The NTSB's narrative final · quoted from the NTSB record

ACCORDING TO THE PLT, THE HELICOPTER TOOK OFF WITH UNDER 200 LBS OF FUEL INDICATING ON THE FUEL GAGE. FIFTEEN MINUTES AFTER TAKEOFF AT 125 FT AGL THE ENGINE OUT WARNING SYSTEM INDICATED AN ENGINE FAILURE. THE ACFT BEGAN TO ROTATE ABOUT ITS VETICAL AXIS AND DESCENDED. AT THIS POINT THE PLT OBSERVED THE FUEL GAGE TO BE 'ONE NEEDLE WIDTH BELOW THE 100 LB MARK.' THE PLT LOWERED THE COLLECTIVE ALMOST TO THE BOTTOM THEN PULLED IT ALL THE WAY UP JUST PRIOR TO IMPACT WHICH OCCURRED IN A DESCENT RATE OF 800 TO 1000 FPM. THE IMPACT BROKE THE RIGHT SKID AND THE HELICOPTER ROLLED OVER ON ITS RIGHT SIDE. AN INSPECTION OF THE ACFT FUEL SYSTEM FOLLOWING THE ACCIDENT REVEALED NO FUEL IN THE ANKS AND NOTHING WRONG WITH THE FUEL INDICATING SYSTEM.

About this page

Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number NYC84LA204.
