# NTSB LAX01LA139: Beech F-33A, N5544P, Mobile, AZ, April 5, 2001 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: April 5, 2001, 14:55 local (21:55 UTC) - Place: Mobile, AZ - Location: 33.1119° N, 112.2692° W: Placed by OpenAirDocs at BISHOP AIRFIELD (1AZ0), within about a mile (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=33.1119&lon=-112.2692&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 2 minor - Status: Completed, report November 28, 2001 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 52030 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX01LA139 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/52030/pdf - Page: https://openairdocs.org/ntsb/LAX01LA139 ## Probable cause The certified flight instructor's inadequate supervision of the dual student who failed to recognize the extent of the crosswind and lost directional control. A factor in the accident was the variable wind condition. ## 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 - weather condition - variable wind (contributing factor) - crosswind component - not recognized, dual student (cause) - aircraft control - not maintained, dual student (cause) - supervision - inadequate, pilot in command(cfi) (cause) - Dragged wing,rotor,pod,float or tail/skid, takeoff - initial climb - Roll over, takeoff - initial climb ## Analysis After a touch-and-go, when the airplane was about 10-15 feet off the runway, the right wing lifted, the left wing struck the runway, the airplane rolled inverted, and came to rest off the side of the runway. The student pilot made no wind correction inputs. The flight instructor tried to stabilize the airplane but was unsuccessful. A variable wind condition existed at the time of the accident. ## Factual narrative On April 5, 2001, at 1455 hours mountain standard time, a Beech F-33A, N5544P, sustained substantial damage when it dragged a wing and rolled over during a touch-and-go at Mobile Airport, Mobile, Arizona. The airplane was operated under the provisions of CFR 14 Part 91 by Airline Training Center Arizona as a local area instructional flight. The certified flight instructor and the dual student suffered minor injuries. Visual metrological conditions prevailed and no flight plan had been filed for the flight, which originated at the Phoenix Goodyear, Arizona, airport at 1420. The flight instructor reported that after a touch-and-go, when the airplane was about 10-15 feet off the runway, the right wing lifted. The student pilot made no wind correction inputs. The flight instructor tried to stabilize the airplane but was unsuccessful. The left wing struck the runway and the airplane rolled inverted and came to rest off the side of the runway. The flight instructor also reported that a variable wind condition existed at the airport. The air traffic at the uncontrolled airport self-directed a runway change minutes before the accident from runway 27 to runway 9 due to the variable wind. ## Aircraft - Registration: [N5544P](https://openairdocs.org/deregistered/N5544P-2002-03-01), registration cancelled 2002-03-01, S/N CE-1336, built 1989 (OpenAirDocs) - Reported make and model: Beech F-33A - Registry model: [Beech F33A](https://openairdocs.org/model/beech-f33a) (registry code 1151425) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: CE 1336 - Airframe hours: 12551 - Engines: Continental IO-520 285 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Airline Training Center Arizona Inc - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, March 30, 2001, 11 hours before - Departed: GYR, Goodyear, AZ - Destination: 1AZ0, Mobile, AZ - Airport: 1AZ0, Mobile Lufthansa Pvt, runway 9, 4,500 × 100 ft, asphalt ## Flight crew As NTSB recorded them.

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.
