# NTSB SEA96LA089: Cessna A185E, N185MP, Cascade, ID, May 5, 1996 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 5, 1996, 14:00 local (20:00 UTC) - Place: Cascade, ID - Coordinates: 44.590259, -115.56974 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=44.5903&lon=-115.5697&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report February 28, 1997 - Report: Approved by Office Director - NTSB case key (mKey): 42362 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA96LA089 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/42362/pdf - Page: https://openairdocs.org/ntsb/SEA96LA089 ## Probable cause the pilot's improper planning/decision, his failure to ensure that the airplane would maintain proper clearance from obstructions (trees), and his delay in aborting the takeoff. The soft/wet runway and tailwind were related factors. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, takeoff - initial climb - planning/decision - improper, pilot in command (cause) - airport facilities,runway/landing area condition - soft (contributing factor) - airport facilities,runway/landing area condition - wet (contributing factor) - weather condition - tailwind (contributing factor) - aborted takeoff - delayed, pilot in command (cause) - object - tree(s) - clearance - not attained, pilot in command (cause) ## Analysis The pilot reported that he initiated a soft field takeoff on a wet and soft grass strip. The airplane lifted off and the pilot leveled the airplane at 10 feet above ground level to increase speed. The pilot stated that the wind shifted to a tailwind and the airspeed dropped 10 knots. The airplane would not clear small trees at the end of the runway, and the pilot aborted the takeoff after colliding with the first trees. The airplane then landed approximately 300 feet from the end of the runway. ## Factual narrative On May 5, 1996, at 1400 mountain daylight time, a Cessna A185E, N185MP, registered to and operated by the pilot as a 14 CFR Part 91 personal flight, collided with trees during an aborted takeoff from a private airstrip located 31 miles east of Cascade, Idaho. Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane was substantially damaged and the airline transport pilot and his passenger were not injured. The intended destination for this flight was to Hailey, Idaho. The pilot reported that he had made a precautionary landing at the private grass airstrip due to weather. According to the pilot, after the weather improved, he executed a soft field takeoff but, after leveling off at 10 feet above ground level to increase airspeed, the aircraft would not accelerate above 60 miles per hour indicated airspeed. The pilot stated that he felt that there was now a tailwind. The aircraft's airspeed subsequently "dropped about 10 miles per hour" and, upon reaching the end of the runway, the aircraft collided with the tops of small trees before the pilot retarded the throttle and aborted the takeoff. The airplane landed approximately 300 feet off the end of the runway. The pilot reported that the grass strip was wet and soft with standing water at the north end. ## Aircraft - Registration: [N185MP](https://openairdocs.org/aircraft/N185MP), registered now, S/N 1851168, built 1967 (OpenAirDocs) - Reported make and model: Cessna A185E - Registry model: [Cessna A185E](https://openairdocs.org/model/cessna-a185e) (registry code 2072818) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18501168 - Airframe hours: 1594 - Engines: Continental IO-520D 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Mark S.

Premature liftoff from wet soft short grass strip. Unable accelerate. Crashed into trees off end of runway. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
