# NTSB LAX06CA203: Aircraft Mfg & Dev. CH2000, N280AM, Chandler, AZ, June 10, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: June 10, 2006, 09:15 local (16:15 UTC) - Place: Chandler, AZ - Coordinates: 33.29861, -111.915275 - Nearby events: https://openairdocs.org/map.md?lat=33.2986&lon=-111.9153&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 October 3, 2006 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 63916 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX06CA203 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/63916/pdf - Page: https://openairdocs.org/ntsb/LAX06CA203 ## Probable cause The student pilot's failure to maintain directional control and the instructor's delayed remedial actions, which resulted in a collision with terrain during the initial takeoff climb. The instructor's inadequate supervision of the flight was also causal. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, takeoff - initial climb - soft field takeoff/procedure - attempted, dual student - directional control - not maintained, dual student (cause) - remedial action - delayed, pilot in command(cfi) (cause) - supervision - inadequate, pilot in command(cfi) (cause) - In flight collision with terrain/water, takeoff - initial climb - terrain condition - ground ## Analysis The airplane collided with terrain during the student pilot's attempted takeoff. During a soft-field takeoff with the airplane about 10 to 15 feet above ground level (agl), the student pilot increased the pitch attitude by raising the nose. The airplane yawed about 15 degrees to the right of the runway centerline and the certified flight instructor (CFI) momentarily waited for the student pilot to make corrective action. The airplane yawed an additional 15 degrees to the right before the CFI assumed the airplane controls. He applied left rudder and lowered the nose in an effort to maneuver the airplane back to the runway. The left wing and the tail impacted the ground, which the CFI believed was the main landing gear. The CFI continued the initial takeoff climb and shortly thereafter noticed the damage to the left wing. He returned to the airport for an uneventful landing. The CFI noted no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. ## Factual narrative The airplane collided with terrain during a soft-field takeoff. In a written statement, the certified flight instructor (CFI) reported that the purpose of the flight was for the student pilot to practice soft-field takeoffs and landings, which he had briefed the student for prior to departure. After rotation, with the airplane about 10 to 15 feet above ground level (agl), the student pilot raised the nose of the airplane high, akin to a short-field takeoff configuration. The airplane yawed about 15 degrees to the right of the runway centerline and the CFI momentarily waited for the student pilot to make corrective action. The CFI directed the student pilot to input left rudder, but the airplane yawed an additional 15 degrees to the right. The CFI further stated that he assumed the airplane controls. He applied left rudder, and lowered the nose in an effort to maneuver the airplane back to the runway. The left wing contacted the ground about 5 feet from the right edge of the runway and the tail subsequently impacted a grassy median to the right of the runway. The CFI believed that the airplane's main landing gear had contacted the ground and continued with the initial takeoff climb. Shortly thereafter, the CFI and student noticed the damage to the left wing and returned to the airport for an uneventful landing. The CFI noted no preimpact mechanical malfunctions or failures with the airplane or engine that would have precluded normal operation. ## Aircraft - Registration: [N280AM](https://openairdocs.org/aircraft/N280AM), registered now, S/N 20-1041, built 2004 (OpenAirDocs) - Reported make and model: Aircraft Mfg & Dev.

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.
