RIGHT LANDING GEAR AND NOSE LANDING GEAR WERE SHEARED OFF DURING THE LANDING. FUSELAGE AFT FRAME AT VERTICAL FIN ATTACH POINT IS BENT FORWARD AND FUSELAGE SKIN WRINKLED. RUDDER AND VERTICAL STABILIZER APPEARED NORMAL. ENGINE CONTROL CONTINUITY VERIFIED ENGINE INSPECTION REVEALED VALID GEAR TRAIN CONTINUITY, VALVE TRAIN CONTINUITY, AND COMPRESSION PRESENT IN ALL CYLINDERS. SPARK PLUGS APPEARED TO INDICATE A NORMALLY RUNNING ENGINE. THERE DID NOT APPEAR TO BE BLOCKAGE IN THE CARBURATOR VENTURI. MAGNETOS WERE REMOVED TO VERIFY ROTATION AND APPEARED NORMAL. TESTED MAGNETOS, BOTH PRODUCED SPARK. PROPELLER IS A FIXED PITCH TYPE AND HAD MINOR DAMAGE ON ONE BLADE FROM IMPACT WITH POWER LINE. APPROXIMATELY 25 GALLONS OF FUEL WERE RECOVERED FROM AIRCRAFT. ANNUAL INSPECTION ON 01/01/2014 ACFT TT 1579.72 AIRCRAFT RECORDS AND LOGS WERE INSPECTED ON 09/30/2014 TEMPERATURE, DEW POINT, AND RELATIVE HUMIDITY FOR THE AREA OF THE ACCIDENT FLIGHT WAS OBTAINED THROUGH NOAA WEB SITE. A CARBURETOR ICING PROBABILITY CHART WAS USED TO DETERMINE IF CARBURETOR ICING MAY HAVE BEEN PRESENT. THE CARBURETOR ICING PROBABILITY CHART DEMONSTRATES THAT THIS AIRCRAFT WAS IN WEATHER CONDUCIVE TO CARBURETOR ICING. NO FURTHER ENTRIES ## 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 ERA14LA451](https://openairdocs.org/ntsb/ERA14LA451), Sep 21, 2014: Grumman American Avn. AA-5A (N26676), Homosassa, FL, substantial damage. Probable cause: A partial loss of engine power for reasons that could not be determined because engine examination did not reveal any anomalies that would have precluded normal operation. From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
