VISUAL METEOROLOGICAL CONDITIONS PREVAILED AT THE TIME AND AN IFR FLIGHT PLAN WAS FILED FOR THE 14 CFR PART 91 BUSINESS FLIGHT. THE AIRPLANE SUSTAINED MINOR DAMAGE AND THE COMMERCIAL-RATED PILOT AND COPILOT, AND ONE PASSENGER WERE NOT INJURED. THE FLIGHT ORIGINATED ABOUT 1700 PACIFIC DAYLIGHT TIME FROM THE MCCARRAN INTERNATIONAL AIRPORT, LAS VEGAS, NEVADA. THE PILOT STATED THAT WHEN THE FLIGHT ENTERED THE TRAFFIC PATTERN AT THE DESTINATION AIRPORT AND THE LANDING GEAR WAS EXTENDED, THERE WAS NO DOWN AND LOCKED INDICATION FOR THE LEFT MAIN LANDING GEAR VIA THE NORMAL OR ALTERNATE INDICATION SYSTEMS. THE PILOT BRIEFED THE PASSENGER WHAT WAS OCCURRING AND WHAT WOULD OCCUR, ADVISED AIR TRAFFIC CONTROL OF THE SITUATION, CLIMBED AND ORBITED OVER THE AIRPORT AND CYCLED THE LANDING GEAR THREE OR FOUR TIMES. THERE WAS NO DOWN AND LOCKED INDICATION FROM THE LEFT MAIN LANDING GEAR. AT THE PILOT'S REQUEST, THE FLIGHT WAS VECTORED TO THE NEAREST AIRPORT WITH FACILITIES, WHICH WAS THE FAYETTEVILLE AIRPOR T. THE PILOT PERFORMED SIX FLY-BYS OF THE AIR TRAFFIC CONTROL TOWER LOCATED THERE FOR CONFIRMATION OF THE POSITION OF THE LEFT MAIN LANDING GEAR. THE PILOT THEN INITIATED A CLIMB TO 8,000 FEET WHERE HE INITIATED A SERIES OF "G" LOADING MANEUVERS AND PARABOLIC ARCS WITH SIMULTANEOUS YAW AND GEAR EXTENSION WITH NO SUCCESS IN EXTENDING THE LEFT MAIN LANDING GEAR. THE FLIGHT RETURNED FOR LANDING AT THE FAYETTEVILLE AIRPORT AND AFTER TOUCHDOWN FIRST ON THE RIGHT MAIN LANDING GEAR, THE LEFT WING BEGAN TO SETTLE LOWER THAN USUAL. THE PILOT INITIATED A GO-AROUND, AGAIN BRIEFED THE PASSENGER, AND RETURNED FOR LANDING. AFTER TOUCHDOWN, THE AIRPLANE REMAINED ON THE RUNWAY WITH THE APPLICATION OF RIGHT BRAKE AND RUDDER INPUT. PRELIMINARY EXAMINATION OF THE LEFT MAIIN LANDING GEAR REVEALED THAT THE MAIN GEAR JACK CYLINDER HEAD PART NUMBER AIR 111506, EXHIBITED BROKEN LUGS AT THE JACK CYLINDER HEAD LOCATION.

THE GEAR COULD NOT BE EXTENDED. THE AIRPLANE WAS LANDED WITH THE LEFT MAIN LANDING GEAR RETRACTED. EXAMINATION OF THE AIRPLANE REVEALED THAT THE LUGS ON THE CYLINDER HEAD OF THE LEFT MAIN LANDING GEAR JACK WERE FRACTURED. METALLURGICAL EXAMINATION OF THE FRACTURED LUGS OF THE CYLINDER HEAD REVEALED OVERSTRESS FAILURE; NO EVIDENCE OF PROGRESSIVE (FATIGUE OR STRESS CORROSION) CRACKING WAS OBSERVED. THE CYLINDER HEAD IS A 5,000 CYCLE LIFE LIMITED COMPONENT AND THE FAILED CYLINDER HEAD WHICH WAS INSTALLED WHEN THE AIRPLANE WAS MANUFACTURED, HAD ACCUMULATED 4,751 CYCLES AT THE TIME OF FAILURE INCLUDING THE ACCIDENT LANDING. THE JACK ATTACHMENT AND SURROUNDING AREA REQUIRED TO BE INSPECTED EVERY 600 HOURS, WAS INSPECTED LAST 348 HOURS AND 299 CYCLES EARLIER; NO DISCREPANCIES WERE NOTED. ## The NTSB's investigation of this event (1) From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB MIA00LA013](https://openairdocs.org/ntsb/MIA00LA013), Oct 19, 1999: British Aerospace HS 125-700A (N34GG), Fayetteville, NC, substantial damage.
