INADEQUATE MAINTENANCE/INSPECTION OF THE PROPELLER HUB (AFTER THE PROPELLER STRIKES) WAS CONSIDERED TO BE A CONTRIBUTING FACTOR. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, takeoff - initial climb - propeller system/accessories,hub - previous damage (cause) - maintenance,inspection - inadequate (contributing factor) - propeller system/accessories,hub - fatigue (cause) - propeller system/accessories,blade - separation - powerplant - vibration - Forced landing, maneuvering - turn to landing area (emergency) - Loss of control - in flight, maneuvering - turn to landing area (emergency) - airspeed(vs) - not maintained, pilot in command (cause) - stall/mush - inadvertent, pilot in command (cause) - In flight collision with terrain/water, descent - uncontrolled ## Analysis WITNESSES SAW THE ACFT CLIMB TO AN ALT OF ABOUT 500 TO 800 FT AGL AFTER TAKING OFF FROM RWY 32. AT ABOUT THAT TIME, THEY HEARD A LOUD NOISE FM THE ACFT, THEN THEY NOTED THAT THE ENG SOUND HAD CEASED. THE ACFT WAS OBSERVED TO MANEUVER AS IF THE PLT WAS TRYING TO RETURN TO THE RWY. THE PLT TRANSMITTED A 'MAYDAY' REPORT, STATING HE HAD 'LOST THE ENGINE.' WHILE TURNING BACK TO THE RWY, THE LEFT WING & NOSE OF THE ACFT DROPPED & THE PLANE ENTERED A LEFT DSCNDG TURN. IT IMPACTED THE GND IN A NR FLAT ATTITUDE WHILE IN A HIGH RATE OF DSCNT, THEN IT SLID INTO A TREE & BURNED. AN EXAM OF THE WRECKAGE REVEALED 1 PROP BLADE HAD SEPD FM THE HUB DRG FLT. A METALLURGICAL EXAM SHOWED THE HUB HAD FAILED FM FATIGUE. DRG THE PREVIOUS 87 HRS OF OPN, THE ACFT HAD BEEN INVOLVED IN TWO OCCURRENCES OF GEAR COLLAPSE, WHICH RESULTED IN PROP STRIKES WITH THE GND. ACCORDING TO RECORDS, THE HUB WAS INSPECTED & FOUND TO BE IN ACCORDANCE WITH THE REQUIREMENTS OF THE MANUFACTURER (MCCAULEY) & THE FAA. THE PLT'S PREVIOUS FLT TIME IN THIS MAKE/MODEL OF ACFT WAS NOT DETERMINED. ## Aircraft - Registration: [N24586](https://openairdocs.org/deregistered/N24586-2013-04-15), registration cancelled 2013-04-15, S/N MC-131, built 1972 (OpenAirDocs) - Reported make and model: BEECH A24R - Registry model: [Beech A24R](https://openairdocs.org/model/beech-a24r) (registry code 1151252) (OpenAirDocs) - Registry engine: [Lycoming I0360 series](https://openairdocs.org/engine/lycoming-i0360-series) (registry code 41515, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: MC-131 - Airframe hours: 1638 - Engines: LYCOMING IO-360-A1B 200 horsepower reciprocating - Damage: Destroyed - Fire: On-Ground - Flight: Personal, Part 91 - Registered owner: James H.

Propeller hub and blades separated from engine on climbout. Tried to turn back,stalled,crashed in residential area. 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.
