What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Aircraft came in with possible landing gear problems, aircraft did a fly by then landed runway, gear collapsed. (.4)the pilot reported getting an unsafe indication on the right main landing gear when the landing gear was lowered. The crew recycled the landing gear and got the same unsafe indication. The crew retracted the gear and diverted to Detroit. On arrival, the crew performed the 'landing gear abnormal extension checklist,' but the unsafe indication remained. The air traffic control tower reported that the gear appeared normal. During the landing, the right main landing gear retracted. The airplane slid sideways, striking a runway marker as it departed the runway, and came to rest in a field. Examination revealed that the right landing gear downlock mechanism could be overcome with physical force. Examination of the right landing gear actuator revealed that one of the six shims which separate the spacers and help guide the safety lock switch was out of position and lying on top of the lock assembly. (-23) the aircraft was diverted to Detroit metro airport (dtw) due to an un safe right landing gear (red) light. The aircraft touched down on runway 3R and the right landing gear collapsed at about 4800 feet from runway threshold. The aircraft skidded right and departed off the runway and struck the 5000 feet runway length marker with the left wing inboard slat. The aircraft continued to skid for about 700 feet and struck the runway visual range (RVR) equipment with the lower forward fuselage section and the cabin entry door. The aircraft came to rest on top of the RVR equipment.
As the FAA filed it
AIRCRAFT CAME IN WITH POSSIBLE LANDING GEAR PROBLEMS, AIRCRAFT DID A FLY BY THEN LANDED RUNWAY, GEAR COLLAPSED. (.4)THE PILOT REPORTED GETTING AN UNSAFE INDICATION ON THE RIGHT MAIN LANDING GEAR WHEN THE LANDING GEAR WAS LOWERED. THE CREW RECYCLED THE LANDING GEAR AND GOT THE SAME UNSAFE INDICATION. THE CREW RETRACTED THE GEAR AND DIVERTED TO DETROIT. ON ARRIVAL, THE CREW PERFORMED THE 'LANDING GEAR ABNORMAL EXTENSION CHECKLIST,' BUT THE UNSAFE INDICATION REMAINED. THE AIR TRAFFIC CONTROL TOWER REPORTED THAT THE GEAR APPEARED NORMAL. DURING THE LANDING, THE RIGHT MAIN LANDING GEAR RETRACTED. THE AIRPLANE SLID SIDEWAYS, STRIKING A RUNWAY MARKER AS IT DEPARTED THE RUNWAY, AND CAME TO REST IN A FIELD. EXAMINATION REVEALED THAT THE RIGHT LANDING GEAR DOWNLOCK MECHANISM COULD BE OVERCOME WITH PHYSICAL FORCE. EXAMINATION OF THE RIGHT LANDING GEAR ACTUATOR REVEALED THAT ONE OF THE SIX SHIMS WHICH SEPARATE THE SPACERS AND HELP GUIDE THE SAFETY LOCK SWITCH WAS OUT OF POSITION AND LYING ON TOP OF THE LOCK ASSEMBLY. (-23) THE AIRCRAFT WAS DIVERTED TO DETROIT METRO AIRPORT (DTW) DUE TO AN UN SAFE RIGHT LANDING GEAR (RED) LIGHT. THE AIRCRAFT TOUCHED DOWN ON RUNWAY 3R AND THE RIGHT LANDING GEAR COLLAPSED AT ABOUT 4800 FEET FROM RUNWAY THRESHOLD. THE AIRCRAFT SKIDDED RIGHT AND DEPARTED OFF THE RUNWAY AND STRUCK THE 5000 FEET RUNWAY LENGTH MARKER WITH THE LEFT WING INBOARD SLAT. THE AIRCRAFT CONTINUED TO SKID FOR ABOUT 700 FEET AND STRUCK THE RUNWAY VISUAL RANGE (RVR) EQUIPMENT WITH THE LOWER FORWARD FUSELAGE SECTION AND THE CABIN ENTRY DOOR. THE AIRCRAFT CAME TO REST ON TOP OF THE RVR EQUIPMENT.
