A FACTOR CONTRIBUTING TO THE ACCIDENT WAS THE FENCE. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - touch-and-go - performed, pilot in command - directional control - not maintained, pilot in command (cause) - On ground/water collision with object, takeoff - aborted - object - fence (contributing factor) ## Analysis THE STUDENT PILOT LOST DIRECTIONAL CONTROL OF THE AIRCRAFT WHEN THE NOSE PITCHED UP DURING THE APPLICATION OF POWER UPON HIS FIRST TOUCH AND GO LANDING ON RUNWAY 34. THE AIRCRAFT DIVERGED 40 DEGREES TO THE LEFT OF THE RUNWAY CENTERLINE AND THE PILOT WAS UNABLE TO REGAIN SUFFICIENT DIRECTIONAL CONTROL TO PREVENT THE AIRCRAFT FROM IMPACTING A BARBED WIRE FENCE WHICH PARALLELED THE RUNWAY. ## Factual narrative On September 30, 1993, at approximately 1800 hours mountain daylight time (MDT), a Piper PA-28-161, N21170, registered to and operated by Executive Aircraft International, and being flown by Francesco Consadori, a certificated student pilot, was substantially damaged during an aborted takeoff following a touch and go landing at the Bolinder Tooele Valley Airport, Tooele, Utah. The pilot was uninjured. Visual meteorological conditions prevailed and no flight plan had been filed. The flight, which was an instructional solo, was to have been operated in accordance with the requirements set forth in 14CFR91, and originated from the Salt Lake City International Airport at approximately 1730. The pilot reported that following the application of power after his first touch and go landing, the "aircraft nose pitched up quite suddenly and simultaneously (the) left wing dropped." The pilot retarded the throttle and attempted to abort the takeoff. He reported that the aircraft then "touched down on (the) edge of (the) runway heading approximately 40 degrees (to the) left of (the) runway heading" and began to roll off the runway and into the grass. The pilot attempted to control the aircraft by applying up elevator and rudder input. He then applied right brake in an unsuccessful attempt to avoid impacting a barbed wire fence which paralleled the runway. ## Aircraft - Registration: [N21170](https://openairdocs.org/deregistered/N21170-2018-01-16), registration cancelled 2018-01-16, S/N 28-7916029, built 1978 (OpenAirDocs) - Reported make and model: PIPER PA-28-161 - Registry model: [Piper PA-28-161](https://openairdocs.org/model/piper-pa-28-161) (registry code 7102803) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 28-7916029 - Airframe hours: 6547 - Engines: LYCOMING O-320-D3G 160 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Executive Aircraft Intnl - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, September 8, 1993, 47 hours before - Departed: SLC, SALT LAKE CITY, UT - Airport: TVY, Bolinder Tooele Valley, runway 34, 5,498 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
