Contributing to the accident was the airport personnel's decision to park the airplanes in close proximity to the taxiway. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Performance/control parameters: surface speed/braking](https://openairdocs.org/ntsb-findings/01062045): Aircraft › Aircraft oper/perf/capability · Incorrect use/operation (probable cause); cases with it: [Piper PA-28-236, 2 cases](https://openairdocs.org/ntsb-findings/01062045/cases.md?model=7102815), [All aircraft, 238 cases](https://openairdocs.org/ntsb-findings/01062045/cases.md) - [Towing and taxiing: taxiing](https://openairdocs.org/ntsb-findings/01010920): Aircraft › Aircraft handling/service · Incorrect use/operation (probable cause); cases with it: [Piper PA-28-236, 1 case](https://openairdocs.org/ntsb-findings/01010920/cases.md?model=7102815), [All aircraft, 27 cases](https://openairdocs.org/ntsb-findings/01010920/cases.md) - [Object/animal/substance: aircraft](https://openairdocs.org/ntsb-findings/03022040): Environmental issues › Physical environment · Not specified; cases with it: [Piper PA-28-236, 1 case](https://openairdocs.org/ntsb-findings/03022040/cases.md?model=7102815), [All aircraft, 116 cases](https://openairdocs.org/ntsb-findings/03022040/cases.md) - [Info processing/decision: decision making/judgment](https://openairdocs.org/ntsb-findings/02041520): Personnel issues › Action/decision · Airport personnel (probable cause); cases with it: [Piper PA-28-236, 5 cases](https://openairdocs.org/ntsb-findings/02041520/cases.md?model=7102815), [All aircraft, 3,098 cases](https://openairdocs.org/ntsb-findings/02041520/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight.

The private pilot was taxiing at approximately 15 miles beside the parked aircraft when the left wingtip of his airplane struck the propeller spinner of a parked aircraft. The pilot then hit two additional parked airplanes before he was able to stop his airplane. The nose of the first parked airplane measured six inches from the taxiway edge, the taxiway was 30 feet wide, and the taxiing airplane had a wingspan of 35 feet. ## Factual narrative Approximately 65 airplanes had flown to the airport for a fly-in. Excess airplanes that could not be parked on the ramp or in a nearby field were parked along the parallel taxiway, starting closest to the ramp. Terrain in the area the planes were parked sloped away from the taxiway, requiring airport personnel to park approximately 20 airplanes with their noses within three feet of the left edge of the taxiway. The planes were parked closer to the taxiway than they had during previous fly-ins due to recent rains softening the ground. The private pilot stated he was taxiing on the parallel taxiway to takeoff at idle power between 10 and 15 miles per hour and three feet right of centerline. He said he was cognizant of the wet ground off the taxiway and didn't want his wheels to go into the mud. The pilot cleared most of the parked airplanes when his left wingtip struck the propeller spinner of the third parked airplane from the end. The pilot then hit the last two parked airplanes before he was able to stop his airplane. The nose of the first parked airplane measured six inches from the taxiway edge, the taxiway was 30 feet wide, and the taxiing airplane had a wingspan of 35 feet. Airport personnel had issued a L-NOTAM for increased activity at the airport and airplanes parked near the taxiway. Interviews with the airport manager revealed the area between the taxiway and perimeter fence further southeast away from the ramp and accident location would allow airplanes to be pushed back approximately ten feet from the taxiway. Examination of the taxiing airplane revealed the leading edge of the left wing separated from the fuselage approximately six inches. ## Aircraft - Registration: [N8106M](https://openairdocs.org/aircraft/N8106M), registered now, S/N 28-8011006, built 1979 (OpenAirDocs) - Reported make and model: Piper PA-28-236 - Registry model: [Piper PA-28-236](https://openairdocs.org/model/piper-pa-28-236) (registry code 7102815) (OpenAirDocs) - Registry engine: [Lycoming 0-540 series](https://openairdocs.org/engine/lycoming-0-540-series) (registry code 41532, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 288011006 - Engines: Lycoming O-540-J3A5D reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Mcquay, doing business as Mcquay - Registered owner: Michael McQuay - Airworthiness certificate: Standard, Normal - Departed: Osage Beach, MO - Destination: KIWS, W.

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.
