^ PERSONS PRESENT: ^PRIVACY DATA OMITTED^, DIAMOND REPRESENTITIVE (DR) ^PRIVACY DATA OMITTED^ DIRECTOR OF MAINTENANCE (DOM) ^PRIVACY DATA OMITTED^ RE: N822SA DIAMOND AIRCRAFT THE DIAMOND FIELD REPRESENTATIVE PERFORMED A VISUAL INSPECTION OF THE AFFECTED AREA. HE CONCLUDED THE LANDING BRACE COMPONENT HAD FAILED, BUT, IN HIS OPINION WAS A RESULT OF A HARD LANDING, NOT AS A RESULT OF POOR BONDING. THE DEBONING AREA DID SHOW SIGNS OF GOOD ADHESION AND CLEAN BREAK AWAY POINTS. THERE WERE NO SIGNS OF FAULTY ADHESION FROM THE ORIGINAL INSTALLATION ACCORDING TO THE DIAMOND FIELD REPRESENTATIVE. PRIOR TO THE (DR), THE (FAA) INSPECTOR PERFORMED A COIN TAP TEST AND VISUAL INSPECTION WITH A 10X MAGNIFICATION LENS, NO CRACKS NOTED ON THE LEFT LANDING GEAR BRACE. THE FIELD (DR) CONCURRED WITH THE FINDINGS OF THE TEST, AND WAS SATISFIED WITH A PORTION OF THE FINDINGS, THAT COMPONENT FAILURE DID OCCUR, BUT AS A RESULT OF A SUSPECTED HARD LANDING. THE DISCUSSION BETWEEN THE (FAA) AND (DR) FIELD REPREHENSIVE HAD CONCLUDED THAT, AFTER ELIMINATING ALL OTHER FACTUAL COMPONENTS OF THE INSPECTION, WE ARE ONLY LEFT WITH THE ?POSSIBILITY? OF A HARD LANDING. IT IS THE OPINION OF THE (FAA) INSPECTOR THE COMPONENT FAILED, WHETHER A HARD LANDING AIDED IN THE DEBONING IS STILL UNANSWERED. THE AIRCRAFT HAD RECENTLY CAME OUT OF A 100 HOUR/ANNUAL INSPECTION AND SHOW NO REPORTS OF DAMAGED OR FAULTY COMPONENTS RELATING TO THE LANDING GEAR. IT HAS SINCE FLOWN APPROXIMATELY 35 HOURS AND HAS HAD MULTIPLE PILOTS FLY THIS AIRCRAFT. THE ^PRIVACY DATA OMITTED^ HAD FLOWN THE AIRCRAFT A WEEK BEFORE THE GEAR FAILURE AND REPORT A SMOOTH LANDING WITHOUT ISSUES. THE LAST PILOT REPORTED A TEXT BOOK LANDINGS WITHOUT ISSUES. THE AIRCRAFT IS IN COMPLIANCE WITH ALL THE LATEST SERVICE BULLETINS AND ANY ADVISORY DIRECTIVES THAT MAY APPLY TO THE LANDING GEAR ASSEMBLY. A CONVERSATION VIA PHONE, TO^PRIVACY DATA OMITTED^, OF THE NATIONAL TRANSPORTATION SAFETY BOARD (NTSB), TOOK PLACE ABOUT THE AFOREMENTIONED TOPICS. THE (FAA) & (NTSB) HAVE BOTH AGREED TO RELEASE THE AIRCRAFT BACK TO ^PRIVACY DATA OMITTED^ SO HE MAY BEGIN REPAIRS. BASED ON THE FACTS PRESENTED ON THE CONCLUSION THAT, THE COMPONENT FAILED, WHETHER A HARD LANDING WAS THE RESULT STILL REMAINS UN PROVEN AT THIS TIME, BUT MAY HAVE AIDED IN THE FAILURE. THE (FAA) WILL BE CONTACTING ITS FAST TEAM AND HAVE CONTACT WITH THE OPERATOR OF ^PRIVACY DATA OMITTED^ IN REGARDS TO TRAINING FOR HARD LANDINGS AND REPORTING METHODS. ^PRIVACY DATA OMITTED^, DIAMOND REPRESENTATIVE WILL BE PROVIDING A STATEMENT OF HIS FINDING TO BOTH THE (FAA) AND (NTSB).IT IS OF THE OPINION OF THE INSPECTORS THAT FURTHER FLIGHT LOGS BE INVESTIGATED TO DETERMINE, IF A PAST PILOTS HAD EXPERIENCED A HARD LANDING AND MAY NOT HAVE REPORTED IT TO AID IN ANY FUTURE RELATED LANDING GEAR ISSUES.
