# NTSB FTW98LA200: Piper PA-24-400, N8536P, Jackson, WY, May 1, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 1, 1998, 10:30 local (16:30 UTC) - Place: Jackson, WY - Location: 43.6073° N, 110.7377° W: Placed by OpenAirDocs at JACKSON HOLE (JAC), within about a mile (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=43.6073&lon=-110.7377&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report February 15, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 20590 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW98LA200 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/20590/pdf - Page: https://openairdocs.org/ntsb/FTW98LA200 ## Probable cause the pilot's misjudgment of distance and speed, while approaching to land; his failure to attain a proper touchdown point for landing; and his failure to go around, while there was sufficient runway remaining. A related factor was the uneven terrain, which was encountered beyond the end of the runway. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - distance/speed - misjudged, pilot in command (cause) - proper touchdown point - not attained, pilot in command (cause) - go-around - not performed, pilot in command (cause) - On ground/water encounter with terrain/water, landing - roll - terrain condition - rough/uneven (contributing factor) ## Analysis The pilot said he was 'breaking in a new engine' and he did not reduce power fast enough. The airplane landed long on runway 18, which was 6,299 x 150 feet, asphalt, porous friction course overlay. He said he realized he was not going to be able to stop the airplane on the runway that remained, and also realized he did not have sufficient speed to abort the landing. Heavy braking caused the left tire to blow out, and the airplane departed the end of the runway. The left main landing gear collapsed when the airplane traversed a large dip at the end of the runway, and the airplane slid to a halt approximately 100 feet beyond. Airport officials reported finding 1,400 feet of skid marks. A light and variable wind was reported at the time of the accident. The pilot attributed the accident to his error in judgment. His recommendation: 'Always land near the threshold, leaving as much runway as possible. Pretty basic.' ## Factual narrative On May 1, 1998, approximately 1030 mountain daylight time, a Piper PA-24-400, N8536P, was substantially damaged when it collided with terrain while landing at Jackson, Wyoming. The private pilot and commercial-rated passenger were not injured. Visual meteorological conditions prevailed, and a VFR flight plan had been filed for the personal flight being conducted under Title 14 CFR Part 91. The flight originated at Provo, Utah, approximately 0900. The pilot had recently purchased the airplane from the passenger that was in the airplane. In his accident report, the pilot indicated he was "breaking in a new engine" and he did not reduce power fast enough. The airplane landed long on runway 18 (6,299 ft. x 150 ft., asphalt, porous friction course overlay). The pilot said he realized he was not going to be able to stop the airplane on the runway that remained, and also realized he did not have sufficient speed to abort the landing. Heavy braking caused the left tire to blow out, and the airplane departed the end of the runway. The left main landing gear collapsed when the airplane traversed a large dip at the end of the runway, and the airplane slid to a halt approximately 100 feet beyond. Airport officials reported finding 1,400 feet of skid marks. The pilot attributed the accident to "poor judgment" and his error. His recommendation: "Always land near the threshold, leaving as much runway as possible. Pretty basic." Later examination of the airplane by an FAA inspector revealed a wrinkled and dented left wing, a torn left flap, damaged elevator and both wing tips, two main tires blown out, and a collapsed landing gear. A light and variable wind was reported at the time of the accident. ## Aircraft - Registration: [N8536P](https://openairdocs.org/aircraft/N8536P), registered now, S/N 26-117, built 1965 (OpenAirDocs) - Reported make and model: Piper PA-24-400 - Registry model: [Piper PA-24-400](https://openairdocs.org/model/piper-pa-24-400) (registry code 7102408) (OpenAirDocs) - Registry engine: [Lycoming IO-720 series](https://openairdocs.org/engine/lycoming-io-720-series) (registry code 41546, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 26-117 - Airframe hours: 2986 - Engines: Lycoming IO-720-A1A 400 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Mark Sheranian - Airworthiness certificate: Standard, Normal - Last inspection: Annual, April 23, 1998, 3 hours before - Departed: PVU, PROVO, UT - Destination: JAC - Flight plan: VFR - Airport: JAC, Jackson Hole, runway 18, 6,299 × 150 ft, asphalt ## 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.
