# NTSB LAX98LA082: Piper PA-34-200T, N47744, Chinle, AZ, January 29, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: January 29, 1998, 04:55 local (11:55 UTC) - Place: Chinle, AZ - Coordinates: 36.230392, -109.569221 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.2304&lon=-109.5692&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report December 8, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 30029 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX98LA082 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/30029/pdf - Page: https://openairdocs.org/ntsb/LAX98LA082 ## Probable cause the airport personnel's failure to provide an adequate perimeter barrier to prevent animals from entering the runway area. A factor in the accident was the dark night lighting conditions which hindered the pilot's ability to detect animals on the runway during the overflight and prior to touchdown. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - On ground/water collision with object, landing - roll - light condition - dark night (contributing factor) - airport facilities,perimeter fence - inadequate (cause) - other airport/runway maintenance - inadequate, airport personnel (cause) - object - animal(s) - Gear collapsed, landing - roll - landing gear,main gear - overload ## Analysis The night was dark with no moon. The pilot reported that because animals often entered into the airport boundary fence through a gate meant for people, he first overflew the airport at 500' agl to verify that the runway was clear. He reported that both the runway lights and aircraft landing lights were on. On the landing roll, the pilot made a correction to the left to avoid hitting a horse that was in front and to the right of him. As he straightened the airplane, a second horse appeared approximately 50 feet straight ahead of him. He reported that he 'didn't have time to react and we hit the horse with the left wing just left of the engine at about 70 knots.' After the impact, the airplane deflected left and headed towards the fence surrounding the airport. The pilot stated that he pressed right rudder and brake in order to avoid going through the fence and the plane entered into a left skid. The left main landing gear collapsed and the left propeller impacted the ground several times before the airplane came to a stop. ## Factual narrative On January 29, 1998, at 0455 hours mountain standard time, a Piper PA-34-200T, N47744, collided with a horse on the landing roll at the Chinle, Arizona, airport. The aircraft sustained substantial damage and the pilot and flight nurse were not injured. Visual meteorological conditions prevailed at the time of the accident and no flight plan was filed. The air ambulance flight had transported a patient to Flagstaff, Arizona, and was returning to Chinle as a 14 CFR Part 91 positioning flight at the time of the accident. The pilot reported to an Federal Aviation Administration inspector that animals frequently enter into the boundaries of the private airport through a gate meant for people's use. Prior to landing he over flew the field at 500 feet agl to verify that the runway was clear, and that both the runway lights and aircraft landing lights were on. The pilot reported that, "It was a very dark night, [and] the moon was not out." On the landing roll, he saw a horse just in front and slightly to his right so he made a left turn to get around it. As he straightened the airplane, a second horse appeared approximately 50 feet straight ahead of him. The pilot further stated that, "I didn't have time to react and we hit the horse with the left wing just left of the engine at about 70 knots." After impact, the airplane deflected to the left towards the fence that surrounded the airport. The pilot pressed the right rudder and brake but entered into a left skid. The left main landing gear then collapsed and the left propeller impacted the ground several times before the nose of the airplane came to a stop. ## Aircraft - Registration: [N47744](https://openairdocs.org/deregistered/N47744-2023-04-01), registration cancelled 2023-04-01, S/N 34-7870026 (OpenAirDocs) - Reported make and model: Piper PA-34-200T - Registry model: [Piper PA-34-200T](https://openairdocs.org/model/piper-pa-34-200t) (registry code 7103406) (OpenAirDocs) - Category: Airplane - Serial number: 34-7870026 - Airframe hours: 2648 - Engines: Continental TS10360E 200 horsepower reciprocating - Damage: Substantial damage - Flight: Positioning, Part 91 - Registered owner: Scenic Aviation Inc - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, December 12, 1997, 47 hours before - Departed: FLG, FLAGSTAFF, AZ - Airport: Q32, Chinle, runway 35, 4,200 × 60 ft, dirt ## Flight crew As NTSB recorded them.

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.
