# NTSB DEN99LA118: Piper PA-25-235, N7614Z, Delta, UT, July 12, 1999 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 12, 1999, 08:00 local (14:00 UTC) - Place: Delta, UT - Coordinates: 39.289276, -112.559455 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.2893&lon=-112.5595&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report June 22, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 46787 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN99LA118 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/46787/pdf - Page: https://openairdocs.org/ntsb/DEN99LA118 ## Probable cause The pilot's delayed aborted takeoff. A factor was the high density altitude. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, takeoff - aborted - aborted takeoff - delayed, pilot in command (cause) - weather condition - high density altitude (contributing factor) - On ground/water encounter with terrain/water, takeoff - roll/run - terrain condition - berm ## Analysis The pilot said that this was his first season as an aerial application pilot, and this was his first takeoff from this airstrip. He was on takeoff roll with 80 gallons of applicant and 30 gallons of fuel; and, the takeoff 'seemed long to me.' He reduced the throttle to idle, and began braking. The airplane went beyond the end of the runway, hit an earthen berm, and separated the right main landing gear from the fuselage. One propeller blade and the right wing tip were bent. The pilot reported that the airstrip's elevation was 5,000 feet, the temperature was 70 degrees F., and the altimeter was 30.02 inches of mercury. The density altitude was 6,795 feet. The airplane's maximum gross weight was 2,900 pounds, and the airplane's actual weight was undetermined. ## Factual narrative On July 12, 1999, approximately 0800 mountain daylight time, a Piper PA-25-235 Pawnee, N7614Z, was substantially damaged when it struck terrain during an aborted takeoff near Delta, Utah. The commercial pilot, the sole occupant, was not injured. The aircraft was being operated by Spanish Fork Flying Service, Spanish Fork, Utah, under Title 14 CFR part 137. Visual meteorological conditions prevailed for the local aerial application flight which was originating at the time of the accident. No flight plan had been filed. The pilot said that this was his first season as an aerial application pilot, and this was his first takeoff from this airstrip. He said that he was on takeoff roll with 80 gallons of applicant and 30 gallons of fuel; he reported that the takeoff "seemed long to him." He reduced the throttle to idle, and began braking. The airplane went beyond the end of the runway, hit an earthen berm, and separated the right main landing gear from the fuselage. One propeller blade and the right wing tip were bent. The pilot reported that the airstrip's elevation was 5,000 feet, the temperature was 70 degrees F., and the altimeter was 30.02 inches of mercury. The density altitude was 6,795 feet. The airplane's maximum gross weight was 2,900 pounds, and the actual weight at takeoff was undetermined. ## Aircraft - Registration: [N7614Z](https://openairdocs.org/deregistered/N7614Z-2009-10-15), registration cancelled 2009-10-15, S/N 25-3723, built 1965 (OpenAirDocs) - Reported make and model: Piper PA-25-235 - Registry model: [Piper PA-25-235](https://openairdocs.org/model/piper-pa-25-235) (registry code 7102504) (OpenAirDocs) - Registry engine: [Lycoming 0-540 series](https://openairdocs.org/engine/lycoming-0-540-series) (registry code 41532, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 25-3723 - Airframe hours: 7243 - Engines: Lycoming O-540-B2B5 235 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: Spanish Fork Flying Service - Airworthiness certificate: Special, Restricted (Special) - Last inspection: Annual, June 1, 1999 - Departed: NONE - Airport: NONE, Dirt Ag Strip ## Flight crew As NTSB recorded them.
