FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE THE LOCAL CONTROLLER'S WORKLOAD AND THE EFFECT OF SUNGLARE ON THE PILOT OF N48977. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Midair collision, approach - vfr pattern - downwind - traffic advisory - inadequate, atc personnel(lcl/gnd/clnc) (cause) - excessive workload (task overload), atc personnel(lcl/gnd/clnc) (contributing factor) - atc clearance - improper, atc personnel(lcl/gnd/clnc) (cause) - light condition - sunglare (contributing factor) - visual lookout - inadequate, pilot in command(cfi) (cause) - visual lookout - inadequate, pilot of other aircraft (cause) - Midair collision, descent - normal - traffic advisory - inadequate, atc personnel(lcl/gnd/clnc) (cause) - excessive workload (task overload), atc personnel(lcl/gnd/clnc) (contributing factor) - atc clearance - improper, atc personnel(lcl/gnd/clnc) (cause) - visual lookout - inadequate, pilot in command (cause) - light condition - sunglare (contributing factor) - visual lookout - inadequate, pilot of other aircraft (cause) ## Analysis (aircraft 2) N7510H HAD CONTACTED TOWER SE OF ARPT ON RADIO FREQ USED FOR NORTH RUNWAY. FLT WAS CLEARED TO DESCEND THRU PATTERNS FOR RUNWAYS 9R AND 9L TO 500 FT FOR BANNER DROP. N48977 TOOK OFF ON 9R FOR TOUCH & GO, AND WAS USING RADIO FREQ FOR SOUTH RUNWAY. CONTROLLER GAVE N7510H TRAFFIC AS CESSNAS ON THE DOWNWIND FOR 9R. TWO OTHER CESSNAS WERE ON DWNWIND; N48977 HAD NOT TURNED DOWNWIND YET. PLT OF N7510H ACKNOWLEDGED TRAFFIC IN SIGHT. CONTROLLER GAVE CESSNAS ON DWNWIND TRAFFIC AS BANNER TOWERS INBND FROM SOUTH. CONTROLLER WAS WORKING A COMBINED POSITION OF TWO RUNWAYS AND TWO RADIO FREQ. THERE WERE SEVERAL ACFT IN EACH PATTERN. SHE STATED SHE DID NOT HAVE TIME TO GIVE SPECIFIC TRAFFIC INSTRUCTIONS TO N7510H AND N48977 DUE TO WORKLOAD. PLT IN CESSNA AHEAD OF N48977 STATED AS HE TURNED DWNWIND FOR 9R THE SUNGLARE REDUCED VISIBILITY. N7510H AND N48977 COLLIDED AT A 90 DEG ANGLE SHORTLY AFTER N48977 TURNED DOWNWIND FOR RUNWAY 9R. ## Aircraft 1 - Registration: [N48977](https://openairdocs.org/deregistered/N48977-1993-07-27), registration cancelled 1993-07-27, S/N 15281084 (OpenAirDocs) - Reported make and model: CESSNA 152 - Registry model: [Cessna 152](https://openairdocs.org/model/cessna-152) (registry code 2071835) (OpenAirDocs) - Category: Airplane - Serial number: 15281084 - Airframe hours: 6076 - Engines: LYCOMING O-235-L2C 110 horsepower reciprocating - Damage: Destroyed - Flight: Instructional, Part 91 - Registered owner: Crest One Aviation, Inc - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: 100 hour, January 25, 1990, 56 hours before - Airport: HWO, North Perry, runway 9R, 3,000 × 100 ft, asphalt ## Aircraft 2 - Registration: [N7510H](https://openairdocs.org/aircraft/N7510H), registered now, S/N 12-371, built 1946 (OpenAirDocs) - Reported make and model: PIPER PA-12 - Registry model: [Piper PA-12](https://openairdocs.org/model/piper-pa-12) (registry code 7101202) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 12-371 - Airframe hours: 11725 - Engines: LYCOMING O-320 150 horsepower reciprocating - Damage: Destroyed - Flight: Part 91 - Registered owner: Aerial Sign Company, Inc. - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, November 14, 1989, 255 hours before - Airport: HWO, North Perry ## Flight crew As NTSB recorded them.

Crossing mid field to drop banner was struck by N48977 on downwind. Both spun to ground. Busy tower failed separate 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.
