# NTSB LAX01LA202: Beech 76, N6046U, Prescott, AZ, June 2, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: June 2, 2001, 08:00 local (15:00 UTC) - Place: Prescott, AZ - Coordinates: 34.620426, -112.419639 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=34.6204&lon=-112.4196&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report November 28, 2001 - Report: Approved by Office Director - Parties: FAA Flight Standards District Office - NTSB case key (mKey): 52418 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX01LA202 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/52418/pdf - Page: https://openairdocs.org/ntsb/LAX01LA202 ## Probable cause The certified flight instructor's inadequate supervision of the student who failed to maintain adequate airspeed on approach, resulting in a stall/mush, and delayed remedial action when the flight instructor ordered a go-around. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - supervision - inadequate, pilot in command(cfi) (cause) - airspeed - not maintained, dual student (contributing factor) - stall/mush - inadvertent, dual student (contributing factor) - go-around - delayed, dual student (contributing factor) ## Analysis During a practice short field landing, the airplane landed hard, the propellers struck the ground, the wings buckled, and the firewall buckled. The student allowed the airplane to slow and an excessive sink rate developed. The flight instructor ordered a go-around, but the student was late reacting. The flight instructor then pushed the throttles forward herself but could not compensate for the airplane's high sink rate. ## Factual narrative On June 2, 2001, about 0800 hours mountain standard time, a Beech 76, N6046U, sustained substantial damage during a hard landing at Prescott, Arizona. Embry Riddle Aeronautical University was operating the airplane under the provisions of 14 CFR Part 91. The certified flight instructor and the private pilot certificated dual student were not injured. The local instructional flight departed Prescott about 0705. Visual meteorological conditions prevailed, and no flight plan had been filed. According the flight instructor, the student's previous two landings were "allright" except his final approaches were low. The flight instructor asked the student to make a short field landing and to "keep his glide a little high." On this approach, as the airplane neared the threshold, the student began to pull the power back and bring the nose up. The flight instructor told the student to "keep it down just a little longer." Again, the student retarded the power and raised the nose, and the instructor ordered a go-around. The student's reaction was slow and the instructor said "go-around" again. She then pushed the throttles forward herself but the airplane was sinking rapidly. The airplane landed hard and bounced. Both propellers struck the runway, both wings buckled in the flap hinge area, and a firewall buckled. ## Aircraft - Registration: N6046U (not matched to a registry record) - Reported make and model: Beech 76 - Category: Airplane - Serial number: ME-195 - Airframe hours: 8562.1 - Engines: Lycoming O360A1G6D 180 horsepower reciprocating; Lycoming LO360A1G6D 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Embry-Riddle Aeronautical University - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, May 31, 2001, 46.7 hours before - Departed: PRC, Prescott, AZ - Airport: PRC, Ernest A.

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.
